Subsidies

The Government has a subsidy plan for solar panels planned for the 2017-2020 period, which means covering the cost of photovoltaic installations by more than 80%, depending on the region.

But for this grant to be awarded there are a series of requirements and guidelines to follow, which are:

Install the photovoltaic system in municipalities with less than 20,000 inhabitants.
In the case of photovoltaic self-consumption connected to the electrical network or isolated, they must have a power greater than 5 kW.
Both projects must involve an investment between 50,000 euros and one million.
All these regulations are currently contained in Royal Decree 616/2017, which you can read here.

But not all the autonomous communities cover the same percentage of investment, since this varies according to what is established in the ERDF program. For example, in Madrid, Navarra, Catalonia, the Basque Country, Aragon or the Balearic Islands it covers 50%, while in Andalusia, Extremadura, Galicia or Asturias it covers up to 80%.

This program not only favors subsidies for solar panels in all its forms, but also favors geothermal energy, solar thermal energy, thermal fluid distribution networks or heat pumps.

Below we are going to show the updated guide until 2018 that shows the steps for houses or buildings to join self-consumption.

All this is favored thanks to the fact that last October the renewable energy sector celebrated the repeal of the sun tax through Royal Decree Law 15/2018, in which its greatest novelty is that it now favors collective self-consumption.

But so that we can begin to benefit from this type of installation, the first thing that IDAE (Institute for Energy Diversification and Saving) recommends is to make sure that there are no legal limitations to place the photovoltaic installation in the chosen place, and to For this, we must go to the urban planning department of the town where the installation is going to be placed. Generally, it is usual to request the design, the certificate and the execution of the installation, register in the autonomic registry of self-consumption and have a building license.

This type of installation will be seen more in certain places and its requirements will therefore be different.

VILLAS
This installation is carried out individually and requires an installed power of between 1.5 to 3 kW, which entails installing between 6 and 12 solar panels, that is, an estimated investment of between 3,000 and 6,000 euros.

BUILDINGS
It is a joint installation, so on this occasion IDAE recommends a simple assembly that covers the demand of the common areas that a community of neighbors may have, for example.

SME
In these companies, the installed power can exceed up to 15 kW and they should request an access point from the distribution company, which in some cases could lead to certain problems. The cost of this type of photovoltaic installation could reach around 50,000 euros, but the savings that it would mean on your bill could be up to 55%.
