Mine is rooftop and was installed professionally. One days work for 2 roofers and 1 electrician, not exactly a huge labour cost, surely. Raw material cost is about 6k (inverter, panels, battery) so at 9k that's 3k for one days install. Not a bad profit, so why is 30k reasonable cost in the US?
- AstralStorm 4y agoYou probably skipped the certification that allows you to sell power back to the grid... But maybe not.
- tails4e 4y agoMine was done by a certified electrician, all above board, and I can sell it back to the grid.
- SECProto 4y agoI'm in Canada not the US. I had relatives get rooftop solar, bigger system but not significantly (I think around 10kW). It took them 2 or 3 days to do the install for a crew of ~6 (over 2 trips), plus another 3 visits by the contractor and a utilities inspector - once beforehand, once following mounting system and wiring install, and a third time following completion before it could be connected. Don't know material cost, but the full system was somewhere around $40k (I guess that's Canadian $, so subtract a few $ to get USD). This was with an asphalt shingle roof, so it'd be more for metal or tile. You could ask your BIL if the estimates he received had any breakdown. Edit: there may have been an electric panel or service upgrade rolled into my relatives cost
