It is important to identify and monitor hot spots through techniques like infrared imaging and continuous monitoring systems and implement mitigation strategies such as bypass diodes and module-level power electronics to address them. . Hot spots on solar panels are a serious issue that can significantly impact the performance and lifespan of your solar energy system. These localized areas of extreme heat occur when one or more cells in a panel become overheated, often due to shading, soiling, or internal defects. This occurrence is usually triggered by the uneven distribution of sunlight across the solar panel, a scenario that arises when a specific section of. . The best way to detect hotspots is through thermography, which highlights the overheated spots. Inside the imbalanced circuit. . A single leaf can cause significant shading on a solar panel, reducing the output of the affected panel or string, which may lower overall system efficiency by up to 10-25%, depending on the system's architecture (e. parallel, use of optimizers or micro-inverters).
