Frequently Asked Questions

Can the EDF OA PV contract be signed electronically?
Yes, without restriction since 2019 via the EDF OA Solar portal. The Energy Code does not impose any particular form for the OA contract. The advanced eIDAS signature benefits from the presumption of reliability of Article 1367 of the Civil Code essential for a 20-year commitment.
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.

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?
