Just over 3% of U.S. energy supplies come from solar power. With lower production costs and rising utility prices, solar panels have now become a viable product for homeowners. But how do you ensure your system is running at peak efficiency?
One way is to keep them clean and well maintained. Read on as we discuss how to clean rooftop solar panels.
Why Clean Solar Panels?
There are two opposing trains of thought when it comes to cleaning solar panels. Some people believe that rainwater will clean them naturally. Others think that if you don’t get onto them and scrub, you are sacrificing efficiency.
If you live in an area where you don’t get much rain and the climate is dusty, you will need to clean them anyway. The truth is that whatever the climate a little bit of both is true. Rainwater will clear some of the dirt but occasionally, you will need to give them a more vigorous scrub.
How to Clean Rooftop Solar Panels
If your solar panels just need summer dust removal, then a hose down should work. Spray them with a garden hose then let them dry in the sun. If you use a pressure washer, make sure it is on the most gentle setting so you don’t damage the panels.
When your panels are mounted on the roof, this becomes much harder. Make sure you have a secure ladder or the right safety equipment. Get someone to help you and hold any platform you are using to climb.
Deep Cleaning Solar Panels
Occasionally, you may have stains on your panels that a simple hose won’t remove. Bird droppings and tree sap are the main offenders. For this, you will need a sponge, squeegee, and a soft cloth in a bucket of warm water.
Locate the stains, being extremely careful if you are on a rooftop. Apply water using the sponge, then clean using the squeegee in a repetitive motion. Don’t scrub hard but have patience, as vigorous scrubbing could damage the panel.
Solar Panel Tips
Even mild soaps and cleaning products that claim they are suitable for panels may cause damage. If you can’t remove a set-in stain, you can create a cleaning mix. Use a slight squirt of dish soap along with a cap of vinegar, diluted with around 8 parts water.
Any soap used should be rinsed off with clean water afterward. If left, dirt will attach to this residue which will dry out. This can be even more stubborn to remove than droppings and tree sap.
Get Professional Services
If you don’t want to take the risk with your panels, then consider a professional service. Not only will they clean your panels, but they can check them for any damage, repairs, or efficiency. Visit website and social media pages of experts like Blue Raven for more information.
