How many volts does a PV module produce?

Cell: The basic photovoltaic device that is the building block for PV modules. All modules contain cells. Some cells are round or square, while thin film PV modules may have long narrow cells. Cells are too small to do much work. They only produce about 1/2 volt, and we usually need to charge 12 volt batteries or run motors.
