Maybe there’s something to this solar power thing, with it’s renewable-ness and positive ROIs. Major U.S. retailers, who understand narrow profit margins and keeping expenses down better than anyone, have installed hundreds of megawatts of PV panels. See who’s converting to sun power.
Slapping a solar panel on the roof sounds so alluring. You can produce your own energy, slice your carbon footprint in a big way and not have to fret so much about vacillating energy costs. You’re home free.
Except that solar panels are far from free. While the cost of solar photovoltaics has come down considerable, a solar rooftop array remains in a rarifed price household category, right up there with cars. It will run in the ballpark of $15,ooo-$20,000, maybe more, even with home energy tax credits.
