Chapter 9: Small Photovoltaics.

 

 

 
     
  Summary  
 
        This chapter addresses common PV practical applications which are made of small number of PV cells or modules operating under natural or artificial light. An effective irradiance value is calculated to take into account different spectrum of artificial light. Correspondence between radiometric and Photometric quantities is used. The random generation of I(V) characteristics of small PV modules is performed and Monte Carlo randomly generated numbers are used to generate Pspice time series of radiation which can be used to see the PV system operation in detail. This method is used to show how a solar pocket calculator works as well as a flash light and a street light system as casestudies.
