Solar Production in 2022

2022 was the fifth year for our rooftop solar system and at 7,569 kWh was the most productive year yet. That’s likely because we added a 4th string of panels to array #2 in October, raising our charging capacity from 6.4 to 7.4 kW. Definitely made a difference in those last 3 months of the year.

We used 3,126 kWh here and sent the excess 4,443 kWh to the grid, saving us a total of $1,240. Electricity costs rose sharply this fall but our existing contract with our supplier didn’t expire until November, but then it rose about 60%, so our rate of savings will increase this year. We’ve earned back $5,618 or 35% of the original investment.

Best month of production in 2022 was July, at 829 kWh, with May a close second. November produced a surprising 600 kWh, a combination of the additional panels plus a lot of sun.

We should see our biggest year yet in 2023 with the extra 1000 kW of charging power added by the new string.
