The climate change is increasingly apparent and the need to be independent for the sourcing of energy sources has led to the establishment of the European Community financing schemes to support research and development of systems in place to decrease pollution and independence from fossil fuels. One way to catch up with greater conviction this scope is the production of energy at a large scale, using renewable sources. Now, the incentives are even a fundamental element for the development and competitiveness of these systems, but it is clear that if the policy guidelines will converge in the direction of Horizon 2020, the possibility of implementing such systems will become a model easily replicable and suitable. In this context, this work aims to show how a production system that exploits solar energy, through a plant collector, can be comparable in terms of cost with other energy sources. In particular, an estimate is made of an economic system with solar collectors for the production of electrical energy, starting with the year of production and on the basis of 25 years of life of the plant.
