Solar panel physical cracked hail event — hail event

Use only checks that match the exact appliance or system and its official guide.

1. Check 1

   From a safe location, keep people, pets, and visitors away from the array and any area below loose or broken modules; do not touch fallen glass, cables, racking, or wet electrical equipment.

   Expected result: Note smoke, fire, arcing, a burning odor, heat, an exposed conductor, a module hanging or shifting, water near an inverter, a roof or structure that looks unstable, or none of these signs.

   Next step: For smoke, fire, or active arcing, move away and contact emergency services from a safe location. For other hazards, maintain the exclusion area and request urgent qualified solar service.

   Stop if: Do not pick up glass, brace a module, dry equipment, or enter a wet or unstable area.

   Why this matters

   Why: Smoke, fire, arcing, exposed conductors, loose overhead equipment, or an unstable structure is an immediate hazard rather than a DIY diagnosis. No visible emergency sign only means that safe documentation may continue; it does not clear the array.

2. Check 2

   Photograph the array and roof from the ground or another stable location that does not require a ladder or contact with PV equipment; record the hail date and which module row appears affected.

   Expected result: Record visible shattered or spiderwebbed glass, a dark or cloudy area, frame deformation, a displaced module, loose hardware, detached cable, roof-covering damage, broken skylight, gutter debris, or no visible damage.

   Next step: Save dated wide and close ground photographs, mark the module location on a simple array sketch, and give them to the solar contractor and insurer if a claim is being considered.

   Stop if: Do not climb onto the roof, step on a module, scrape the surface, wash it, or use a drone or ladder in unsafe weather just to obtain a closer image.

   Why this matters

   Why: Visible glass or structural damage supports keeping the affected system out of service pending professional inspection. No visible damage cannot rule out cell microcracks or cable and racking damage because hail impact can be random and some damage is hidden.

3. Check 3

   Without changing settings or opening equipment, save the inverter display or monitoring-app status at the time of the storm and again after it, if the information is visible from a normal user interface.

   Expected result: Record normal production, a sudden output change, an inverter or rapid-shutdown warning, unavailable data, repeated trips, or no status information; include the time, daylight, and weather context.

   Next step: Provide screenshots and the timeline to the qualified solar technician; let that technician determine safe shutdown, electrical testing, and return-to-service steps.

   Stop if: Do not repeatedly reset the system, change protection settings, open the inverter, pull a PV connector, or operate an unfamiliar disconnect as an experiment.

   Why this matters

   Why: A warning or production loss increases the need for prompt qualified diagnosis. Normal production does not prove that a visibly cracked or internally damaged module is safe, because damaged cells may continue to produce before degradation or a fault becomes obvious.

4. Check 4

   From safe ground-level viewpoints and from inside the building, note roof leaks, ceiling staining, broken skylights, damaged roof coverings, gutter debris, and whether water is approaching electrical equipment; do not inspect by walking on the roof.

   Expected result: The roof appears dry and intact, a leak or broken opening is visible, water is entering near the array, the mounting appears displaced, or the condition cannot be judged from below.

   Next step: Photograph the interior or ground-level signs and ask the solar contractor to coordinate with a qualified roofer when the roof covering, flashing, underlayment, or array attachment may be involved.

   Stop if: Do not remove roof material, lift a module, move racking, open a ceiling, or touch a wet electrical enclosure.

   Why this matters

   Why: A leak or displaced mounting may require coordinated roof and solar assessment, not just module replacement. A dry interior does not rule out damage beneath the array, and an inaccessible condition should remain untested rather than prompting roof access.

5. Check 5

   Request an assessment from a qualified solar PV contractor and provide the array location, photos, module label if readable from the ground, storm date, monitoring history, alarms, and any roof or water observations.

   Expected result: The contractor confirms visible glass or backsheet damage, suspected cell microcracks, cable or connector damage, displaced racking, roof damage, or no confirmed damage after visual and electrical testing.

   Next step: Keep the affected area isolated until the contractor says the system is safe and repaired; ask for the inspection findings, testing performed, replacement scope, and documented return-to-service decision.

   Stop if: Do not perform insulation, current, voltage, infrared, or electroluminescence testing yourself and do not reconnect or repower a visibly damaged system.

   Why this matters

   Why: A damaged module may need replacement, while hidden cell, string, wiring, racking, or roof findings can change the repair scope. The decision belongs to the trained technician using appropriate inspection and electrical tests, not to a normal production reading or a guessed replacement part.
