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.

As some brands cut corners on product quality to remain price-competitive, solar panels start to fail in the field before their expected lifetime is up. 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.

Sometimes hotspots appear as brown spots or noticeable damage on the surface of the panels. But most of the time, hotspots are not visible to the naked eye. But if you cannot see it, it doesn’t mean that it’s not there! The best way to detect hotspots is through thermography, which highlights the overheated spots.

The hotspot effect refers to localized areas of overheating on the surface of individual solar cells within a solar panel. This phenomenon occurs when certain cells in a panel generate less electricity than other cells, leading to an imbalanced circuit of the panel.
