Balanced Numbers

This 7,650-watt system produces about 7,650 kilowatt-hours (kWh) of electricity a year. The numbers don’t always equate like that. In fact, most panels produce kWh by a factor of more than 1 compared to system watts. But production is affected by azimuth, shade, etc. and it just so happened that in this case, watts and kWh are about the same.
