Then you have to subtract for cloudy conditions, and to a lesser extent things like sand storms, local smog, etc. Plus time eventually maintenance time. Already factored in.. That's what the battery is for at night and vary, vary rarely during the daytime. Even if it's cloudy the array can still produce some power, it doesn't drop to zero. Maintenance down time since 2000 ZERO. I did wash some of the panels many years ago to do a test on output and it made only a 1 % improvement in output. Did not have to shut down the system to do that. Each string is monitored 24/7/365. You have to design the system to where you live. A very simple process. I have a very small wind turbine that I usually operate in the wintertime to complement the PV's if I'm up there.. It's surprising how much power it generates when we have a multiday storm up there. If you do it correctly it balances the system power winter thru summer. Eric
