Self-consumption and Spain's Sun Tax

Do people know what self-consumption is and what it means?

While it is true that there is a regulatory framework of Royal Decree 900/2015, which establishes the administrative, technical and economic conditions that govern the supply of electricity with self-consumption, it is no less necessary that many changes are required to promote the advancement of renewables in our country. Changes and perhaps the formal repeal of the so-called "Sun Tax" would be the most necessary. The administrative processes in Spain to register the facilities are aberrant and in this case we have been their patient sufferers. For against the last area of ​​the world to give us new news about the imminent revolution and implementation of the changes that are about to come concerning renewable energies is California, where the Energy Commission has approved new regularizations that include the obligation that new houses have some type of solar energy by 2020. It is true that this law will have its exceptions as all, these being for example those buildings that can not fit in the panels or that are hidden from the sun, for which it is not feasible to include the solar panels in both cases. It is estimated that this new measure will increase the construction cost around $ 25,000 and $ 30,000, taking into account that it is estimated that the energy produced by these panels will save the owners between $ 50,000 and $ 60,000 in operating costs throughout the year. the 25 years of expected life of solar technology. "All new homes in California will have solar panels. The rich, the poor, the flats, the chalets ... All. Simply because the mortgage increases by $ 40 while saving 80 on the electricity bill.

" In Spain it is not sunny. https://t.co/1QCQdmg6fW ".

In recent years, all European reference countries have worked hard to design sustainable and responsible energy policies, with Germany being one of the leaders in the field, where, with 30% less solar irradiation than Spain, generation has been promoted photovoltaic, which accumulates approximately 34,850 MWn installed, compared to 4,674 MWn with which we have in our country. In Spain, the action consisted in maintaining the fossil generation model and the price formation system in the wholesale market and in destroying photovoltaic social production, thus boosting the legal security and prestige of Spain as a safe place for investments , with the result described above: high energy prices and three dozen resolutions pending resolution at the World Bank, which could charge up to 7,000 million Euros in addition to the electricity bill. The only ones favored were the large companies in the sector, which have not suffered any consequence of the serious economic depression of recent years in their income statements. If in Spain we had the same photovoltaic power installed in Germany, which amounts to almost 35 GW, thanks to the greater solar radiation our territory receives, we could generate around 55,000 GWh, which would mean a reduction in the pool price of our energy of 36 %. The building sector is key in meeting the objectives of greenhouse gas emissions of the European Union, and the directive of energy efficiency in building marks clear objectives in this aspect, demanding design of new energy buildings "almost zero from 2020".

Our pioneer example of an isolated single-family house located in Valdemarín (Madrid-Spain) was designed in 1987 according to criteria of energy efficiency, use of renewable energy and sustainability; it aims to provide maximum comfort to its inhabitants with the minimum energy consumption and this is already more than thirty one years.
