Does it cover panels and a battery?
The residential solar line requires new equipment and storage. The base incentive is 55% for households, the self-employed, micro and small firms. It can rise by up to 10 points.
Andalusia · 22 Oct 2026 – 30 Sep 2027
Grants for solar and batteries in Andalusia.
The Andalusian Energy Agency has opened the residential programme under the INEA order. €20.77 million, co-financed by ERDF. From 09:00 on 22 October 2026 until 30 September 2027, or until the money runs out.
Which percentage applies
25% to 80% across the whole programme. Solar with storage uses a different base.
| Household | Self-employed and small | Medium | Large | |
|---|---|---|---|---|
| Solar with storage | 55% | 55% | 45% | 35% |
| Home efficiency | 50% | 45% | 35% | 25% |
| Public building | — | — | 70%, or 30% if there is economic activity | Up to 80% with renewables |
Solar: up to 10 extra points for an energy community, collective self-consumption, an energy-service company, or a demographic-challenge municipality. Home efficiency: a household can reach 65%; the self-employed and companies, up to 15 extra points.
What fits an AIRVOLT system
The residential solar line requires new equipment and storage. Panels without a battery do not qualify on that line. Powerwall is the storage. A Wall Connector on its own is not what this call funds. A project with solar and a battery is.
Who can apply
Households, owners’ communities, renewable-energy communities, the self-employed, companies and energy-service companies. Town halls too, for public buildings.
Minimums
For residential solar, the incentive requested must reach €6,000. For other measures, €10,000. At 55%, €6,000 implies an eligible cost of about €10,900. That is orientation, not an agency cap.
If work has already started
A private household with no business activity can apply for work already under way, if it did not start before 1 May 2025. The self-employed and companies cannot have spent or committed anything before they apply.
Advance
Above €15,000 of incentive, an advance of 15% is possible with no guarantee, or 40% with a bank guarantee. A partial payment of up to 50% is also possible once that share of the investment is documented.
How to apply
Online, in order of arrival. There is no competition on merit: earlier files are served first, while budget remains.
incentivos.agenciaandaluzadelaenergia.esIs 80% for a house?
No. The programme spans 25% to 80%. 80% sits with public buildings when renewables are added to a 70% base. A home starts at 50% for efficiency, up to 65%. Solar with a battery starts at 55%.
Until when?
From 09:00 on 22 October 2026 until 30 September 2027, or sooner if the €20.77 million runs out.
Does AIRVOLT file the grant?
We prepare the system: study, solar and Powerwall, so the application has a real project. The Agency decides.
Source: Andalusian Energy Agency, call for the residential and public-buildings programme (INEA order of 24 April 2025), official gazette. AIRVOLT ENERGY S.L. does not award the grant and is not the Agency. The final percentage depends on the applicant and the intensifiers. Nothing is awarded until there is a decision.
