How to Wash Solar Panels

Solar panel conversion efficiency, typically in the 20% range, is reduced by dust, grime, pollen, and other particulates on the solar panels, collectively referred to as “soiling.” “A dirty solar panel can reduce its power capabilities by up to 30% in high dust/pollen or desert areas.”
Solar energy is sustainable power for domestic and commercial purposes. Solar panels need maintenance for better efficiency and performance. In this article, we will share the importance and methods of how to wash solar panels.

Solar Panels Need Cleaning

Solar panels need cleaning to maintain their efficiency and performance. They are installed to self-clean through rainwater. Debris, dust, bird droppings, and pollutants on solar panels obstruct sunlight and reduce efficiency. Therefore, washing solar panels is very important for getting the maximum output of solar panels.

When should you wash solar panels?

There is no need to clean the solar panels daily. This depends upon the condition of the environment. If there is excessive dust, storms, and rain for a long period, then the solar panels should be washed frequently. If the environment is very harsh, then solar panels need cleaning once every six months. If you live near a construction site, highway, or coastal area that accumulates debris on solar panels. Solar panels require regular maintenance.

Cleaning solutions required to wash solar panels?

Solar Sathi will share the four best cleaning solutions.

Soap Water

Wash solar panels by mixing the water with mild soap. Rinse off softly by using the scrubber. Soap water not only cleans the solar panels but also avoids chemical damage.

Hydrophobic coating

A hydrophobic coating is the best alternative solution for cleaning the solar panels. This hydrophobic coating is known as an ultra-thin, invisible layer. This layer not only protects the solar panels but also enhances the performance of solar panels. This layer prevents sunlight obstruction caused by the debris.

Low-Pressure Washer

Rinse the solar panels with a low-pressure washer. Washing solar panels with low-pressure water removes extra dust and dirt. Retain the low pressure because high pressure damages and scratches the solar panels.

Professional Service

This is the last option if you do not want to clean or wash the solar panels yourself. Get the professional services from a reputable company.

What Should You Avoid When Washing Solar Panels?

Avoid harsh and strong cleaning agents, detergents, and harsh clothes. These strong cleaning agents can damage the surface of panels.
Never stand on panels; these can crack the solar panels.
Install a CCTV camera to monitor the condition of your solar panels.

Maintenance of Solar Panels (Tips)

The efficiency of solar panels is reduced when they are placed in shade. So, keep the solar panels out of any shade.
Monitor the solar panels and inverters. Inverters should flash the green light.
Document the performance of solar panels day to day.
If you do not have time for cleaning the wash solar panel, then install the automatic cleaners.
