Techno-Economic Comparison of an Off-Grid PV System and Biogas System for Dairy Farming

Abstract

This paper compares off-grid solar photovoltaic (SPV) system and biogas system for a dairy farm containing 100 cows in India and gives technical and economical assessment for the same. These technologies can sufficiently provide energy for dairy farms which cannot be connected to grid due to financial reason or geographical concern. The comparative analysis for the two different renewable energy systems is based on efficiency, reliability, space requirements, gas emissions and economic viability for both the systems. Based on the findings and estimations of economic cost, efficiencies and other factors of the two systems, recommendation is to use the biogas system as it is more reliable and cost effective method for electrifying a standalone 100-cow dairy farm, based in India.

Keywords: Dairy farming, solar photovoltaic system, biogas system, anaerobic digestion, off-grid
