Solar panels are exposed to various environmental elements like dust, dirt, pollen, bird droppings, and other debris, which can accumulate on their surface over time. The build-up of grime can reduce the efficiency of the panels, leading to decreased energy production. Regular cleaning ensures optimal performance and maximizes the return on your solar investment.

The frequency of cleaning largely depends on your location and the prevailing environmental conditions. In areas with heavy pollution or significant dust and dirt accumulation, cleaning every 3 to 6 months may be necessary. In less polluted regions, annual cleaning might be sufficient. Additionally, it's a good idea to inspect your panels regularly and clean them when you notice significant dirt build-up.

Cleaning solar panels is possible for homeowners, but it requires careful handling and some precautions. If your panels are easily accessible and on the ground level, and you can safely reach them, cleaning them yourself may be an option. However, if the panels are installed on the roof or in a high and difficult-to-reach location, it's safer and more advisable to hire a professional service

When cleaning solar panels yourself, follow these steps:

Check the manufacturer's guidelines to ensure you won't void the warranty.

Clean the panels early or late in the day when they are cooler to avoid thermal shock.

Use clean water and a soft, non-abrasive sponge or cloth to gently remove dirt and debris.

Avoid using harsh chemicals, abrasive cleaners, or high-pressure water as they may damage the panels.

Dry the panels with a soft, clean cloth to prevent water spots.
