About What to do if there are spots on photovoltaic panels
If you see dark spots on your panels, this could be a sign that your panels are undergoing delamination, and you should contact your installer for an inspection.
If you see dark spots on your panels, this could be a sign that your panels are undergoing delamination, and you should contact your installer for an inspection.
Hot spots, one of the most common issues with solar systems, occur when areas on a solar panel become overloaded and reach high temperatures relative to the rest of the panel. When current flows through solar cells, any resistance within the cells converts this current into heat losses.
Here are 11 of the most common solar panel defects to watch out for in a solar installation, and how WINAICO works to prevent them from happening to your sites. Hot Spots Speed up the Degradation of Solar Cells.

6 FAQs about [What to do if there are spots on photovoltaic panels]
How to detect hot spots in solar panels?
You can detect an emerging hot spot with an infrared camera only. Eventually, hot spots in solar panels become visible to the eye: the problematic cell becomes brownish. Hot spots lead to a faster solar panel degradation and can even start a fire on your roof. To avoid that, clean your panels from dirt every now and then.
What causes hot spots on solar panels?
Hot spots, one of the most common issues with solar systems, occur when areas on a solar panel become overloaded and reach high temperatures relative to the rest of the panel. When current flows through solar cells, any resistance within the cells converts this current into heat losses.
What should I do if my solar panels fail?
Double-check the wiring and grounding, as faults with them can lead to power loss, voltage drops, or electrical fires. Ensure your panels have enough natural airflow around them to provide proper ventilation. That way, you can prevent installation-related common problems with solar panels.
How do I know if my solar panel is broken?
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. Even if you buy the perfect solar panel and place it on a suitable roof, you are not immune to solar panels breaking.
How can you prevent problems with solar panels?
Ensure your panels have enough natural airflow around them to provide proper ventilation. That way, you can prevent installation-related common problems with solar panels. Ensure workers use suitable hardware, as slightly mismatched inverters and connectors are a common installation issue.
How do I know if my solar panels are delaminated?
If you see dark spots on your panels, this could be a sign that your panels are undergoing delamination, and you should contact your installer for an inspection. Micro cracks are tiny tears in solar cells stemming from haphazard shipping and installation or defects in manufacturing.
