Abstract: T he coo ling of concentrating pho tovo ltaic so lar cell
system s w as investigated experim entally w ith w ater as the coo lant.
O rdinary so lar cells w ere used w ith so lar fluxes of 0. 8520 kW gm 2
w ithout coo ling and w ith natural convection of w ater.
T he resulting
pow er w as compared to the m axim um electrical output of o rdinary
so lar cells w ith no concentration at a ligh t intensity of 1 kW gm 2 .
T he op tim um concentration intensity of the o rdinary so lar cells w ith
no coo ling w as found to be 3. 3 kW gm 2
at w hich the m axim um
Key words: so lar pow er system; so lar cell; concentration
