Holdigaz SA

What Holdigaz SA does

Holdigaz SA is the holding entity at the apex of Holdinova, a Swiss group of 19 energy and building-services companies operating across French-speaking Switzerland (Suisse romande). Its primary operating subsidiary, Agena SA, is a solar energy specialist founded in 1980 and headquartered in Forel (Lavaux), Canton Vaud, with a stated team of 45 employees. The group's gas distribution operations, conducted through Compagnie industrielle et commerciale du Gaz, Société du Gaz de la Plaine du Rhône, and Cosvegaz, serve 153 communes across Vaud, Valais, and Fribourg, providing a broad regional distribution backbone.

Agena's product set spans photovoltaic (PV) solar systems, solar thermal collectors, geothermal and aerothermal heat pumps, battery storage from brands including Sonnen, SolarEdge, and Huawei, and electric vehicle charging stations. Installations are executed on roofs, facades, canopies, and ground-mounted configurations for residential, commercial, industrial, agricultural, and public buildings, using inverter and module brands such as SolarEdge, Huawei, Kostal, BISOL BIPV, AXITec, and Aiko. The company also acts as qualified installer under a solar contracting model operated jointly with group affiliate Energiapro, allowing large rooftop owners to access renewable electricity without upfront capital outlay, and has installed roughly 5,500 m² of PV across its own group's rooftops at Lavigny, Forel, and Vevey.

The business model is predominantly turnkey, project-based installation revenue billed per project, supplemented by a recurring managed-services component through the Energiapro contracting partnership. Go-to-market combines enterprise field sales with event-driven demand generation at regional trade shows (Les Journées fribourgeoises du photovoltaïque, Energissima) and direct contact-form lead capture, while distribution is entirely direct with no reseller channel. Customer segments range from individual and collective housing to artisanal, industrial, public, healthcare, education, railway, and cultural clients, with named references including Ecorecyclage SA, SBB/CFF, Collège Gustave Roud, Grand Chétuan, Cully360, and Théâtre le Reflet.

Core offering

Holdigaz SA (via its Agena SA subsidiary) delivers turnkey solar photovoltaic and thermal installations, heat pump systems, battery storage, and EV charging stations for residential, commercial, industrial, agricultural, and public buildings across French-speaking Switzerland. Services span needs analysis, custom design, performance simulation, permits, subsidies management, and complete project realization by employed technicians. A solar contracting offering, delivered in partnership with Energiapro, allows large rooftop owners to access renewable electricity without upfront capital investment.

Product overview

Agena is a solar energy company within the Holdinova group, active since 1980, operating across French-speaking Switzerland. The company's offering is organized around five core products — photovoltaic solar (Solaire photovoltaïque), thermal solar (Solaire thermique), heat pumps (Pompe à chaleur), battery storage (Batterie de stockage), and EV charging stations (Borne de recharge) — supplemented by mounting systems, solar contracting services, and turnkey project management. Photovoltaic and thermal solar form the primary product lines, with heat pumps and battery storage offered as complementary technologies that increase self-consumption of solar power. The company also acts as a qualified installer for solar contracting (through the Energiapro partnership) and provides full project management from needs analysis and sizing through to permits, installation, and commissioning. The product portfolio covers residential (individual villas, apartment buildings), commercial, agricultural, industrial, and public building segments, with installations performed on roofs, facades, canopies, ground-mounted systems, and solar tiles.

Products and services

• Photovoltaic Solar (Solaire photovoltaïque) Turnkey solar photovoltaic installation service converting sunlight into electricity, using solar modules (BISOL BIPV, AXITec, Aiko) and intelligent inverters (SolarEdge, Huawei, Kostal). Offered for residential, commercial, industrial, agricultural, and public buildings, with installations on roofs, facades, canopies, or ground-mounted systems.
• Thermal Solar (Solaire thermique) Solar thermal installation using collectors to capture heat from solar radiation, combined with a boiler for domestic hot water (ECS) production and partial space heating. Includes thermal collectors and hydraulic systems for hygienic hot water production without legionella risk.
• Heat Pump (Pompe à chaleur) Heat pump systems using heat from the ground (geothermal) or air (aerothermal) to heat and cool buildings and produce domestic hot water. Includes air/water and ground/water heat pump units suitable for renovation and new construction projects.
• Battery Storage (Batterie de stockage) Battery storage system storing excess solar electricity for later use, increasing self-consumption and reducing grid electricity costs by up to 80%. Simple, flexible, and modular systems from brands including Sonnen, SolarEdge, and Huawei.
• EV Charging Station (Borne de recharge) Electric vehicle charging stations offered as part of integrated solar energy solutions for residential and commercial buildings.
• Solar Contracting (Contracting solaire) Solar contracting service offered in partnership with Energiapro, enabling property owners — particularly of large rooftops, commercial buildings, production sites, and agricultural facilities — to access renewable electricity without upfront financial investment. Agena handles installation and operation while Energiapro commercializes the energy.
• Mounting Systems (Systèmes de montage) Mounting systems for solar installations adapted to various applications — integrated into roofs or surface-mounted — available for roofs, facades, and ground applications.
