Top 5 Reasons to Clean Solar Panels Before Summer

Solar Cleaning: Why Timing Matters

#1: Post-Pollen Spring Cleaning

If you're a native to North Carolina, you know how bad the pollen can be in the Spring. Most panels are left with a yellow-ish film coating that can block sunlight and reduce efficiency. Even rain can't remove the sticky buildup completely.


A professional spring cleaning for your solar panels ensures they are pollen-free and hinders future buildup to keep them working efficiently for the long summer days ahead.

#2: Maximize Summer Solar Production

Most homeowners see higher energy  production during the summer months due to the longer sunlight hours and better angles. There are also fewer cloudy, dreary days like in the previous Fall, Spring and Winter months.


If your panels are dirty, you won't fully benefit from North Carolina's Summer sunshine.

#3: Save on Cooling Costs

Your AC system will likely be running full-time or near it throughout the summer. A more efficient solar system can offset those higher bills, but only if it's performing its best. Filthy panels that aren't collecting full sun are going to dull your production.

#4: Catch Potential Issues Before Peak Heat

Our professional cleanings are not just for making them shine again. We also perform a thorough visual inspection of your system to help catch issues early on. This can be anything from wear, loose or frayed wires, pest damage, or other panel issues.


Not every homeowner can or wants to get on their roof to inspect their panels - so we do it for you! Catch issues before the long summer days start!

#5: Beat the Summer Rush

As summer approaches, our schedule tends to fill up very fast. By scheduling your cleaning appointment in Spring, you avoid the peak-season rush and start Summer with sparkling clean panels.


Make sure your system is fully prepped before the most demanding months of the year.

Solar panels are a great addition to your home if you're looking for a way to save money on energy costs and contribute to a sustainable future. However, like many other items in our lives, regular maintenance is required to keep them operating effectively. This is why cleaning solar panels is so important. Let's talk about how to clean them properly. The Basics of Cleaning Solar Panels Cleaning solar panels is not as simple as hosing them off or using household cleaners. Letting the rain "do the cleaning for you" is unfortunately not a solution either. Rain can leave behind dirt, pollen, and mineral deposits that only impede on your solar array's performance. To clean solar panels effectively, we use solar-safe methods that include: 100% Chemical-Free: Harsh chemicals can degrade the surface and/or leave a residue on your panels Deionized Water: Free of impurities which ensures a spotless, streak-free finish with no mineral buildup Specialized Equipment: Using non-abrasive tools designed specifically for the job prevents abrading the surface of your solar array Safety is a Priority Cleaning solar panels often involves working on rooftops and other elevated surfaces, making safety a top concern. This is why it's essential to: Use the appropriate safety gear such as harnesses and other fall-protection equipment Avoid standing directly on the solar panels to avoid breakage or injury Exercise caution when working on wet surfaces to avoid slipping Without the proper equipment, cleaning your own solar panels can be dangerous. Sometimes it's best to leave these things to the professionals. Why Trust Solar Clean NC to Clean Your Solar Panels? We are a fully licensed and insured solar cleaning service provider.
