Solar energy is one of the components of the State's commitment to sustainable development. It is part of its strategy to diversify its means of production and strengthen its efforts to reduce greenhouse gas emissions. The aim of the economic feasibility study into the use of solar energy to generate electricity is to guide decision-makers towards the development of profitable wind energy projects using appropriate models. Among the wind turbine models selected technically and using the RETScreen software, we were able to identify those whose implementation is economically favourable. The Sharp NUS 5E3E3 185W single-cell models are economically unacceptable.
