Features
(1) The cell is divided into two, the main grid current is halved, and the current loss of the whole module is reduced to 1/4 of the original, and the output power is about 5-10W higher than the same version of the whole cell module;
(2) The hot spot temperature of the half-cell battery module is about 25℃ lower than the temperature of the same version of the whole battery module, which can effectively reduce the hot spot effect of the module;
(3) The half-cell battery module meets the design requirements of the 1500V system voltage, which can reduce the system-side cost by about 10%;
(4) In case of obstruction and dust and snow accumulation on the lower edge, effectively reduce the loss of power generation caused by obstruction;
(5) Reduce the first year and average light-induced attenuation;
