Solar panel cleaning - Termolat

Solar panel cleaning

Dirty solar panels = up to 30% lower electricity production. Dust, pollen, emissions and bird droppings reduce the efficiency of solar panels and accelerate their wear and tear.
A European-wide study shows that the average energy loss due to a layer of dirt in Europe is 5.3%, reaching 14% in Spain and dropping to 2% in Norway. This study took into account that rain cleans approximately 10% of dirt. In dry and dusty areas, energy losses are much higher, ranging from 15% to 30%.
Taking the average European figure of 5.3% energy loss as an example, this amounts to at least EUR 5,000 in financial losses per year for a medium-sized solar park (1 MW).
That is why we offer a solution that combines efficiency, safety and modern technologies.

We offer professional solar panel and solar park cleaning using drone technology and the specialized eco-friendly solution Vitapanel Clean ECO.

Our drone-based method enables fast, consistent, and safe application of the cleaning agent, even in hard-to-reach or large-scale areas.

 

Advantages

Drone Technology

  • Minimal risk of panel damage (no direct physical contact);
  • No need for heavy equipment or personnel climbing on panels;
  • Fast and uniform application, even across large solar parks.

 

Vitapanel Clean ECO – Safe and Effective

  • Eco-friendly and biodegradable solution;
  • Gentle on panel surfaces, protecting them from micro-damage;
  • Leaves no residue that could reduce solar transmission.

 

Efficiency Restoration

  • Up to 5–30% increase in energy output;
  • Reduced long-term maintenance and replacement costs.

 

Why Regular Solar Panel Cleaning Matters

  • Dirt and debris block sunlight, reducing panel efficiency;
  • Bird droppings contain acids that can damage the protective surface layer;
  • Industrial and agricultural dust builds up quickly, especially in summer;
  • Regular cleaning extends the panels' lifespan and helps maintain warranty conditions.

 

Our Process

  • We coordinate with the client in advance to:
    • Confirm the exact location of the site;
    • Check for drone flight authorization in the specific area.
  • We then:
    • Assess the site remotely or on location;
    • Plan the cleaning strategy based on weather, surroundings, and surface conditions;
    • Apply the cleaning solution via drone;
    • Provide rinsing with demineralized water, if required.
