What Sunology does

Sunology is a French residential solar energy company founded in 2021 and headquartered in Nantes, with R&D in Nantes, assembly in Rennes and Redon, and a direct-to-consumer e-commerce operation selling pre-assembled plug-and-play solar stations and batteries to French and Belgian households. Its product portfolio centers on three solar station lines — PLAY (480W bifacial HIBC panel, sold in 100,000+ units), PLAY Max (460W TopCon bifacial with an integrated 700Wh VAULT battery), and GO (a 270W entry-level kit) — complemented by a modular LiFePO4 battery family (STOREY with stackable extensions, and the portable IP65-rated VAULT) and a proprietary Home Energy Management System platform called STREAM. STREAM connects stations, batteries, and the Linky smart meter via STREAM Connect/Link/Meter accessories and embeds the SUNCAST 48-hour solar-forecasting algorithm, claimed at 95% accuracy, to automate battery charge/discharge optimization.

The business operates three monetisation layers. First, transactional hardware sales of stations and batteries through sunology.eu at prices ranging from €300 (GO) to €1,390 (STOREY Master), with interest-free installments via Alma and longer-term credit via Younited. Second, the HOME service, which provides end-to-end rooftop solar installation by 80+ RGE-certified regional technicians, offered as a one-time project or a €15.50/month subscription with €0 upfront and a 25-year guarantee; Sunology claims over 110,000 HOME installations and the position of 5th-largest residential solar installer in Europe. Third, an ecosystem layer including a 300-companion independent VDI sales network (Suno&Co at 7% commission), a referral loyalty program (S-Club, 130,000+ households, with Sunopoints rewards), financing partnerships, and grid-sale partnerships with Enedis and EDF OA for 20-year fixed-price contracts. A newer HOME Pro line extends the same offering to commercial and industrial customers.

The company is privately held, raised €10M in 2023 from RGreen Invest (a French energy-transition investment manager with €2.2B AUM, now its reference shareholder), and operates with a lean 11–50 direct-employee headcount supplemented by 80+ RGE-certified technicians and 300 VDI companions. Recognitions include Red Dot Best of the Best 2026 (PLAY Max and STOREY) and iF Award 2025, alongside independent endorsements from Que Choisir and 60 Millions de consommateurs, and 4.7/5 Trustpilot across 3,000+ reviews.

Revenue model

1. Hardware Sales (Plug-and-Play Stations): Direct-to-consumer sale of pre-assembled solar stations (PLAY, PLAY Max, GO) and battery products (STOREY, VAULT) through sunology.eu. One-time purchase model with optional financing (4x, 12x interest-free via Alma; up to 48-month installments via Younited). Prices range from €300 (GO) to €1,390 (STOREY Master). Revenue is transactional, non-recurring per unit.
2. Rooftop Solar Installation Services (HOME): Full-service rooftop solar installation for homeowners: Sunology handles design, installation by RGE-certified technicians, administrative procedures, and grid connection. Pricing is proposal-based (quote-driven). Subscription model also offered from €15.50/month for zero-upfront installation with ongoing service. Revenue is a mix of one-time project fees and recurring subscription.
3. Subscription / Leasing Model (HOME): Sunology HOME offers a solar subscription: €0 upfront, monthly fee starting at €15.50, covering equipment, installation, maintenance, and guarantee for 25 years. Customers pay for electricity produced at a rate up to 48% below their current tariff. Revenue is recurring (monthly/annual over the contract term).
4. VDI Partner Commission: Sunology compensates independent VDI companions (Suno&Co network) with 7% commission on HT sales revenue and €300 per newly recruited companion. Sunology remains the merchant and product owner; companions act as independent intermediaries. Revenue to Sunology is the full transaction value minus commissions.
5. Referral Revenue (S-Club): Existing customers earn 3% of referred customers' purchase value in Sunopoints (loyalty currency). This drives repeat purchases and referrals, contributing to customer lifetime value and revenue retention.

Partnerships

Five partnerships are on record, tiered core and supporting.

• EDF OA (Obligation d'Achat)coreOthersSunology helps customers sign the Convention d'Autoconsommation (CACSI) with Enedis and connects them to EDF OA for selling surplus solar production or full production under a 20-year fixed-price contract. This partnership enables customers to monetize excess solar energy.
• EnediscoreOthersEnedis is the French electricity distribution network operator. Sunology customers require Enedis sign-off on the Convention d'Autoconsommation (CACSI) to legally connect solar installations to the grid. Sunology handles this administrative process on behalf of customers. Enedis also provides the Linky smart meter data that powers the STREAM Link device.
• Alma (Payment Provider)supportingOthersAlma provides interest-free installment payments (4x and 12x) for Sunology customers in France and Belgium. Available for orders over €100, up to €3,000. Alma is a regulated payment solution that enables customers to spread purchase costs.
• Younited (Credit Provider)supportingOthersYounited provides installment credit financing (12x interest-free or 24/36/48 monthly payments) for orders from €100 to €50,000. Younited Pay is a regulated credit product, subject to creditworthiness assessment.
• ConsuelsupportingOthersConsuel is the French electrical safety certification body. Traditional solar kit installers require Consuel certification (~€190 cost). Sunology's pre-assembled and factory-tested stations (PLAY, GO, PLAY Max) carry a full CE certification for the entire system, eliminating the need for individual Consuel certification — a key competitive differentiator.

Scale indicators11 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• Enphase Energy: US-listed microinverter manufacturer whose IQ8 micro-inverters underpin Sunology's plug-and-play stations; competing vertically-integrated player (Enphase's own IQ batteries + Light HVAC) addresses the same residential solar + storage stack.
• Engie Home Services: French incumbent utility's residential solar and HVAC installation arm; competes with Sunology HOME on rooftop solar plus adjacent home-energy renovation products.
• TotalEnergies (incl. SunPower): Multi-energy incumbent now owning SunPower's residential solar franchise; covers both residential rooftop and broader energy services, making it a portfolio competitor rather than a niche rival to Sunology.
• EDF Solutions Solaires (EDF ENR): The incumbent French utility's residential solar installation arm, leveraging EDF's brand and grid relationship (EDF OA) — overlapping channel but vastly larger scale and legacy access to French households.
• SolarEdge: Global inverter and now-optimiser + battery supplier to residential solar; comparable product portfolio (PV inverter, battery, EV charger, HEMS) competing with Sunology's STREAM/Panels/Battery bundle.
• SunPower: US-originated residential solar brand (now TotalEnergies-owned) with strong rooftop + storage + installer-network model; relevant as a transatlantic comparable in scale, channel and product breadth.

Regional players

• GreenYellow: French energy-services company (Casino Group) active in commercial and residential solar self-consumption; overlapping SMB rooftop market with Sunology HOME Pro.

Direct peers

• Hellio: French residential energy services platform covering rooftop solar, heat pumps and energy renovation with national installer network and subsidies administration; competes with Sunology HOME for rooftop contracts.
• MyLight150: French residential solar startup headquartered in Lyon, offering plug-and-play kits plus battery storage and local production — directly comparable product and market to Sunology PLAY/PLAY Max and STOREY.
• Beem: French plug-and-play residential solar startup offering consumer solar kits with companion app; the closest direct French competitor to Sunology's PLAY/PLAY Max product line and D2C GTM.
