It actually makes financial sense to purchase solar panels for many, many households -- they just don't realize it.
(If anyone saw my previous message, I just had a brain fart and confused SCTY with SPWR)
Or maybe they realize it and are fine with just paying less for electricity. You are arguing saving $50 a month for nothing or coming up with $20K to save $100/mo.
I meant purchase/get for free.
Anyway, that $20K is financed with a very low rate loan, and much of it is accounted for via income tax credits.
