Looking into battery storage for home use again. My goal would be to have enough solar to power the house charge car plus batteries for nighttime use. I know solar panels have gone down dramatically in price but wasn’t sure exactly what the data on batteries was. Now I see 10x this decade, with $100 per kwh already achieved for a large installation. Today this is attractive. In five years batteries in homes should be a no-brainer. Should also make electric cars a no-brainer over gas. Pretty much the same for large scale grid applications. This could, like most modern technologies, happen quickly.
