Hot spot effects account f or a large proportion of photovoltaic module failures, so it is of engineering significance to study them and put forward sugge stions for fault prevention. modules. Finally, it puts forward some measures to prevent faul ts to improve the operational reliability of photovoltaic modules. 1. Introduction
Hot spots result in increased resistance in affected cells, leading to power dissipation as heat. This energy loss reduced the overall power output of the panel, resulting in lower efficiency and decreased electricity generation. The higher the number and severity of hot spots, the greater the impact on the panel’s overall performance.
Further investigations have linked the occurrence of PV hotspots to physical imperfections, such as micro-cracks within solar cells , . These defects are not merely a thermal hazard but can also considerably diminish the electrical output of PV modules.
The higher the number and severity of hot spots, the greater the impact on the panel’s overall performance. Continuous exposure to hot spots can cause physical damage to solar cells, leading to permanent degradation and reduced panel lifespan. Excessive heat can cause cell delamination, solder joint failure, or even cell cracking.
In this context, the challenge of hotspot mitigation within PV modules has emerged as a critical area of research and development. This paper presented a novel electronic circuit designed to address the pervasive issue of hotspots in PV modules, which are known to precipitate efficiency losses and potentially hazardous operating conditions.
Shading on a solar panel can cause certain cells to become inactive, resulting in poor power output and increased resistance. These shaded cells can create hot spots as they become reverse-biased and start dissipating energy in the form of heat.
