Theoretical Modeling of PV Integrated Greenhouse for Fish Farming

Abstract

Variation of temperature due to climatic changes affects the yield and growth of the fish in cold climatic condition. This will impact the supply of protein rich food due to reduction in aquaculture production; one of the prime sectors for providing large scale employment. In this paper, the theoretical framework using Greenhouse and photovoltaic model is presented to maintain desired temperature in the fish water pond (18˚C to 35˚C). The controlled environment is maintained inside the greenhouse for the survival of fish in harsh weather. Greenhouse room air is heated using solar radiation to minimize evaporation and conduction losses from the surface of water pond as temperature inside greenhouse is high in comparison to atmospheric temperature. Photovoltaic modules produce electrical power which is used in various applications. Various packing factors have been taken to optimize the controlled condition inside system. It has been observed that desired temperature and maximum electrical power is achieved with 0.8 packing factor. It is clear that the proposed structure not only improves fish growth rate, promotes clean environment as renewable energy is used but also provides livelihood to fish farmers.
