I believe I read that the rule is that you are supposed to get 80% of the charge from your panels. So no, one panel would not do it.

When I looked into it, the installer said roughly a 6-foot by 20-foot array. That was a nominal 2kW array, but of course you lop of some percentage for inefficiencies downstream of the panel and for less than perfect sun, et cetera, et cetera. On this my memory is less clear, but I think he said you would expect to get 1.3-1.5kW out of it for the peak sun hours (peak sun hours is an official thing - the periods of the day when you get 1kW/m^2 I think, and you can look it up for your lattitude).

We have a solar/battery installer who was supposed to come last week, but cancelled because of the snowstorm. Rescheduled for Thursday.
