The Real Truth About Off-Grid Solar: 5 Eye-Opening Revelations

The Real Truth About Off-Grid Solar: 5 Eye-Opening Revelations

Going off-grid with solar power seems idyllic, being energy independent and untethered from utility companies. But the reality of maintaining an off-grid solar system has some unexpected challenges. Here are 5 eye-opening revelations about off-grid solar that everyone should know.

Key Takeaways

  • Off-grid requires large battery banks for overnight power storage
  • Frequent battery maintenance is essential to longevity
  • Supplemental sources may be needed during low-light periods
  • Staying connected still requires a generator or shore power
  • Sizing the system properly is paramount to avoid shortfalls

Huge Battery Banks Required

Without a grid to fall back on, off-grid solar systems must store enough energy reserve in batteries to power your home around the clock, especially overnight. This requires a drastically larger battery bank than grid-tied systems.

High Battery Maintenance Needs

Off-grid batteries are extremely sensitive to operating conditions and require regular maintenance like checking fluid levels, cleaning terminals, equalizing charges, etc. Lack of diligent maintenance shortens battery lifespan significantly.

Supplemental Power Often Necessary

During extended cloudy periods, the solar system may not sufficiently recharge batteries, requiring supplemental charging from a generator or other energy sources so things don’t go dark.

Staying Connected Still Requires Work

Living off-grid doesn’t necessarily mean you want to stay digitally disconnected. Running modem/routers, WiFi, and entertainment devices still requires firing up generators regularly to top off batteries.

Precise Load Calculations Are Essential

Taking the time to calculate your electrical loads precisely ensures properly sizing the solar array, battery bank, inverter and other system components. Undersizing can lead to critical shortfalls.

Conclusion

While the concept of off-grid living is appealing, the realities involve unexpected system maintenance, generator reliance, frequent charging, and precise load calculations. Understanding these key revelations helps set proper expectations.

Hot Take

  • Remote properties mean technicians can’t easily come troubleshoot issues – DIY skills are critical.
  • Generator fuel can become costly if used regularly as backup power.
  • Cloudy weather lasting over a week could mean reverting to candles until skies clear.
  • Don’t forget to factor in seasonal load changes – shorter winter days require more stored energy.

all right it’s the middle of winter and it’s a beautiful winter day I thought it would be a good time to do an updated

0:06video about my off-grid solar system this is the truth about off-grid solar

0:13[Music]

0:24alright so in this video we’re going to cover five things we’re gonna it’s gonna

0:30be a big big tour and uh at the end of it I’m going to answer some common questions that I get all the time but

0:36we’re gonna talk about firstly why I’m off grid I’m going to provide some context to my

0:44experience with this system and then we’re going to look deep take a close look at the system all its components

0:49we’re going to talk about seasons of the system because a lot of people ask you know what’s it like in

0:57the summer what’s it like in the winter and talk all about that I’ve got examples of peak production at every

1:02time of the year as well as lowest production for every time of the year I want to correct the record too that’s a

1:09big part of why I’m I’m doing this video or a motivation for it is I had a video come out in the summer and I said some

1:14things that were Incorrect and so I want to correct the record on that and then lastly I want to answer some of the most

1:20common questions that I get about this system all right so let’s first start

1:25while I’m out here let’s talk about why we’re off grid this is a this is a

1:31question that I think it’s important to ask I think it’s important to always start with the why with something why

1:37are you doing this and I see people making comments about

1:42um solar being a joke as far as environmental friendliness and and and

1:48and all of that stuff carbon footprint and to be honest I don’t I don’t care about any of that stuff I’m no

1:54I’m no uh worshiper of Saint Greta if you will though I do believe in being a

2:01good Steward of the Earth but I also believe we have to be practical so I’m not opposed to fossil fuels or petroleum

2:08I don’t even like the term fossil fuels I’m not opposed to any of that uh for me solar is all about freedom and being

2:16off-grid is all about freedom I don’t want Claus Schwab turning off my electricity I don’t want to have to go

2:23through the rationing of electricity which are um malevolent dictators at the

2:30world economic Forum would want us to do so for us being off grid is all about Freedom it’s all about having that

2:36freedom but with freedom comes responsibility and with responsibility also becomes limitations and so it’s

2:42just the reality of the system um and when we get into the details of the system I can explain how it affects

2:49our life and all that we’ll talk about how how with the loads that we use and whatnot but in a nutshell it’s all about

2:56Freedom it’s all about having power and when I want it when I need it and making

3:03sure that I control that and I own it and so again that comes with responsibility becomes because it means

3:09that I have to manage it it’s not like when you’re living on the grid with a house that has a 200 amp service and you

3:15can just do anything you want at any time you want this has limitations we can only do laundry at certain times I

3:23mean we can do it anytime if we want if we run want to run the generator but on a really soaked in cloudy day

3:30unless I want to burn diesel and we’ll look at the generator and stuff in this video unless I want to burn diesel I got

3:36to wait until it’s sunny and it’s actually not that bad of a limitation I actually really enjoy living seasonally

3:43I’ve always talked about that in my videos for many years just being a farmer and and and living with the ebb

3:51and flow and the equilibrium and the limitations and the benefits of the changing seasons and so for me energy

3:59fits into that piece just lovely so it’s it’s all about those things but

4:05primarily it’s it’s the freedom it’s I have power and nobody can just

4:11turn this off you know as long as I can get daylight every day it doesn’t have to be direct Sunshine either I have

4:17electricity and and for the most part I have what I need most of the time and

4:23we’ll kind of talk later in this video about what those what those things look like in more detail but in a nutshell

4:28it’s about Freedom so since we’re out here we’ll start with the um

4:34greater context of the system and we’ll talk about then we’ll go and look at the system more in detail so my context with

4:43solar is I’ve actually used lived with solar power for a number

4:48of years because I bought this property in September 2020 and uh even this

4:56property came with a tiny little solar system but even previous to that our house in Kelowna had a grid tied solar

5:04system with two Tesla power walls it was an 11 and a half kilowatt system and I

5:10had that for about five years and I’d seen the ebb and flow I’d seen what are winters like what are summers like and

5:16that system was very very different than this one and I learned a lot from that system which lent which basically led me

5:24to do the system that I’ve done here and it’s why the system is the size it is it’s why I’ve

5:31uh not put these on the roof of the buildings um it’s uh yeah it’s really

5:39led me here and and really my context was getting started is I wanted to size

5:45this system based on what I need to get through winter with the ultimate goal of

5:51not even need to needing to run a generator but as you’ll see for at least one month of the year that’s very

5:57difficult to do and I I don’t want to say it’s impossible but it’s it’s

6:03um without spending out a massive amount of money it’s it’s almost pointless and we’ll

6:08talk about that later uh in this video but that was my context coming in it’s like we live in a cold climate we’re in

6:14southern British Columbia Canada and we’re high elevation we’re in a mountain which actually is better overall overall

6:21we’re we’re we’re we’re sunny at least sunnier than where I was in the Okanagan Valley Kelowna BC Canada gets very

6:28socked in the winter and the clouds sit in the valley and you you get clouds for

6:34months at a time the Cloudy periods for for many months whereas up here there’s

6:39really only a month so far out of the two years that I’ve lived here um where there is uh where you’re really

6:47socked in and we certainly saw that we had a period of time was December 21st

6:52until January 19th no direct Sunshine whatsoever there might have been a

6:58couple bursts of sunshine here and there but but we ran the generator for that period of time and we burned 150 liters

7:05of diesel for that almost 30-day period and um diesel at a dollar eighty a liter it

7:13wasn’t so bad it was you know just call it two bucks call it 300 dollars for that that one month period you know

7:21most people pay more than that for their utility bills in the winter when you combine you know when you look at

7:27everything so it wasn’t really that big of a deal and um

7:33so that’s that’s kind of where where we’re coming from with all this is

7:39I want to have power in the winter um within reason and so

7:46yeah let’s now talk about the system in detail start one might as well start here

7:52because we’re outside we’ll go inside and look at the inverters and charge controllers and batteries and all that but let’s start here so this is a 20

7:59kilowatt system it’s actually 20.88 to be exact we have 48 panels so

8:05there’s 16 here 16 here and 16 here they’re on three different rigs they’re

8:12not mounted to the buildings um here a couple reasons for that one is

8:18my buildings are all passive solar so this is south and this building the

8:24front of it is a greenhouse and the roof slopes back to the north so you can’t really Mount solar panels on there

8:32um and then same thing with the house it’s not finished yet but it’s a pasta solar house it’ll be the same height as

8:37this same roof so mounting on the roof doesn’t make any sense also mounting on the roof

8:43really sucks if you’re in a snowy climate because these panels have to be scraped off regularly in the winter time

8:50the first part of winter starting November 4th for us boom snow I was out

8:56here at least every second day scraping these off we’ve had so much snow this winter now it’s really slowed down it’s

9:02really warming up it’s getting sunnier again which is great but um so that’s why they’re not on the

9:08roof so and they are three separate rigs now the reason there’s three separate rigs is just simply geography if I was

9:16on a in a flat area and I had lots of open space and all kinds of access to

9:21get around things then sure I would have had this all in one run you still have to when I adjust them

9:28seasonally which I’ll show you in a minute you still have to do partitions at a time you can’t move a whole 48

9:36panel rig uh very easily so they’re on three separate rigs for that reason

9:41mostly it’s geography but also I wanted to try out

9:47having different angles um at the Sun so basically we have a 15

9:54degrees to the east so this panel is where are we here this panel right behind me here this one is southeast

10:02South Southeast I guess you could call it this one is true South and then this

10:07one is South Southwest so 15 degrees to the West 15 degrees to the east

10:13I love the 15 degrees to the East and I love the South I’ll probably I’m gonna

10:18most likely change this one this summer and just move it on its uh it’s on these

10:24big concrete pads and I’ve got enough play on there that I can actually just move the steel racking on top and angle

10:30it straight South but I love the the southeast and the main idea with that is

10:36that in the morning time like right now um and even earlier

10:42we’re up as a family we’re using utilities lights are on it’s still dark in the winter running a blender running

10:50stuff in the kitchen our our stove is gas and wood

10:55so you know we’re not using electricity for for stoves in the winter we do in

11:00the summer though and because we have so much excess electricity but we basically have a lot of demand in the morning

11:07and yeah I could just pull that off the batteries no problem but if you want longevity in a solar system with

11:13batteries the less you cycle your batteries the better so I can have power

11:18coming in and it can go straight to the inverter which then it would just go to the load or it can go straight DC to the

11:25battery and just bank and so I would rather in

11:30the morning or I would rather optimally use solar live right off the and convert

11:38it to AC right away off the solar panels because then you’re not cycling your batteries as much so that’s the reason

11:44for that that panel being where it is is that just over time I’m going to get

11:49more electricity off it in the morning and then of course the South ones will give me electricity throughout the day

11:56as it’s needed but it’s quite significant actually between on average in the winter so call

12:02it about a two and a half three month period in the winter time yes the day lengths change as you approach the

12:08winter solstice and you exit the winter solstice now I think days are getting longer but on average between eight I

12:16call it 7 30 and 9 30 a.m in the winter time this panel the Eastern panel is

12:22producing about a thousand to two thousand more watts than just the South panel so that’s really good because then

12:30I get a lot of electricity in the morning that I can use that I’m not taking off the batteries so that’s the idea with that

12:37um and yeah I’m gonna move the Western one later in the season but let me just show you kind of the basis of these

12:44panel rigs so each rig is actually two rigs so there’s

12:49on half of it there’s eight panels on the other half there’s eight and uh there’s three A-frames here

12:57I’ll show you this one because it has less stuff on it so there’s there’s three kind of

13:02A-frames here and uh you can see there’s one big rig there of of eight solar

13:09panels and then one there these are 435 watt panels and 435 times 48 is 20.88 so that’s the

13:19total amount of voltage or or wattage that our system will put out and so these these racks have three

13:27positions right now they’re in Winter mode which is fairly straight like this and then there’s a spring and fall mode

13:33that’s at about 45 and then there’s a summer mode which is kind of further back and then there’s a maintenance mode

13:39if I want to get them just flat to to do something and they’re perfectly balanced and and it’s really sweet because I can

13:46just move these myself I just move one rig at a time and it takes me probably 10 minutes to move all of them and I

13:51have to do it four times a year so it’s not that big of a deal later in this video I’ll address a common

13:57question which comes up as is why I don’t have these these follow the Sun and I will address that near the end of

14:04this video when we get to the the common questions but um that’s basically how these work

14:09and you know there’s a lot of snow down here right now but you can kind of see there these are these concrete pavers

14:16that I poured they’re about they’re about 18 inches to three feet deep because our ground isn’t even here

14:24um so it’s a lot of concrete it’s about six thousand pounds of concrete uh for each pad meaning that each rack total

14:31rack is anchored to 18 000 pounds of concrete so these aren’t going anywhere

14:36we also drilled into the Rock because my whole property is is bedrock for the most part especially this part so when

14:44we when we when we formed out these concrete pads we also Hilty drilled into the Bedrock

14:51and then put ready uh not ready Rod but um rebar with epoxy into the concrete so

14:57these concrete pads are not moving anywhere and I’ve seen some pretty serious winds up here and these things

15:03haven’t even moved and I there’s times where I’ve been really nervous because it’s been windy as hell things are blowing around probably

15:10I mean we don’t get crazy winds out here but probably 30 or 40 kilometer winds

15:16where I’m I’m feeling a bit nervous and things are moving around and stuff and

15:21these haven’t moved at all even in Winter mode uh and we’ve seen storms like that in the summer basically every

15:27time of the year so so they’re they’re really anchored down well now

15:33um what else can I say about these panels so each of these panels is connected to a charge call controller

15:40inside and we’ll go look at that so just coming into my garage here

15:46this is where the system is all housed so these are our charge controllers there’s three of them and each of these

15:52is connected to one of the rigs out here

15:58and there’s kind of four

16:04five main components of this system there’s the charge controllers the inverters the batteries

16:11the the technology that ties it all together and then the generator which

16:17will go out and look at as well so right now we’ve got solar coming in

16:23and as solar comes in see here’s a this I’ve got my software open here which is a great explanation of all this we can

16:29Circle back to that in a minute basically this is what’s bringing in the Solar so these are connected to the

16:36solar right now and at the moment this is real time we’ve got 11.3 kilowatts 11.1 kilowatts

16:44coming in from solar that’s a charge controller so solar is coming in

16:49it’s coming towards the inverters some of it’s going to the batteries

16:55directly because I’m actually charging my Tesla right now which is taking about

17:01six kilowatts and that 0.8 is basically the rest of our load and so some electricity is coming in

17:09going directly to the batteries and charging my batteries they’re almost full we’ve been relatively Sunny lately

17:14so they’re not really going down past 75 lately so some of that’s going to top up the batteries the rest of it’s going to

17:21the inverter and that inverter is turning the DC which solar comes in as direct current and it goes into the

17:28batteries as direct current comes the inverters there’s a little bit loss in the energy loss you can see there’s

17:34seven kilowatts coming into the inverters and then there’s 6.7 so you lose I think it’s around

17:41a couple percentage points of of kilowatts when you convert DC to AC and

17:48that’s how that goes and then here’s my generator and so if I were to fire that up you’d see lines going from this going

17:54into the inverter as well and it also will go to right to the batteries as

18:00well and so these are those charge controllers I have three of them and

18:06I’ve built optionality into the system that I could add a whole other charge controller and a whole other panel rig

18:13in fact I could actually add about 24 more panels to the system if I wanted to

18:18but you know the system isn’t cheap and we will discuss the price of it I’ll let

18:24you know what all this has cost so anyways we’ve got our charge controllers then we’ve got our inverters here and so

18:31basically each of these invert this inverter uh one of these is connected to two

18:37charge controllers and one of them is connected to one and so that’s why I have the flexibility like if I wanted to

18:42add another charge controller and another 24 panels the 16 to 24 panels it would go to the one of these inverters

18:49the reason that they’re connected to the inverters is that when when power comes in it can either

18:55go directly to the batteries or it can go to the inverters and so if you’re using it live you need to have your charge controllers

19:02running through these inverters in some way I’m not an electrician and I can’t explain to you exactly how this is all

19:08wired but the the principle of it is fairly straightforward and especially when you can understand this graph it

19:14kind of makes sense and so those inverters right now we can see this is showing what I’m

19:21consuming so this inverter is putting out uh 3.5 kilowatts and this one’s put

19:26a note 3.2 basically that’s divided amongst the load

19:32um in in the system and so this is my main panel uh once our house is finished

19:37there’ll be another sub panel in there off this but that’s kind of what happens now

19:43these are the batteries uh total here we have 96 kilowatt hours of storage these

19:50are called life power and these came from a company in Texas called Signature solar and I’m not promoting their them

19:57any I’m just telling you where I got them and this whole battery bank at the time cost me about 27 000 USD delivered

20:08um I don’t know what that price is right now but this is 96 kilowatt hours so they’re

20:14about 30 what would that be 32 kilowatt hours per uh rack here and there’s six

20:22in each rack so there’s 18 batteries total and so this amount of battery

20:28storage this is a lot this is this system in general is a big system but

20:33um these batteries really allow me to it basically at the darkest period of the

20:39Year these batteries allow me to go about four or five days

20:45without a lot of sun and that could be any collecting anywhere between the

20:50lowest I’ve seen is 1.8 kilowatt hours in a day up to maybe 10 kilowatt hours

20:55in a day this will carry me for about four or five days of course it depends

21:01on your loads and all that but that’s kind of how that works out all right now let’s discuss loads where do we send

21:07electricity how much do we use this is probably the most important thing if you’re going to be off grid to consider

21:13because when you want to increase the size of your system it’s just costs money and

21:18it’s it’s expensive um and so the most cost effective way to

21:24maximize your system is to use efficient appliances or tools make sure things

21:31there’s not Phantom drain that you’ve just got things plugged in that are just sucking little bits of power

21:37um you know yeah basically just just use less power also adjust your behavior use

21:46things according to the day you know so for example I’m not going to charge my

21:51Tesla when it’s not Sunny I’m not going to burn diesel to charge my Tesla that’s

21:56a very inefficient conversion also you’re not going to use heat with

22:03electricity that is the most inefficient conversion unless for certain times of the year so for six months of the year

22:10we’re going to have a heat pump in the house and which will give us a little

22:16bit of heat when we need it not a lot but just when we need it if we need it but it’ll also function as air conditioning you can have air

22:21conditioning when your solar in the summer especially with the size of our system no problem

22:28um but generally speaking our loads are about 800 watts steady now that seems

22:35like a lot and it kind of is because I kind of spec this system in a way that I could we could live our

22:42lives the way you would normally within a city being on the grid within reason

22:48so that 800 watts um actually it’s not 800 watts

22:54consistent it’s about 800 watts of consistent draw during the day and at night time it goes

23:01down to about three or four hundred because I have things on well no it goes

23:06down to no it’ll go down to about 600 at night uh and be about 800 consistent and then

23:13you’ll have fluctuations in there but so we need to get through a day we need somewhere

23:19between 10 to 15 kilowatt hours of power and for most of the year

23:25like 10 months 10 and a half months of the year the solar system gosh it’s really 11

23:32months of the year I mean two years into it now it’s about 11 months of the year this system gives me everything I need

23:40all the time um the only time we need to run the generator is at that darkest period

23:45which we just went through um but we’ve done things like uh we you know we get our internet from Elon Musk

23:53we have starlink it’s really the only internet we can get this in this remote of a location and I also make a living

24:00online so I don’t really have a lot of options so but it can this thing sucks a

24:06lot of power it’s somewhere around 200 volts uh 200 watts per hour like it is a

24:12major suck and so what I do with it is I have it on a timer and this timer

24:19just one of these classic plug-in timers manual it turns off when we sleep and I

24:25even have it turn off throughout the day usually by about

24:3011 till 1 p.m we’re all like nobody’s using the internet sometimes I I will

24:37and then I’ll have to turn it back on but that’s another way I’ve found that I can shave off some wattage uh draining

24:44the system by just doing that that’s quite significant other than that we have

24:49um three or four freezers large chest freezers that are plugged in 24 7. the

24:55nice thing about freezers is they actually consume less power in the winter because they don’t need to cool the product down as much so that that’s

25:02good but they are a constant draw we have a refrigerator in the cabin that we’re currently living in that isn’t

25:08particularly efficient but it but it’s you know a new fridge

25:14um we have lights we have computer equipment and things that I use in my

25:20office we have an electric car that we plug in from from time to time

25:25um we also have two wood stoves that we use that have fans in them and I have

25:32one in the garage here and I have another one in the cabin and they suck a

25:38little bit of power not that much um and we’re also we also have fans in

25:43the greenhouse um I have a fan that that runs 24 7 to

25:49blow air between the poly in the greenhouse so it’s not much I think it’s about

25:55it’s maybe it’s 50 Watts it’s it’s not huge but it’s something like that I have circulation fans in that Greenhouse that

26:02I don’t that I only use seasonally I don’t run them at the darkest time of the year unless I need to for some

26:08reason and um we also are also installing a boiler that will have circulation pumps that we

26:15run and when we finish the house we also have circulation pumps for the radiant

26:21floor and things like that as well um our hot water for the moment is gas

26:27but I can also turn on I can basically just turn on the electric domestic hot

26:32water tank if I want to because in the summertime for well for really six months of the year we’re over producing

26:39more solar than we need and so my problem then is I need a place to dump the electricity and so a hot water tank

26:45is great for that um once our whole home set is complete our hot water will actually come from

26:52three sources it’ll be electric domestic hot water supplemented by the boiler

26:59that goes to a heat exchanger that heats uh it’s a a touch it’s it’s called a

27:05waterless heat exchanger so it’ll use the glycol water to heat domestic hot water and then we’ll also have propane

27:12as well and it’s actually the same for our cooking once our house is finished we’ll have electric for six months of

27:18the year then we’ll use gas and a wood stove during the winter time but that’s all stuff we can discuss later but

27:25that’s kind of how our loads are broken up all right if you’re this far into it you’re probably wondering what does this

27:31whole system cost now the system wasn’t cheap and this size of

27:36a system is not needed for most people okay just flat out especially if you don’t

27:42have children I have two young kids we’re a growing family and I wanted to

27:47build this system for the zombie apocalypse basically I wanted to have enough power in perpetuity so that I

27:54could also do other things like build other buildings and send power in a way it’s my own micro grid this system is

28:02large enough you know most people could probably get away with the seven or eight kilowatt system and so basically a

28:09third of the size of the system most people would do that I’m just an overly ambitious guy I like to do things

28:15hardcore and I like to go balls to the walls so that so that that in part

28:20that’s why the system is this way you know most people you mean you could

28:26amortize the value of the system faster if you had it smaller and just burned more diesel because diesel is a lot

28:33cheaper in the short term and I’ll kind of talk we’ll go talk about the generator uh here next but uh this whole system

28:41cost 130 grand total that’s all in Canadian that’s what I’m into it so far

28:47130 Grand is all the material all the labor everything that’s what I’m into it

28:54as so you at USD it’s still probably a hundred grand or so so it’s a it’s a big

28:59system but like I said most people would be able to do with a third of this and

29:05then because even if the system was eight kilowatts total so let’s say I had a third of the solar third of the charge

29:12controllers one inverter and I had a third of the batteries that would be fine for eight months of the year and

29:18the other four months of the year at least in my climate I would be just burning diesel which actually isn’t that

29:25bad all things considered All right so the last component of this system as far

29:32as the nuts and bolts of it is the generator this is a 13 kilowatt Yanmar diesel generator and

29:39this thing is sweet it uh it I find it optimally runs at about 80

29:46percent so having it produce about 10 to 11 kilowatts is ideal

29:51as far as fuel consumption goes if you’re maxing it which you can um and sometimes I might have a reason

29:58to do that but um and I can throttle at all using that software I can decide

30:03how much power I want to send to the batteries and then how much power do I want to have sending to the load so I

30:09can do that at any given time it’s set to a default to to send

30:15um unless I want to change it and I can with just a few keystrokes on the on the software but I can uh I generally have

30:21this set so about 50 percent well not quite 50 because I run it at about

30:2880 percent efficiency or a eighty percent load and then 40 of that would go towards the

30:35batteries and then the other forty percent of that would go towards the load so it it works out to be I can have

30:40about unless I tweak it again I can have about five kilowatts going to the batteries and then five kilowatts of

30:46available to load if my wife says to me you know like say it’s been socked in for the last 30 days like it was that

30:52last period I want to do laundry okay I go into the settings of the the

30:58Schneider software and I just tweak the battery charge rate and then I’ll just

31:03put less of the battery and more to the load so I’ll just put like say uh 20 towards the batteries and then the rest

31:09of the load and then that is enough power for my wife to run the washer and dryer and all that stuff and and our

31:15washer and dryer aren’t even that they’re not efficient um they have these heat pump dryers now that’ll consume

31:20about one one and a half kilowatts this thing at Full Tilt consumes six

31:26kilowatts so it’s that’s a lot of load but we can throttle it down we can just put it on a lighter setting and it’ll

31:32it’ll consume about two or three so but this is the generator and so it goes in this and we’re still we’re still

31:39finishing all this if you followed my Vlogs at fromthefield.tv he’s kind of seen all this built throughout the

31:45summer but that’s um where the generator is housed this is the muffler

31:51that comes out and uh it’s it’s got a insulation around it so it doesn’t light

31:57the building on fire or get too hot and it’s connected to this 600 liter tidy tank which has a little fuel gauge on it

32:04and um yeah that’s that’s where I keep all the fuel so now that we’ve sorted out a

32:10lot of the efficiencies in our system uh in the fall we were running our

32:17um domestic hot water a bit longer because our old our old uh propane on

32:22demand system was just it just blew up basically and so we needed to get a new one and so we had a period it was

32:29basically all of November I was running electricity to heat our water which was brutal because it meant that we were

32:35consuming 30 to 40 kilowatt hours in a day it was insane and so I burned through about 200

32:43extra liters of diesel that I didn’t need to burn through so that was a you know call it a 400 uh mistake but you

32:50know it is what it is um but realistically now I’m tracking what we’re using

32:55and like I said earlier to get through that last really cloudy period we burned

33:00150 liters of diesel so it’s not that bad another question I get is why did we

33:07do diesel for the generator and not propane well a couple of reasons one diesel is just

33:14way more badass it’s it’s way more hardcore from resilience standpoint because you can make diesel It’s not

33:21that difficult to make biodiesel also I have a lot of Machinery on the property that runs on diesel so diesel just makes

33:29more sense it’s easier to store whereas if you want to store propane you need to

33:34have those big certified tanks and those those tanks actually the Thousand liter

33:40tanks you need to have a big truck come up to fill those up which sometimes they don’t want to come up my driveway so and

33:46I do use propane but um it uh it just makes more sense diesel we use it I can

33:52make it it’s more hardcore you know my whole off-grid system I really thought

33:58about I spent a lot of time thinking about redundancies and what is a worst case scenario so how could could we live

34:06here without electricity for one yes we could because we could we can use wood

34:11to cook on we can use it to heat our home uh because all of the even without

34:16the boiler which that’s not part of this video and we haven’t talked about it but that needs electricity to run the

34:23circulation pumps but we also have wood stoves in every building on on the property as well so we have redundancies

34:29it’s the same with the fuel is that uh okay well what if I can’t get propane

34:34well I have diesel okay well what if I don’t have diesel well I have got the sun I can

34:41heat with wood eventually I want to be able to create electricity off wood that’s a whole other Rabbit Hole of a

34:48conversation for an another time let’s talk about the seasonality of the system

34:54since I’ve had two full years with it I’ve seen what it’s like in two summers

35:01and I’ve seen what it’s like in two Winters and now I can give you a really good idea on what you can expect

35:07for solar in a cold climate especially one that gets cloudy for a period of

35:12time of winter so with this this is a I’ve actually it’s

35:17hard to say at the beginning this is a 48 volt system so it’s 20.88 in solar

35:23it’s a 48 volt system 96 kilowatt hours of battery that might help for the whole context of the whole thing but um so in

35:31the summertime like I said we produce way more energy than we can possibly use and that actually presents some problems

35:37because if you’re not using that energy and your system’s going into a float state which just means it’s just

35:45trickling up the batteries because they’re like 90 full and you’re just your your panels actually turn off

35:51you’ll have certain panels that’ll just shut off and you could be bringing in 15

35:57kilowatts of solar but you’re only bringing in four because your system’s almost full and it doesn’t want to explode so that’s what it does it

36:04creates a problem when you have electricity you can’t use in this only in an economic sense that if you’re not

36:10using that electricity and doing something with it you’re you’re shaving off time to

36:16amortize the value of your system and so let’s say a solar system like this takes

36:2210 to 20 years to amortize the value of when you split up how much the cost divided how many years

36:28um based on what you would say pay to live on the grid that’s kind of how you would roughly amortize the system if

36:34you’re not using that electricity you’re you’re thinning out your amortization period so you want to have a place to

36:40dump it so in the summertime we pump a lot of water and I’ve showed this in previous Vlogs if you look at that

36:46Homestead tour we did in the summer I talk about our whole outdoor irrigation system there’s sixteen thousand thousand

36:52liters of gravity tanks that are about a hundred feet above us here up the Mountain Ridge and I pump water directly

37:00from the well it consumes about two and a half or two to two and a half kilowatts and then I pump that water up

37:06and uh then it gravity feeds down during the day so that’s one of my dump loads

37:11in the summer is that the other is the car charging the Tesla the other is uh

37:17domestic hot water the other dump load this summer once the house is well the house probably won’t finish the fall but

37:23once the house is finished the other dump load will be running a heat pump um and then of course another dump load

37:29is doing laundry so we have a number of things that we can dump a lot of electricity into and

37:35um yeah that’s kind of how that works but so just to go back to the seasons of it all in the summertime at Peak

37:43production I’ve seen this where we have 18 hours of daylight but it’s not full sun 18 hours of

37:50daylight right because your Sun starts low in the sky it comes up high and there’s sort of a bell curve for a perfect solar day

37:56and in the summertime that can produce about 180 kilowatt hours so that means I gotta have a place to put that

38:02electricity because I only have 96 kilowatt hours of battery so I might charge the car a bit I’ll for sure be

38:09pumping water uphill my wife might do some laundry whatever we’ll run the air conditioning with the heat pump once the

38:15house is finished like that the worst so that would be your best day in the summer your worst day in the summer I’ve

38:22never really seen it produce less than 30 kilowatt hours even on the cloudiest soaked in days where it’s downpour rain

38:29all day and the clouds are really low because of the long days you still even

38:34on a cloudy day will produce some solar and definitely at least enough for your daily use

38:40in the winter times on the worst of it at the best of the worst days I actually

38:46did a short video on this December 21st this year we produced 92 kilowatt hours

38:51of solar so at the shortest day of the year if it was perfectly sunny I could still get 92 kilowatt hours of power the

38:59worst of the worst days was I’ve had a number of them this winter but the lowest I’ve ever seen the system produce

39:06in a day is 1.8 kilowatt hours so if you think about the worst of the worst or

39:12the best of the best that’s a hundred x uh difference between one of the other so that’s quite significant but that’s

39:19kind of what it looks like and everything in between is kind of just fine there’s you know you’ll have some

39:25variation but like I said in the winter in the darkest time it’s that one month

39:31period two weeks on the shoulder and two weeks on both shoulders of the winter the solstice is the worst time for solar

39:38and that’s what I’m going to be running Diesel and um yeah that’s kind of what it looks

39:44like in the seasons but again there’s really only one month of the year that I need to run that generator so one of the things I wanted to correct the record on

39:50because I I don’t want to delete the video because it’s a good video but I did a video and I’ll I’ll it’ll pop up

39:57here um last summer where I toured the system I set a couple things that were incorrect one is I said we only burned

40:04100 liters of diesel in the previous winter I was I was off there we burnt about 200

40:10liters we burnt less diesel last year than we did this winter because we have more infrastructure this winter and

40:16we’re we’re consuming more last winter we had less stuff finished this building wasn’t finished until halfway through

40:22the winter or actually most of the way through the winter and the other thing I said was just regarding our batteries I

40:27called them lithium iron sulfate they’re lithium their lithium iron phosphate

40:33that’s what these batteries are made of so that’s what I want to say to correct the record okay now I want to discuss

40:38the most common questions I get and I want to address them because there’s a number of these questions that come up

40:45um people have kind of wild ideas and you know there’s just the reality of

40:51being a YouTuber is everybody’s an expert and uh at least from my perspective in the comment section

40:57everybody’s an expert and very few people actually do this stuff and so I kind of troll people a little bit with

41:02it it’s like oh is that what you did with your system or or are you doing that with your system people always have all these ideas and things you can do

41:08and they just don’t know anything because they don’t run a system they don’t you have to be in something to

41:14really fully understand it in my opinion you have to have it’s like they say to be a Bonafide expert on something you got to put in 10 000 hours and most

41:21people don’t have any practical knowledge they just have YouTube video other YouTube videos they saw so one of

41:27these really common questions I get is why don’t I have these panel rigs

41:33follow the Sun well it’s really an easy answer it’s expensive to do that these are Big Rigs

41:40they’re about 20 I think they’re 28 feet across and like uh maybe 14 feet high on the panel side

41:48and then you’ve got all this weight here also I get snow so imagine putting this thing on a sort

41:55of gyroscoping rig is that the proper term gyroscoping I don’t know but but

42:01basically if you had this follow the Sun it’s quite a bit of engineering I have three of them okay so it’s probably to

42:08do something like that I would imagine wouldn’t be any less than ten to twenty thousand dollars per rig and some

42:13armchair quarterback out there is gonna say oh I can do it for this and it’s like okay maybe you could but I can’t so I’d have to hire somebody to do it

42:20um what you have to think about with all these things I’m going to mention is you have to think about what’s the cost to

42:26do it and then what’s the cost just to burn more diesel so let’s say I made

42:31these track the Sun and let’s say by some miracle I could make all of these track the sun and it would it would cost

42:40a total of 50 Grand let’s just say it’s 50 Grand how many actual kilowatt hours is that

42:46going to get me because during the main season for the other 10 months of the

42:51year that’s of no value because for the other 10 months of the year I’m not I don’t need to get more electricity I’ve

42:57got enough uh it might be more valuable if you had one of these Rigs and and uh you know

43:04you had less expense that way and then you had it track all season so thereby you’re getting kilowatt hours all year

43:11it might be worth it but it’s all about context and so for my context it just doesn’t make any sense it’s way too much

43:18upfront money it’s a whole bunch of engineering it also would mean that during the winter not only do I have to

43:24scrape off the panels but I got to go behind it and scrape the snow off the track for that thing to move so you know

43:30we get wind up here too it’s just it’s just not practical to do that so that’s the main reason why I wouldn’t do that

43:36and again you have to think about well how much would it cost us to burn a bit of extra diesel for that one month period that I actually needed in

43:44so the other one a lot of smarty pants comment on which I find hilarious and just kind of shows how people don’t know

43:50anything about electricity or off grid is people see me scraping these panels off and they say well why don’t you have one

43:57of those electrical things that just melts it it’s like dude do you know how much how inefficient heat from

44:03electricity is it’s ridiculously inefficient and at a time that I need all the kilowatt hours that I can

44:10sending electricity when I have very little on the batteries to melt snow on

44:15panels is is just a non-starter like it just it doesn’t make any economic sense and again you have to ask yourself the

44:21question for when do I need that what does it cost to do that infrastructure and then what does it cost in kilowatt

44:27hours if I didn’t do it so it’s just one of those things it just doesn’t make any economic sense whatsoever and I’m sure

44:35there’s a context somewhere for somebody that it might make sense and if that’s your case all the power to you but it

44:40doesn’t make sense for me the other one is why don’t you get some wind power well

44:46if you can see those I do have wind power technically those are two 400 watt

44:51by 12 volt windmills and they’re absolutely useless

44:57you can see right now they’re not moving and that’s about 90 of the time they’re not moving

45:02wind in my opinion for the most part is a total nothing Burger

45:08um again just at the same thinking as the last one what’s the cost to do it

45:13what maintenance challenges does it bring what potential hazards are there you know what are the weak links and

45:20then base that cost on burning a little bit more diesel and it’s most likely not worth it so if I had wind

45:26maybe say at least 50 percent of the time it might be worth it there might be

45:32a case for that but that’s not my situation these are about 50 I think

45:37they’re about 60 feet off the ground so they’re fairly High yeah they could probably be higher but um they don’t

45:44move a lot and they were from the original system here and they’re just they’re just a waste of time the general

45:50thinking when you’re off grid if if solar is the primary base of your system now if you’re talking Micro Hydro and

45:57stuff like that that’s a whole other animal I don’t have Micro Hydro because it’s not I’m on a mountain so if I was at the bottom of the mountain I might be

46:03able to have Micro Hydro but I’m on the top and so um the basic thing comes down to is yeah

46:10you might as well just add more solar if you because solar is actually as far as

46:16these three things that I’ve shown you generator solar and wind

46:22um solar is well even comparing it to Micro Hydro is is really Superior in a lot of ways there’s no moving Parts

46:28solar believe it or not is very available solar also the only problem solar gives

46:35you in the winter is that you got to scrape off the sun uh scrape off the snow off the panels but you know Micro

46:40Hydro in the winter isn’t that easy either especially if it’s a small system it can freeze up on you and I’ve seen

46:45dozens of Micro Hydro systems and that’s been the case for people in cold climates and so you know another one

46:51people say is oh Curtis why don’t you pump water uphill and then use that

46:57Micro Hydro power to bring it down it’s like well dude the only time I need that

47:02power is in the winter and what do you see all around me Frozen stuff so so

47:09pumping water uphill in the winter doesn’t make any sense I mean if I didn’t freeze

47:16and I lived in a part of the world that didn’t freeze and I had low Sun it might it might make sense to pump water uphill

47:23on your sunny days and then drag it down on the winter days but I’ve heard a

47:29general energy conversion for that is about you get about half what you put in so if you spend 10 kilowatt hours to

47:35pump it uphill you’ll get about five going down and there might be a case for that right but but it’s just not

47:42practical in my context to do that it’s just it doesn’t make any sense so

47:47the the thing with all of these that you have to look at when you want to say well what about this or what about that

47:53you basically have to amortize that from the cost of just burning a bit of

47:58extra Diesel and just up until a week ago and it was part of the my inspiration to do this video is I was

48:05really considering adding another rig because I have the flexibility in my system to add another rig actually more

48:11than another rig technically these aren’t maxed out to what those charge controllers could add I could add another 24 panels to my system if I

48:17wanted to but that’s going to cost me because I’ll have to have another place to have the panels mounted there’s not

48:24really it’s not really going to work on my roof of my buildings because the roofs actually slope to the north

48:29I could potentially put it on the face I’ve looked at some different options it just creates it’s just more wire running

48:35around it creates a bit of a Rat’s Nest with the wire and it’s just inefficient that way but uh you know it’s it would

48:42cost around at the very bare minimum 10 grand if I did a lot of the work myself and sourced the materials myself I could

48:50maybe do it about 10 grand I’m not that good of an electrician to do all the final stuff but that’s okay I could I

48:55could do most of the work have somebody else do it so what I have to look at is okay if

49:00it’s 10 if it’s ten thousand dollar investment that investment’s only going to be used at the darkest time of the

49:05year and I have to factor that in well what does it cost just to burn a bit of extra

49:10diesel for that month and so like I said earlier in this video it costs about 150 to get me through the

49:16darkest time of the year in diesel or 100 no 150 liters so let’s say it’s about 300 bucks

49:23300 bucks divided by 10 000 is a lot of years to amortize so it just doesn’t it

49:29just doesn’t make sense for the most part so that’s basically it you guys I hope I

49:34nailed everything in there if I have missed anything let me know your thoughts shoot me your
