Same here. So far solar has not been practical for us, even with our huge electric bills. I would love for someone to come up with a simple, cheaper, working system.
It’ll be feasible if there’s a way to capture and store both the electricity and heat efficiently. Typically, you don’t need a lot of excess heat on bright, sunny days, but you might at night.
A 12Kw system would be ideal for one or two homes, if excess generation can be stored during the day for use at night. Offgrid rural users might be able do some kind of pumped storage, if acreage and topography allow, to supplement a moderate battery/inverter system. Less rural users would need a large enough battery array to handle the nighttime load. Suburban users could just couple to the grid and make money during the day when rates are highest and buy back at night when rates are lower.
