Sign a contract for the purchase of EDF OA photovoltaic in 2 minutes
The purchase contract itself is signed on EDF OA's electronic signature portal, built with Luxtrust: an email invitation, a review of the documents, confirmation by SMS code. Certyneo secures everything around it — the mandate given to the installer, the quote, the RGE QualiPV certificate, the certificate of compliance — with an eIDAS advanced signature and archiving aligned with the contract's 20 years.

What is a purchase agreement for EDF OA?
The contract for the purchase of photovoltaic electricity, commonly known as the EDF OA contract (Purchase Obligation), is the commitment by which EDF Obligation d'Achat (a subsidiary of EDF, obliged purchaser designated by the State) undertakes to purchase for 20 years all or part of the electricity produced by a photovoltaic installation, at an indexed and guaranteed price.
Why sign the EDF OA purchase contract electronically?
EDF OA signs on its own portal
EDF OA "provides an electronic signature portal developed in partnership with Luxtrust": an email invitation, a mandatory review of the documents, confirmation by a code received by SMS. So you do not upload to EDF OA a purchase contract signed elsewhere. Certyneo comes in upstream, on the deeds you sign with your installer and your co-holders.
Tripartite owner + installer + EDF OA
The OA contract involves three parties: the owner (producer), the installer RGE QualiPV (often the agent for the procedure), EDF OA (buyer).
20 years of aligned OA contract duration
The OA contract has a term of 20 years (Tariff Order).Certyneo archives the contract + audit trail eIDAS for 10 years (minimum legal term) with possible contract extension to cover the entire duration of the OA contract + 5 years after expiry.
The eIDAS audit trail is open to objection
Each OA contract is supplied with a PDF of proof: identity of the signatories (producer + EDF OA + installer), RFC 3161 timestamping, SHA-256 hash, IP geolocation, OTP SMS verification.
Signing of a four-stage purchase contract for EDF OA
From Consuel to the commissioning of EDF OA, the contract secures the line in less than 5 minutes.
1. Prepare the OA contract
Gather the file that triggers the contract: the certificate of compliance stamped by Consuel, the connection mandate, the RGE QualiPV certificate, peak power and type of sale (full, surplus, collective self-consumption), applicable tariff. It is this file, not the purchase contract, that you have signed in Certyneo.
2. Add the signatories
Producer (owner), any co-holders and the installer. EDF OA does not sign in Certyneo: its representative signs on its own portal. For collective self-consumption, add the PMO and the list of consumers. Each signatory receives a secure link by email with SMS OTP.
3. Choose the eIDAS level
Advanced signature (AES) recommended for a 20-year commitment: SMS OTP, a unique certificate per signatory, RFC 3161 timestamping, SHA-256 hash. It is admissible as evidence (Article 1367 of the Civil Code) and its evidence file demonstrates its reliability, the presumption being reserved for qualified signatures.
4. Sign, then follow EDF OA's invitation
Each signatory signs from their phone and Certyneo archives the evidence file. EDF OA then emails you an invitation to sign the purchase contract on its portal; with two co-holders, both must sign. Allow 30 days to retrieve the signed document before it moves to the producer area.
Frequently asked questions
- Can the EDF OA PV contract be signed electronically?
- Yes, but not in Certyneo: EDF OA has the purchase contract signed on its own electronic signature portal, built with Luxtrust — an email invitation, a review of the documents, confirmation by SMS code. The Energy Code imposes no particular form on the OA contract. Certyneo is for the deeds you sign with your installer and your co-holders; an advanced signature there is admissible as evidence (Article 1367 of the Civil Code), its reliability being shown by the evidence file.
- What is the purchase price of photovoltaics in 2026?
- The tariff is fixed by tariff Decree S2 2026 (second half of 2026), published quarterly by the CRE (Commission de régulation de l'énergie). For installations ≤ 100 kWc on total sale, about 10-13 c€/kWh depending on power. For sale of surplus with self-consumption, investment premium + surplus purchase tariff. Guaranteed and indexed tariff over 20 years.
- Total sales, surplus sales, collective self-consumption: what is the difference?
- Total sales = 100% of the production sold to EDF OA, injection connection only. Surplus sales = self-consumption + resale of the surplus to EDF OA, extraction and injection connection. Collective self-consumption (Decree 2017-676) = production shared between consumers within a radius of 2 km (20 km in rural areas) via a PMO.
- What is the duration of the EDF OA contract?
- 20 years since the 2017 tariff decree for the photovoltaic roof. The contract starts on the date of commissioning certified by the Consul. At the end of the contract, the possibility of extension at the market rate or switching to another buyer (aggregerator, alternative supplier).
- What documents does EDF OA require with the contract?
- Consular certificate (AC or Green Visa), qualiPV RGE certificate from the installer, proof of ownership or lease with authorization, unifilar scheme, floor plan, price and invoice paid, Enedis connection contract (CRAE).
- Is the price of photovoltaic photovoltaic products indexed?
- Yes, the purchase price is indexed to the INSEE index of industrial output prices (IPP) for the electricity production and distribution sector.
- Can the OA contract be terminated before 20 years ?
- Yes, but with restrictions: on the producer side: possible termination with 1 year's notice + penalty (proportionate to seniority); on the EDF OA side: termination only in case of serious non-compliance (fraud, persistent technical non-conformity).
- What happens when the 20 years are up?
- At the end of the contract, the OA contract expires. The producer can: (1) renew the contract at the market rate with EDF OA, (2) sign a new contract with an alternative supplier or aggregator, (3) switch to 100% self-consumption.
