Each square meter of reflector surface in a solar field is sufficient to avoid the annual production of 150–250 kg of carbon dioxide . There are four main types of solar concentrators for the production of energy from the sun''s rays, namely parabolic trough collectors [ 3, 4, 5 ], Fresnel mirrors [ 6, 7, 8 ], solar towers [ 9, 10, 11 ] and solar dishes [ 12, 13, 14 ].
One measure of the performance of a solar thermal system is the solar fraction (SF), defined as the annual useful produced heat by the solar collectors divided by the total annual need of energy. Generally, it is desirable to have a high SF for installations in single family houses
