In this paper; the energy balance equations for the different components of hybrid photovoltaic thermal (HPVT) biogas plant have been written for quasi - steady state conditions to develop a thermal model. An analytical expression for slurry temperature has been obtained as a function of design and climatic parameters namely mass of the slurry; mass flow rate of fluid in collector; number of collectors; solar intensity; ambient temperature etc. Numerical computations have been carried out for climatic conditions of Srinagar; India. Based on mathematical computations it has been observed that the optimum slurry temperature (~37oC) is achieved for a given set of design parameters of biogas plant and hybrid collectors (MS =2000; ?f =0.05kg/s; L = 25m). It has been observed that number of hybrid PVT collector has significant effect on slurry temperature.
