The overall advantage of 210mm size solar #cells is to reduce costs and improve efficiency Solar cells are the intermediate products from solar silicon wafers to photovoltaic modules, and the cost of solar cells determines the cost of photovoltaic modules, the main equipment of the photovoltaic system. Therefore, looking at the future potential of the size of photovoltaic modules, it is inevitable to first see the potential for cost reduction per watt. At this point, the excellence of the 210mm size is outstanding. #SpolarPV #550W
