what’s the source for the $25/kWh claim? that’s about 100x more than I was expecting.

Yeah the article doesn’t actually say that at all. That appears to be pulled straight out of OP’s ass.

However, if that’s the installed cost, and per kW, then that’s insanely cheap. Solar where I am is about $2500 per kW capacity installed. $25 per kW would be dirt cheap.
