One of the factors that most reduces the real cost of a solar installation is the public incentives and tax deductions available. In Andalusia, in 2026, there are three levels of support that can be combined. Here's a summary; you'll always find the updated details on our tax incentives page.
The deduction for energy-efficiency home improvement works applies in three tiers (20%, 40% and 60% of the investment), depending on the type of work and the energy rating improvement achieved. The 60% tier is the most common for photovoltaic installations on single-family houses, with tax savings that can reach €3,000 a year. It requires an Energy Performance Certificate before and after the work.
Each city council decides whether to offer rebates on property tax (IBI) and on the construction/works tax (ICIO). In Malaga city, for example, there's a 15% IBI rebate for 3 years and up to 95% on ICIO for non-profit self-consumption installations. If your installation is in Marbella, Mijas, Fuengirola, Benalmadena or Granada, conditions may vary — we can help you check before quoting.
The Junta de Andalucía channels its self-consumption incentives through the INEA programme (Incentivos para el Uso Eficiente de la Energía en Andalucía). The line for businesses and the self-employed has been open since November 2025; the line for private houses is pending publication in the Andalusian Official Gazette (BOJA), with opening expected during 2026. We'll let you know as soon as it opens.
This guide is for informational purposes and summarises the general situation as of August 2026. The exact requirements, deadlines and percentages can vary depending on your personal circumstances (primary residence, rental, business) and regulatory changes. We recommend confirming the details with a tax advisor before making decisions, and counting on us for the technical documentation usually required (Electrical Installation Certificate, installation certificates).
