Quick Answer
Many people believe that solar panels are completely immune to hail damage, while others assume that all solar panels are equipped with built-in hail protection. However, the reality is that solar panels can be damaged by hail, but not always, and not all panels have built-in protection.
Common Misconceptions
One common misconception is that all solar panels are rated for hail impact. While some panels may meet specific hail standards, not all do. For example, the International Electrotechnical Commission (IEC) has a hail impact test that simulates a 0.75-inch (19mm) diameter hailstone at 50 mph (80 kph). However, even if a panel meets this standard, it may not be enough to protect it from larger hailstones.
Hail Impact and Panel Type
Another misconception is that all solar panels are equally susceptible to hail damage. In reality, different types of panels can withstand hail impacts better than others. For example, panels with a tempered glass top surface may perform better than those with a laminated glass top surface. Additionally, panels with a higher glass thickness may be more resistant to hail impact than those with a lower thickness.
Installing Hail Protection
While some solar panels may come equipped with built-in hail protection, such as a hail-resistant glass surface or a reinforced frame, it’s often possible to add additional protection through installation techniques. For example, using a hail guard or a roof-mounted hail protection system can help deflect or absorb hail impacts and reduce the risk of damage to the solar panels.
