Does snow damage solar panels? A dusting of snow has little impact on solar panels because the wind can easily blow it off. Light is able to forward scatter through a sparse coating, reaching the panel to produce electricity. It’s a different story when heavy snow accumulates, which prevents PV panels from generating power.
What to do when snow is on solar panels? For ground or pole mounted solar PV panels or most commercial solar applications, you’re on the ground or a flat surface, so it is safer to remove snow with a soft brush. However, the same risks apply. So, just brush off the loose snow, and once again, don’t try to scrape off any frozen snow or ice.
Does snow have to be removed from solar panels? Definitely no! It is dangerous to get on your roof in snowy weather and not work the risk to your life and limbs. If your roof is covered in asphalt shingles, you also risk them cracking if you walk over them in cold temperatures. Typically, the snow will melt off your solar panels.
How do I keep snow off my solar panels on my roof?
- Use a roof rake.
- Use a soft-bristled outdoor broom.
- Blow the snow off with a leaf blower.
- Spray the snow with a hose.
- Use a softball.
- Trim back tree branches.
- Ensure the panels are angled properly.
- Use a pulley-operated tarp.
