If you live in a residents' association and you have ever toyed with the idea of installing solar panels on the communal roof, this is the definitive moment to take the step.
The 60% deduction for installing solar panels on residential buildings has been extended to 2027.
Royal Decree-law 16/2025 has just been published in the Spanish Official Gazette (BOE), bringing excellent news for household savings: the "strong" 60% IRPF (income tax) deduction for energy refurbishment of residential buildings has been officially extended until 31 December 2027.
While other aid for single-family homes has shorter deadlines, the Government has decided to give residents' associations two extra years of breathing room. At Atodosol we explain why this is the biggest tax opportunity of the decade for your building.
What exactly does this 60% deduction consist of?
This is not a subsidy that takes years to arrive — it is a direct deduction on your income tax return.
Unlike minor works in individual homes, the deduction for energy-renovating an entire building lets each resident write off 60% of the share of the photovoltaic investment that corresponds to them.
A practical example: if the share for the solar installation in your building costs you €6,000, you could recover €3,600 directly on your next income tax return. The real net investment ends up dramatically reduced, making it the cheapest way to switch to collective self-consumption.
The requirements: what does your building need to meet?
For the Spanish tax authority to validate this deduction, the rules set clear technical criteria:
- Consumption reduction: the works must achieve at least a 30% reduction in non-renewable primary energy consumption in the building.
- Improved energy rating: it is also valid if the building reaches energy class "A" or "B" after the installation.
- Investment limit: the maximum annual base on which the 60% applies is €15,000 per taxpayer, much higher than in previous years.
At Atodosol we take care of the prior technical study and the necessary certificates to make sure your association meets these requirements before a single screw is turned.
Why you should not wait until 2027
Although the extension gives us breathing room until the end of 2027, waiting is not a good strategy for a residents' association for three reasons:
- The administrative timeline: from the moment you commission the study, debate it at the AGM, approve the contribution and execute the works, several months can go by.
- Immediate savings: the sooner you install the panels, the sooner you start cutting the communal electricity bill (lifts, lighting, garages, etc.).
- Market saturation: as the 2027 deadline approaches, demand for installers will be massive. Being among the first guarantees an installation with no waiting times and the best materials available.
