Most citizens would like to save money on the electricity bill and be able to generate green energy in our own homes to consume it directly. So, why do not you see more roofs with solar panels for self-consumption? The answer lies in misinformation , on the one hand, and confusing information , on the other. With this entry we will try to throw a little light on all this “tinglado” and, thus, encourage many citizens to bet on self-consumption.
Self-consumption and storage are legal in Spain
The sun tax affects only those self-consumption facilities that exceed 10 kW. This means that only 2% of Spaniards are affected , 98% of households would not be obliged to pay the sun tax . However, the installations of solar panels have fallen since the incorporation of the regulation that includes this tax. This is because in addition to the tax, the law puts a series of difficulties and great bureaucracy that make it difficult to decide. Among them we find the amount of papers that must be completed: technical report, application for connection permits to the company, have a line and a specific automatic, pay connection fees and hook, install a second counter along with the one that already has the housing, etc. Calm down, at SotySolar we do all this for you!
All this, supposes a cost, economic and in time, of which the majority of the Spaniards does not have. Therefore, despite the fact that the price of electricity has risen around 70% in the last 10 years, we did not decide to install solar panels for self-consumption.
You could say that in Spain is sanctioned for doing the right thing, instead of facilitating the installation of solar panels in homes and take advantage of an abundant resource in Spain, the sun, there are impediments for it. Citizens are aware, and most of them would like a change in energy production towards a more renewable and sustainable way, but not only are they not helped to carry it out, but impediments are placed on it.
What happens if we install solar panels and generate energy that we do not consume?
If we generate surplus energy in our installation of solar panels for self-consumption, we have 3 options: to waste it, sell it or store it in batteries . In the first case, it is not logical to think that while some households can not afford to pay the bills of light, in other homes, energy is thrown away. The second option, to sell this energy , that is to say, that the company makes a net balance , seems the most logical, since you would get some income and it would be taking advantage of it, but again we go back to the bureaucracy, the amount of papers that must be done to allow you to sell it (you have to register in some registers, etc.) makes it unprofitable, since the sale will not be a high income. The last option, the use of smart batteries , is being applied in some homes, even if they have completely disconnected from the network. At night they take advantage of the energy generated by the solar panels during the day and that they have not used. These batteries , today, increase the cost of the initial investment, take up a lot of space, and are not very ecological, although they are still being developed and these inconveniences may disappear in the future.
Spain stopped betting on renewables, but what have other countries done?
A photovoltaic panel in Spain provides 49% more energy than one in northern Europe thanks to the climate. Most developed countries are committed to self-consume electricity, without going further, in Portugal the regulation favors it, for small self-consumption facilities you just have to register on a website. Although Europe enjoys its holidays in Spain by the sun, in solar self-consumption facilities we are behind Italy, France, United Kingdom and Germany. The installed power in Germany is 8 times that of Spain, since the government promotes the installation of solar panels in homes , for example. Of the 100 GW installed in Europe, only 5% corresponds to Spain.
To make clear how the legislation has affected self-consumption, in 2008 Spain was the world leader in installed power in photovoltaics, however, cuts to renewables (the first in 2010 and the second and strongest in 2011) have reversed this situation now Spain is a very small target for photovoltaic solar energy companies. Most have disappeared or left Spain. As an example, in 2015 the United Kingdom, a country characterized by its cloudy days, installed in the order of 3500 kW, while Spain, where sunny days abound, only 49 kW.
Shared self-consumption is already possible
But not everything is bad news. Recently, the Constitutional Court has annulled the government’s prohibition on shared self-consumption . The TC gives the reason to the Generalitat de Catalunya that filed an appeal against the Royal Decree for invasion of autonomous powers. The prohibition affected neighboring communities, preventing them from sharing self-consumption generation facilities.
The photovoltaic is profitable by itself , does not need subsidies, only that citizens have the initiative to install solar panels . From the legal side, obstacles and paperwork existing today we take care of ourselves.
