PV cells are manufactured as modules for use in installations. Electrically the important parameters for determining the correct installation and performance are: 1. Maximum Power - this is the maximum power out put of the PV module (see I-V curve below) 2. Open circuit voltage - the output voltage of the PV cell. .
Nominal rated maximum (kWp) power out of a solar array of n modules, each with maximum power of Wp at STC is given by: The available solar. .
As the temperature of PV cells increase, the output drops. This is taken into account in the overall system efficiency (η), by use of a temperature derating factor ηtand is given by: .
To understand the performance of PV modules and arrays it is useful to consider the equivalent circuit. The one shown below is commonly. .
