Solar panels are a popular and efficient source of renewable energy that can last for decades. However, like any other technology, they are not immune to faults. Identifying and fixing faults in solar panels is essential to ensure their long-term functionality. In this article, we will explore the common types of solar panel faults, their causes, and how to prevent them. Solar Panel Faults: Common Types Hot Spots A hot spot is a concentrated area of high temperature on a solar panel, usually across a single cell. It occurs when a section of the panel fails to convert solar energy into electricity and instead absorbs it, causing heating. Hot spots can lead to panel damage, reduce efficiency, and in extreme cases, potentially start a fire. PID (Potential Induced Degradation) PID is an electrical phenomenon that causes a significant drop in the output power of a solar module panel. It occurs when a voltage difference develops between the solar cells and the grounded frame, leading to a le...
