In our area its THE AMISH that are really getting into Solar. Many have 4000 to 6000 watt rooftop or fixed ground mount arrays elevated at 47 degrees facing south of course.
Ifffffffffff your local electricity utility allows grid tie you dont need battery energy storage so much plus inverters BUT some now use net metering so your savings is less grrrrrrrrrrrrrrrr
Economics and payback are NOT the ONLY reason why I may or may not install solar on my next home.......Its NOT for everyone I'm more into TOTAL energy savings and self sustaining and will consider Super Insulation,,,,,,,,,,Perhaps partial in ground construction,,,,,,,,,,,Perhaps PASSIVE solar heating,,,,,,,,,,Perhaps solar hot water heating,,,,,,,,,,,Perhapos some geo thermal
Local utility charges and availability makes a big difference as to an investment in insulation or geo thermal or solar or wind. Just because some like it and some don't is of no consequence to me ITS A PERSONS OWN PERSONAL CHOICE which may or may not prove economically the best........
John T An engineer and believer in alternate energy and I do NOT like to limit my options to only one thing, I consider solar and super insulation and wind and geo thermal and all else lol
