I think you're well meaning but you're listening to cherry picked "expert" data intended to portray solar power in a rose colored world. Few people have enough land to cover with gray panels just for themselves; those few people who have cell fields will have to clean the surface film off their panels every few weeks or the output will be cut to 50% or less. Even those few who can power their routine needs will NOT produce enough extra power to supply any serious job producing industrial plants. Any battery storage buildings will have to be huge if they are to help power anything but their owner AND the batteries themselves will need some temperature moderation system. AND the batteries will require frequent technical attention (and replacement). AND assembling the batteries themselves is both expensive and injurious to the world's ecosystem. AND the cell fields must be constantly mowed around or tall weeds will soon provide them a shade cover. AND the cells also have a limited lifespan. Etc.
That is the happy side of the story isn't it. BUT, the happy experts never mention that actually "saving money" and "power independence" depends on a constant flow of government money; stop the various tax subsidies to individuals and power companies and the cash figures will immediately reverse.This is a real thing that real people are actually doing and actually saving money with or achieving grid independence with, not just the raving greenies.
Yeah. Still. ???There are gotchas that you have to think about, like buying from an established and stable vendor so your warranty is worth a damn in case something goes wrong, things like that, but still.
Maybe it will all work great together. IF you have enough unused land to base it on. And IF no storms destroy it. And IF you have a great place to store your battery system. And IF your Prius itself doesn't take a costly dump on you.The worse the electricity prices get as they phase out coal and gas, the faster your ROI will happen.
IF politicians wave their foolish hands in the air and rule out gas, coal and nuclear plants before a serious substitute power system is in place there will be no tomorrow. Sun and wind sure won't do the job, not for any life style we would recognise ... or desire. I've believed small nuke plants are the power grid future since the mid 1950s; still do.
