Why Clean Solar Panels?

Your solar panels contain photovoltaic cells that convert sunlight into electricity, and these need to be unobstructed to fully absorb the sun’s rays. Pollon, dirt, dust, algae, exhaust fumes from vehicles, and other particulates can form a thick layer on your solar panels and ultimately block sunlight from being absorbed by these cells. With a regular cleaning to remove debris and particulates, you will maximize your energy production. -We have had clients report an output increase of up to 30% after a cleaning!

Why Should You Clean Your Solar Panels?

Solar panel cleaning is essential for maintaining optimal performance and maximizing the investment in solar energy. Here are several key benefits of regular solar panel cleaning:

Increased Efficiency and Performance

Pollen, dirt, dust, bird droppings, and leaves can significantly reduce the amount of sunlight reaching the solar cells, leading to decreased efficiency and power output. Clean panels ensure maximum exposure to sunlight, thereby increasing the overall efficiency and performance of the solar energy system.

Prolonged Lifespan

Regular cleaning helps to prevent the buildup of materials that could cause long-term damage to the solar panels. By maintaining clean panels, you can help prolong their lifespan and ensure they continue to operate effectively for many years.

Early Detection of Issues

Having a technician up on your roof to regularly clean your solar panels provides an opportunity to inspect the system for any damage or issues, such as cracks, loose wiring, or bird’s nests. Early detection of these problems can lead to quicker repairs, preventing more extensive and costly damage.

Maximizing Return on Investment (ROI)

Solar panels are a significant investment, and their efficiency directly impacts their return on investment. By keeping panels clean and operating at peak efficiency, you can ensure a faster payback period and greater savings over the life of the system.

Maintaining Warranty Coverage

Some manufacturers or installation companies require regular maintenance, including cleaning, as part of their warranty terms. Regular cleaning ensures compliance with these terms, keeping the warranty intact and providing peace of mind.

Reduced Energy Costs

The more electricity your solar panels generate, the less you rely on the grid, leading to lower energy bills. Clean solar panels ensure you're getting the most electricity possible, maximizing your savings.

Environmental Benefits

Solar energy is a clean, renewable resource. By ensuring your solar panels are operating efficiently through regular cleaning, you're maximizing the environmental benefits by reducing reliance on fossil fuels and lowering carbon emissions.

Aesthetic Appeal

Clean solar panels have a better appearance, maintaining the aesthetic appeal of your property. This is particularly important for businesses or homeowners who value curb appeal or are subject to community standards regarding property maintenance.


Your solar cells are covered with a sheet of tempered glass. When we clean solar panels we carefully soak this tempered glass in a biodegradable detergent solution, give a thorough scrub with a soft bristled brush, and rinse clear. We will also clean the bottoms of the frames that often accumulate an unsightly build up of grime and moss.

We recommend cleaning your solar panels once or twice a year to maintain optimal efficiency. However, if you're in an area with a lot of tree cover, high pollen or dust levels you might need more frequent cleanings.

While a heavy rain might rinse away some leaves and larger debris, it will not remove the baked in dirt or remove algae, moss or lichen that can cover your solar panels. Much like a car that is left outside over an extended period of time, your solar panels will accumulate a thick layer of build-up on the surface. This will lead to a decrease in your solar panels energy output.

Absolutely! Even a thin layer of dust or grime can significantly reduce your solar panels' efficiency. Regular cleaning ensures they operate at peak performance, maximizing your energy production and savings.

This can vary based on the number of panels you have installed and their accessibility (i.e. a walkable one storey roof is a lot easier to access then a steep metal roof three storeys high). We will put together an estimate free of charge so you have itemized pricing before any work begins.

It depends. Often on taller homes with steeper roofs we will do the cleaning from ladders along the roof’s edge. When possible, we may use roof access to clean your solar panels if it provides an easier or safer approach.

It depends on how many solar panels you have and the condition they are in, but most residential solar panel cleanings can be done in a few hours.

Spring is often considered the best time to clean solar panels to prepare for the high-production summer months. But, cleaning is beneficial any time of the year, especially if you notice a significant drop in efficiency.
