Ah, I see what you mean. I was thinking it was dependent on sun exposure, but the panels each have their own wattage rating. So an 8kW system is an 8kW system independent of sun. Probably something I should've looked more closely at at the time of purchase. I was more focused on the fact that it would essentially lock in the current rate we were paying to Eversource based on the expected production over the life of the system.
