How To Protect Solar Panels From Rainstorms | Billy.com

Your outdoor equipment needs extra support to withstand harsh winds and downpours, including your solar panels. Protect your solar panels from rainstorms with these precautionary tips.

Choose High-Quality, Weather-Resistant Panels

Quality solar panels receive certifications to merit their ability to withstand storms and harsh conditions like heavy rain, strong winds, and even hail. Check that your panels are certified to reduce the risk of damage during a rainstorm.

Inspect Your Panels Regularly

When the forecast calls for dark clouds, inspect your solar panels for cracks, loose connections, and damaged seals. These small cracks are the perfect place for water to seep in and shorten your circuits.

If you’re unsure how to inspect your system, monitor your solar system’s health with solar labels. Attached to components like your power meter or inverter, solar labels highlight the standard voltage and performance you should expect from your system. If you notice differences in energy output, schedule maintenance on your panels before the storm rolls in.

Clean and Maintain Surrounding Gutters

One way to protect your solar panels from a rainstorm is by unclogging gutters and clearing your drainage systems. Sweep debris like leaves and dirt so that rainwater slides off your roof with ease.

Use Protective Coatings or Covers

A protective coating repels excess moisture on your solar panels. Permanent options installed by manufacturers could be beneficial for those living in stormy areas, while temporary options like panel covers protect your panels for shorter periods. However, be mindful of solar covers; remove them after the storm passes to bring sunlight back to your panels.

Trim Overhanging Tree Branches

Now’s the time to chop down those hanging branches in your yard. These branches could break or fall from strong winds and hit the solar panels on your roof. Trim your trees to reduce the risk of damage.

Ensure a Secure Mounting System

Those harsh winds can pick up anything in their path and ricochet off your solar panels. To prevent your panels from sliding, tightly secure them with corrosion-resistant mounting brackets. This way, your system can withstand weather better, extending its lifespan.

As you prepare your home for a storm, schedule routine maintenance on your solar panels. Anything from water damage to flying debris could impact the efficiency of your system. Secure your solar panels, clear off your roof, and inspect the system when you anticipate a harsh rainstorm approaching your area.
