The INEA and INCEA solar funding lines described on our grants page are suspended because their budgets are exhausted. No official reopening date has been confirmed. Reviewed 28 October 2026.
Energy savings, tax relief and public grants are different. We provide technical documentation for your project; your tax adviser should assess the relief available in your circumstances. Owning a property in Spain does not automatically make you eligible for Spanish IRPF relief.
Eligibility depends on the property, work and your Spanish tax position. The 2026 self-consumption relief is 10% or 20%, on an annual eligible-cost base capped at €5,000, with installation completed and paid for in 2026, a CIE electrical certificate and other requirements. Separate 20%, 40% or 60% energy-efficiency relief requires certified improvements using before-and-after energy certificates and has its own limits and deadlines. Both routes cannot be combined for the same installation in the same property. Solar panels alone do not guarantee tax relief.
| Route | Main requirement | Maximum eligible-cost base | Deadline |
|---|---|---|---|
| 10% self-consumption | System in a property you own; CIE, permits and other conditions | €5,000/year | Installation and payments completed in 2026 |
| 20% self-consumption | Owned home in a predominantly residential building; CIE and other conditions | €5,000/year | Installation and payments completed in 2026 |
| 20% efficiency | Heating/cooling demand at least 7% lower, certified before and after | €5,000/year | Work, payments and final certificate by 31 December 2026 |
| 40% efficiency | Non-renewable primary-energy use at least 30% lower, or energy class A/B, certified before and after | €7,500/year | Work, payments and final certificate by 31 December 2026 |
| 60% building renovation | Predominantly residential building: non-renewable primary-energy use at least 30% lower or class A/B, with building certificates | €5,000/year; €15,000 total | Work, payments and final certificate by 31 December 2027 |
The claimant must meet Spanish IRPF requirements. This is not a direct grant or a guaranteed invoice discount. Cash payments are excluded and granted subsidies must be deducted from eligible costs. Self-consumption relief requires a CIE electrical certificate and permits; this is different from the energy-performance certificates (CEE) required for efficiency relief. Business-use exclusions and other property conditions apply.
Keep invoices, bank-payment records, the CIE, permits and grant documentation. For energy-efficiency deductions, arrange the energy certificate before work begins and the certificate after completion.
Reviewed 28 October 2026: INEA Programme 1 residential solar funding is suspended under BOJA 23 October 2026. The solar budget lines of INEA Programme 2 (business and agri-food) and INCEA Line 2 Programme 3 (industrial value chains) are suspended under BOJA 2 October 2026. The resolutions set no reopening date. This does not mean every activity in both programmes is closed. We do not advertise these solar lines as available or deduct an unawarded grant from your quotation.
Some municipalities retain IBI or ICIO relief, subject to their current local ordinances. Mobility grants and other measures have separate calls and budgets; availability and awards must not be assumed.
The full legal requirements take precedence over this summary. We check status and documentation before including incentives in a study. Your tax adviser should review your personal eligibility.
We prepare installation documents and explain which records your adviser may need. Grant applications depend on an available funding call and its requirements; awards and payment cannot be guaranteed.
