In the US it's typically about a quarter.
- rjdj377dhabsn 11mo agoIt shouldn't be that expensive. I had 10x 500w installed and wired on my 7-8 meter high roof in 1/2 day. I only paid $50 where I ljve, but even with 10x higher labor costs in the US, it should be under $1000.
- kragen 11mo agoIt shouldn't be, I agree. And eventually it won't be. But SEIA's report https://www.seia.org/research-resources/solar-market-insight-report-q2-2024 https://www.seia.org/research-resources/solar-market-insight... said that, in Q1 of 02024, utility-scale fixed-tilt installations in the USA averaged 98¢ per peak watt, of which 40¢ was the PV modules; and residential installations averaged 325¢ per peak watt, of which 20¢ was the PV modules, which is an atypically low share, historically speaking. Where do you live?
- pfdietz 11mo agoI'm surprised at the 40¢ figure for utility scale. Are you sure that didn't include the mounting hardware? Utility-scale PV is typically with 1-axis trackers. Another possibility would be that utility scale solar optimizes to a much large disparity between DC rating and AC rating than does domestic rooftop PV.
- kragen 11mo agoI was surprised at it too, but remember that the US basically doesn't allow Chinese solar panels to be imported.
- pfdietz 11mo agoWait, so those were not US residential cost figures you quoted? Because I don't see how they'd allow Chinese imports for only residential installation.
- kragen 11mo agoThose were also US, yes. I don't know why they were so much cheaper. Possibilities include: - Maybe the SEIA is wrong. - Maybe utility-scale projects sign contracts to buy PV modules further in advance. The prices were falling rapidly. - Maybe residential installers were buying low-cost panels with lower efficiency or with no warranty.
