Why You Should Clean Your Solar Panels

You shouldn’t neglect the important duty of cleaning your solar panels. Solar panels are minimal maintenance and made to survive various weather situations, but they are nevertheless prone to gathering dirt, dust, and other debris over time. This dirt buildup may significantly impact your solar energy system’s efficiency, which could lead to lower energy output and increased energy bills. However, there are different ways and practices to adopt for cleaning commercial and residential types of solar panels. There are other commercial solar panel cleaning practices compared to residential solar panel cleaning. 

Maintaining your solar panels’ effectiveness and extending their life requires routine cleaning. The quantity of solar energy cells that can convert can decrease if dirt and other debris have accumulated, forming a barrier between the sun’s rays and the solar cells. Your panels can absorb the most sunlight and produce more energy if you regularly clean them to keep them clear of obstacles.

Keeping your panels clean is crucial for preserving your warranty and insurance plans, as well as for maximizing energy output and extending the lifespan of your panels. If you clean your panels, you can avoid losing these advantages and paying for pricey repairs or replacements.

Maintaining your solar energy system’s effectiveness and lifetime requires routine solar panel cleaning. It’s an easy task that will save you money in the long term and lessen your carbon footprint.

  • Ladder or scaffolding (if needed)
  • Hose with a spray nozzle (for automated cleaning systems)

2. Safety Precautions

Following basic safety measures before cleaning your solar panels is crucial to prevent accidents or injuries. 

  • Turn off your solar energy system to avoid electric shock.
  • Wear appropriate safety gear, such as gloves and non-slip shoes.
  • Use a stable ladder or scaffolding to access your panels.
  • Never use abrasive materials, such as steel wool or harsh chemicals, to clean your panels.

3. Do’s and Don’ts of Solar Panel Cleaning

When cleaning your solar panels, bear the following dos and don’ts in mind:

  • Do clean your solar panels regularly to maintain their efficiency.
  • Do use soft-bristled brushes or sponges to avoid scratching your panels.
  • Don’t use abrasive materials like steel wool or harsh chemicals to clean your panels.
  • Don’t use hot water on your panels, as it can damage them.
  • Don’t use high-pressure water or power washers; they can damage your panels.

Step-by-Step Process to Clean Your Solar Panels

Maintaining the effectiveness of solar panels and ensuring they continue producing electricity at their maximum capacity require regular cleaning. The following is a step-by-step guide for cleaning solar panels:

Step 1: Safety First

Taking extra precautions is essential if you have to install solar panels on your roof. Climbing a ladder can be dangerous if you need to gain experience. Consider hiring professional solar panel cleaners with the equipment and expertise to clean your solar panels safely.

In addition, wearing protective clothing such as gloves and eye protection can help prevent any accidents. Solar panels can get very hot when exposed to sunlight, so it’s essential to take precautions to avoid thermal shocks. By prioritizing safety, you can prevent accidents and ensure your solar panel cleaning is complete with effectiveness and efficiency.

Step 2: Switch off the System

Turning off the inverter and solar panel system is crucial when cleaning solar panels. This procedure ensures no electricity runs through the design as you wash it, lowering the possibility of an electrical shock or other harm.

In addition, shutting down the system stops the solar panels from producing electricity, which can obstruct cleaning. You may ensure that the solar panels are not producing electricity while you clean them by turning off the inverter. Once you have finished cleaning the solar panels, you can turn the system back on and resume generating clean, renewable energy.

Step 3: Remove Debris

An essential part of cleaning is clearing the solar panels of trash. Any accumulated dirt, dust, or other material can easily remove without harming the panel’s surface using a soft-bristled brush, such as a long-handled squeegee or a specialist solar panel cleaning brush. To avoid re-cleaning already-cleaned surfaces with dirt or debris, start at the top and work your way down.

Step 4: Solution to Clean

Preparing a solar panel cleaning solution is essential in cleaning solar panels. To make a cleaning solution, mix a few drops of mild soap, such as dish soap, with warm distilled or deionized water in a bucket. It helps to avoid any mineral deposits that can interfere with the panel’s efficiency. 

Using a mild soap solution is recommended, as harsh chemicals can damage the panel’s surface or leave behind residue that reduces its efficiency. Once the solution is mixed, apply the cleaning solution to the solar panel’s surface using a soft cloth or sponge. Let the solution sit on the panel for a few minutes, ensuring it does not dry up.

Step 5: Rinse with Water

One of the essential steps in the cleaning procedure is to rinse the solar panels with clean water. This procedure aids in cleaning the panels of any lingering dirt. You can start cleaning solar panels with pressure washer or hose to rinse them but use low water pressure to protect them. The panel’s efficiency may get lower by scratches or fissures on its surface brought on by high water pressure.

Additionally, ensure the water is warm because cold water might damage the panels by causing thermal shocks. Warm water rinsing can help protect the panels from harm and ensure they are clean and ready to produce sustainable energy.

Step 5: Dry the Panels

An essential part of cleaning is drying the solar panels. Use a squeegee or a soft, clean towel to dry the panel’s surface after rinsing it with clean water. It helps to eliminate any last bits of water and keeps the panels from getting watermarks.

Make sure the panel surface is completely dry before drying it. Water droplets can decrease the panel’s effectiveness by preventing sunlight from reaching the solar cells. Additionally, any lingering dirt scum or particles can impair the panel’s operation. You can ensure the solar panels are operating at their best and producing the cleanest energy by ensuring they are fully dry.

Step 6: Turn the System Back On

Turning the system on the inverter is the last stage in the solar panel cleaning procedure. After ensuring the panels are dry, you can restart the solar panel system to resume producing sustainable energy.

The system is turned on and converted from DC electricity produced by the solar panels into AC electricity that powers your home by turning on the inverter. You can use your solar panels to their fullest potential and enjoy clean energy’s advantages by turning the system on. To ensure the longevity and effectiveness of your solar panels, keep an eye on them frequently and clean them as necessary.


In conclusion, it is essential to regularly clean your solar panel system to retain its ability and provide clean energy for your home. You can maintain your solar panels in top condition, increase their efficiency, and lengthen their lifespan according to the step-by-step procedure described in this article.

Remember to put safety first, turn the system off, clear the area, rinse and dry the panels, and then turn it back on. By doing this, you can ensure that your solar panels are producing electricity for your house that is clean and renewable at their peak efficiency. However, you can also purchase solar panel cleaning kits to help you with effective cleaning. 

Additionally, cleaning your solar panels is an economical and eco-friendly approach to cutting costs and lowering your carbon impact. You can benefit from sustainable and clean energy by spending a little time and effort maintaining your solar panels.
