Hailstorms pose significant challenges to solar installations, often leading to physical damage and reduced efficiency. Recognizing this, AESOLAR has developed the Alpine Series to set new benchmarks in hail resistance. These modules feature 3.2mm tempered safety glass, enabling them to endure hailstones up to 40mm in diameter traveling at speeds of 27.54 meters per second. This capability significantly surpasses the International Electrotechnical Commission (IEC) standard, which requires modules to withstand 25mm hailstones at 23 meters per second.
Rigorous Testing and Certification
The Alpine Series has undergone stringent testing to validate its resilience. In a rigorous Swiss Hail VKF Standard HW4 Test conducted at TÜV Rheinland's Cologne Laboratory in Germany, the modules were subjected to impacts from 40mm hailstones, each delivering no less than 11.1 joules of energy, repeated 16 times. The results were remarkable:
- No visible damage: Post-test inspections revealed no physical defects.
- Integrity maintained: EL tests detected no micro-cracks.
- Consistent performance: No measurable power degradation.
- Electrical safety: The modules passed insulation resistance and wet leakage current tests.
These outcomes confirm the Alpine Series' exceptional ability to withstand severe hailstorms without compromising performance or safety.

Advanced Engineering and Materials
Beyond its hail resistance, the Alpine Series incorporates advanced T6 high-strength anodized aluminum alloy frames, the modules maintain structural integrity under harsh environmental conditions. Such advanced materials and engineering to ensure long-term durability and contribute to a product that not only meets but exceeds industry standards for durability and performance.
