The short answer
How Storms Damage Panels
Hail is the most common cause of cracked solar panel glass. In a humid subtropical climate like Rockwall, spring thunderstorms can bring hail large enough to dent a car roof. A direct hit on a panel can shatter the tempered glass, exposing the photovoltaic cells underneath.
High winds can also lift panels or hurl branches and other debris into them. A falling limb can crack the frame or scratch the glass, which weakens the panel. Even a small crack lets moisture inside, which can corrode the wiring and reduce power output over time.
- Cracked glass from hail impact
- Loose mounting from wind lift
- Scratches from flying debris
- Broken frames from falling branches
- Water intrusion through micro-cracks
Signs of Damage After a Storm
Look for visible cracks, chips, or shattered glass on the panel surface. Check the mounting rails and bolts to see if anything shifted or came loose. Also inspect the wiring and connections for any exposed or frayed cables.
If the panels still produce power but you notice a drop in output, that can signal hidden damage. Water inside a panel may not be visible from the ground. A professional inspection can catch issues you might miss, especially if you cannot safely get on the roof.
What to Do If Panels Are Damaged
If you see damage, turn off the solar system at the inverter or main disconnect if you can do so safely. Do not touch wet or cracked panels, as water and electricity are a dangerous mix. Keep yourself and your family away from the affected area.
Contact a qualified solar installer or an electrician to assess the damage. They can tell you whether a panel needs replacement or just repair. If water has entered the roof or walls, you may also need water damage cleanup to prevent mold and rot.
- Turn off the system at the inverter
- Stay away from wet or cracked panels
- Call a solar installer or electrician
- Document the damage with photos
- Check your insurance policy for coverage
Preventing Future Storm Damage
A properly installed system is more likely to withstand a storm. Make sure your panels are mounted with strong brackets and that all bolts are tight. Trim nearby trees that could drop branches onto the array.
Some panels are built to withstand higher hail impact, but no system is completely storm-proof. If you live in Rockwall, keep your insurance policy information handy so you can file a claim quickly if needed. Regular inspections before storm season can help spot weak points.
When to Call Water Damage Pros
If a storm breaks your panels and water gets into your roof or attic, you may need more than a solar repair. Water can soak into insulation, drywall, and wood framing, leading to mold growth and structural damage. Acting quickly reduces the harm.
Local water damage pros can extract standing water, dry out soaked materials, and map the moisture to find hidden wet spots. They can also handle debris removal if branches or shingles fell into your yard. Their work helps prevent long-term issues like rot and mildew.
- Extract standing water from the home
- Dry out wet insulation and drywall
- Map moisture to find hidden damage
- Remove storm debris from the property

Will my insurance cover storm damage to solar panels?
Policies vary, and your insurer decides what is covered. Homeowners insurance often covers storm damage, including hail, but you need to check your specific policy. Some policies have separate deductibles for wind or hail. Contact your insurance company to ask about your coverage.
Can a cracked solar panel still produce electricity?
A cracked panel may still produce some power, but its output is often reduced. The crack can let moisture in, which can cause corrosion and further damage. Even if it works, it is safer to have it inspected and replaced if needed. Do not rely on a damaged panel.
How soon should I check my panels after a storm?
Check your panels as soon as it is safe to go outside. Look for obvious damage like cracks or fallen branches. If you cannot see clearly from the ground, wait for a professional to inspect. Acting quickly helps you document damage for insurance and prevents water from seeping into your home.
