What Sunzil does

Sunzil is a French photovoltaic (PV) engineering, procurement, construction, and operations company that designs, installs, and maintains solar energy systems for residential homeowners, professionals (businesses, farmers, commercial/industrial operators), local authorities, and large enterprises across the seven French overseas territories: Guadeloupe, Martinique, Guyane, Réunion, Nouvelle-Calédonie, Polynésie, and Mayotte. Founded approximately 40 years ago (circa 1984) and headquartered in Dardilly, France, the company operates through four regional subsidiaries (Sunzil Caraïbes, Martinique, Océan Indien, Nouvelle-Calédonie) with local sales, engineering, installation, and O&M teams. Its core technology stack covers grid-connected and off-grid PV systems with or without battery storage, plus specialized anti-cyclonic installation design tailored to tropical island environments. The company is jointly owned by EDF and TotalEnergies, which provides shareholder stability and underwrites long-term module performance guarantees (30-year, ≥80% rated power retention).

Sunzil monetizes through a diversified mix of revenue streams: (1) turnkey installation sales with multi-stage payment terms (one-time project revenue); (2) long-term electricity sale contracts where professional customers sell surplus generation to EDF SEI at regulated tariffs of 14–29 c€/kWh under 20-year fixed-price agreements; (3) roof/land rental arrangements where Sunzil finances, builds, and operates solar plants on third-party property for 20–30 years, paying annual rent; (4) recurring O&M services for both owned and third-party PV plants, with a dedicated control room in Réunion; and (5) fee-for-service technical audits via the proprietary PVlab mobile diagnostic laboratory (thermography, flash testing, electroluminescence). Notable reference projects include Boulouparis (11.2 MWc, 16.6 GWh/year), Mahana O'Hiupe in Polynésie (10.7 MWc + 13.8 MWh storage, the largest in French Polynesia), and a 1.28 MWc installation on the Carrefour Punaauia retail rooftop. The company holds AQPV, ISO 9001, ISO 14001, and RGE certifications, all required or expected for eligibility under French overseas territory regulated tariff frameworks.

Revenue model

1. Solar Installation Sales (Clés en main): Turnkey sale of photovoltaic installations (panels, inverters, batteries, mounting structures) to residential and professional customers. Revenue is generated from the upfront sale of equipment and installation services. Payment terms include a minimum 10% deposit at order signing, 60% at suspensive condition clearance, and balance upon work completion. Installations are sold with various configurations: grid-connected self-consumption with or without storage, or full grid injection. The installation includes administrative handling (permits, grid connection, subsidies).
2. Electricity Sales (Vente d'électricité): Professional customers install PV generators on their buildings and sell the produced electricity to EDF (via regulated tariffs) under 20-year fixed-price contracts. Revenue per kWh ranges from 14 to 29c€ depending on territory and installation size (per the January 2024 tariff order). The tariff is revised quarterly. EDF commits to purchase electricity at fixed rates for 20 years, providing secure, long-term revenue for professional customers and driving demand for Sunzil installations.
3. Roof/Land Rental: Sunzil installs and operates solar plants on customer-owned rooftops or land (minimum 250m²) for 20–30 years. The property owner receives a regular annual rent in exchange for allowing use of the surface. Sunzil handles construction, maintenance, and grid connection. This is marketed to industrial building owners, agricultural operators, and local authorities.
4. Operations & Maintenance (O&M): Sunzil provides ongoing maintenance and exploitation services for solar installations, both for its own portfolio and for third-party owners. Services include preventive and corrective maintenance, performance monitoring, and operational management. A control room in Réunion specializes in monitoring PV plant performance.
5. Technical Audit Services: Fee-for-service technical audits of existing PV installations. Includes mobile laboratory diagnostics (thermography, flash testing, electroluminescence), fault analysis, performance optimization recommendations, and dispute resolution support. Targeted at PV plant operators seeking to diagnose underperformance or validate plant condition.
