solar panel on snowy days

The winter season and accompanying snow will reduce the production of solar panels—there’s no denying that. While that shouldn’t be surprising, there are still plenty of misconceptions about solar panel operation and snow.


A snowy winter day is not ideal for three out of the four major factors that affect solar panel performance:

Length of day: Winter days are the shortest of the year

The angle of sunlight relative to the panel: Your panels receive the least direct sunshine in the winter

Sunlight intensity: Sunlight is often diminished by cloud and snow cover in the winter

Temperature: Panel production improves in colder temperatures


All these factors result in a significant reduction of energy during the winter months. A rough rule of thumb is that wintertime production is about one-third of summertime production while spring and fall production is about two-thirds that of summertime production.

Safe Solutions For Solar Panel Snow Removal

1) Wait it out

The most common method for how to get the snow off of solar panels is generally to just wait. The snow might melt, blow away, or slide off on its own.

2) Use a roof rake

One of the most popular ways for homeowners to remove snow from solar panels is by using a roof rake. This method, while time and work-intensive, is the most effective snow removal method.

3) Clean your solar panels year-round

Clear studies are proving that dirt, dust, and pollen affect solar panel power generation. The roof Brum Snow & Wash Kit can help you keep your solar panels in peak condition year-round, in winter or summer.

4) Reorient your array

If a storm is coming and you have some ability to adjust the solar panels (angle, orientation), or if you’re thinking ahead during the initial installation, it’s possible to mitigate some risk of snow accumulation. A southward-facing array will get more sun during the winter months, which helps accelerate melt-off as the panels soak up more warmth. A steeper angle would also make it harder for the snow to build up and encourage it to slide off before there’s too much.

5) Hire a professional

It would take a bit of an investment, but should the situation grow serious, there are snow removal services that will know how to remove snow from solar panels on your roof. Trust professionals to have the right snow removal tools to handle it without damaging the panels.
