Solar Incentives in Italy 2026: Tax Deductions, GSE Schemes & Energy Communities
Last updated July 2026
Italy supports solar mainly through income-tax deductions for renovation and energy-efficiency works (with the enhanced Superbonus being wound down), plus GSE-run schemes such as Conto Termico 3.0, the Reddito Energetico for low-income homes, and renewable energy communities (CACER). The historic Conto Energia feed-in tariff is closed. Every plant is registered in Terna's GAUDÌ. Verify current terms at the official source.
Italy supports residential and commercial solar mainly through a mix of national tax deductions and incentive schemes administered by the state-owned energy services operator GSE (Gestore dei Servizi Energetici), alongside the tax authority Agenzia delle Entrate for building-renovation and energy-efficiency deductions. Over recent years the framework has shifted away from the historic feed-in tariff (Conto Energia, closed in 2013) and legacy net-metering (Scambio sul Posto, now closed to new systems) toward self-consumption, energy sale to GSE (Ritiro Dedicato), collective self-consumption and renewable energy communities (CACER), and targeted grants such as the Reddito Energetico for low-income households. Because rates, budgets and eligibility windows change frequently and some schemes operate on a first-come or limited-fund basis, current terms should always be verified at the official source before relying on them.
Registering your solar system on the grid
GAUDÌ (Terna national plant registry), with connection via the local DSO and incentives via GSE
Every generating plant, including rooftop PV, must be registered in GAUDÌ, the national plant registry operated by the transmission system operator Terna, which assigns a census (CENSIMP) code. Physical grid connection is handled by the local distribution system operator (DSO), most commonly e-distribuzione, while access to incentive and energy-valorisation mechanisms is managed by GSE. Registration is a mandatory prerequisite to be recognised as a producer and to access mechanisms such as Ritiro Dedicato.
Renovation & energy-efficiency tax deduction (Ristrutturazioni / Ecobonus)
Administered by: Agenzia delle Entrate (Italian Revenue Agency)
A personal income-tax (IRPEF) deduction spread over several annual instalments for building-renovation and energy-efficiency works, under which installing a photovoltaic system (and associated storage) can qualify as an eligible measure. It is the most broadly used route for households investing in rooftop solar as part of home improvement works.
Who it is for: Individuals liable for Italian income tax who carry out qualifying renovation or energy-efficiency works on residential property they own or hold, with a distinction typically drawn between a primary residence and other properties; the rate, ceilings and conditions must be verified at the official source.
Superbonus
Administered by: Agenzia delle Entrate (with technical/energy data transmitted to ENEA)
An enhanced tax relief for deep energy-efficiency and seismic retrofits of buildings, within which photovoltaic and storage could be included as ancillary measures. The scheme is being wound down: its enhanced rate has been progressively reduced and it is closing to most new interventions, with only narrow residual cases (such as buildings in designated earthquake-crater areas) still eligible; households increasingly rely on the ordinary renovation and energy-efficiency deductions instead.
Who it is for: A restricted set of beneficiaries and building types under tightening conditions, subject to the specific residual cases still admitted; because the rate trajectory and eligibility are changing, current status must be verified at the official source.
Conto Termico 3.0
Administered by: GSE (Gestore dei Servizi Energetici)
An incentive scheme that reimburses part of the cost of small-scale energy-efficiency and renewable-heat interventions, in which photovoltaic can be incentivised when installed together with qualifying measures such as replacing a heating system with an electric heat pump. The current version, Conto Termico 3.0, updated the operating rules, eligible measures and beneficiaries.
Who it is for: Public administrations and, for non-residential/tertiary buildings, private entities; eligibility for PV in particular is tied to being carried out jointly with specific efficiency measures, so scope and beneficiary categories should be checked at the official source.
Reddito Energetico Nazionale (National Energy Income)
Administered by: GSE (Gestore dei Servizi Energetici)
A national capital-grant fund that finances the installation of small domestic rooftop photovoltaic systems for lower-income households, designed so the system operates in self-consumption mode. It operates on a first-come basis while fund resources last, with energy not self-consumed ceded to GSE.
Who it is for: Individuals in households in a condition of economic disadvantage, identified by an income indicator (ISEE) below defined thresholds, installing a domestic residential PV system within set power limits; thresholds and fund availability must be verified at the official source.
Renewable energy communities & collective self-consumption (CACER)
Administered by: GSE (Gestore dei Servizi Energetici), under a decree of the MASE (Ministry of Environment and Energy Security)
A framework that supports electricity produced by renewable plants shared within renewable energy communities, groups of self-consumers, or remote self-consumption configurations, combining an incentive tariff on shared energy with, in defined cases, a capital grant funded partly by the national recovery plan (PNRR). It is the main route for communities and collective self-consumption arrangements involving solar.
Who it is for: Members of eligible self-consumption configurations and renewable energy communities — which can include households, businesses, public bodies and local authorities — subject to plant, location and configuration rules; specific conditions and any capital-grant geographic limits must be checked at the official source.
Before you rely on any figure — check the official source
Solar incentive rates, tariff levels, budgets, eligibility thresholds and deadlines in Italy change frequently, and several schemes run on limited budgets or fixed application windows. This guide describes each programme at the mechanism level and links to the official administering body so you can confirm the current terms for your own project and year. Never commit to a purchase on the strength of a headline number from a third-party site — including this one.
Once you know which schemes apply, the practical next step is a qualified local installer who can size the system, handle the grid registration and apply for the incentives that fit. Browse solar companies in Italy → on Solar Directory.

Frequently Asked Questions
Who administers solar incentives in Italy, and how is a system registered on the grid?
expand_more
Most solar incentive and energy-valorisation schemes are administered by GSE (Gestore dei Servizi Energetici), while tax deductions for renovation and energy-efficiency works run through Agenzia delle Entrate. Physically connecting a system is done through the local distribution system operator (DSO, most often e-distribuzione), and every generating plant must be registered in Terna's national GAUDÌ registry, which assigns a census code that is a precondition for accessing GSE mechanisms.
Is Conto Energia still available, and what happened to net metering?
expand_more
Conto Energia, Italy's historic feed-in tariff for solar, is closed and has been for over a decade — it no longer accepts new plants and exists only as legacy contracts. Scambio sul Posto (net metering) has likewise been closed to new systems and is being phased out; new producers instead typically use self-consumption, sell surplus energy to GSE through Ritiro Dedicato, or participate in collective self-consumption and energy-community configurations. Confirm the current mechanisms and their status at the official GSE source.
Can a household still get a tax deduction for installing solar panels?
expand_more
Yes — installing photovoltaic panels (and often associated storage) can qualify as an eligible measure under the building-renovation and energy-efficiency tax deductions administered by Agenzia delle Entrate, generally recovered over several annual instalments. The enhanced Superbonus is being wound down, so most households now rely on the ordinary renovation/energy deductions; the applicable rate, ceilings and eligibility should always be verified at the official source.
