I would encourage anyone interested in this to go plug example size of small pv systems into this calculator for your location: https://pvwatts.nrel.gov/ https://pvwatts.nrel.gov/ You can use a round number like 1000W, which would be the same as four fairly cheap 250W 60 cell polycrystalline cell pv panels.
