Abstract

The sun is the only star that obviously affects our lives, not only the day but also at night, but sunny and overcast days. The sun produces and radiates huge amounts of energy and provides almost all the energy we use on earth. Even the wind and the clouds are the result of the influence of solar energy on earth. The man realized the benefits of using solar radiation from the prehistoric years already. The immediate consequence was the development of technology reaching today with facilities PV Farm. This Diplomat Thesis develops curved mirrors whose use are leading technology solution of PV systems because they have a higher thermal efficiency compared to flat panels and produce more energy per unit of surface. The solar collectors have a centralized reflector which directs sunlight from a large area in a smaller receiver and absorbent surface. The panels they could be fixed or be immobile. Moreover we try to analyze the main types of concentrators collectors are parabolic mirrors that concentrate solar radiation on a linear receiver. Little reference is made and parabolic dishes which resemble satellite dishes, only consisting of absorber, which can reach 1000oC and thus achieving greater efficiency. In this Diplomatic Thesis there is a great reference in designing various systems and more specifically to parabolic collectors CPC, which is made from two half parabolic reflector and a metal reflector enabling them to channel and direct and diffuse radiation.
