location and climate , time of year occupied ?
Don's estimates trend toward off grid solar home type use in far northern climate
our residential fridge is our largest power use ,followed by lighting
where we are
if we had a lp fridge the 300+ watts
on the roof would.cover most of our
use
the mw & coffee maker would still need the generator
not enough solar to recover the deep power drain from those items
to go without generator recharge using our residential fridge we need about 600watts of solar and eight batteries
I have the extra four batteries waiting for me to build the slide for them,
I don't have the extra solar
your power needs will be different
