Core offering

Southern Sun (Soleil du Sud) designs, installs, and maintains photovoltaic solar energy systems across France's PACA region. The company offers rooftop solar panel installations, battery storage systems, solar parking canopies, and EV charging stations for both individual homeowners and businesses/collectivities. It operates across the full solar value chain from investment and design through to installation and operation/maintenance.

Product overview

Soleil du Sud operates as a regional photovoltaic solutions provider offering comprehensive solar energy services through two main business models: residential self-consumption solutions (with EDF surplus resale or battery storage options) and commercial/industrial third-party investment and self-consumption models. The company provides a full-service offering covering the entire solar value chain including investment, design, installation, and operation/maintenance. Key product offerings include photovoltaic panel installation, parking canopy solar structures, electric vehicle charging stations, battery storage systems, roof renovation, and asbestos removal services. The company installs VOLTEC SOLAR panels manufactured in Alsace and uses SMA inverters, primarily serving the PACA region of France.

Products and services

• Residential Solar Self-Consumption with EDF Surplus Resale Rooftop photovoltaic system for individual homeowners in PACA who consume the electricity they produce and sell surplus production back to EDF at the regulated feed-in tariff. Aims for up to 50% reduction in electricity bills.
• Residential Solar Self-Consumption with Battery Storage Rooftop photovoltaic system paired with physical battery storage for individual homeowners, enabling storage of surplus production and later consumption. Aims for up to 70% reduction in electricity bills.
• Electric Vehicle Charging Station Installation (IRVE) Residential or small-business installation of single-phase or three-phase EV charging stations, available standalone or paired with a photovoltaic system.
• Tiers Investisseur (Third-Party Investor Solar Lease) Capex-free commercial/industrial solar offering in which Soleil du Sud leases the customer's rooftop, installs and maintains a photovoltaic plant for a minimum 30-year term, and compensates the host via rent or energy-improvement works.
• Business Self-Consumption Solar (Installateur-Exploitant) Self-consumption solar installation for businesses or authorities that prefer to own and operate the plant themselves, selling any surplus production to nearby partners.
• Collective Self-Consumption — Patrimoniale Collective self-consumption offering for municipalities, social landlords, or multi-site businesses that allows them to power their own buildings with locally produced solar electricity.
• Collective Self-Consumption — Ouverte Open collective self-consumption offering that allows businesses or local authorities to extend locally produced solar electricity to nearby consumers within a 2-kilometer radius.
• Solar Panel Installation Service End-to-end solar panel deployment service covering technical and financial feasibility, personalized sizing, and installation tailored to roof type and consumption patterns.
• Solar Parking Canopy with EV Charging Turnkey installation of solar canopies over parking areas (ombrières) for shade and energy generation, paired with EV charging infrastructure including technical study, grid connection, and commissioning.
• Battery Storage Installation Installation of battery storage systems to optimize self-consumption, secure electrical supply, and maximize the efficiency of the solar installation.
• Solar After-Sales Service and Maintenance Responsive after-sales service plus preventive and corrective maintenance of solar panels to maintain performance, safety, and long-term durability of the installation.

Direct peers

• Tenergie: Tenergie is a Lyon-based French photovoltaic installer and developer offering turnkey PV solutions to B2B, public-sector, and agricultural clients across multiple regions. Directly comparable to Soleil du Sud as a French regional EPC with self-consumption, third-party investment, and storage offerings, though typically larger in scale.
• Sun'R: Sun'R is a French solar energy developer specializing in PV installations for businesses, farmers, and local authorities. Comparable to Soleil du Sud's professional/collective self-consumption and third-party investor models, with broader geographic reach across France.
• Photosol: Photosol is a major French photovoltaic developer and installer active in residential, C&I, and utility-scale segments. Comparable to Soleil du Sud's diversified PV business model but with significantly larger project portfolio and national footprint, making it an aspirational direct peer.
• Akuo Energy: Akuo Energy is a French independent renewable energy developer active in solar PV, wind, and storage with citizen-finance (Lendopolis/Enerfip) crowdfunding capability. Comparable to Soleil du Sud's Tiers Investisseur model and crowdfunding-funded project pipeline, though at substantially larger scale.
• TSE (The Solar Egg): TSE is a French specialist in photovoltaic canopies (ombrières agricoles) and agri-PV. Closely comparable to Soleil du Sud's parking canopy ('ombrières de parking') offering, both innovating in dual-use PV structures for the French market.

Broad incumbents

• EDF Renewables: EDF Renewables is the dedicated subsidiary of EDF for renewable energy development, including utility-scale solar PV, onshore wind, and storage. Acts as the dominant French incumbent across all PV segments including the EDF OA feed-in tariff framework that Soleil du Sud's customers depend on.
• Voltalia: Voltalia is a French-listed renewable energy developer with operations across solar PV, wind, biomass, and storage. Comparable as a broader French PV developer-incumbent, though at utility scale rather than the regional rooftop/C&I tier where Soleil du Sud competes.
• Engie Green (ENGIE): Engie Green is the French renewable arm of global utility ENGIE, active in onshore wind, solar PV, and biomass across France. Comparable as a broad French incumbent in renewable energy with overlapping PV EPC and O&M capabilities, but at materially larger scale.
• TotalEnergies Renewables: TotalEnergies' renewables division operates utility-scale and decentralized solar PV projects in France and globally. Comparable as a broad incumbent whose downstream C&I offerings increasingly overlap with regional installers like Soleil du Sud.
• Q ENERGY (formerly RES France): Q ENERGY is a European renewable energy developer with significant French operations across onshore wind, solar PV, and storage. Comparable as a broader incumbent active in the French C&I and utility-scale solar market alongside Soleil du Sud's regional footprint.
