From June till September last year(pre solar) my energy bill was near 200. My financing is about 70 dollars a month for the next 20 years... I'm expecting my solar production to cover probably 70% of my bill. Since I'm paying financing plus utility hookup(mandatory $10), plus what ever I use after solar; I will likely not recoup my investment. Imho, it's more feelgood and a hedge against future energy price increases.

I have also noticed that I pay attention more to my consumption. I've debated on buying an energy consumption device like sense, but it seems like a toy...
