Orange County public schools all have these, but does it make any financial sense given the huge investment and the fact that the panels have less than 30 years of lifespan?
You can basically rationalise against any investment, because there is no limit to your imagined opportunity. Just keep the cash always so you always have the opportunity!
The "inflation" bill that further supports the fossil fuel industry about to be passed will certainly make it more appealing in the U.S. at the expense on developing countries that get more sun. Solar is great, but subsidizing installs in Prudhoe Bay don't make a lot of sense atm.
