Common Defects of Solar Panels: Hot spots, Discoloration and Delamination
If your solar system isn't producing as much energy as it should, equipment problems could be the cause. According to the 2025 report, hardware issues Hot spots and Delamination increased losses globally by 214% from 2019, leading to losses of around $10 billion in 2024.
Common defects
Aging solar panels often suffer from discoloration, delamination and diode failures. These problems reduce efficiency and can lead to expensive repairs.
Signes Discoloration
1. UV Radiation: Prolonged exposure to UV rays can degrade the materials inside the panel.
2. Moisture: Ingress of moisture can cause mold growth and similar problems.
3. Poor Maintenance: Irregular cleaning can lead to dirt build-up.
How to Recognize Problems
– Discolouration: The first signs of damage, usually appearing as brown or yellow spots.
– Hotspots: Overheating can cause serious consequences such as burns.
How To Protect Yourself
Regular checks and monitoring of solar systems are key to timely detection of problems. If you notice a drop in energy production or discoloration, it's time to act.
