The cost of electricity
Andalusia's grants for solar panels with batteries ran out in a day: what is left in 2026
At 9:00 on 22 October the Junta de Andalucía opened grants of up to 65% for installing solar panels with a battery at home. By the next day the line had been suspended because the budget had run out. Here is what happened and, above all, what you can still take advantage of if you live in Marbella, Estepona or anywhere on the Costa del Sol.
The call belongs to the "Residential sector and public buildings" programme of the Andalusian Energy Agency, published in the BOJA on 25 September. It had €20.77 million, co-financed with EU FEDER funds, and the solar line for homes was generous: a 55% incentive for private individuals, rising to 65% in some cases, such as collective self-consumption or municipalities facing depopulation.
There was one key condition: the battery was mandatory. Panels alone did not qualify. Panels and battery had to be part of the same investment, with a maximum of 5 kWh of battery per kW of panels, as reported by Energías Renovables.
The problem is that the money flew. A resolution dated 22 October suspends the lines worth €9.77 million because the allocated budget was exhausted. According to the press, the solar line for homes had €5.8 million and was covered by the applications filed on the first day (Qué!).
Can you still apply?
Today, for panels with a battery on a home, no. That line is suspended and does not accept new applications.
But suspended is not the same as closed for good. The resolution itself leaves the door open to reactivating it if the Junta increases or redistributes the budget. Grants are awarded first come, first served, not by project quality: when the money runs out, it stops.
What remains open, according to the published information, is the energy-efficiency line for homes, with around €11 million: insulation, heating and cooling, hot water and lighting, as long as the works raise the home's energy rating by at least one letter. A heat pump (aerothermal) for climate control or hot water may fit there. Applications go through the Andalusian Energy Agency's incentives portal.
Our advice: if you were planning a battery counting on this grant, do not put it on hold waiting for a reopening. Nobody knows whether there will be more money, or when.
Grants are handed out first come, first served: when the budget runs out, they are suspended.
What you can still use in 2026
Even if you missed the Junta's grant, there is a new income tax deduction that few people know about yet. Royal Decree-law 7/2026 created a 10% IRPF deduction for installing renewable self-consumption on a property you own, batteries included, on a maximum base of €5,000 a year. The Spanish Tax Agency explains it on its website.
The small print matters: it covers what you pay between 1 January and 31 December 2026, and the installation must be finished this year. The clock is ticking. We go through it step by step in our article on the deduction.
On top of that, many Costa del Sol councils offer a reduction on ICIO (the building works tax) and some on IBI (property tax). It depends on each local bylaw, so we check it case by case.
How we approach it
At Sun System we run the numbers without counting on grants. If an installation only pays off thanks to a grant that may never arrive, we will not recommend it.
With electricity almost free at midday and expensive in the evening, a battery makes more sense today than two years ago, with or without a grant. We explain why in our article on batteries versus selling your surplus.
If you want to know how much you would save at home, send us an electricity bill and we will prepare a free study. If the Junta reactivates the call, we will update this article.
