Our 24 panel system generates about 5 kW maximum, and as much as 35 kWh on the best of days. This has really tamed our summer AC bill, and winter heat pump heating bills, when it is not covered with snow.
The solar panels may sometimes suddenly drop snow onto our driveway. Perhaps in hindsight, we should have installed the panels on another portion of the roof so we wouldn’t have to clear the driveway twice. We may eventually find some way to prevent it from sliding all at once. The bottom line is that we sometimes get very little solar production in February.
