Cleaning your solar panels: The basics

Solar panels are a fantastic investment for homeowners and businesses looking to reduce their carbon footprint and save on energy costs. However, for optimal performance, it's crucial to keep these panels clean. Dirt, dust, pollen, smog, carbon, and bird droppings can significantly reduce a solar panel's efficiency. This build up can greatly impact the power you produce while also diminishing their total lifespan, leading to premature failure and disposal.

Safety Tips

When cleaning solar panels, especially if you're working on a rooftop, safety is paramount. Always wear appropriate safety gear, including non-slip shoes, long sleeves or sunscreen, gloves, glasses, and a safety harness (if applicable). We highly recommend using a tie off point on your roof if available as an additional measure against slips and falls.

To protect yourself from electrical shock we also strongly advise disconnecting your solar panel system by turning off the solar inverter and disconnecting your panels from the electrical grid. If you are unsure of how to do this it is recommended you contact your solar installation company. You may even contact Solar Scrub Solutions and we can provide assistance with shutting off your system and turning it back on.

Cleaning methods

• DIY Cleaning: For basic maintenance, you can clean your solar panels yourself. Start by gently rinsing the panels with clean or distilled water. Use a soft-bristled brush to scrub away any stubborn dirt or debris. Avoid using harsh chemicals or stiff bristled brushes which could damage your panels or the environment. Consider using biodegradable cleaning solutions for a more eco-friendly approach.

• Professional Cleaning: For a more thorough cleaning or if you're uncomfortable working on a rooftop, consider hiring Solar Scrub Solutions. Our professionals have specialized equipment and techniques to remove stubborn stains and contaminants. We use highly purified water with a soft bristled brushes and eco-freindly cleaning solutions to properly clean you panels.

Frequency of Cleanings

The ideal amount of regular solar panel cleanings depends on several factors, including your location, climate, and the amount of environmental pollutants in your area. As a general rule, cleaning your solar panels every 2-3 months should be sufficient. However, if you live in a particularly dusty or polluted area, you may need to clean them more frequently such as monthly. Here in Colorado we recommend at a bare minimum at least two cleanings per year.

Common Cleaning Mistakes to Avoid

• Using harsh chemicals: Avoid using abrasive cleaners or harsh chemicals that could damage the panels' surface and the panels seals.

• Scrubbing too hard: Excessive scrubbing or using a stiff bristled brush can scratch or damage the solar cells.

• Neglecting the edges: Don't forget to clean the edges of the panels, as dirt can accumulate there and reduce efficiency.

• Water from a hose: Ground water from a hose often contains the very same contaminants you are trying to clean off. This water will dry and leave a spotty finish, leading to an increased need for solar panel cleanings.

Maintain your investment with cleanings

Purchasing solar panels for your home or business is an excellent way to invest back in your home and community. With regular cleanings you can avoid premature solar panel failure which is harmful to the environment. These cleanings will ensure you a also producing the maximum amount of power possible. Additionally, if you ever need to use your warranty due to faulty panels this is an great measure to ensure your warranty isn't voided due to no maintenance records.
