Solar panels, while durable and long-lasting, can degrade over time due to various factors. Here are some common signs that your solar panels are degrading:
Signs of Solar Panel Degradation
- Decreased Energy Output: One of the most obvious signs is a reduction in energy production. If your solar panels are producing less electricity than they used to, it could indicate degradation.
- Physical Damage:
- Cracks and Chips: Inspect your solar panels for cracks or broken glass, which can significantly reduce efficiency.
- Discoloration: Panels turning yellow or brown may indicate degradation due to exposure to sun and oxygen.
- Hot Spots: These occur when parts of the panel become too hot, potentially damaging cells. Hot spots can be caused by shading or poor installation.
- Delamination and Corrosion: Delamination (layers separating) and corrosion (due to exposure to salt or chemicals) can affect panel performance.
- Loose Connections: Issues with wiring, such as loose connections, can reduce energy output.
- Inverter Problems: Since inverters convert DC to AC power, their malfunction can significantly impact your system’s efficiency.
- Age: If your panels are more than 25 years old, they may be nearing the end of their lifespan.
- Debris and Mould: Build-up of debris can block sunlight, while mould can form from moisture accumulation on dirty panels.
- Burn Marks: These can be caused by overheating or electrical issues within the panels.
- Subpar Materials: Use of counterfeit or low-quality components can lead to faster degradation.
Regular Maintenance
Regularly inspecting your solar panels and maintaining them (e.g., by cleaning) can help extend their lifespan and prevent degradation. Monitoring their performance and addressing issues early can prevent further damage.
