Feasibility analysis of a photovoltaic system: the importance of expectations

At present, problems such as climate change and pressure on ecosystems require profound changes at the economic and social levels. One of the most critical areas is energy generation, in order to reduce greenhouse gas emissions and dependence on non-renewable fossil fuels. In this context, this paper analyses, from a purely economic perspective, the viability of an investment in a domestic photovoltaic system, presenting three future scenarios. Results show how the legal context has great importance in the profitability of the project and, therefore, in the decisions of the economic agents.
