Performance investigation of a hybrid photovoltaic-thermal (PV/T) system

In this study, electrical and thermal performances of a hybrid photovoltaic thermal system (PV/T) which built in Bal？kesir University Campus area were investigated. The off-grid electrical performance of the system with batteries has been evaluated. It is found that the thermal efficiency of this system changes between 49.9% and 52.11% by the measurements in 0.015, 0.044 and 0.069 kg/s flow rates. In August, the state of charge of batteries change between 40% and 100% while the system feeds the specified load profile. Additionally, the electrical output of the cooling and uncooling of PV/T panel in the maximum power point were compared resulting approximately 12.9% increasing power. The electrical efficiency has been calculated as 12% for cooling system
