Even though we’re still two weeks from the end of the year, I decided to add up the 2021 numbers for our home solar production vs. electricity costs so far. As you’ll see below, our rooftop solar system offset over 95% of our electricity for home usage AND electric vehicle charging!
It’s worth noting that we added a heat pump to our HVAC system this summer, so there was some additional home electricity usage for heating, while also saving us a bit on home cooling in late summer. Also, we have net metering through our utility, where excess kWh production is credited into future months. And finally, we passed up a discount and paid a registration fee (around $300 combined) when installing our solar panels, to retain the ability to sell our SREC’s (Solar Renewable Energy Credits), a choice that has more than paid for itself in less than three years.
