How to Clean Solar Panels

Solar panels are not just for the green-conscious people who want to save money by reducing their electricity bill and reduce their carbon footprint. Professional as well as residential users of solar power systems are now employing innovative ways to clean solar panels that can help in optimizing performance and longevity of the solar panels.

The advent of new solar panel technologies like thin-film has made cleaning procedures more complex, but it is not that much different from traditional cleaning methods.

Clean solar panels

If you have solar panels, you need to clean them every so often.Cleaning your solar panels is essential to keeping them working at their best and getting the most out of each day.Although they’re durable, it’s important to clean off any dirt or dust as soon as possible in order to keep your system running smoothly and efficiently.

Dirt acts like an insulator and can affect that how much power your system produces for you throughout the year. It will also make it harder for the sun’s rays to reach the cells on your panel, which means it’ll take longer for them to produce energy when they aren’t covered in grime or dust.

Use a soft brush to remove dirt and dust

  • Use a soft brush to remove dirt and dust on the panels.
  • Use a microfiber cloth if you want to avoid scratching the surface of your panels.
  • Use distilled water when cleaning the solar panels. Distilled water is purer than other types of water, so it can help prevent mineral buildup on your solar panels.

If you have hard water in your area, it can build up on the surface of your panels and cause damage over time.

  • Cleaning your solar panels regularly with distilled water will help prevent this from happening.
  • Clean your solar panels with soap and water once per month or as needed. You should clean them sooner if they appear dirty or if rainwater pools on them after cleaning them off when it rains.

Detergent and water

The first step to clean solar panels is to cover them with a plastic sheet or tarp. This will protect the solar panel from dirt and dust, which can scratch the surface or cause other problems. Then, use your garden hose to spray water onto the solar panel. Use a soft-bristled brush or rag to scrub away any dirt that remains on the panel.

Detergent and water can effectively clean solar panels. If you use soap, make sure it is non-ionic surfactant or mild dish soap. Avoid using harsh chemicals such as bleach or ammonia because they may damage the surface of your panels and reduce the efficiency of the solar panel.

Remove the dirt and debris with a soft cloth

Cleaning your solar panels is an important step in keeping them working properly. Dirty solar panels decrease efficiency and may result in poor performance.You can clean your solar panels by hand, using a soft cloth, a garden hose or high-pressure power washer.

Remove the dirt and debris with a soft cloth, a garden hose or a high-pressure power washer. Use water that is warm or hot enough to remove any stuck-on dirt without damaging your panels. Do not use anything abrasive on the surface of your solar panels.
