Can Solar Panels Be Damaged by Severe Storms?

Most solar panels are designed for durability and can withstand hail or wind speeds as high as 140 miles per hour. A severe storm that damages a roof or is accompanied by flying debris may also damage panels. Find out more about the most common forms of panel damage and how to plan ahead and protect these components.

The Effects of Adverse Weather

Roof-mounted panels may succumb to general roof damage. This includes several incidents:

• Broken panels
• Damage due to flying debris
• Dislodged panels

Panels that are less expensive and well-made may be more likely to break. Most high-quality panels are certified to withstand hail with a one-inch diameter falling at 50 miles per hour and high wind speeds. Roof-mounted panels are also typically secured to roof beams with lag bolts.

How To Prevent Panel Damage

Homeowners can take several measures to prevent panels from becoming damaged. These considerations start during the panel selection process and continue throughout installation:

• Invest in high-quality panels
• Check panel design damage ratings
• Anchor panels to roof beams with lag bolts
• Ask installers about common causes of damage

All of these measures can reduce the likelihood that solar panels will sustain damage even during the most severe storms. Lag-bolted panels are positioned within a few inches of a roof surface and should be capable of withstanding intense uplift force. Installation professionals can also provide insight into some of the most common causes of damage in a particular region and install panels in ways that may prevent damage from occurring.

Most industry-leading solar panel designs combine durable aluminum with glass casings to protect solar cells and prevent panel damage. These panels should be capable of standing up to adverse weather conditions. If roof damage results in leaks or damages the interior of a residence, homeowners should rely on a mitigation and restoration service in Pleasanton, CA.
