- walrus01 9y agoYes, with complete overcast even a very large PV array such as quantity 80, 370W high-efficiency 72-cell panels, will not produce more than 3 to 5kW. In bright sun it'll be well above 23kW. Under STC (standard test conditions) that's a 29.6kWh array... what you should care about is your kWh/month produced.
