This study is on the analysis of feasibility for using photovoltaic (PV) panels in two Water Pumping Stations (WPS), in Fortaleza and Cascavel, in the state of Ceará. The plant PV makes use of the compensation mecanism, where the electricity generated by the PV modules is injected into the network of the local utility and the amount will be discounted in the electricity bill. The performance and analysis of the pumping PV project in WPS was carried out with the help of the RETScreen software. In this software, studies were carried out on the energy production capacity, life cycle costs and the project’s financial feasibility. For the estimation of the project’s cost of implementation three aspects are considered: the price of the PV modules, infrastructure/interconnection with the network and o the implementation costs. The study results have an estimated total cost of R$11,240,442.51 considering the installed capacity of the system is 1,793 kWp. The capital return will occur in 9.7 years, with positive cash flow from the fifth year. The results of the financial feasibility study are summarized by the RETScreen, facilitating the comparison between the indicators and the feasibility assessment. The following indicators are available: internal rate of return (IRR), net present value (NPV), time of capital return and cost benefit ratio.
