People are still asking if self-consumption is legal in Spain and the answer is conclusive: it is not only legal but is also very cost-effective. As with every form of this type of installations, its economic benefits will depend on the features inherent to each, such as, for example, the consumption profile, weather conditions of the region or roof orientation. But we can safely confirm that self-consumption is here to stay and that it offers a very attractive option from the point of view of cost-effectiveness.
Forecasts for the renewable energy sector are excellent according to UNEF (the Spanish PV Industry Association), with between 450 and 600 MW per year expected to be installed for self-consumption alone. Moreover, looking back, we can see that this type of installations has tripled over the last two years, going from 57 MW installed in 2016 to almost 250 MW in 2018.
Fall in the price of solar panels
Over the last 7 years, the price of a solar panel has fallen by more than 80%. In addition, according to Bloomberg New Energy Finance, the cost per module is expected to continue to drop over the course of 2018 and 2019 by up to 35%.
And what about batteries?
This is currently the most expensive component of the installation. However, research in this sector is progressing at a dizzying pace and a new revolution is expected as regards batteries, with a significant price drop and the emergence of new technologies, driven in part by the automotive sector’s quest to equip electric vehicles with ever-greater autonomy.
Regulations in Spain
The outlook is very positive, following the approval of Royal Decree 15/2018, from which three significant measures can be highlighted:
• Elimination of the sun tax.
• The right to shared self-consumption, which opens such installations up to neighbourhood associations.
• Simplified administrative procedures
A draft Royal Decree law already exists, which regulates the administrative and technical conditions for connecting self-consumption installations to the grid. Here is a link to a video-lesson in which you can view an explanation of these regulations.
As a result of the volume of movement in the sector, MasterD is highly committed to promoting renewable energy and to disseminating good practices through key sector agents. Here you can view the seminar held at our offices on 3 April, given by the company SUMSOL.
