In the present analysis, a photovoltaic (PV) integrated greenhouse system under forced mode developed for biogas heating. Different factors have been assessed for weather condition of IIT, New Delhi, India. Ambient air temperature and radiation data have been measured experimentally. Further, thermal model has been derived for the PV greenhouse and various factor like greenhouse air temperature, solar cell temperature, and outlet air temperature through duct have been evaluated with the help of MATLAB 2013a software. Thermal energy, electrical energy, overall thermal energy, overall thermal efficiency, cell efficiency and thermal efficiency have been calculated. Thermal energy, overall thermal energy electrical energy and for a clear day found to be 4.55 kWh, 0.60 and 6.14 kWh respectively. Further, overall average thermal efficiency throughout the day found to be 69%. © 2016 IEEE.
