Happy New Year! In 2015, my solar system produced 8545 kWh (That’s equal to a cool tax free $1281.75 – to answer a question I get a lot from people). In most months the production was more than expected:

Considering that producing power with coal takes 1lb/kWh and producing power using natural gas uses 1cu ft/kWh, the system offset the use of 8500 pounds of coal or 85000 cubic ft. of natural gas (85000 cubic ft = 4 times the volume of my house)! In one year. On top of that the system gave me annual returns of 10.6% on the money invested, not including some tax benefits from selling power to Dominion with their solar purchase program. There is still time left to join the program – they have 25kW left for residential customers.
