THE OVERSIZING METHOD OF ESTIMATION IN PV SYSTEMS

The proper sizing of any photovoltaic system needs information about l oad requirements, solar radiation and temperature at the site and manu facturer's data specifications of the PV modules. This paper presents theoretical calculations of the mismatch and oversizing in PV systems. Experimental results on two solar refrigerator systems will be presen ted and discussed. It was found that the selection of a good sized sys tem is normally affected by local conditions at the site like temperat ure, solar radiation, etc.
