Are Solar Roofs Efficient During Winter?

The winter season is upon us. “Does solar energy work during the winter?” is a common question asked by people interested in green resources.  We have the answer:

solar roofs






Performance of solar panels is actually increased during the winter season. They work better in colder temperatures than in hotter ones. Despite this, they still produce less overall energy due to the decrease in hours of sunlight.

In the cold season there is a top average of about 9 hours of sunlight per day. In the summer this top average increases to about 14 hours of sunlight per day. Those 5 hours make a bigger difference than the efficiency gained from cold temperatures. Heavy clouds can block absorption of solar rays, but this applies in the summer as well as winter. All excess energy during the summer months is stored in batteries to make up for the loss during winter months.

Here at Alliance Roofing, we offer solar roof installation. So for more information call (860) 633-7243.
