I am waiting more for the longevity of the roof than the panels. I’m not too keen on putting a lot of penetrations on an aging roof. The $30k number was based on a 10kW system (we’re limited based on a multiple of actual usage). But what you said makes sense and I should ask around for other quotes. But even at half that cost, I’m still looking at a 12-15 year simple payback. On a 20-25 year system, that puts the IRR at ~5%. My thinking is I’d rather have the liquidity of putting that money in the stock market.

And don’t forget about inflation when doing your ROI and invest returns calculation. US electricity prices averaged 16.04c/kWh March 2023 to March 2024, but 15.50c/kWh March 2022 to March 2023. https://www.eia.gov/electricity/monthly/epm_table_grapher.php?t=table_5_03 https://www.eia.gov/electricity/monthly/epm_table_grapher.ph... As to liquidity, the stock market may be a better long term investment but it’s quite risky even over surprisingly long periods.
