More homeowners are going solar, but many have questions about cleaning solar panels. It’s a significant investment, so keeping those panels clean is important. While it seems simple, certain steps must be followed.
Cleaning solar panels is essential for maintaining their efficiency. How often should you clean them? What’s the best way to do it without causing damage? You’ll learn how to optimize your solar energy system’s performance through simple cleaning.
Solar panels convert sunlight into electricity. This requires maximum sun exposure. Dust, dirt, pollen, bird droppings, and other debris obstruct sunlight, reducing panel efficiency. Studies by the National Renewable Energy Laboratory (NREL) show that soiling can significantly reduce your system’s output.
One system’s output dropped by nearly 10% in just a few dusty months, causing a noticeable increase in their electricity bill. After cleaning the panels, energy production returned to normal. Regular cleaning is easy and ensures peak performance.
For many locations, cleaning your solar panels twice a year is sufficient. Consider your specific environment. Living near dusty roads, construction zones, airports, trees nearby, or in wooded areas might require more frequent cleaning, perhaps every three months.
Frequent cleaning is a must for some homeowners. If rain washes your panels every few weeks, annual cleaning might be enough. Even then, check for stubborn dirt.
The tilt angle also matters. Flat or slightly sloped solar panels accumulate dirt faster than steep ones because rain doesn’t run off as well. Consider this when installing your panels.
Cleaning your solar panels requires a systematic approach, especially with more frequent cleanings.
Turning off your system before cleaning is crucial for safety. This prevents electric shock. Consult your system’s instructions for the proper shutoff procedure.
Use a soft-bristled brush or a brush attached to a telescoping pole to remove loose debris. This prevents scratching during cleaning.
Use a gentle spray from your garden hose. Avoid pressure washers, as high pressure can damage the panels.
If water isn’t enough, use soapy water. Mix a little mild dish soap with water and apply with a non-abrasive sponge or soft cloth.
Gentle cleaning is always best. Using the correct cleaning agents will help to extend the life of your solar panels.
Water spots can reduce light absorption, so dry the panels thoroughly. Use a soft cloth or squeegee, then rinse with clean water to prevent soap buildup.
Plain water is usually sufficient. For tougher dirt, use water mixed with mild dish soap.
Rain helps, but periodic cleaning maximizes energy production. Debris buildup affects efficiency.
If you’re comfortable on a ladder and your roof isn’t too steep, you can clean your own panels. Follow safety precautions for safe solar panel cleaning. Professional cleaning services are also available.
Avoid pressure washing. High pressure can crack the glass or damage the panels. It’s always best to avoid damaging your PV panels.
Cleaning solar panels is easy and has significant benefits. Regular cleaning is vital for maximizing your solar investment and lowering electricity bills. Cleaning companies and professional solar panel cleaners offer their cleaning services, too. However, if you live in a harsh environment or near something that would attract birds, like wooded areas, you might consider hiring a professional cleaning service or one of the many panel cleaners to conduct professional solar panel cleaning.
Remember these instructions for safe and effective cleaning to ensure optimal panel performance and proper care. If you don’t have time, remember there are companies who provide professional solar cleaning. Your PV panel or PV panels rely on being clean. Cleaning portable solar panels, on the other hand, are cleaned more easily since they aren’t installed. Cleaning solar panels can extend the life of them for a positive effect on solar panel production and reduce the number of times they must be cleaned. Dirty solar panels will only result in needing to clean them more often which takes more work, however you choose to accomplish it. So if you get a chance, try to get those solar panels cleaned today for maximum performance.
