Avoiding Hail Damage on Solar Panels from The Start

Hail damage is a significant concern for solar panel owners, especially in storm-prone regions. Choosing the right panels and taking proactive measures can prevent costly damages and ensure efficient energy production year-round.

Choose Solar Panels With High Hail Ratings

Most monocrystalline and polycrystalline solar panels withstand hailstones up to 25 millimeters (0.98 inches) in diameter falling at 50 miles per hour. However, flexible thin film panels offer less resistance due to their construction.

Authorities like Underwriters’ Laboratories (UL) and the International Electrotechnical Commission (IEC) have established hail ratings based on rigorous impact tests. For businesses in hail-prone areas, look for panels rated under UL 61730 or IEC 61730. These certifications indicate panels can handle hailstones ranging from 1 to 3 inches in diameter at speeds of up to 88 miles per hour. Larger, faster hailstones are rare but possible.

Panels in North America mostly have UL certifications, while IEC is common globally. Some panels may carry both markings, further ensuring their durability. Look also for an IP68 rating, denoting that the panel is waterproof and dustproof, which further extends its life and reliability.

UL 61730 Rated Panels

UL 61730 rated panels undergo extensive testing to ensure they can endure severe weather conditions, including large, fast-moving hailstones. This certification is important for safeguarding your investment in settings prone to frequent storms.

IEC 61730 Rated Panels

IEC 61730 rated panels meet international standards for hail resistance, making them a reliable choice for installations worldwide. For regions outside North America, choosing an IEC 61730 rated panel can ensure your solar panels withstand harsh weather conditions.

Covering Your Investment with Methacrylate

If you want additional protection, consider temporary covers for your solar panels. Both hard-shell and padded fabric covers are available, offering an extra layer of defense against hail. However, these covers must be manually placed before a storm and removed afterward, which can be cumbersome and impractical, especially for larger installations.

Time spent covering panels means time lost generating electricity, creating a trade-off between protection and productivity. For smaller installations, temporary covers may be viable, but for larger commercial setups, the logistics and risks involved, such as having a team on the roof during approaching storms, make it less feasible. With UL 61730 and IEC 61730 certifications, the need for such covers reduces significantly, allowing you to focus on energy production without constant concern over hail damage.

Installation Best Practices for Hail Protection

Protecting solar panels from hail starts with smart installation strategies. Implementing best practices ensures durability and efficiency.

Correct Tilt

Installing solar panels at the right angle minimizes hail impact. A steeper tilt can deflect hailstones. For example, panels set at a 30-45 degree angle generally handle hail better than those set flat. This angle directs hail to glide off rather than hit directly. Research from the Solar Energy Industries Association (SEIA) shows panels with optimal tilt angles suffer fewer damages, making it a key consideration.

Appropriate Azimuth

Positioning panels to avoid prevailing hailstorm paths reduces damage likelihood. If you know from local weather patterns that hail generally comes from the north, adjust the azimuth so panels face slightly away from that direction. This change doesn’t compromise energy production but offers added protection. The National Renewable Energy Laboratory (NREL) notes that this tactic can improve panel longevity in hail-prone areas.

Strong Racking Systems Choices

Choosing impact-resistant mounts and racks is essential. High-quality racking systems absorb hail impacts, reducing breakage risk. Brands like IronRidge and Unirac offer racking solutions tested against extreme weather conditions, including hail. Their products are designed to withstand impacts, ensuring solar panels remain intact. The American Society for Testing and Materials (ASTM) provides ratings showing these systems’ resilience under severe hail conditions.

Roof Penetration Protection Is Critical

Securing roof penetrations prevents water and moisture damage, preserving panel integrity. Use sealing products rated for extreme weather to protect roof and panel connections. Ensuring penetrations are correctly sealed avoids water-related panel failures. The International Association of Certified Home Inspectors (InterNACHI) emphasizes properly sealed roof penetrations as a critical factor in preventing leaks and extending the lifespan of solar panel installations.
