In order to reduce the cost of material and reach the goal of modulized manufacture,we redesign the sun-tracking device. Additionally,we explore the design of photo detector and digital sun-tracking controller. A commercial polycrystalline PV module is used for making a PV/T collector and tied in with one-axis three-position sun-tracking system. This study introduces the concept of primary-energy saving efficiency for the evaluation of a PV/T system. The experiment shows that the primary-energy saving efficiency can reach 0.50 and actually has the enhancement of PV performance. |
