Quick Answer
Tempered glass solar panels can withstand extreme weather conditions, including storms, with a lifespan of up to 25 years or more, provided they are properly installed and maintained. However, exposure to hail can potentially cause damage to the glass and impact the panel's performance. The extent of damage depends on the size and velocity of the hailstones.
Understanding Hail Damage to Solar Panels
Tempered glass solar panels are designed to be durable and resistant to extreme weather conditions, including storms and hail. However, hail can cause damage to the glass, which may lead to cracks, breaks, or other forms of damage. The size and velocity of hailstones are critical factors in determining the extent of damage to solar panels.
Hail Testing and Standards
The International Electrotechnical Commission (IEC) has established standards for testing the hail resistance of solar panels, including IEC 61215 and IEC 61730. These standards outline the procedures for testing the panel’s ability to withstand hailstones of various sizes and velocities. Panels that meet these standards have undergone rigorous testing to ensure their durability and resistance to hail damage.
Assessing and Repairing Hail Damage
If a solar panel is damaged by hail, it’s essential to assess the extent of the damage and determine the best course of action for repair or replacement. This may involve inspecting the panel for cracks, breaks, or other forms of damage, and evaluating the impact on the panel’s performance. In some cases, it may be possible to repair the panel, while in others, replacement may be the best option.
