With welcome warmer weather, it’s likely your list of things to do for Spring-cleaning is taking shape. While you’re cleaning the gutters, making sure the lawn mower is ready, and stowing heavy winter jackets in the attic, don’t forget to schedule a solar contractor to clean your solar panels. If your home is utilizing solar power, cleaning the panels isn’t just a chore that needs doing – it’s a great way to improve efficiency and save yourself some money.
Do I Need To Clean Them?
Unless your panels are entirely coated with dirt or mud, they don’t “need” to be cleaned. They will still absorb solar energy and provide your home with clean, renewable energy. Perhaps a better question to ask is, “Is it beneficial to be sure my solar panels are clean?”
Dirty solar panels, besides being a bit of an eyesore, cannot absorb solar energy as efficiently as they can when they are clean. A simple explanation is to think of windows with the curtains drawn – some sun still gets into the home, but not nearly as much as when the curtains are thrown open and sunlight can pour in. Muddy or visibly dirty panels can have their production significantly hindered – research has shown that dirty solar panels may generate up to 30% less power than when they are clean. Basically, making sure your solar panels are clean greatly maximizes the energy they produce.
Tips For Cleaning
Although some homeowners are comfortable accessing their roof to do routine maintenance, we strongly recommend hiring a renewable energy contractor to clean your solar panels. Not only will a solar professional clean your solar panels, but also inspect your system to ensure that it is performing to the highest standards. Check with the company that installed your system to see if they offer routine operations and maintenance services, if not, reach out to other local contractors to see if they offer these services. Most companies recommend cleaning every six months, but you can visually check your panels at any time and determine if you believe it’s time to have them cleaned.
