Our first electric bill since turning on our solar system is here and it’s even better than we expected! The pre-installation assessment estimated that we’d generate about 40% of our power, but we’re actually generating about two-thirds!
Between March 18 and April 16, we used 126 kWh, and generated 80 kWh. So, in 1 month, we’ve only purchased 46 kWh of power from the grid!
Our provider (CL&P) charges $.122170 per kWh, resulting in $5.62 of generation charges for the month. Our actual bill was $24.25 because of $18.63 in delivery and other charges, but there’s no way around that (we tried).
During the same period last year, we bought 410 kWH, resulting in a bill of $78.89. This year, we’re using less than 1/3 of that. So, in addition to generating the majority of our power, the solar panels have helped us to become more mindful of our consumption :)
We’ve become slightly neurotic about our electricity usage. We bought a Kill A Watt meter and have been testing every electrical device in our house, seeking out secret offenders. We’ve had quite a few surprises; I’ll post on that later.
Happy Earth Day!
