Simulation of agriculture greenhouse integrated with on-roof Photo-Voltaic panels: case study for a winter day

Abstract

This paper investigates analytical study for an agricultural greenhouse (GH) integrated with Photo Voltaic/Thermal (PV/T) units in its roof and south wall in addition to HumidificationDehumidification system (HDH). This system uses the extra solar radiation to generate electricity which is used in HDH system to condensate water recovered from plant transpiration and use it in irrigation. This system provides plants with a proper climate conditions and its requirements of solar radiation and water. MATLAB is used to develop a mathematical model based on energy equations to simulate the GH performance. The results predict that the system can be self-sufficient of energy and can provide proper conditions for the plant growth for the climate conditions of winter in Zagazig.
