Structure of compound parabolic solar photovoltaic concentrator . Another structure is a system consisting of reflectors with different radius of curvatures in order to study the influence of the radius of curvatures on the collecting energy of the solar cell and thus its output power as shown in Fig. 6 where the available curves are focal length (a = 0.1m) and (a=0.3m).

The aim of this work is to use the PV solar concentrator in order to lessen the amount of expensive solar cell by depressed cost optical materials. A compound parabolic concentrator (CPC) with two opposite paraboloid mirrors has been fabricated. Each mirror connected to two steel bars from both sides and these bars fixed on aluminum base. The two m...

... to vertical motion in order to change the height of concentrator. The aluminum base connected with a circular wheel to change the tilt angle of CPV. The assembly of solar cell and cooling system has been installed in the focal plane of the concentrator. The assembly structure of compound parabolic solar photovoltaic concentrator is shown in Fig. 5. .

In this paper, a concentrating photovoltaic system (CPV) by using a compound parabolic concentrator and a monocrystalline solar module has been designed and studied theoretically under a concentration ratio of 3.16x. The performance the system is studied over the course of the day from 8:00 AM to 16:00 PM for 12 months under Iraq-Baghdad conditions. Current in a short circuit (I sc ), voltage in an open circuit (V oc ) as well as maximum power (P m ) are calculated with and without a concentrator under constant solar module temperature (25°C). The results indicated that the optimum value of output power can be obtained on June 21, which is about 246.9W for CPV. In the second part, the effect of solar cell temperature within a range of 25 °C−115 °C on its performance has been studied for the optimum day of the year, June 21st. The output power of the device may be viewed in CPV is 246.9 W in comparison to the flat PV module, which gives 83.44W under solar cell temperature of 25°C and decreases to 125.3W and 40W under cell temperature of 115°C for the CPV and flat module, respectively.
