Two array's, total 6.81 kW rated nameplate capacity. 952 kWh for the month of June.
Timing of purchasing combined with various incentives affect everyones payback on money invested, but my arrays went live on 12/17/12 and I am 54.936% repaid. I need 89 more kWh to hit 55%. If the cost of buying electricity never goes up, I am still on track for about a 10.5 year payback, weather dependent of course. Solar has been the very best investment I have ever made.
