If you have recently gone solar, you may wonder how often you should clean your solar panels. Dirty solar panels can lead to reduced efficiency and decreased power output, but how often should they be cleaned? The answer is that it depends on your local climate, the angle of your roof, and other factors like nearby trees or animals that can leave debris on the panels. Let’s explore the best ways to keep your solar panels clean, so they remain efficient and productive.
What Causes Solar Panel Degradation?
Solar panel degradation is generally caused by dirt, dust, pollen, bird droppings, and other debris that accumulate over time on the surface of the modules. This build-up of contaminants decreases the amount of sunlight reaching the modules’ cells and reduces their output efficiency. It means less electricity is generated by each panel which can reduce system performance and generates higher energy bills for homeowners. The energy loss depends on how much dirt is stuck to your panel; if there are multiple layers of dust and dirt, you could lose up to 40% of your potential power! That’s why regular cleaning is essential for optimal performance.
When Should I Clean My Solar Panels?
The frequency you need to clean your solar panels will depend on your specific environment because some areas are naturally dustier than others. Generally speaking, it’s recommended that homeowners have their solar systems professionally cleaned at least once a year or as needed depending on where you live and what type of tree cover there is near your house. Additionally, if you live in an area with heavy snowfall during winter, pay close attention to any snow accumulation or ice build-up on top of the modules. Check your panels regularly every three months—especially after major storms or high winds—and give them a good cleaning when necessary. Keep in mind that it’s best not to scrub too hard; use soft cloth or a squeegee, so you don’t damage the panel’s surface.
Keeping Solar Panels Clean
Cleaning your solar panels can be difficult, especially when they are roof-mounted at an angle, which means they need to be reached from above with a ladder or special equipment. If you decide to do it yourself, use only water (no soap) and a soft brush or microfiber cloth to avoid scratches or other damage. Additionally, never climb onto a roof without proper safety equipment. If all else fails or heights make you uneasy, hire a professional service provider specializing in solar panel cleaning. They will have the necessary tools and expertise required to clean them while avoiding damage safely.
Extra Tip:
There are several steps you can take beyond simply cleaning them yourself. First, ensure that there aren’t any trees near your solar array that could cast shade over the panels; this will reduce their effectiveness even if they’re kept clean. Additionally, consider installing an automatic cleaning system like Rain-X® or EcoBrite®; these systems use sensors and aerosol sprays to keep your panels shining brightly throughout every season.
To Sum Up
Solar panels are an excellent way for homeowners to reduce their energy costs while helping out our planet by using renewable energy sources instead of non-renewable ones like coal or oil-based fuels for power generation. But just like any other appliance in your home, keeping them clean is essential for optimal performance and efficiency. Depending on where you live, cleaning intervals may vary from once a month up to once a year; however, if properly maintained with regular attention, most systems should last for many years without issue. Just remember—safety first! So if heights aren’t your thing, hire someone who knows what they’re doing when it comes time for maintenance work on those rooftop modules.
