Frequently Asked Questions
- Can the photovoltaic invoice be signed electronically?
- The Consumer Code allows electronic signature for quotes (Art. L.221-13). eIDAS (AES) has the presumption of reliability of Article 1367 of the Civil Code necessary to prove the EXACT date of signature.
- What's the withdrawal period after signing?
- 14 calendar days from the date of signature of the quote (Consumer Code L.221-18), for quotes signed at a distance or at home, unless the customer expressly requests advance execution (rare in PV as the customer loses the right of withdrawal).
- What VAT should I apply to a PV quote?
- VAT 10% for PV installations of ≤ 3 kWc in the main residence > 2 years (reduced rate, Article 279-0a CGI). VAT 20% for installations of > 3 kWc, new installations, tertiary buildings and total sales.
- What are the mandatory terms on a PV quote?
- Installer identity (SIRET, QualiPV RGE), customer, site address, detailed description (make/models of modules + inverter), kWc power, unit price HT and TTC, VAT, overall price, payment conditions, guarantees (ten yearly 10 years, two yearly 2 years, performance often 20-25 years), time of performance, GTC, mention of the right of withdrawal 14 days.
- Is the quote enforceable once signed?
- Yes the quote signed by both parties becomes a firm contract (Article 1101 of the Civil Code). Subsequent amendments = written endorsement signed by both parties. The eIDAS electronic signature provides the same opposing effect as a paper quote (Article 1366 of the Civil Code).
- How long is a PV quote valid?
- The cost of the electricity supply is calculated by dividing the cost of the electricity supply by the cost of the electricity supply.
- Does the PV quote have to mention the EDF OA tariff?
- Yes for installations sold in full or in surplus, the quote must mention the EDF OA purchase price applicable on the planned date of commissioning (Tariff Order S2 2026 or later).
- What happens if there is a dispute over the quote?
- Firstly, mediation through the consumer mediator of the branch (FFB for the BTP). Otherwise, legal action before the court of the place of performance of the contract.
