HIGH DURABILITY OF THE SOLROOF SYSTEM

What Does this Mean for SOLROOF Customers?

Hail resistance – The SOLROOF roof effectively protects your home from hail! In a specialized test, the modules were subjected to impacts from ice balls up to 25 mm in diameter, fired at a speed of 23 m/s (83 km/h).

Moisture and condensation resistance – SOLROOF passed a crucial endurance test, confirming resistance to prolonged exposure to high temperature and humidity: 1000 hours at 85°C with 85% relative humidity.

Overheating resistance – SOLROOF passed the durability test for hot spots, which are local overheating and self-ignition points that can affect the module’s lifespan and safety.

Extreme temperature resistance – SOLROOF panels successfully completed 200 test cycles in extreme temperature conditions from -40°C to 85°C, in accordance with IEC 61215 standard.

Ice resistance – The panels underwent a demanding test involving 10 cycles of varying temperatures from -40°C to 85°C at high humidity (85%).

The panel tests were conducted by the renowned Fraunhofer Institute for Solar Energy Systems ISE – part of Fraunhofer-Gesellschaft, Europe’s largest independent research institution. The organization specializes in advanced testing of modern technologies, with particular focus on the photovoltaic sector. Fraunhofer-Gesellschaft comprises 66 German research institutes, establishing itself as an authority in energy innovation.

Self-ignition is most Commonly Caused by:

❌ Incorrectly routed cables – including routing cables where they are exposed to friction or crushing, or improper installation (loose, without proper fastening, or without additional UV protection).

❌ Too many parallel connections with cables of insufficient cross-sections – this design flaw can lead to cable overload and ultimately ignition.

❌ Lack of grounding – equipotential bonding improves the safety of photovoltaic installations in terms of potential surges, shock risks, and electrical discharges. Unfortunately, many installers completely overlook this aspect.

❌ Mounting components on flammable materials – both photovoltaic panels and devices such as inverters can reach very high temperatures during operation.
