Why Cutting Solar Cells?
By cutting solar cells into halves, the current produced by each cell is halved, resulting in lower resistance losses as the current flows through the cells and wires of the solar panel. Using the formula for electric power loss P=I2RP = I^2RP=I2R, when the current is reduced to one-third of its original value, the power loss is significantly ...
