Feasibility Study of an Off-Grid Biogas Solar Hybrid System for a Dairy Hub at Pabna Zone in Bangladesh

The major attempt of this paper is to solve the electricity demand of a dairy farm community in a rural area. Biogas and solar are two such renewable energy resources, which can meet a great amount of power lacks of this community. A feasibility study of a solar-biogas hybrid system is performed for a community of dairy farms of Pabna district in Bangladesh using simulation software HOMER. The predicted monthly average daily radiation in the area is 4.76896kWh/m2. Also, there is a huge opportunity to produce electricity from wastes of dairy farms. Three nearby dairy farms can supply approximately 1700kg of cow dung, from which 98159 kWh electricity may be produced every year, which can meet the power requirements of the farm owners. The farm owners can sell the excess electricity to the other nearby houses and shops around the plant. The system is economical, environmental friendly and makes an easy access to the rural people, who are still deprived from electricity.
