Skysun

What Skysun does

Skysun is a Belgian-headquartered solar energy company that finances, installs, and maintains photovoltaic systems for commercial and industrial businesses across Belgium and France under a third-party investment model. Founded in 2017/2018 by Arthur Dawans and Léopold Coppieters, the company bears all capital and operational risk, enabling customers to receive electricity at fixed prices below grid rates without any upfront investment under multi-year contracts (10, 15, 20, or 30 years). Skysun guarantees 95% of annual announced production and compensates for shortfalls, providing contractual certainty uncommon in the solar-as-a-service space.

The company's technology portfolio spans five core installation types: rooftop photovoltaic systems (minimum 200 m²), ground-mounted solar including agrivoltaic configurations, solar carports with optional EV charging (minimum 60 parking spaces), Building-Integrated Photovoltaics (BIPV) including the patented Zinclike aesthetic solution co-developed with architectural firm Sunsoak, and Battery Energy Storage Systems (BESS) for grid stabilization. Its flagship project at Abattoirs d'Anderlecht (5,808 panels, 1.9 MWp) represents the largest BIPV installation in Europe. The standardized 'Skysun 10 Steps' methodology governs project execution from feasibility study through grid connection and regulatory filing. Additional services include roof renovation, roof rental, energy and carbon audits, VPPA off-site solutions, and grid price negotiation.

Skysun's revenue model is built on three primary streams: electricity sales/sharing with customers under long-term contracts, roof rental for grid-connected installations on low-consumption buildings, and battery storage grid-stabilization services generating passive income for property owners. The company generates revenue from surplus electricity sold back to the grid and operates across Belgium (Brussels, Genappe) and France (Paris, Strasbourg, Lyon) with a direct enterprise sales motion. As of 2024, Skysun has raised approximately €34-35 million cumulatively across a 2021 Series A and a 2024 growth round led by Andera Partners and WE International, with a stated target of €300 million in investment volume by 2030.

Revenue model

1. Electricity Sales/Sharing: Skysun installs and finances photovoltaic panels on customer properties at no cost. Revenue generated by selling electricity produced to the customer at a fixed price below grid rates, and/or selling excess electricity back to the grid. Contracts run for 10, 15, 20, or 30 years.
2. Roof Rental: For warehouses and buildings with large surfaces but low consumption, Skysun pays annual rent for use of the roof where they place a photovoltaic system whose production supplies the grid.
3. Battery Energy Storage: Revenue from providing grid stabilization services through battery installations. Property owners receive passive income for making land near high-voltage substations available for battery storage.
4. Additional Services: Energy audits, carbon audits, grid price negotiation, and roof renovation management offered as supplementary services.

Core offering

Skysun acts as a third-party investor that installs, finances, and maintains photovoltaic solar panel systems (rooftop, ground-mounted, carport, BIPV) and battery storage on commercial and industrial properties at no upfront or operating cost to the customer. The customer purchases electricity produced on-site at fixed rates below grid prices under 10–30 year contracts, with additional services such as roof rental, energy/carbon audits, VPPA, and grid price negotiation offered alongside.

Product overview

Skysun is a turnkey solar energy partner offering a comprehensive portfolio of photovoltaic solutions for businesses with no upfront investment required. The core offering consists of five main installation types: Rooftop Solar (photovoltaic panels on commercial rooftops), Ground-Mounted Solar (including agrivoltaic solutions), Solar Carports (parking lot canopies with optional EV charging), BIPV Architecture (building-integrated photovoltaics with the proprietary Zinclike system), and Battery Storage (BESS for grid stabilization and passive income). These are complemented by value-added services including roof renovation, roof rental, energy audits, carbon audits, VPPA for off-site solutions, and grid supply price negotiation. Skysun acts as a third-party investor, financing and maintaining all installations while providing electricity to clients at rates below grid prices. The company operates across Belgium and France with a standardized 10-step project methodology.

Products and services

• Solar Rooftop Installation Skysun installs and finances photovoltaic panels on commercial and industrial rooftops (minimum ~200 m²), handling structural analysis, installation, and maintenance while supplying electricity to the customer at fixed rates below grid prices with no CAPEX or OPEX.
• Ground-Mounted Solar Installation Ground-mounted solar power stations built on unused land (minimum ~1 hectare), including agrivoltaic configurations that allow grassland and crops to grow beneath elevated panels. Uses self-drilling metal screw foundations that are removable and recyclable.
• Solar Carport Solar canopies installed over commercial parking areas (minimum ~60 spaces) that protect vehicles from weather while generating electricity, with optional integration of 8 to 16 EV charging points.
• Building-Integrated Photovoltaics (BIPV) BIPV projects developed with architects to integrate solar panels directly into building design, including the proprietary Zinclike solution that combines aesthetic appeal (e.g., restoring zinc roof appearance) with photovoltaic functionality for heritage and architecturally significant buildings.
• Battery Energy Storage System (BESS) Large-scale battery installations sited near high-voltage substations that provide grid stabilization services; property owners earn passive income by making land available, while Skysun finances, installs, and operates the batteries.
• Roof Rental For warehouses and large buildings with low consumption, Skysun pays annual rent to the property owner for use of the rooftop, installs a PV system whose production is supplied to the grid, and includes comprehensive roof insurance.
• Energy Audit Consumption audit service that identifies overconsumption and supports reductions in clients' carbon footprint and energy costs.
• Carbon Audit Carbon audit service that measures, reduces, and offsets the ecological impact of client activities.
• Virtual Power Purchase Agreement (VPPA) Structures the purchase of photovoltaic energy produced locally in real-time, allowing clients to consume green energy remotely when their own buildings are unsuitable for direct installation; used to redirect surplus production (e.g., Marché International Mouscronois to Les Dauphins Olympic swimming pool).
• Grid Supply Price Negotiation Skysun's energy traders analyze and negotiate electricity supply rates and conditions with network providers on behalf of clients.
• Roof Renovation Skysun manages and finances the renovation of waterproofing membranes on client buildings, incorporated into the overall project financing structure.
