Solar Panel Damage from Hail or Storms (Troubleshooting & Fixes)

    Seeing hail damage on your solar panels or a drop in power? A 25+ year vet explains how to spot the problem, what to do, and when to call a pro.

    DIY Fix: $5–$20

    Quick Answer

    Okay, so here's the quick version after a nasty storm. First, visually inspect your panels from the ground – look for cracked or shattered glass and any obvious dislodged panels. Next, check your solar monitoring app; if your energy production has significantly dropped or is zero, you likely have a problem. Do not attempt to climb on the roof yourself, as damaged systems can pose electrical and fall hazards. Any significant damage like cracks, loose panels, or wiring issues is a job for a qualified professional. A standard inspection visit will typically cost $150-$500, which is well worth it for a proper diagnosis and safety check. If a panel needs replacing, you’re looking at $400-$1,200+ per panel, including parts and labor, depending on the panel type and accessibility. Inverter or microinverter replacement can range from $500 to $2,500+.

    Common Symptoms

    Cracked or shattered glass on the solar panels (spiderwebbing)
    Significant, unexplained drop in daily energy production visible on your monitoring app
    The system is completely offline (producing zero power)
    Visible dents or pockmarks on the panel's aluminum frame
    Inverter is displaying error codes, alarms, or flashing red lights
    Visible loose, frayed, or disconnected wiring on or around the array

    Possible Causes

    Direct impact from large hail (typically over 1-inch in diameter) shattering the tempered glass.
    High winds causing tree branches or other debris to fall onto or be thrown into the panels.
    Extreme wind loading creating uplift that bends the racking or pulls panels loose from their mounts.
    Nearby lightning strikes inducing a high-voltage surge that can fry the inverter or microinverters without visible external damage.
    Water intrusion into a previously cracked or damaged panel, causing short circuits and component failure over time.

    Step-by-Step Diagnosis

    1

    Step 1

    Visual Inspection FROM THE GROUND. Use binoculars to carefully examine each panel for cracks, chips, or shatters. Do not climb on the roof.

    2

    Step 2

    Monitor Energy Production. Open your solar monitoring app and compare the current production to a similar sunny day before the storm. Look for a significant drop or panels reporting zero output.

    3

    Step 3

    Check the Inverter. Look at the main inverter box for any warning lights or error codes. Write down the specific code to reference in the manual or provide to a technician.

    4

    Step 4

    Inspect Accessible Wiring. From a safe distance, look for any obviously disconnected, dangling, or damaged wires near your inverter and ground-level conduits. Do not touch anything.

    5

    Step 5

    Document All Damage. Take clear photos and videos of damaged panels, racking, and any inverter error screens. This is crucial for insurance claims.

    When to Call a Professional Solar

    • The moment you see any crack, chip, or shattered glass on a panel.
    • If your system's power production has dropped significantly and isn't recovering.
    • If your inverter is showing a fault or error code that doesn't clear after a simple reset.
    • If you see any loose, dangling, or damaged wiring.
    • When you need a professional quote to submit to your insurance company for a claim.

    Prevention Tips

    • Invest in high-quality, Tier 1 solar panels that have strong hail impact resistance ratings from the start.
    • Ensure your system is installed by a reputable, NABCEP-certified professional who will properly secure and torque the racking system to withstand high winds.
    • Regularly trim back any large tree branches that overhang or are near your solar array to prevent debris from falling on them during a storm.
    • Proactively review your homeowner's insurance policy to confirm that your solar array is covered, preferably for full replacement cost.
