Grants and subsidies for the installation of solar panels in Girona

In 2025, the residents of Girona can access a wide range of subsidies, tax credits and deductions that significantly reduce the cost of installing solar panels. Here we explain what subsidies are available, how to apply for them and how much you can save.
Local grants from Girona City Council
IBI rebate for solar installation
The City Council of Girona offers a 50% rebate on the IBI for 5 years for those homes that install solar panels on a voluntary basis (not mandatory by law). This help can save up to 317,65 € per year.
ICIO rebate
A 95% rebate is applied in the Tax on Constructions, Installations and Works (ICIO) for self-consumption photovoltaic installations. This saving is applied when processing the building permit or responsible declaration.
Urban Development Tax Rebate
In most cases of residential solar installations, the fee for minor building permits is reduced by up to 100%. This means that you can install solar panels on your roof without paying municipal planning fees.
State and autonomous community aid applicable in Girona
Next Generation Grants
The Next Generation European funding program has subsidized thousands of solar installations throughout Catalonia. For installations of up to 10 kWp, the aid has been up to 600 €/kWp. A new call for proposals is expected in 2025, so it is advisable to have the project ready.
Personal income tax deduction for energy efficiency
You can deduct up to 20% of the cost of the installation in your income tax return, provided that you achieve an energy improvement of at least 7% and present the energy certificates before and after. Applies only to primary residence.
