See the explanationWe add new material constantly. Here are the topics we cover, organized by category.
The Casa Verde programme, run by AFM, funds the switch to green energy through a voucher. Important for 2026: the classic Casa Verde Fotovoltaice line (new systems) has not been reopened — the active programme is Casa Verde Baterii (storage), with a voucher of up to ~15,000 lei for existing prosumers, and AFM has signalled the guide and registration sessions for autumn 2026. In short, how to apply: you are (or become) a prosumer with an ANRE certificate, you choose an AFM-validated installer, you have no debts to the state budget, and the file is submitted through the AFM platform (usually handled by the installer). Always check the official conditions at afm.ro.
