Factory sale mono 144 cell half cut solar panel with TUV/CE certification from 410w to 430w

    Compared with conventional components, the cost of Sunrover half cell panels mainly increases in the manufacturing process, including battery slicing, auxiliary materials and labor costs, equipment depreciation costs, etc. However, the power of the half chip module can be improved by 5W-10W or even higher than that of the same version of the module. As the component price continues to decline, the overall system cost of the half chip component is reduced.Because the internal circuit and internal friction are reduced, the packaging efficiency is improved; In addition, the working temperature of the module is reduced, reducing the probability of hot spots, and improving the efficiency and safety of the module. In terms of shadow occlusion, due to its unique design, it has better anti occlusion performance than conventional components.Compared with traditional components, half cell panels are mainly shown in three aspects:

1. Reduce heat generation and temperature loss Due to the reduction of internal current and internal loss, the working temperature of components and junction boxes decreases, and the probability of hot spots and the risk of damage to the entire component are also 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.

2. Reducing shielding loss The half piece module, with its special parallel string structure, can improve the support and land utilization rate while reducing the power loss caused by shadow shielding.

3. Improve packaging efficiency. The packaging loss of conventional components is generally greater than 1%, while that of half chip components is generally about 0.2%. Therefore, the half chip module makes use of the low current characteristics to effectively improve the packaging efficiency of the module.
