Abstract

Solar collectors are one of the most promising renewable technologies for energizing future systems. Solar collectors are used for a variety of heating systems such as domestic hot water systems and industrial application. Increasing the collector efficiency is an important factor in terms of unit cost. In this study is to increase efficiencies of flat plate solar collectors. For this purpose, various apparatus was place into collector tubes which increase the heat transfer between plate and fluid, thus it developed a new collector. In addition, a new collector hot water tank was designed. The changes in warehouse and collector were compared with the classical systems and the change in the usage water was calculated.
