Recent investigations in solar flat plate collectors

Abstract

This work provides the report on the design developments and investigations carried out in the past few years for upgrading solar collectors, which are used for effectively converting heat in the form of solar radiation into useful (Thermal) energy. It focuses on modifications in construction materials, geometry and other miscellaneous things that have been done for improvements in the collector. The details given in the paper presents recent trends, which could encourage further research in this area and will act as a guide in constructing the collector with good performance.
