Proof that Solar Works in Kentucky

By Dan Hoffman, President of RegEN Solar (KySEA member)

Even after two years of running a solar panel installation business, I'm still surprised when I hear people say that solar can't work in Kentucky because it's too cloudy.

Regenen Solar Graphic

I had a few minutes this past weekend and put together this this graphic that shows the daily electric output of a solar panel system we installed in Frankfort, KY in March of this year along with the weather from each day. The system is doing great and producing as expected averaging about 20 kWh per day. As anyone who looks at it can see, even on rainy and cloudy days the solar panels are still producing electricity. Usually about 20% of system capacity. Additionally, this customer's roof angle is less than the ideal 38 degrees to the horizontal so he'll be averaging more over the coming summer months.
