Abstract
This paper analyses the new Spanish normative on self-consumption (Royal Decree 900/2015) and its effects and profitability depending on the consumption profiles. A model based on the discounted cash flows over the life cycle of the plant model is used to analyze the feasibility of a photovoltaic system of self-consumption. The impact of the Royal Decree in the return on investment of a solar photovoltaic system of self-consumption is discussed for three different types of consumers, analysing the effect of the charges associated with the costs and services of the electrical system. In each case solutions are proposed to improve the viability and they are simulated with alternative regulatory schemes such as net metering. Finally, the effect of the difference in electricity production between two Spanish cities like Seville and Oviedo with very different climatic conditions is analyzed.
