The sector's problems began after a round of capacity expansion in 2021, after President Xi Jinping unveiled the country's 2060 net-zero emission goals, and a target of at least 1,200 gigawatts (GW) of solar and wind capacity by 2030. Companies, including those from outside the energy sector, rushed to produce solar panels.
Severe hailstorms can seriously damage PV solar modules. Hail usually damages the front glass surface of the module and sometimes breaks the solar cell. The resulting cracks on the surface of the front glass reduce the solar radiation entering the solar cell. On the other hand, cracks in the solar cell lead to a reduction in current.
Solar modules are also vulnerable to falling objects if they are carried by the wind. Hail can damage solar modules by hitting them directly, or it can leave debris on the modules through which water can enter the PV system. Lightning is the most common cause of damage to PV systems.
