How Do I Clean Solar Panels?

Why Is This Needed?

Once a solar solution has been installed, it is important to keep the solar panels clean. Any dust that collects on the panels will reduce the amount of power generated, which in turn extends the payback period of your solar solution.

Solar panels should be cleaned at least once per month. However, depending on the amount of dust in your area, you may need to do this more often.

Requirements

1. Turn Off The Inverter

The solar inverter needs to be shut down, so that no power is generated from the solar panels.

2. Minimise Difference in Temperature

The difference in temperature between the water used for cleaning and the solar panels should be minimise. Cleaning hot panels in the middle of the day with cold water increases the risks of cracks forming due to a sudden change in temperature.

3. Safety Equipment

Utilise safety equipment to prevent any injuries due to a fall from the roof.

4. Avoid Underside

The underside of the solar panels should not have any contact with water, as the wiring is present there. This can lead to an electrical short-circuit and damage to your solar installations.

Cleaning Approaches

Here are a few approaches to cleaning:

Water, Soap and Sponge

Mild soap and water, applied with a soft sponge, work well in cleaning the solar panels.

Water Hose

If water pressure is sufficient, a hose can be used to clean the panels. However, one needs to be careful about water splashing onto the underside of panels.

Regular Panel Cleaning Service
