Solar panels Data Sheet
The photovoltaic effect is the conversion of sunlight into electricity. This occurs when the PV cell is struck by photons (sunlight), ''freeing'' silicon electrons to travel from the PV cell, through electronic circuitry, to a load (Figure 1). Then they return to the PV cell, where the silicon recaptures the electron and the process is repeated.
Design and Sizing of Solar Photovoltaic Systems
1.1.1. Solar Cell The solar cell is the basic unit of a PV system. A typical silicon solar cell produces only about 0.5 volt, so multiple cells are connected in series to form larger units called PV modules. Thin sheets of EVA (Ethyl Vinyl Acetate) or PVB (Polyvinyl Butyral) are used to bind cells together and to provide weather protection.

Photovoltaic Cells
The I PV PV current increases in proportion to the incident irradiance. If the spectrum does not change, the I PV is directly proportional to irradiance I PV = C G G.Then, at a constant temperature, the V OC increases with irradiance logarithmically, as follows from Eq. (18.16). In the case of real cells, the I–V characteristics are influenced by the series resistance R s.
