Here’s How to Protect Your Property and Power It Too!
Alberta, particularly Calgary, is no stranger to severe hailstorms. In August 2024, a catastrophic hailstorm struck the region, causing nearly $2.8 billion in insured losses, making it the second-costliest insured event in Canada’s history. Some hailstones were as large as chicken eggs, wreaking havoc on homes, vehicles, and businesses.
Though hail can form anywhere that experiences thunderstorms, the National Oceanic and Atmospheric Administration’s (NOAA) hail climatology maps of the continental US reveal a distinct “hail alley” that extends from West Texas in the south up through the Dakotas in the north. Viewed from this regional perspective, severe hail risk exists for most US project locations east of the Rockies.
One solution gaining popularity is solar carports—a dual-purpose structure that not only shelters vehicles from damaging hail but also generates clean, renewable energy.
How Solar Carports Protect Against Hail Damage
Yes, a solar carport can provide protection against hail damage, but the level of protection depends on several factors:
Panel Durability
- Most solar panels are designed to withstand hailstones up to 1 inch (25 mm) in diameter traveling at speeds of around 50 mph.
- Some high-quality panels are rated for even larger hailstones and higher impact resistance.
Carport Design
- A well-built solar carport with a strong frame and proper tilt can help deflect hail impact.
- If panels are installed at an optimal angle (30–40 degrees), hailstones are more likely to glance off instead of hitting directly.
Panel Coverings
- Some installations include protective overlays or hail-resistant films to enhance durability.
Hail Severity
- While solar carports can protect against most hailstorms, extremely large hail (e.g., baseball-sized) could still cause damage to both the panels and vehicles underneath.
Insurance Considerations
- If you live in a hail-prone area, check if your solar panels and vehicles are covered under insurance for hail damage.
Hail-Resistant Solar Panels & Carport Enhancements
If hail protection is a priority for your solar carport, here are some key recommendations:
Hail-Resistant Solar Panels
- Panels with High Impact Resistance: Look for panels that are IEC 61215 & UL 61730 certified, meaning they’ve passed strict hail impact tests. Some are tested against hailstones up to 2 inches in diameter at 88 mph.
- Thicker Tempered Glass: Panels with 3.2mm or thicker glass offer better protection, and dual-glass (glass-on-glass) panels tend to resist cracking.
- Panel Backing & Frame Strength: A sturdy aluminum frame and reinforced backing help panels withstand hail and strong winds.
Solar Carport Design Enhancements
- Tilt Angle Optimization: A steeper panel angle helps deflect hail instead of taking direct hits.
- Protective Coverings & Coatings: Adding a polycarbonate shield or hail-resistant film over panels provides an extra layer of protection.
- Reinforced Racking & Mounting System: A stronger racking system with additional bracing reduces panel movement during storms.
Other Smart Solar Racking Solutions
Hail Sensors & Early Warning Systems: Other solar racking systems, like single axis trackers, can include systems that can monitor weather conditions and send alerts before a hailstorm, allowing panels to reposition to minimize impact.
