Solar Incentives in Greece 2026: Net Billing, Solar Rooftops & Grid Steps
Last updated July 2026
Greece supports solar through self-consumption (net billing is now the default for new connections, after net metering closed to most applicants in 2024) plus state grants — Fotovoltaika sti Stegi (Solar Rooftops) for households with storage, and a farmer scheme. Policy is set by ΥΠΕΝ; ΔΕΔΔΗΕ handles grid connection; ΔΑΠΕΕΠ settles. Confirm current rounds and terms officially.
Greece supports rooftop and small-scale solar mainly through self-consumption (αυτοπαραγωγή) arrangements plus a state grant programme for households and farmers. Following 2024 reforms, classic net metering (which offsets the kilowatt-hours you produce against those you consume over a settlement period) was closed to most new applicants, and net billing became the default framework for new connections: on-site consumption is offset in real time while any surplus fed to the grid is compensated at the wholesale market price under a long-term contract. Net metering now remains open only to defined groups such as municipalities and households certified as being in energy poverty. Policy is set by ΥΠΕΝ (the Ministry of Environment and Energy); ΔΕΔΔΗΕ (HEDNO) is the distribution operator that handles grid connection and metering; electricity suppliers and ΔΑΠΕΕΠ (the RES and Guarantees of Origin Operator) handle billing and settlement. The flagship grant, Φωτοβολταϊκά στη Στέγη (Solar Rooftops), co-funds household and farmer PV paired with battery storage in application rounds that stay open while budget remains, and a parallel scheme, Φωτοβολταϊκά στο Χωράφι (Solar in the Field), targets farmers. Programme rounds, eligibility rules and the net metering to net billing transition change over time, so always confirm current figures, rates, caps and deadlines at the official source before you apply.
Registering your solar system on the grid
Grid connection via ΔΕΔΔΗΕ (HEDNO)
Before a self-consumption PV system can be installed and energised, the producer applies to ΔΕΔΔΗΕ (HEDNO), the electricity distribution system operator, for grid connection. HEDNO reviews the application and issues a written Connection Offer describing the works required; once the applicant accepts and a Connection Agreement is signed, HEDNO carries out the connection and installs the bidirectional meter. A separate net metering or net billing contract is then concluded with the electricity supplier. Low-voltage household applications go to the local HEDNO regional unit, while larger or medium-voltage systems are handled by the competent HEDNO department, increasingly through an online platform.
Net billing self-consumption (αυτοπαραγωγή)
Administered by: ΥΠΕΝ framework; operated by ΔΕΔΔΗΕ, electricity suppliers and ΔΑΠΕΕΠ
The standard arrangement for new PV connections. Electricity generated is consumed on site and offset against consumption in near real time, while surplus exported to the grid is compensated at the prevailing wholesale market price under a long-term self-consumption contract. It replaced net metering for most new applicants, shifting the value of exports from an energy-for-energy offset to a market-price payment settled through the supplier and ΔΑΠΕΕΠ.
Who it is for: Households, businesses and farmers installing a new self-consumption PV system (with or without storage) who have a valid HEDNO connection and a supplier contract.
Net metering (legacy energy offset)
Administered by: ΔΕΔΔΗΕ (HEDNO) with the electricity supplier
The original self-consumption model, under which kilowatt-hours produced by the PV system are netted against kilowatt-hours consumed over a settlement period via a bidirectional meter. After the 2024 reforms it is no longer offered to the general public and continues to be available only for specific categories of applicant.
Who it is for: Now limited to defined groups such as municipalities and local authorities and households certified as being in energy poverty; confirm current eligibility with HEDNO and your supplier.
Φωτοβολταϊκά στη Στέγη (Solar Rooftops)
Administered by: ΥΠΕΝ (Ministry of Environment and Energy)
A state subsidy programme that co-funds the installation of small rooftop PV systems combined with battery storage for self-consumption. Applicants must already have a signed HEDNO connection agreement for the PV and storage system, then apply on the programme's online platform; applications are accepted in rounds while budget lasts, and project completion deadlines have been extended in the current round.
Who it is for: Natural persons (households) and, under related terms, farmers meeting the programme's income and property eligibility criteria; check the official guide for current conditions.
Φωτοβολταϊκά στο Χωράφι (Solar in the Field)
Administered by: ΥΠΕΝ (Ministry of Environment and Energy)
A subsidy scheme that helps farmers install PV systems, with or without storage, for self-consumption of the electricity used in their agricultural activity, reducing their energy costs. It runs alongside the Solar Rooftops programme and is delivered through the state gov.gr service channel, with siting restrictions on high-productivity farmland.
Who it is for: Professional and other registered farmers listed in the Register of Farmers and Agricultural Holdings running an eligible agricultural business.
Virtual net billing / collective self-consumption
Administered by: ΔΕΔΔΗΕ and ΔΑΠΕΕΠ under ΥΠΕΝ rules
A framework that lets self-consumers benefit from a PV system located away from the point of consumption, or share one installation across several supply points in the same network area, including apartment buildings and energy communities. The self-producer declares to HEDNO which consumption supplies are included in the shared arrangement; recent legislation moved this from a virtual net metering to a virtual net billing basis, aligning shared systems with the market-price settlement used for individual net billing.
Who it is for: Energy communities, occupants of the same building and other groups of consumers within the same network area who jointly invest in or share a self-consumption system.
Before you rely on any figure — check the official source
Solar incentive rates, tariff levels, budgets, eligibility thresholds and deadlines in Greece 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 Greece → on Solar Directory.

Frequently Asked Questions
Can I still sign up for net metering in Greece?
expand_more
For most new PV connections, no. Since the 2024 reforms, net metering has been replaced by net billing as the default self-consumption scheme, and net metering now remains open only to defined groups such as municipalities and households certified as being in energy poverty. Confirm your eligibility with ΔΕΔΔΗΕ (HEDNO) and your electricity supplier before applying.
What is the difference between net metering and net billing?
expand_more
Net metering offsets the electricity your system produces against the electricity you consume over a settlement period, on an energy-for-energy basis. Net billing offsets your own consumption in real time and pays you for any surplus you export to the grid at the wholesale market price under a long-term contract, with settlement handled through your supplier and ΔΑΠΕΕΠ. Check the official sources for the exact rules that apply to your case.
Who do I apply to for a rooftop solar system and the Solar Rooftops grant?
expand_more
You apply to ΔΕΔΔΗΕ (HEDNO), the distribution operator, for a Connection Offer and then sign a Connection Agreement before the system is energised, while your electricity supplier and ΔΑΠΕΕΠ handle billing and settlement. To receive the Φωτοβολταϊκά στη Στέγη (Solar Rooftops) grant you separately submit an application on the programme's official online platform, which must already show a signed HEDNO connection agreement.
