4 hours a day seems light…[/quote]Usually, I’ve seen solar system talked in term of kWh (# of panels x # watt the panel produced per hour). I think that’s a better way to compare system wrt cost. Since every house is different, it would be hard to compare. It better to compare theoretical max production vs actual production, since every house is different.[/quote]
OK…I’m seeing how it fits together.
40 panels x 260 watts per panel = 10,400 watts which is 10.4 kw system.
I think they are being conservative figuring 4 hours of output a day as a neighbor with the same roof orientation told me he gets about 5.
