Evaluation the impact tilt angle on the Sun collectors

Abstract

In order to efficiently solve the problems created by the deepening energy crisis affecting Europe and the world, governments cannot neglect the opportunities of using the energy produced by sun collectors. In many of the EU countries there are sun collectors producing heat energy, e.g. in Austria more than 3,500,000m2 and in Germany more than 12,000,000m2 of sun collectors are operated [5] . The energy produced by these sun collectors is utilized at the place of production. In the near future governments will have to focus more on spreading and using sun collectors. Among the complex problems of operating sun collectors, this article deals with determining the optimal tilt angle of sun collectors. The tilt angles which we determined theoretically are confirmed by laboratory measurements. The result of our work will help users and engineers to determine the optimal operation of sun collectors.
