Realistic off grid system?
I have a family member who is considering buying a piece of property and building a house, however they will not be able to get grid power there. I am trying to make sure they have the full picture of off grid living and not having grid power. Its a bit of a red flag to me, someone who is thinking of going off grid just because they cant get grid power, not because they want to. I lived off grid for 10 years, but am now grid tied with solar. So I feel that I know what its like and am telling them to proceed with caution and trying to make sure they are fully informed about what they are getting into. I may help them design and build the system if they go thru with it. I just want a reality check on a few things. Like I said I lived off grid for years and have done some small simple systems, but I havnt really done any larger scale off grid homes. They talked to a solar contractor who is saying they can use mini splits for heating and that they should be able to only need about 10 gallons of generator propane per year. This is central NY state. This seems very unrealistic and throws up some red flags on this contractor. Am I off base? Sure we would be talking a large array, probably 10-16 KW, but I am skeptical of heating with mini splits off grid during those short dark winter days. Sure sometimes, but I dont think you can count on it. Thoughts?
