Solar energy have massive energy potential, however, they are generally diffused and not fully accessible, most of them are intermittent, and have distinct regional variabilities. In order to solve these problems, nowadays, significant technology progress is required such as improving the collection and conversion efficiencies, lowering the initial and maintenance costs, and increasing the reliability and applicability and so on.
The variations of solar collector efficiency was investigated in this study with the flow rate, solar radiation and collector inlet temperature. We used the solar simulator so that light intensity could be maintained constant. As results, we learned that collector efficiency varies greatly depending on the change in the flow rate through the solar collectors. If the flow rate through collector is to optimized, the solar efficiency could be improved about 30% compared with the existing system. It was also expected that solar heat gain could be increased significantly with the optimal control of the collector inlet and outlet temperature difference.
