Removing Snow is Part of Maintenance.
Snow isn’t a concern for most California solar homeowners, but it can be an issue in higher-elevation and snow-prone areas of Northern California. A heavy accumulation of snow can temporarily reduce solar production by blocking sunlight from reaching the panels.
In many cases, the safest option is simply to let the snow melt and slide off naturally. Solar panels are typically installed at an angle, and their smooth surface can help snow shed as conditions warm. If snow does need to be removed, protecting both yourself and your solar equipment should be the priority. Avoid climbing onto a snowy or icy roof, and contact a professional if the panels can’t be safely reached from the ground.
What are some different ways to remove snow from solar panels?
If snow is affecting your solar production, the safest approach depends on how much snow has accumulated and whether your panels can be reached safely from the ground. Here are five options to consider:
1. Let it melt naturally.
Often, the best solution is to wait. As temperatures rise and sunlight reaches the panels, snow may begin melting and sliding off on its own.
2. Use a solar panel snow rake.
If your panels can be reached safely from the ground, a roof rake specifically designed for solar panels may help remove loose snow. Choose one with a soft, non-abrasive surface to avoid scratching the panels.
3. Remove only loose snow.
Gently clearing some of the loose accumulation may allow sunlight to reach the panel surface and help speed up natural melting. Never scrape or chip away ice.
4. Monitor production and weather conditions.
Sometimes no removal is necessary at all. If warmer or sunny weather is coming, waiting may be safer than attempting to clear the panels yourself.
5. Call a professional.
For heavy accumulation, hard-to-reach panels, ice buildup, or any situation that would require climbing onto a snowy roof, professional assistance is the safest choice.
What Should You Avoid When Removing Snow From Solar Panels?
Avoid using rock salt, chemicals, abrasive tools, or anything that could scratch or damage the surface of your solar panels. Never pour hot water onto cold or frozen panels, as sudden temperature changes could potentially damage the glass.
Most importantly, don’t put yourself at risk to clear snow from your solar system. Avoid climbing onto a snowy or icy roof. If snow or ice isn’t clearing naturally and you can’t safely address it from the ground, contact a professional for assistance.
In many cases, a little patience is all that’s needed. As the sun returns and temperatures rise, snow can begin to melt and slide away naturally, allowing your solar panels to get back to producing power.
