How Snow Affects Your Solar Power System


It’s hard to deny the rising trend of extreme weather patterns in our world. The top 10 warmest years on record worldwide have all occurred since 1998, and the U.S. has experienced an increase in heavy precipitation and extreme temperatures in recent years.

Intense winter storms more likely than ever, we wanted to provide some tips about snow and your solar system, so you can focus on more important things this season, like staying warm and safe during inclement weather.

Don’t worry about shoveling snow off your solar panels. Their dark surface will gather sun and actually help melt the snow, causing it to slide off the system’s glass surface.  Raking off snow could harm the panels by scratching them or worse, harm you, were you to slip and fall or be caught under snow and ice falling from your roof.

Don’t fret about solar energy production either. While accumulated snowfall can cover panels and temporarily halt production – and in general, your system won’t produce as much solar energy during the winter months due to shorter days – your system is designed with your annual energy consumption in mind, and thanks to net metering any credit you accrued during sunny, overproductive months is going to come in handy now.

You may actually see an increase in production after the snow clears from your system. Solar panels perform better on cold sunny days than hot ones, and in some cases snow cover might even help production by reflecting sunlight.

In the unlikely event that your system is damaged in a snowstorm, we’ve got your back. SolarCity installations come with the best coverage in the industry – we’ll take care of any repairs at no added cost.
