If you have a solar power system at your home or business, you may be wondering if you need to clean your solar panels. Cleaning your solar panels is not something you need to do weekly but over time they can become dirty and need cleaning. Bird droppings, leaves, pollen and other debris can be stuck to the panels making them less effective at collecting energy. If it hasn’t rained recently and you are noticing a lower than average energy collection, it’s probably time to clean your panels!

Solar panels can be extremely hot, and cleaning them takes some knowhow. Just like washing your car on a hot day, the water can dry before you even have a chance to wash away the debris. Leaving the hard work to a professional solar panel cleaning company can save you time and effort.

If you live in an arid climate, or an area that is in a drought, your panels may become dirtier than normal. Rain is good for cleaning solar panels, but it cannot do all the work. Hiring a professional to clean your solar panels is a great way to maintain the integrity of the system and avoid climbing on your roof. That’s dangerous business that’s best left to professionals. Some companies even offer an annual maintenance service for cleaning your solar panels. Often the cost of the cleaning is covered by the increase in energy collection. Clean panels = increased efficiency = more savings!

The first step to cleaning the solar panels is to inspect the panels for debris. Then you will want to check if the panels are working effectively and look for anything that may need maintenance. Your solar panel company can advise you on what cleaning materials are allowed. Most commonly, soapy water and a hose are all you will need. A non-abrasive sponge may also be used. DO NOT use a pressure washer. If you need something stronger than soapy water, you will want to check with your manufacturer first to ensure you do not damage the panels.

During your solar panel cleaning you may also consider having the gutters and roof line cleared of any debris. Keeping your roof well maintained will help to ensure the integrity of your solar panel system down the road. Window washing, and solar panel cleaning, are two projects that are best left to the professionals for superior results.
