On the average monthly savings side, it's anyone's guess - I can't tell if they are calculating off of the RRO option, or taking into account solar club? it seems to be somewhere in between the two.
This was a terrible effort by the city, the solar potential map is cool, and then they mailed it in, in the calculations.

The problem is there are no details on the calculation. They make assumptions but they arent apparent and also as you mentioned the install cost is a wide estimate at best, and I dont think it takes into account the $5k federal grant which would change the payback period
