The Alpine Series has undergone and passed the rigorous Swiss Hail VKF HW4 Test, performed at the TÜV Rheinland Cologne Laboratory in Germany. This test subjects the module to extreme impacts: 40mm hailstones, producing over 11.1J of energy, impacting the module at 16 different points. Verified Results: No visible damage to the module No micro-cracks detected in the Electroluminescence (EL) test No power degradation Passed insulation resistance and wet leakage current tests

The Alpine Series proudly holds the Swiss Hail VKF HW4 Level Certification, a testament to its exceptional resilience. Certified by TÜV Rheinland, a globally trusted testing institution, this certification guarantees adherence to the highest industry standards.

With its 6005-T6 high-strength anodized aluminum alloy frame, the Alpine Series withstands wind loads up to 3600Pa — equivalent to wind speeds of 171.33 mph (275.73 km/h). This is critical as hailstorms are often accompanied by winds exceeding 120 mph (193.12 km/h).

As climate change intensifies, out-of-season weather events become more frequent, increasing risks for solar developers, EPCs & homeowners. The Alpine Series is built for hail-prone areas, minimizing damage and financial losses with superior resistance to force majeure and hail impact.
