Hyundai Photovoltaic Panel PALET - - 31 pc x 445 Wp Mono: NUJD445 SHARP photovoltaic solar panel NUJD445, monocrystalline, IP68, 445W The main benefits of half-cell modules for users are the module performance with higher 2-3% and higher total yields.In a half-cell module, standard solid cells are cut into two equal halves.In addition, the module is also divided into an upper half and a lower half, and the half-cells are arranged on it.By dividing the cells, the power generated per cell is reduced by half, and the resistance losses at the level of the cells and the module are reduced to a quarter.In addition, halving the current can significantly reduce the temperature in the cells and therefore reduce the risk of hot spot effects.The three small junction boxes, each equipped with a single bypass diode, transfer less heat to the cells below.These factors also increase the longevity of the entire system, and splitting the module in half will also have an impact on overall performance.The path of the generated current is shortened by dividing the module, further reducing resistance losses.Mounting the module vertically will also prove beneficial in shady situations.For example, if the bottom half of the module is shaded, users can still generate a performance of 50% with the top half, while the output of a full cell module falls off completely.This could be the case of shading between the rows for roof installations in open field or inclined.Therefore, with half-cell modules, higher power classes and higher efficiencies per system can be achieved.Download technical details
