4.1. Impact of Aging Factors on Lifespan Generally, the life expectancy of solar panels is 20–30 years, and this period can be decreased by the influence of some aging factors. Aging factors influence the solar panel in such a way that it starts to slowly lose its power generation capability.
Aging factors influence the solar panel in such a way that it starts to slowly lose its power generation capability. The continuation of this process for a long period triggers the reduction in power generation and, after a time, the solar panel is fully degraded before its expected lifespan.
This investigation showed that each factor affecting aging has a distinct and varied effect on PV modules. According to reports, dust can decrease solar panels’ effectiveness as it accumulates over time; nonetheless, dust’s effect on the lifespan is less severe than that of other aging factors.
The solar PV’s output power decreases as a result of these airborne particles building up on its surface and causing shedding on the PV panel. However, the shape, size, and accumulation structure of dust may affect the shedding and its effect on both the lifetime and the efficiency of the PV module.
The influence of different degradation types on the performance of PV technologies. Experimental tests about formation of cracks and formation of bubbles on solar cells. An analysis of the electrical parameters evolution that represent cell performance. Photovoltaic technology has played an increasingly important role in the global energy scenery.
The degeneration of solar cells is brought on by their discoloration, which can lead to irreversible cell degradation and accelerate aging [67, 68, 69]. This degradation is often seen after a prolonged period of exposure and worsens over time. Figure 3 illustrates the aging process due to discoloration.
