Study of Hybrid Photovoltaic Solar Thermal Systems During Summer Months in Bangladesh
Abstract
A hybrid photovoltaic (PVT) solar system combines simultaneous conversion of the absorbed solar radiation into electricity and heat. In this study the design of an experimental PVT/dual system, both air and water circulation with modifications in the air channel is presented. A thin metallic sheet (TMS) inside the air channel and painted black ribbed surfaces at the bottom of the air channel are placed. For observing the variations of heat transmittance with change of the shape of the ribs four experimental setups with a Trapezoidal, a Saw tooth forward, a Saw tooth backward ribbed surfaces and a flat plate have been used, Natural convection is applied instead of forced convection to increase the system net electrical output & thereby the overall system efficiency. All setups are of the same capacity, projected area and water heat extraction method and average depth. Performance study is carried out during the months of March to June, 2012 at IUT campus, Gazipur, Bangladesh. Significant performance has been obtained with the above stated modifications. Natural convection is allowed to take place instead of fluid convection. Results obtained in this study have been compared with available information in the literature.
