In order to provide synergy from individual cells and generate a higher output, a collection of solar cells is combined to form a system provide output.
Series collection of multiple solar cells generates the requisite power needed to light up appliances. One solar module can be rated from 3 watts to 300 watts. The solar modules or PV modules are essentially the basic building block of a solar electric power generation system.
A single solar cell generates around 0.1 to 0.3 W. Hence such small cells are connected together to provide a feasible solar unit which is called solar module or PV module.
