    Since the voltage of the solar crystalline silicon cell is independent of the area, but the power is proportional to the area, the voltage of the half cell is unchanged compared with the whole cell, the power is halved, and the current is halved. Taking into account the support and land utilization, reduce the power generation loss caused by shielding. When the conventional photovoltaic modules are installed on the photovoltaic power station for module array layout, there are usually two ways: longitudinal layout and horizontal layout. The advantages of longitudinally arranged components are convenient installation, high bracket utilization, and small floor area. The disadvantages are that when shadows, dust, water stains, and snow cover in the morning and evening, the power loss of longitudinally arranged components is more than that of transverse components. With its special parallel string structure, the half piece module can improve the utilization rate of supports and land while reducing the power generation loss caused by shadow shielding.When the working temperature drops, the probability of hot spot decreases. As the internal current and internal loss are reduced, the working temperature of the module and junction box decreases, and the probability of hot spot and the risk of damage to the entire module are greatly reduced. Under the outdoor working condition of the module, the temperature of the half module is about 1.6 ℃ lower than that of the conventional whole module.

Resistance loss reduced by 75%, power increased by 5~10W
