In developing countries like Jordan, traditional energy resources are not available, so finding other sources to pump the water for irrigation and consumption is necessary. Renewable energy sources, particularly photovoltaic (PV), can play a vital role in providing potable water and irrigating crops in Jordan. Where there is a large amount of groundwater in most areas, while the water wells are deep and far from the national electricity grid. This article compares the Present Value Cost (PVC) for the monetary estimation of energy supply for water pumping systems (WPSs) in remote areas in Ghor Al-Safi/Jordan by two different sun-energy systems, Photovoltaic thermal (PV-T), and PV systems. Several factors are considered, including energy costs and expenses of the investments. The comparison is performed for a variety of variable values, including PV system peak power, and water pumping requirements. A case study is conducted at Ghor Al-Safi/Jordan. Evaluating two energy supply WPSs, which are designed to supply irrigation water for the entire year 2020. The obtained results showed that the average monthly electricity output efficiency for “PV and PV-T” was 12.7% and 10.86%, respectively. However, the total efficiency of the “PV-T” ranged from 41.3% to 55% which is higher than the PV system. The result concluded that the application of PV-T system in Jordan is promising for solving energy demand.
