Subsidies for the installation of solar panels and storage in residences are regulated by Royal Decree 477/2021, which allows the autonomous communities to grant these subsidies in order to promote the deployment of renewable energies.


660 million euros.

However, it could be extended if there is budget availability for the same purpose, and provided that the term has not expired.

Period of validity:

applications may be submitted until December 31, 2023.

Aid scheme:

the aids are granted through simple concurrence, i.e., they are studied/awarded in strict order of presentation until the funds are exhausted.

Individuals who carry out some economic activity by which they offer goods and/or services in the market.
Communities of owners on horizontal property.
Renewable energy communities and citizen energy communities, provided that they do not carry out any economic activity by which they will exploit goods and/or services in the market.

Amount of the aid:

the amount of the aid to be granted will be the sum of the Base Aid and the Additional Aid, which may correspond in each case.

For the incentive programs corresponding to the residential sector, the amount is summarized as follows:

Photovoltaic Installation Self-consumption: 300 – 600 €/*kWp
Incorporation of Self-consumption Storage: 140 – 490 €/kWh

Additional aid for demographic challenge: these subsidies are granted to homeowners living in municipalities with up to 5,000 inhabitants and in non-urban municipalities with up to 20,000 inhabitants, in which all of their singular population entities have up to 5,000 inhabitants. The additional amount to the subsidy is €50/*KwP.

IBI rebate

Some municipalities in Catalonia

Apart from the subsidy granted by IDAE, there is a list of municipalities that have approved a system of rebates in the Real Estate Tax (IBI) for those homes that incorporate a photovoltaic panel installation.

We share with you a interactive map of Catalonia by the National Association of Self-consumers The information on this bonus system is collected from all those municipalities with more than 1,000 inhabitants.

The IBI rebate does not affect the subsidy granted by IDAE, since it is not understood as a subsidy.


ICIO rebate

Some municipalities in Catalonia

On the other hand, some municipalities have also approved a system of bonuses in the Tax on Constructions, Installations and Works (ICIO) for those constructions that incorporate an installation of photovoltaic panels.

This bonus can be as high as 95%. in favor of the constructions, installations or works to which a solar self-consumption installation is incorporated.

The ICIO Bonus does not affect the subsidy granted by IDAE, since it is not understood as a subsidy.

Personal income tax information

Personal income tax

*With the energy certificates from the client and the Eltex invoice, tax deductions on the IRPF can be obtained.

People who install solar panels in their homes will be able to take a series of tax deductions in the Personal Income Tax (IRPF), included in the Royal Decree 19/2021.

As a general rule, these deductions for installing photovoltaic self-consumption systems may be applied for in any dwelling, whether it is for residential or rental use.

The deductible amount can be 20%, 40% or 60% depending on the percentage of non-renewable primary energy that is reduced as long as a series of requirements are met, such as improving the energy rating of the home or reducing the consumption of non-renewable energy.

With Eltex you won't have to worry about a thing.
We take care of applying for all grants and subsidies.
