Solar Panel Cleaning: Step-by-Step Guide

Cleaning solar panels is a must to harvest maximum energy. But if you do it wrong, you will end up damaging solar panels.

In this article, we will explain how you can clean solar panels. We will share the equipment needed, dos & don’ts, and the step-by-step process of cleaning.

Why to Make Solar Panel Cleaning?

Dust, dirt, bird droppings, and other things accumulate on the solar panel surface over time. They decrease sunlight absorption and reduce the efficiency of the solar panel. Thus, the output is decreased.

In coastal regions, the saltwater particles in the air can damage solar panels if not regularly cleaned. Similarly, in dust storms, heavy dust covers the surface and does not allow sunlight to pass through.

For maximum energy production, it is necessary to clean solar panels on a regular basis. It also prevents damage and increases the panel’s lifespan.

When to Clean Solar Panels?

Energy Production

Keep an eye on the energy production of the solar panels. If the production is low even in favorable conditions, it means the panels could be dirty. A thorough cleaning will improve energy production.

Local Weather Conditions

Consider the local weather conditions. If you live in a rainy area, you might not require frequent cleaning. But areas that are affected by dust storms need regular cleaning. Adjust the cleaning frequency according to your local weather conditions.

The Time of Day or Year

For solar panel cleaning, the best time of the day is early morning or late afternoon. You can see everything clearly and even clean the panels on pitched roofs. Do not clean during the hot time.

The time of the year depends on your locality. You might need to clean more in several months due to weather conditions.

Brush Attachment

The brush attachment effectively cleans your solar panels without harming them. It removes dust, dirt, bird droppings, grease, and other things quickly.

Telescopic Lance

A telescopic lance is needed to reach every corner of the solar panel without moving here and there. Its extendable length is quite beneficial for solar panel cleaning. It can be attached to a pressure washer, and you can adjust the brush attachment at its top.

Roller Brushes

Roller brushes are also effective in cleaning the top surface. They remove debris and evenly clean every corner. It is also a safer option for the solar panel surface.

You can go with any glass cleaner that has a neutral pH and no harsh chemicals that could destroy the surface of the solar panels.

Ladder

A ladder is needed to reach solar panels if they are placed at a certain height. It is better to have an adjustable ladder for this purpose.

Solar Panel Cleaning Solution

1. Turn off your solar panel system to ensure your safety. Electrical shocks are hazardous. Get ready with the safety gear, such as shoes, helmets, and gloves. If you are working at a considerable height, a safety harness is also required.
2. Prepare the cleaning solution in a bucket. Make sure to use clean and deionized water.
3. Spray water on the surface. Use a soft brush to clean the surface of the solar panels. Remove bird droppings, dirt, etc.
4. Use the cleaning solution on the solar panels. It can be applied with the help of a telescopic lance. Scrub on the surface of the solar panels and gently clean.
5. Finally, rinse the solar panels properly. There shouldn’t be any cleaning solution left on the surface. Let the solar panels dry on their own.

Tips for Solar Panel Cleaning

What Should Not Do When Cleaning Solar Panels

• Do not use common detergents, bleach, or any other chemical. Choose a suitable solar panel cleaner to prevent damage to the surface.
• Do not stay on the ladder without a harness. You could slip, which is why safety is needed.
• Do not walk on the solar panels. It will damage or break the surface or cells.
• Do not use hot water to clean the solar panels. It could damage the top layer.
• Do not use hard brushes and abrasive materials to clean the surface. Use a soft brush or cloth.
• Do not clean the panels when the system is turned on, as there is a risk of electric shocks.
• Do not use high water pressure directly on the solar panels. It can damage cells and the seal around the panels.

Safety Consideration When Cleaning Solar Panels

• Ensure your safety. Wear safety gear like gloves and boots. Use a safety harness while working at a certain height.
• The ladder should be stable and sturdy. It’s better to have a dedicated place to secure the ladder.
• Turn off the solar panel system in the first place.
• Clean panels in suitable weather conditions to ensure your safety. Heavy rain, wind, and other unfavorable conditions increase the risk of accidents.
