Due to the existence of the local shadow, the current and the voltage of certain single cells in the solar cell module are changed. As a result, the product of the local current and voltage of the solar cell module increases, and a local temperature rise occurs in the solar cell module. Defects of certain cell single sheets in the solar cell module can also cause the module to generate heat locally during operation, and the phenomenon is called a 'hot spot effect'.
Under certain conditions, the shaded solar cell modules in the serial branch are used as loads to consume energy generated by other illuminated solar cell modules. The shielded solar cell module will generate heat at this time, and this effect can seriously damage the solar cell, may seriously melt the solder joint, damage the packaging material, and may even make the whole module fail, and a part of the energy generated by the solar cell with light may be consumed by the shielded cell.
