The Research on the Angle of Quasi-fixed Solar Collector.

Abstract: In this paper, in order to increase the efficiency of solar energy collection in winter, a method to set the semi-fixed collector was proposed. The best angle of the quasi-fixed solar collector have be calculated and given in Daqing region. According to comparison and analysis, we find that the efficiency improved 8.3%; it will collect solar energy 410.46MJ per square more than fixed collectors every year. [Copyright &y& Elsevier]
