How To Clean Solar Panels on Roof

As a homeowner with a solar panel system, keeping your solar panels clean is essential to ensure their performance and longevity. Dirt, dust, and debris can accumulate on your panels over time, reducing their ability to absorb sunlight and generate electricity. Fortunately, with a few simple steps, you can keep your solar panels in top condition.

Why Do Solar Panels Need Cleaning?

Solar panels need cleaning to maintain their efficiency and output. Dirt, dust, and grime can accumulate on the surface of panels over time, reducing the amount of sunlight that can be absorbed and converted into energy. Cleaning the panels helps remove these obstructions, allowing the panels to function at their maximum capacity and produce more electricity.

How Often Should I Clean My Solar Panels?

The frequency of cleaning your solar panels depends on various factors such as location, air pollution, and weather conditions. In general, you should clean your solar panels at least once or twice a year, or when there is a noticeable decrease in energy production. However, if you live in an area with high levels of dust, pollution, or heavy rainfall, you may need to clean them more often. It’s best to inspect your panels regularly and clean them when necessary.

To Clean Solar Panels:

Do:

1. Use a soft cloth or soft-bristled brush to avoid scratching the panels

2. Use water and a mild soap solution to clean the panels

3. Avoid cleaning on hot or sunny days to prevent the soap from drying too quickly and leaving streaks

4. Rinse thoroughly with water to remove soap residue

5. Wear protective gear, such as gloves and eye protection, if necessary

2. Use high-pressure water to clean the panels, as this can cause damage to the seals and connections

3. Climb onto the roof or panels without proper safety equipment and training

4. Clean the panels during an electrical storm or when the panels are live (i.e. connected to the electrical system)

When Should I Call in the Professionals?

You should consider calling in a professional for cleaning solar panels when:

1. The panels are too high or difficult to reach safely without proper equipment.

2. The panels are covered in dirt, grime, or other substances that cannot be easily removed with household cleaning products.

3. You want to ensure that the panels are cleaned correctly and thoroughly to maximize their energy efficiency.

4. You are concerned about causing damage to the panels during cleaning, or potentially voiding the warranty.

5. Regular cleaning is necessary, and you prefer to have a professional handle the maintenance on a regular basis to keep the panels in optimal condition.
