However, it is important to choose a dish soap that does not contain any additives, such as moisturizers or scents, as these can leave a residue on the panels.
- Car Wash Soap – Car wash soap is another option for cleaning solar panels. It is designed to be gentle on car paint, so it is also safe for solar panels. However, like with dish soap, it is important to choose a car wash soap that does not contain any additives.
- Specialized Solar Panel Soap – Some companies make specialized soap specifically for cleaning solar panels. These soaps are designed to be gentle on the panels and to remove dirt and grime without leaving a residue. There are more details below, but two products worth checking out are Glass Gleam Solar and One Shot Solar Panel Cleaner.
Regardless of the type of soap chosen, it is important to dilute it properly before using it to clean the panels. Using too much soap can leave a residue on the panels, which can reduce their efficiency.
How To Clean Solar Panels With Soap
Cleaning solar panels with soap is a simple and effective way to ensure that they are operating at their maximum efficiency. Here are the steps to follow:
- Choose the Right Soap – It is important to choose a soap that is gentle and won’t damage the solar panels. Avoid using harsh chemicals or abrasives that can scratch or corrode the surface of the panels. A mild dish soap or a specialized solar panel cleaning solution can be used.
- Mix the Soap Solution – Mix the soap with warm water in a bucket or spray bottle. The ratio of soap to water should be about 1:10. Be sure to mix the solution thoroughly.

- Dry the Panels – Use a soft, clean cloth or squeegee to dry the panels. Be sure to remove all water droplets from the surface of the panels to prevent water spots.
Cleaning solar panels with soap is a simple and effective way to keep them operating at peak efficiency. By following these steps, you can ensure that your solar panels are clean and free from dirt, dust, and debris.
Factors To Consider When Choosing Soap For Cleaning Solar Panels
When it comes to cleaning solar panels, using the right soap is crucial. Here are some factors to consider when choosing the soap:
- Chemical Composition – The soap should be free from harsh chemicals that can damage the solar panels. Avoid using detergents, abrasive cleaners, or any soap that contains ammonia, bleach, or vinegar.
- pH Level – The soap should have a neutral pH level, ideally between 6 and 8. This will prevent any damage to the panels or the anti-reflective coating.
- Biodegradability – Choose a soap that is biodegradable and eco-friendly. This will ensure that the soap does not harm the environment or the panels.

Precautions To Take When Cleaning Solar Panels
While cleaning solar panels is a necessary task to maintain their efficiency, it is important to take certain precautions to ensure that the panels are not damaged during the cleaning process. Here are some precautions to keep in mind:
- Turn Off the System – Before starting to clean the solar panels, it is important to turn off the system to avoid any electrical hazards. This can be done by shutting off the circuit breaker or disconnecting the panels from the inverter.
- Use Soft Materials – When cleaning the panels, it is important to use soft materials such as microfiber cloths or sponges to avoid scratching the surface of the panels. Avoid using abrasive materials such as steel wool or brushes with hard bristles. One product I recommend is a cleaning brush with extendable handle, such as the Happybuy Water Fed Pole Kit. This type of poll keeps a constant flow of water and also helps keep you safely on the ground.
- Avoid Harsh Chemicals – While it may be tempting to use strong chemicals such as ammonia or bleach to clean the panels, it is important to avoid them as they can damage the surface of the panels. Instead, use mild soap and water or a specialized solar panel cleaner.
- Be Careful on the Roof – If the solar panels are located on the roof, it is important to take extra precautions to avoid falls or injuries. Wear slip-resistant shoes and use a stable ladder or scaffolding to access the panels.
- Check for Damage – Before cleaning the panels, it is important to check for any damage such as cracks or chips. If any damage is found, it is best to contact a professional to repair or replace the panels.
By taking these precautions, you can ensure that your solar panels are cleaned effectively without causing any damage or hazards.
Why Clean Solar Panels Are Important
Solar panels are a popular choice for generating electricity from renewable sources. They are designed to capture sunlight and convert it into electrical energy. However, over time, solar panels can become dirty and covered with debris, reducing their efficiency and output. This is why it is important to keep solar panels clean.
Dirty solar panels can reduce the amount of sunlight that reaches the solar cells, which in turn reduces the amount of electricity that is generated. In fact, studies have shown that dirty solar panels can reduce the efficiency of a solar panel system by up to 30%. This means that if you have dirty solar panels, you could be losing out on a significant amount of electricity, which can cost you money in the long run.
Cleaning your solar panels can also help to extend their lifespan. Dirt, dust, and debris can accumulate on the surface of the solar panels, which can cause abrasions and scratches. Over time, these scratches can damage the solar cells and reduce their lifespan. By keeping your solar panels clean, you can help to prevent this damage and extend the life of your solar panel system.

I recently used Glass Gleam Solar to clean my solar panels and was impressed with how little product I needed to use. The concentrated formula goes a long way, which makes it a great value for the price. I also appreciate that it’s easy on my hands and has a low fragrance.
However, I did notice that it didn’t completely remove some mineral deposits on the edges of my panels. Additionally, while it did leave my panels looking clean, it didn’t provide the glossy finish I was hoping for.
Finally, I haven’t noticed a significant difference in dust accumulation since using this product, so I’m not sure if it truly repels dust as advertised.
| PROS | CONS |
| Very concentrated formula goes a long way | May not remove mineral deposits |
| Leaves no spots or residues | Does not provide a glossy finish |
| Easy on your hands | May not repel dust as advertised |
Overall, I would recommend Glass Gleam Solar for its effectiveness in cleaning solar panels and its concentrated formula, but keep in mind that it may not remove all mineral deposits and won’t provide a glossy finish.
Happybuy Water Fed Pole Kit
If you’re looking for a reliable and easy-to-use tool to clean solar panels, the Happybuy Water Fed Pole Kit is a great option.
I recently used the Happybuy Water Fed Pole Kit to clean my solar panels, and I was impressed with its performance. The 30ft telescopic pole allowed me to reach all areas of the panels without having to climb a ladder, and the aluminum construction made the pole lightweight and easy to handle. The angle-adjustable PP brush was soft enough to prevent scratches but tough enough to remove grime and dirt effectively.
One minor issue I encountered was that the pole sagged a little too much at full length when used from the ground, but this was easily remedied by adjusting the length of the pole. Additionally, the quick connect coupler was not included in the purchase, which was a bit of a disappointment. Finally, the pole got a bit unwieldy with the skinny first pole extended, but this was not a major issue.
| PROS | CONS |

The telescoping handle made it easy to reach high areas without the need for a ladder, and the soft bristles were gentle enough to use on delicate surfaces. The powerful water outlet also helped me save time and effort by quickly removing dirt and debris.
However, the on/off water switch can be a bit finicky, and the brush head is not very wide, so it may take longer to clean large surfaces. Additionally, the plastic threads on the brush head can be a bit fragile, so be careful not to overtighten the brush onto the pole.
