The main advantages of Half Cut modules for users are the increase in efficiency and total yield by about 2-3%. The presented module consists of two parts, upper and lower, on which divided cells are placed. Thanks to this treatment the power of electricity produced by the cell is reduced by half and the resistance losses at the cell and module level are reduced by 75%. Reducing the current by 50% by lowering the temperature in the cells significantly reduces the risk of hot spots.
