I'm making great progress on installing roof top solar and found that I can actually include a few more panels in the plan. I'm trying to guestimate how much electricity the system will generate to see if I should buy a few more. Can someone with more knowledge than me affirm my understanding and approach?
Phoenix AZ Average Peak Sun Hours: 6.57
Panels: 30
Pannel Wattage: 440W
Panel placement: 15 on pitched roof facing east. 15 on pitched roof facing west
So I use the following equation to guestimate production: ((6.57*440*(15+15)*0.5)/1000 = 43.36Kwh
I divide everything by half because half the pannels face west, half the pannels face east......Generally speaking, is this math sound?
