Our system have been running 26 months and we just hit the 40 MWh mark.
Since our power cost about .10 Kwh that is $4,000 Solar power made.
We are very pleased with the system performance. We are now able to cover all our power usage and this also covered driving our Chevy Volt 38,484 EV miles.
Hot water is the only thing we have on natural gas. Everything else runs on solar. Our water bill is higher than our power bill and natural gas bill combined. Power bill and natural gas bill combined is under $30 a month.
Last month gas and power bill together was $26.25 my water only bill $40.25.
We have septic tank so this is for water only.
The bottom array was added later that is why those numbers are lower.
