How to Clean Your Solar Panels for Maximum Efficiency

The Right Way to Clean Solar Panels

Cleaning your solar panels doesn’t need to be an impossible task. The best approach is to start from the ground using a hose with a high-pressure nozzle. Avoid climbing onto the roof as it poses significant safety risks. Use soapy water with a non-abrasive sponge, and squeegee off the grime without scratching the surface. Remember, cleaning should be done on an overcast day to avoid streaks and smears, and only attempt this if you can safely reach the panels without elevating yourself (Sustainable Energy Association, 2023).

Some may wonder if rain can do the job. Unfortunately, it can only remove a fraction of debris while leaving dust and bird droppings behind. Dirty solar panels can potentially reduce energy output by up to 25% (American Chemical Society, 2023). Hence, an occasional clean is essential not just for aesthetics, but for maintaining energy efficiency, ensuring your investment pays off and providing savings on energy bills.

Why Regular Cleaning is Important

Understanding Cleaning Costs

Hiring professionals to clean your solar panels typically ranges from £100 to £150 for an average three-bedroom home with around 10 panels. However, prices can vary depending on the number of panels, their accessibility, and their condition. More panels or dirty surfaces require more time and consequently higher costs. For a safe and efficient clean, consider getting these expert services rather than risking DIY mistakes (Solar Panel Maintenance Guide, 2023).

How Often Should You Clean Your Solar Panels?

Most manufacturers recommend cleaning your solar panels at least twice a year. However, once every couple of years could suffice if time is tight. A well-timed clean at the beginning of summer can significantly enhance efficiency during peak solar season. With the increasing appeal of solar-powered homes, it's a smart investment for those looking to increase property value (National Home Energy Survey, 2023).
