Spain IRPF Personal Income Tax Deduction for Solar Panels
Agencia Estatal de Administraci贸n Tributaria (AEAT)
Active
20-60% tax deduction (up to EUR 5,000/year, max EUR 15,000 total)

Spain offers personal income tax (IRPF) deductions of 20% to 60% for residential solar panel installations, regulated by Royal Decree-Law 19/2021. Three tiers exist: 20% deduction for projects reducing heating/cooling demand by at least 7% (primary residence only), 40% deduction for projects reducing non-renewable primary energy consumption by 30% or achieving energy class A or B, and 60% deduction for full energy rehabilitation of residential buildings. The annual deduction cap is EUR 5,000, with unused amounts claimable over the next four tax years up to a total of EUR 15,000. Pre- and post-installation energy efficiency certificates are required. The Spanish government extended these deductions through 31 December 2026.

Spain Self-Consumption Compensation (Excedentes)
Ministerio para la Transici贸n Ecol贸gica y el Reto Demogr谩fico
Active
Surplus energy compensated at wholesale market price (~EUR 0.05-0.10/kWh)

Under Royal Decree 244/2019, Spanish households and businesses with solar self-consumption installations can receive financial compensation for surplus electricity exported to the grid. The compensation is applied as a credit on the electricity bill, offsetting the variable energy charges (but not fixed charges or taxes). The scheme supports both individual and collective (shared) self-consumption configurations, allowing apartment buildings and neighbouring properties to share a single solar installation. Spain's self-consumption regulations were significantly simplified in 2018-2019 after the repeal of the controversial 'sun tax' (impuesto al sol), making distributed solar economically viable.

IDAE Innovative Renewable Energy Program (Next Generation EU)
Instituto para la Diversificaci贸n y Ahorro de la Energ铆a (IDAE)
Active
Varies by programme and region (original grants covered 40-65% of costs)

Spain's Institute for the Diversification and Saving of Energy (IDAE) administers grants funded by the EU NextGenerationEU Recovery Plan for innovative renewable energy projects, energy storage, and renewable thermal systems. Spain received EUR 660 million in initial NextGenerationEU funding for energy efficiency upgrades. While the original residential self-consumption grant programmes (Programmes 4-6) exhausted their budgets by 2024, IDAE continues to offer funding through the Recovery, Transformation, and Resilience Plan for innovative projects. Grants are channelled through the autonomous communities (comunidades aut贸nomas) and may vary by region. Availability depends on remaining budget allocations in each autonomous community.
