Features:
Monocrystal 445w450w455w half-cell cell is obtained by cutting the standard cell in half. Therefore, its internal current is reduced by half. As the current decreases, the power loss inside the battery decreases. The power loss is usually proportional to the square of the current, so the power loss of the entire assembly is reduced by about 1/4.
Reducing the power loss of a half-cell cell can make it have a larger fill factor, higher conversion efficiency, and greater power generation, especially in a high-radiation environment. The component has a larger fill factor, which means that its internal series resistance is small, and its internal current loss is also small
In addition, compared with standard modules, the new design of double-sided double-glass photovoltaic panels improves the electrical performance of the cells under shading or morning and evening conditions. For example, if the standard module is installed in the longitudinal direction and the bottom is shaded, the bypass diode will be turned on, short-circuiting the entire string of cells, and the output power of the entire module will be approximately zero. The half-cell module benefits from the series-parallel cell string layout, which can ensure that its output power can still be maintained at about 50% under the same conditions.
