Ayudas y Subvenciones para Instalar Placas Solares - IBERDROLA

Spain is one of the countries in Europe with the most hours of sunlight. This is a fact that we can and must take advantage of to continue fighting climate change and change our energy model. With this goal in mind, the government's latest move was to approve a plan for grants last June that will change the rules of the game and boost self-consumption in the regions over the next two years. These will be used to implement programmes with incentives linked to self-consumption and storage and with renewable energy sources, as well as for the implementation of renewable thermal systems in the residential sector, within the framework of the Recovery, Transformation and Resilience Plan (RTRP).

Within this roadmap, six incentive programmes for self-consumption, storage and thermal uses of renewable energies were also approved. This project will be endowed with a combined initial amount of €660 million to be financed with funds from the Recovery and Resilience Mechanism.

While this strategy is being implemented, for now the State Housing Plan 2018-2021 is in force, which establishes the regulation of energy efficiency and sustainability. In other words, applied to self-consumption, it allows the possibility of applying for grants for the installation of solar panels in homes and buildings. Each autonomous community sets the specific requirements for accessing them.

These grants are a key factor in determining how long it may take for a household to pay back the investment. That is why it is so important to know about them. The closing date of the call is 31 December 2023.

Broadly speaking, the subsidies available are divided into two: those applied to the cost of installation and those applied to taxes. As for the latter, there are rebates for the Property Tax (IBI) and the Construction, Installations and Works Tax (ICIO), as they are municipal taxes, these grants vary according to the town council. IBI can be subsidised for several years, with a maximum 50% subsidy. On the other hand, the ICIO is a one-time tax, so it can only be subsidised once.

These are the grants, rebates and subsidies offered by the 17 autonomous communities for the installation of solar panels:

Andalusia

Subsidies on the price of the installation: up to 90% of the total eligible costs: this depends on the action and the type of beneficiary (there are three types of incentive lines: sustainable construction, SMEs and smart grids).
Grants: up to 50% of the IBI tax for a period of time ranging from 3 to 30 years, depending on the province.
