Signs of Damaged Solar PanelsDecreased Energy Production One of the most obvious signs of damaged solar panels is a decrease in energy production. Physical Damage Solar panels are exposed to the elements day in and day out, and this exposure can sometimes lead to physical damage. Moisture or Water Damage . Discoloration or Stains . Loose or Broken Connectors . Cracked or Chipped Glass .
Inspect your solar panels for any visible physical damage. This may include cracked or shattered glass, loose connections, corrosion, or signs of wear and tear.
There are several tools and techniques used to determine solar panel degradation, these include visual inspection, infrared thermography, electroluminescence (EL), and performance calibration.
To determine whether your system has solar panel cracks, look for hairline fissures under the angled light, and check for slight discoloration and a white, web-like snail trail pattern.
