We believe clean and well-maintained solar installations are essential for maximizing energy yield and protecting long-term investments. Our team of trained specialists uses gentle, chemical-free methods and modern technology to ensure every system we service operates efficiently and safely. We take pride in treating each installation as if it were our own, offering transparent advice and consistent results that our customers can depend on year after year.

As members of Swissolar and the Swiss Solar Energy Association, we stay closely connected to industry standards and best practices. Whether you own a residential rooftop system or a large commercial array, we provide the professional care needed to extend system life, boost output, and support Switzerland’s transition to sustainable energy.

We approach every photovoltaic system with careful planning so that maintenance and cleaning deliver the greatest possible benefit. Before any work begins, we conduct a thorough on-site assessment of the installation, examining module types, roof design, accessibility, and local environmental conditions. This allows us to create a tailored service plan that matches the unique requirements of each system.

Our planning process considers factors such as soiling patterns, regional weather influences, and performance goals. We evaluate whether manual cleaning, robotic solutions, or a combination of methods will achieve the best results, and we advise on optimal service intervals. By investing time in proper planning, we help our clients avoid unnecessary costs and ensure every intervention improves efficiency and protects the modules.

We remain manufacturer-independent and transparent throughout the planning stage. Our recommendations focus solely on what will genuinely enhance the performance and longevity of the photovoltaic system. Clients receive clear explanations of the proposed approach, expected outcomes, and associated costs, so they can make informed decisions with complete confidence.

We specialize in the efficient and gentle cleaning of large-scale photovoltaic installations using advanced robotic technology and pure osmosis water. For extensive commercial or industrial systems, our cleaning robots navigate complex layouts safely and thoroughly, removing dirt, pollen, bird droppings, and industrial residue without damaging sensitive module surfaces.

Our chemical-free process relies on demineralized water produced on site, which leaves no residues and prevents the formation of water spots or mineral deposits. Combined with specialized brush systems, this method restores light transmission and can recover significant energy losses—often up to 30 percent in heavily soiled arrays. We adapt our techniques to the specific height, inclination, and exposure of each large-scale system to guarantee consistent results.

Safety and precision remain central to our large-scale cleaning operations. Our trained teams work with certified equipment and follow strict protocols for working at height. After cleaning, we provide documentation of the work performed so system owners can track improvements in performance and plan future maintenance with clarity.

We deliver comprehensive solar panel maintenance services throughout Switzerland, helping owners protect their investments and maintain maximum energy production. Our full-service offering includes professional cleaning, visual inspections, performance measurements, thermographic checks, and ongoing monitoring tailored to local Swiss conditions—from alpine regions to urban and industrial environments.

Regular maintenance prevents the gradual buildup of soiling that reduces output and shortens module lifespan. We recommend service intervals based on location and exposure, typically every two to three years, with more frequent attention in areas affected by heavy dust, agriculture, or industry. Our nationwide teams ensure flexible scheduling and consistent quality no matter where the system is located.

By choosing our Switzerland-wide maintenance service, clients benefit from a single reliable partner who combines technical expertise with personal care. We focus on extending system life, maximizing returns, and supporting the reliable generation of clean energy across the country.
