Subventions

For offers signed between the 1st October 2024 et 4th March 2026 and for which the final invoice must be issued no later than the 31st December 2026, a transitional phase applies during which two options are available:

• the former subsidy scheme, with a subsidy of 50% and a maximum of €1,250/kWc (self-consumption/energy community).

OR

• the new Klimabonus subsidy scheme, the full application of which is detailed in the section below ‘From the 5th January 2026’.

This framework applies a new calculation formula based on the installed power and, where applicable, the capacity of the installed battery, and gives you the choice between:

• submitting the application for assistance in the traditional way to the Environment Administration
• pre-financing using the same new calculation formula, subject to compliance with the pre-financing conditions.

It should be noted that from this period onwards, installations associated with a guaranteed feed-in tariff will no longer be eligible for a subsidy.

Finally, this scheme also provides a subsidy for the installation of a battery after the installation of a photovoltaic system.
