Solar photovoltaic systems: components

Photovoltaic modules

Photovoltaic modulesi are the main element of the system: consisting of solar cells that convert light into electricity. A solar cell can be made from a monocrystalline, poly- or multicrystalline silicon wafer, or from a "thin film" wafer (on support structures such as glass or metal).
Their efficiency is expressed in Watt-peak (Wp),which is the basic measure of performance under standard testing conditions.
