@pluralistic A few years ago I asked for a quote from the local big-name company who came in with a $43k bid on a 20 year financing plan. The panels, hardware, and inverters worked out to $17k market price. $43k was also exactly how much electricity it was projected to generate over 20 years at current rates. I think their bidding process was to subtract the hardware cost from the estimate and write down the balance as "installation and project management costs."
