Yes, you need to do some of the legwork here.
Learn how to find out how to do an energy budget, measure electrical usage for each load device, in AH per minute or hour. Then estimate how long per day they'll be in use, come up with kWatt hours total per day.
> Whether using solar is efficient or not doesn't really seem to be the question.
"Efficiency" is not the issue, except in the sense of "how many AH per day gets generated in average weather per square meter"
> I have been on a rural electric coop for 25 years and having had to spend $9000 just to bring power in and then having to pay .14 kWh plus a $52 monthly service charge and having been forced to use propane for cooking and heating at rates of over $2.00 per gallon I consider being totally responsible for producing my own electricity priceless.
> If I took the time to figure out how much I had spent to be tied to the grid I know any amount I spend now is minor.
No, renewable sources costs **lots** more than grid power, even amortized over say twenty years.
> Why would this request seem outrageous? I have seen some very fancy semi's out there that run full size appliances and air conditioning systems using only inverters and batteries.
Really? How many? You talking like a 40' mobile home type trailer, eighteen wheeler sized?
Yes, that would be about what it takes.
Just the "air conditioner from batteries" part is a **huge** challenge, very expensive, like 5x the other stuff you're talking about.
A generator will need to run nearly as long as the A/C does, all the huge battery bank does is let you not have to run them both at the same time.
With **very** good weather, **lots** of solar panels will get you 3-4 hours of A/C maximum.
Less than optimal weather, you'd need an 8*40' trailer.
Start off with a big bank, charged by a good genny powered system, plus a little solar for "the long tail" getting the bank to 100%. Or if money is really no object, budget $15,000 or so for a decent LFP bank.
Make sure all appliances are as efficient as possible, using propane and 12V DC native as much as possible.
Then add maximum solar you have room for on the roof, will likely cut down on genny runtime by a few hours a day.
