AI Customer ServiceHot 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.
The large-scale hot-spot phenomena may develop from localized temperatures anomaly within a unit cell in the module while current researches generally ignored this small-scale but important problem. In this paper, close inspection of localized hot spots within photovoltaic modules is conducted with a xenon lamp of simulating the solar irradiation.
The hot-spot phenomena suppress the output photocurrent of PV modules, reducing the economic benefits of PV power stations. More seriously, hot spots may expand from one cell to a mass of cells around the original one, causing irreversible damage to the modules , .
The research demonstrates the effectiveness of studying hotspot risk with FEA method and how to contain the hotspot risk of high wattage solar modules by design optimization. With the rapid increase of solar module wattage from about 300 W to above 650 W, it is important to study the impact of high wattage on the hot spot risk.
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.
With the rapid increase in the wattage of solar modules from about 300 W to above 650 W, it is critical to investigate the hotspot risk.
