Underground pump hydro system is a promising innovation technology with power generation potential for remote located farms with adequate availability of underground water resource. In this paper, the techno-economic analysis of a grid-connected solar photovoltaic with groundwater pumped hydro storage for commercial farming activities in arid areas is discussed. The main objective is to reduce the grid electricity cost for farming activities under variable time-of-use electricity tariff. The results of this study indicate that the proposed system is effective in minimizing the grid consumption costs by 95% and 32.4% in winter and summer seasons, respectively. This led to a break-even point of 7 years as compared to the grid.
