Since snow accumulation can limit or block solar energy production, I decided to adapt a telescoping “roof rake” for snow removal from our solar panels.
While this solution isn’t practical for most roofs adorned with solar panels, the solar array on our ranch style home with a 5/12 pitch roof is easily accessible from our deck.
Here’s a video I posted of removing snow from our panels for the second time this winter:
Once you have most of the snow off the panels, their black color absorbs more heat from the sun and helps melt away remaining snow, letting the sun shine in!
Today, I removed a thin layer of snow to further expose an ice layer that was melted by the sun. After 30 minutes, most of the panels had far less ice.
10 or 15 minutes of work doubled our solar energy production. Before and after photos:
One final thought…
Did you know enough solar energy reaches Earth every hour to fill all the world’s energy needs for a full year?
So let’s start leaving fossil fuels in the ground where they belong… with the fossils!
