Should you hire a professional company to clean your solar panels? The short answer? Absolutely. The longer answer?
Read on to find out why
Over the past few months, you may have heard some chatter about how it is not necessary to have your solar panels cleaned by a professional. Not surprising. According to some solar panel companies, a homeowner can clean their solar panels themselves, and office buildings can use their maintenance crew to clean the solar panels. Their claims are only growing in popularity because it is not in the best interest of these companies selling the panels to tell the buyer that it is best they have their panels cleaned every six months by a professional company. As with any company trying to make a sale, they will avoid telling you that there may be a small extra effort involved with your purchase.
However, experts are chiming in with Studies that show the importance of maintaining your solar panels clean.
What is a solar panel, and How Does it Work?
Solar panels work by converting sunlight into electricity, so the cleaner the panels the more efficiently they can generate energy for the home or business. Although we don’t ever think about it, solar panels can get quite dirty. Many outdoor elements can make a panel dirty, including dust, pollen, and bird droppings to name a few.
Are Dirty Solar Panels really a Concern?
Think about it, with most other outdoor windows in a home or of a car left outside, dirt can build on the glass, and it would make it difficult to see through without ever cleaning it. Even if it rains and it looks like it was cleaned you may still have to use other cleaning methods to get it really clean and be able to see through the window or windshield. Likewise, having dust, grime or pollen buildup on your panels can reduce your system’s energy yields by up to 20%, and you may see reductions in energy bill savings.
A 2017 report from the International Energy Agency found that long term dirt buildup can reduce solar panels electricity production by as much as 20%. They found that the dust reduces the radiation on the solar cell and it also changes the angle of incidence of such radiation. (World Renewable Energy Congress 2011 Sweden).
A solar panel functions best with unobstructed access to the sun’s rays for most or all of the day. A residue layer of dust or pollen can affect the performance of your panels, while more significant spots & obstructions can have a larger impact on the performance of your panels.
