Abstract
The performance of series connected tube in plate flat plate water collectors partially covered by the photovoltaic module has been evaluated on annual basis. The system consists of 5 partially covered photovoltaic thermal (PVT) water collectors having 2 m2 area. The annual energy has been estimated by considering all types of weather conditions for New Delhi India. The solar radiation data provided by Indian meteorological department (IMD, Pune) has been used for computing the annual energy. The overall thermal energy and exergy saved by the system are estimated as 10 MWh and 0.887 MWh respectively. The carbon credit earned by the system in a year on overall thermal energy basis is found to be USD 296.1 and on exergy basis it is USD 26.2. The energy payback time on overall thermal basis and exergy basis was found to be 1.6 years and 17.8 years respectively.
