Cleaning solar panels in Antwerp

In and around Antwerp, solar panels suffer more than elsewhere in Flanders. Fine dust from the port area, industrial precipitation and salty sea air cause faster contamination, and thus yield loss. We clean your installation safely with osmosis water, without scratching and without you having to go up on the roof yourself.

Antwerp: a challenging environment for solar panels

With Europe's second largest port and an extensive petrochemical cluster, Antwerp is among the most heavily polluted regions for photovoltaic installations in Belgium. The interplay of industrial precipitation, particulate matter and salty sea air means that panels here pollute noticeably faster than inland.

Local factors affecting returns

  • Industrial precipitation: soot, dust and chemical particles from the port and industrial area settle on the panel surface.
  • Particulate matter (PM2.5 and PM10): Antwerp is among the Flemish municipalities with the highest annual averages. The result is a thin, persistent film on the glass.
  • Salt and moisture: proximity to the Scheldt brings salty air that accelerates deposits and can leave marks.
  • Birds and pollen: gulls along the docks and pollen from lime and sycamore trees in spring leave localised stains.

What that means for your installation

Heavily soiled panels can produce up to 25% less yield. In an urban and industrial environment like Antwerp, we recommend thorough cleaning once or twice a year, adapted to the orientation and inclination of your roof. Installations near the Ring Road, port area or busy traffic axes deserve extra attention.

Getting solar panels professionally cleaned

Getting solar panels cleaned doesn't have to be complicated. You request a quote, we schedule a date, and our team does the rest - you don't even have to be there. Afterwards, you will receive a report with before and after photos. No hassles, no surprises, no additional costs.

Our 4-step approach

Thorough pre-inspection

Visual + thermographic check of your installation. We identify hotspots and damage before cleaning.

Robotic cleaning with osmosis water

Our certified cleaning robots operate on battery, without chemicals. Osmosis water dissolves all dirt and leaves no streaks or residue.

Quality control

After cleaning, we recheck each panel. You will receive a detailed report with before and after photos.

Aftercare and Advice

Based on your installation, environment and production data we draw up an optimal cleaning calendar.

Innovative cleaning robots

For large solar parks or extensive roof installations, Solarco deploys robot cleaners. These robots run on batteries and are certified by renowned module manufacturers. The robot can quickly and evenly clean large installations of solar panels without damaging the panels.

Benefits of professional solar panel cleaning in Antwerp

  • Higher efficiency: Several studies show that cleaning solar panels can provide an efficiency improvement of a few percent to as much as 15%, depending on the degree of contamination.
  • Longer lifespan: By preventing dirt build-up and hot spots, your entire system will last longer.
  • Safety and warranty: Many manufacturers recommend professional cleaning to maintain the warranty. Climbing a roof yourself is also not without risk.
  • Time savings: With the right tools and experience, we can take care of a large installation in a short time, while you yourself spend your precious time on other things.
  • Sustainable approach: Osmosis water and robotic cleaning minimise the use of harmful chemicals, which is better for the environment as well as for the panels themselves.

Frequently asked questions about solar panel cleaning Antwerp

Due to the high particulate load and industrial precipitation, we recommend one to two cleanings per year in greater Antwerp. Closer to the port or along busy traffic axes, a second cleaning can quickly pay for itself.
Rain removes loose dust, but leaves behind a thin mineral and soot film. Especially in an industrial environment like Antwerp, this layer cakes and visibly reduces light output.
Yes. We clean private roofs as well as large company installations in the port area, on logistics parks and in the petrochemical cluster. Thanks to our cleaning robots, we process installations with thousands of modules in a short turnaround time.
Depending on contamination levels, customers in Antwerp typically see between 10 and 25% yield recovery immediately after cleaning. We measure or estimate the gain with you based on your monitoring data.
We work throughout greater Antwerp, including in Berchem, Borgerhout, Deurne, Merksem, Ekeren, Hoboken and Wilrijk, and in surrounding municipalities such as Mortsel, Edegem, Schoten, Brasschaat, Kapellen and Stabroek.
