New edition of the PV subsidy for 2025
Status: 07.07.2025
In summer 2025, the program for the promotion of solar systems in the city of Aachen will enter its next round.
Funding will be provided for photovoltaic systems and electricity storage systems for apartment buildings as well as roof reports and photovoltaic systems for SMEs (small and medium-sized enterprises as defined by the EU).
Please note that funding is not provided for plug-in solar modules (balcony power plants) or PV systems on detached and semi-detached houses.
In order to shorten waiting times in the funding programme, the processing procedure has been intensively revised and digitized in recent months. The final internal checks are currently being carried out so that applications can be opened in the coming weeks.
Please note that systems that are commissioned before the application is submitted in the funding program cannot be funded! The funding guidelines and all other information will be made available here in due course. Until then, we will be happy to answer your questions using the contact details below.
