Agenzia delle Entrate
The increased principal-residence rate depends on ownership or a qualifying real right, use as the principal residence, eligible work, correctly traceable payment, documentation and sufficient Italian tax capacity. A tax adviser or CAF should confirm the personal tax position.
Autonomous Province of Bolzano
Provincial contributions are normally application-based and must be assessed before work starts. Technical thresholds, eligible costs, deadlines, product origin and the relevant applicant category matter. The 2026 window referred to here ended on 31 May 2026.
GSE
PV and storage are not automatically supported as stand-alone measures. Under the relevant route, they must in particular be combined with replacement of an existing heating system by an electric heat pump and operated for self-consumption under the GSE’s rules. PV, heat demand and storage therefore need joint design.
MIMIT / Invitalia
The national framework defines percentage and cap values, but access depends on the applicable decree, eligible expenditure and an open application window. Equipment conformity, invoices and traceable payment documentation must be prepared correctly.
Project support
The public authority, GSE or tax administration decides recognition and payment.
