How To Clean Sunpower Solar Panels?


SunPower is a leading manufacturer of high-efficiency solar panels known for their exceptional performance and reliability.

SunPower solar panels are some of the most efficient and high-quality solar panels available.

However, regular maintenance and cleaning are necessary to ensure that the panels continue to operate at peak performance.

Dirt, dust, bird droppings, and other debris can accumulate on the surface of the panels and reduce their efficiency.

A dirty solar panel can lose up to 30% of its energy output, significantly impacting energy savings.

Cleaning SunPower solar panels is a relatively simple process that can be done using some basic tools and equipment.

However, following the right cleaning techniques is essential to avoid damaging the panels or causing any electrical hazards.

Importance Of Regular Cleaning For Sunpower Solar Panels

Solar panels are designed to be long-lasting, durable, and require minimal maintenance. However, regular cleaning of SunPower solar panels is recommended as dirt, dust, and debris accumulate on solar panels surfaces over time, reducing their efficiency and performance.

Despite being designed to last with minimal upkeep, regular cleaning of solar panels is essential to maximize energy production and lengthen their lifespan.

Dirt and debris on solar panel surfaces can obstruct sunlight from reaching the cells, reducing energy output.

This is particularly significant in areas with limited sunlight or during seasons with shorter daylight hours.

Regular cleaning of solar panels removes any buildup, enabling panels to capture maximum sunlight.

Over time, dust and debris can damage the surfaces of solar panels, leaving scratches or marks that further reduce their efficiency.

Regular cleaning prevents such damage, preserving their surfaces and efficiency.

Regular cleaning of solar panels also helps in preventing the growth of mould, mildew, and other organisms that can pose health hazards, especially in environments with high humidity or heavy rainfall.

Overall, cleaning SunPower solar panels regularly is crucial for maintaining their effectiveness, increasing lifespan, and ensuring maximum energy production.

Impact Of Location On Solar Panel Cleaning

The location of solar panels plays a significant role in determining the frequency and method of cleaning required to maintain their efficiency.

Generally, solar panels should be cleaned at least once or twice a year. However, some locations may require more frequent cleaning to maximize energy production.

Polluted Areas

Areas with high pollution levels, such as those near factories, highways, or airports, tend to experience a greater buildup of atmospheric grime and oil, requiring more frequent cleaning.

Wooded Areas

In wooded areas, leaves can accumulate on the panels, obstructing the absorption of sunlight. Trees can also attract birds that leave droppings on the panels, damaging their surface and reducing efficiency.


In dry and dusty climates, such as the Middle East and US Southwest, sand accumulates on PV panels, blocking light and scratching the surface.

Similarly, wildfire ash can quickly fall on panels in regions such as California or Australia.

The angle of the rooftop where the PV panels are installed also affects the cleaning frequency.

Step-By-Step Guide To Clean Sunpower Solar Panels

Cleaning SunPower solar panels is a simple process that can be done with a few basic materials. Here’s a step-by-step guide to cleaning SunPower solar panels:

Safety Precautions

Before cleaning your solar panels, take safety precautions to avoid accidents. Make sure to turn off the power supply to the solar panels and wear slip-resistant shoes to prevent falls.

Remove Loose Debris

It is recommended to use a soft-bristled brush to gently eliminate any loose debris from the solar panel surface.

Abrasive materials should be avoided as they can cause scratches and damage to the panel surface.

Prepare Soapy Water

Fill a bucket with warm water and add a few drops of dish soap. Mix the soap and water thoroughly.

Wash The Panels

Using a soft cloth or brush, dip it into the soapy water and gently clean the surface of the panels. Work in small sections, starting from the top of the panel and moving downwards.

Rinse The Panels

Once you have washed the panels, rinse them thoroughly with water. Use a hose or a bucket of clean water to rinse the panels.

Dry The Panels

Use a squeegee or soft cloth to dry the surface of the panels. Make sure to remove any excess water to prevent water spots from forming on the surface of the panels.

Inspect Panels

Inspect the panels for any scratches or damage after cleaning. If you find any damages, consult a professional to have them repaired.

By following these simple steps, you can keep your SunPower solar panels clean and ensure optimal energy production.

Is It Advisable To Clean Your Solar Panels?

Yes, you should clean your solar panels. Cleaning your solar panels periodically is similar to washing your car to prevent rusting, ensuring they operate efficiently.

Solar panels are located outside, causing pollen, dust, and grime to accumulate on their surface, reducing their efficiency by 15-25%.

This means you will consume 15-25% more electricity from your power provider, leading to higher monthly bills.

A Google study conducted at their Mountain View, CA solar farm demonstrates how effectively cleaning your panels can be.

The study revealed that when panels were cleaned, their electricity output doubled, and their efficiency increased by 12%.

Cleaning solar panels is as easy as cleaning windows and can be done in the same amount of time. By cleaning solar panels, you will increase your savings and reduce expenses.

Is It Safe To Clean Solar Panels With Water?

Non-heated, potable water with normal pressure is the safest option for cleaning solar panels. You can also use over-the-counter glass cleaners like Windex, equivalent solution, or 3% soap-and-water solution to remove dirt and grime.

However, avoid using hard or mineral-rich water as it can damage the panels over time.

If there is stubborn grime or dirt build-up on the panels, a pressurized water spray of up to 1,500 psi may be used.

This pressure is sufficient to remove dirt without damaging the panels.

It is important to follow the manufacturer’s guidelines when cleaning your solar panels.

Cleaning solar panels with water is safe if you use non-heated, potable water with normal pressure and avoid using hard or mineral-rich water.
