Abstract

 At favourable conditions, the average intensity of solar power is about 0.8 KW/m2 at noon for a clear summer day in Kuwait, Assuming a photovoltaic system total efficiency to be 6%, the corresponding specific area required during this favourable atmospheric conditions will be about 20 m2/kW; which has to be increased considerably for the rest time of the day and year, unless a tracking solar system is used to limit to some extent the increase of this specific solar, area. 

In order to obtain a further decrease of such a specific solar area, conical concentrators are suggested to be used with the photovoltaic cells in addition to the tracking solar system. 
In this paper a comparison between the experimental voltage-current characteristics of one type of photovoltaic cells with and without concentrators is presented; illustrating the design and shape of these concentrators when used with photovoltaic cells as applied to a solar cooling system in arid zones.
