I bought my panels outright about 6-7 yrs ago, this leasing thing wasn't an option back then. I have a system rated at 3.45KW (30 panels) and on average produces about 25-30% of my electrical
needs. Size of panels and efficiency have increased so # of panels is meaningless. I produce up to 55-60% of my needs mid-summer and 5-8% during late Nov- early Jan. I also actively clear off
the snow, you could loose days of production if you wait for snow to melt off.
I have perfect southerly exposure and little to no tree shade impact.
