Cleanliness, safety and efficiency for roof, system and operation.
Spring is here, bringing with it pollen, dirt, leaves, and the remnants of winter. With NIS's spring check, you can ensure your roofs, solar panels, and advertising systems start the new season clean, safe, and ready for use. We'll show you six key services that allow you to act proactively and prevent costly damage. These include cleaning photovoltaic systems and advertising signs, green roof maintenance, solar panel inspection (including visual and mechanical assessment), precise leak detection and tightness testing, and roof safety inspections.
Cleaning of PV systems
Maximum performance through clean modules: Dirt, dust, leaves, and bird droppings reduce the energy yield of your photovoltaic system by up to 20%. With our professional PV cleaning, you get full performance while simultaneously protecting the surface of your modules. We clean using environmentally friendly methods, demineralized water, and special soft brush systems, ideal for industrial buildings, flat roofs, and open areas. We ensure the optimal performance of your solar modules.
Cleaning of advertising signs on the roof or at height
Your outdoor advertising needs to be visible, clean, and eye-catching, especially in spring when pollen, dust, and weather residue soil surfaces. Professional cleaning of your advertising signs, illuminated signs, and building lettering ensures your message is clearly perceived again. We'll restore your advertising spaces to a high-gloss shine – safely at height.
Green roof maintenance
After autumn and winter, your green roof also needs attention. With professional spring maintenance, we remove leaves, unwanted vegetation, and winter debris, check drainage systems, and inspect the condition of the vegetation layer as well as critical edges and connections. This ensures your green roof remains functional, well-maintained, and retains its value in the long term. We support you in the care and maintenance of your green roof.
PV testing (including optical and mechanical assessment)
To ensure your photovoltaic system remains safe and efficient over the long term, we carefully inspect all visible components. Our PV inspection includes visual and mechanical checks of module surfaces, mountings, substructure, string wiring, cabling, cable routes, and distribution boxes. This allows us to detect damage, soiling, or loose connections early on, ensuring the availability, structural integrity, and efficiency of your system. We inspect your PV system reliably and professionally.ell.
Leakage testing/leak detection
Optimize your roofs after autumn and winter before spring rains exacerbate existing weaknesses. Using our certified, non-destructive testing technology (HV-SLD), we precisely locate moisture ingress. We would be happy to send you a quote for leak detection.
Safety inspection on the roof
Working at heights carries risks, especially at the start of the maintenance and cleaning season. With our inspection and audit service for fall protection and operator responsibility, we ensure that your roof area complies with regulations and is safe to operate. We inspect your roof for safety – quickly and professionally.
