Why cut solar cells in half?

Solar cells are cut in half to reduce the cell-to-module losses during assembly. Power loss is generally proportional to the square of the current times resistance.

Splitting the cell into two halves the current (not the voltage) of the cell, so when you apply this change to the equation the losses are reduced by 75%. The overall panel efficiency increased by 1,5-3% and this results in a reduction in panel heat production.

Cutting solar cells results in half the current, and… double the voltage. Solar modules with double the voltage would be a disadvantage, as the higher string voltage would result in half the amount of modules that can be connected per string to the inverter.
Therefore most manufacturers adopt the following string layout to produce voltages similar to standard solar modules.

The string layout also helps to reduce internal resistance and ensure optimal power production when the solar module is partially shaded.
