Do I Need To Clean My Soar Panels?

Post by : Elliot Preece on 10.03.2020

Solar panels are a significant investment for both your family and the environment. These panels work at their peak when the surface is free of debris. However, even though most solar panels on the market claim to be self-cleaning, it’s still necessary to manually clean them once or twice a year to ensure optimal performance.

When should you clean your panels?

Hiring a professional to clean your solar panels is the best option. Most companies recommend scheduling a cleaning service during the spring or summer because there is less chance of rain. However, if you notice a visible layer of dust, it may be necessary to clean your panels during the other seasons.

Another sign you need to clean your solar panels is a sudden drop in power. Ideally, your panels should produce enough energy from the sunlight to power your house both day and night. But if the panels are dirty, they may not convert energy as easily. Deep cleaning the surface should clear up the issue.

The cleaning process

Cleaning your solar panels is a straightforward process. It involves wiping down each panel with a gentle detergent and rinsing away the residue. Before you begin, make sure you turn off the entire system. The wires on your roof are high voltage, so take the necessary precautions to avoid shocking yourself. You should inspect the cabling for any signs of damage at this time.

You can purchase an all-in-one kit to cover the solar panel cleaning cost from a local tradesman or a hardware store. These kits often include biodegradable soap, a wiper, and a brush. To clean your panels, simply dip the brush into the soap and rub the surface. Use the wiper to clear away any excess soap, and always rinse with fresh water.

Some houses have hard water in the mains, which can leave behind unwanted spots. Since these spots may reduce the performance of your solar panels, always wipe the panels dry to prevent mineral residue.

The cost of cleaning

If you don’t have the confidence or tools to clean your solar panels, you should hire a professional. Most traders charge about £150 for the entire roof, but you may be able to pay a per-panel fee of between £4-15. This option is best if you only have a few panels on your roof. Always inquire about costs before you schedule service.

Cleaning the panels yourself may take the entire day. Plus, you risk damaging your roof or injuring yourself. A cleaning company can often clean 20 panels or less on the ground floor in about half an hour. A full roof with more than 40 panels should take about 1-2 hours to complete. Although you’ll end up paying a bit more to hire a professional, you’ll save a lot of time and energy in the process.
