The city has a new calculator:

I'm a bit confused though. It says 17 panels is optimal, generating 6245kWh/year. My quick math shows that is about right for generation using factors I've used before, so that's fine.

What I don't understand is the claimed monthly savings is $108. I use ~700kWh per month at a cost of ~$50. They claim I can generate 6245kWh at 6c/kWh divided by 12 months, which gives me ~$31 in electricity savings. How do they get $108?
