Path-Q Solar
How can hail damage affect solar panel performance?
Answer
Hail can crack or puncture module glass, damage cells, frames, connectors, or wiring, and cause either an immediate or gradual production loss. Some damage is difficult to see, so a system may continue operating while producing less or developing later safety and reliability problems.
Key points
- Inspect from a safe location for cracks, impact marks, broken glass, frame damage, and water intrusion.
- Compare production and alerts before and after the storm.
- A professional inspection may use electrical testing or specialized imaging when damage is not visible.
What it depends on
- Hail size, speed, direction, and storm intensity
- Panel construction, age, mounting, and condition
- Extent of visible and hidden damage
- Insurance, warranty, and service arrangements
Risks and trade-offs
- Cracked or electrically damaged modules can present shock, fire, or weather-ingress risks.
- Cleaning or handling damaged panels can worsen the damage.
- Filing a claim or replacing panels before documenting the condition can complicate evidence and coverage decisions.
Information you may need
- Storm date and hail observations
- Photos from a safe location and production data
- Panel, installer, warranty, and insurance information
