Solar Update – September 2017

solar-panels

It’s time for another usual event: getting excited over receiving my utility bill. This year was my first full summer with the panels and I am pleased to report that they are performing as expected. I’ve had negative balances consistently since May which means not only do I not have to pay for the electricity, I’m producing more than I am using and thus I am accumulating credits for the colder shorter winter days. While our electricity usage spikes in the winter due to the continuous use of the heating system and we will not have enough credits to cover the entire winter, we are still likely to cover at least one full month of electricity with the credits we have accumulated since spring.

Actual electricity bill for August 2017

If you’re curious what a full year of panel use looks like financially, take a look at the image below. For context, my house is 3,100 square feet and all of my appliances including clothes dryer and stove are electric. We also have central AC and the heating system is powered by electricity. We have 2 refrigerators and well water which uses an electric pump. This is not a typo. Between August 2016 and September 2017, we paid less than $500 in electric costs. That’s not even 2 months of cable in my house. How much would you save if you were powered by the sun?
