Solar Clean

What Solar Clean does

Solar Clean is a Belgian private limited company (Solar Clean bvba) founded in 2008 and headquartered in Zaventem, Belgium. The company provides professional solar panel cleaning, visual inspection, and reporting services for residential, agricultural, industrial rooftop, and ground-mounted photovoltaic installations. Over more than 15 years of operation, Solar Clean has accumulated experience cleaning in excess of 300 MW of rooftop installations and 450+ MWp of ground-mounted solar farms across Belgium, France, Germany, and the Netherlands, serving enterprise customers including ALDI, DHL, Nike, Recticel, and Kims Choc.

The core service uses chemical-free cleaning methods with a multi-technique approach: cleaning from ground level, from scaffolding, or using cherry picker equipment depending on site requirements. For utility-scale ground-mounted solar farms, Solar Clean operates a specialized machine park with autonomous cleaning capability. A complementary visual inspection service identifies panel damage, hot spots, loose structures, and other defects, producing detailed reports. An adjacent gutter and veranda cleaning service is offered in the Brabant region of Belgium, leveraging existing crews and equipment.

Solar Clean operates a professional services model with quote-based pricing tied to project size, complexity, and location. The go-to-market is field-based, supported by a multilingual website (Dutch, French, English, German), an extensive project-reference portfolio, and direct phone/email contact for quote requests. The company holds a research partnership with VITO (Flemish Institute for Technological Research), which produced empirical evidence on contamination and cleaning effectiveness in agricultural PV installations. Revenue is project-based and not publicly disclosed; the company has no external funding rounds or disclosed headcount.

Partnerships

Two partnerships are on record, tiered core and minor.

• VITO (Vlaamse Instelling voor Technologisch Onderzoek)coreStrategic or Co-development PartnerSolar Clean conducted practical research in partnership with VITO (Flemish Institute for Technological Research) on the efficiency gains from solar panel cleaning. The study monitored 10 agricultural PV installations before and after cleaning over a 3-month period, yielding clear results on contamination levels and cleaning benefits.
• TNO (Netherlands Organisation for Applied Scientific Research)minorStrategic or Co-development PartnerTNO conducted research on the relationship between panel inclination angle and contamination levels in the Netherlands. Their findings (4.4%-7.7% contamination after one year) are referenced by Solar Clean as part of their educational content on the importance of panel cleaning.

Regional players

• SC Clean: Swiss solar panel cleaning service provider focused on commercial rooftop and ground-mounted PV cleaning in Switzerland and neighboring regions. Comparable service-led model but operating in a different geography (Alpine Switzerland) than Solar Clean's Benelux/France/Germany footprint.

Broad incumbents

• Kärcher: German global leader in cleaning equipment that offers professional solar panel cleaning machines, telescoping brush systems, and purified-water solutions. Comparable as a broad incumbent in the same product category, though Kärcher's model is equipment sales plus dealer service networks rather than direct on-site cleaning.
• Borrego Solar (Maintenance & O&M): US-based solar EPC and O&M provider that offers preventive and corrective maintenance, including panel cleaning, for commercial and utility-scale PV. Comparable end-customer offering (solar O&M services) though broader in scope including asset management and monitoring.

Direct peers

• Ecoppia: Israel-based developer of autonomous waterless robotic cleaning systems for utility-scale solar farms, with deployments in MENA, India, Latin America, and the US. Competitor to Solar Clean in the ground-mounted solar farm cleaning segment, particularly for large MW-scale projects.
• Heliotex: US-based provider of automated solar panel cleaning systems and services using brush-and-water technology for commercial and utility-scale PV. Closely comparable service-led cleaning offering for industrial and ground-mounted segments.
• SolarCleano: Belgian-headquartered company that designs and sells robotic solar panel cleaning machines, including the Cleano and SolTarine lines, targeting utility-scale and commercial PV installations across Europe. Direct competitor to Solar Clean's ground-mounted and industrial rooftop cleaning services.
• SunBrush mobil: German manufacturer of truck- and tractor-mounted solar panel cleaning machines (SunBrush mobil) used on large ground-mounted solar farms across Europe. Direct competitor in machine-based cleaning for utility-scale installations, overlapping Solar Clean's ground-mounted service offering.
• Serbot: Switzerland-based manufacturer of the GEKKO Solar and other robotic solar panel cleaning robots used for utility-scale and large rooftop installations in Europe. Direct competitor in automated cleaning technology, overlapping with Solar Clean's industrial and ground-mounted service lines.

Emerging players

• GreenServ: Netherlands-based solar cleaning and maintenance service provider focused on Dutch commercial rooftops and small ground-mounted arrays. Comparable emerging service player in the same Benelux region, addressing residential-to-mid-scale industrial sites.

Others

• Solar Operations Solutions (SolarOps): European solar O&M software and services platform that helps asset owners schedule and manage maintenance including panel cleaning. Adjacent ecosystem participant that complements or competes with on-site cleaning providers like Solar Clean via digitized inspection and reporting.
