Big question
guaranteed success would mean designed like an off grid stick house
Enough solar to power all daily use while recharging batteries enough batteries to supply all power for multiple days of bad weather
A low power energy. Efficient. Fridge
i'm guessing 700w might do it in the summer time, but for winter i would need 1000w on the roof to get the same output charge into the batteries
my 321 watts is a big help, in the dead of winter it was meeting about 42% of daily needs
right now it is meeting almost 75% (with clear skies)
during the height of summer it might meet almost all except for A/C needs
at this point thats all i'm hoping for, off setting some of the power costs, maybe i can a get few more panels later this yr
