Solar panel cleaning

For consistently optimal performance

Clean solar panels ensure maximum and long-lasting energy production. Over time, dust, pollen, and airborne deposits accumulate on the surface and reduce efficiency. Neteco provides professional cleaning services tailored to every installation, helping to maintain performance and ensure optimal operation.

Solar panel cleaning:
a key factor in performance

Your solar panels are constantly exposed to weather conditions, pollution, and natural deposits. Professional cleaning offers many benefits:

Optimized efficiency

Even invisible deposits can reduce the panels’ ability to capture sunlight. Regular cleaning helps maintain maximum energy production.

Consistent energy production

Without maintenance, performance gradually declines. Regular cleaning ensures stable output throughout the year.

Extended lifespan

The accumulation of dirt and debris can eventually affect surfaces and components. Proper maintenance helps preserve the integrity of your installation.

Protecting your investment

Well-maintained solar panels operate more efficiently and allow you to maximize the return on your photovoltaic installation.

An eco-friendly and effective cleaning method

For solar panel cleaning, Neteco uses a pure water cleaning system without chemicals, ensuring spotless results without streaks. This method is gentle on surfaces while delivering excellent cleaning performance, regardless of the type of installation.

Solutions tailored to every situation

Depending on the configuration, cleaning is carried out using specialized robotic systems for large installations or manually with soft rotating brushes for more sensitive areas. All work is performed safely using suitable equipment such as aerial platforms, for both residential and commercial clients.

Measurable results, visible immediately

According to several studies within the photovoltaic industry, dirty solar panels can lose between 5% and 20% of their efficiency, or even more in exposed environments such as dusty, polluted, or agricultural areas. Professional cleaning helps restore performance close to original production levels, with measurable gains visible immediately after cleaning.

You have questions,
we have answers.

Does the system need to be turned off during cleaning?

No. In most cases, it is not necessary to shut down the installation during the cleaning process.

How often should solar panels be cleaned?

In general, cleaning once or twice a year is recommended. The frequency may vary depending on the environment, nearby trees, pollution levels, agricultural activity, or dust exposure.

Does rain clean solar panels automatically?

No. While rain removes some dirt, it often leaves behind residues, marks, and fine deposits that continue to reduce performance.

Is there a risk of damaging solar panels during cleaning?

No, provided that appropriate cleaning methods are used. Pure water and soft brushes allow effective cleaning without damaging the surfaces or components.

Is solar panel cleaning worth it?

Yes, in most cases. The performance gains, which can reach several percentage points, often offset the cost of the service in a relatively short time.

Do you also work for homeowners?

Yes. Neteco provides services for both private and commercial clients. Individual homes, residential buildings, industrial facilities, commercial properties, and agricultural sites all benefit from cleaning solutions tailored to their specific installations.
