What Voltiris does

Voltiris is a Swiss agrivoltaics company that has developed a patented spectral filtering photovoltaic module designed to be installed inside greenhouses without reducing crop yield. The core technology, co-developed with 3M, uses dichroic filters to selectively redirect wavelengths (red and blue light) that are least useful for photosynthesis onto bifacial solar cells, while transmitting the full photosynthetically active radiation (PAR) spectrum needed for crop growth. The system includes dual-axis tracking, claimed to extend daily energy production by up to 35% versus static PV, and reduces peak plant temperature by up to 7-10°C. Voltiris targets large-scale commercial greenhouse operators growing tomatoes, cucumbers, peppers, strawberries, and ornamentals, and secondary channel partners including energy utilities and cooperatives (EBL Elektra Baselland, Romande Energie).

The company's revenue model combines one-time hardware sales with an Energy-as-a-Service offering launched in 2025, under which Voltiris retains ownership of the installed modules, handles maintenance and upgrades, and bills the grower only for the electricity generated — eliminating upfront capital expenditure. Customers can reportedly reduce energy costs by up to 30% and cover up to 70% of their energy needs. Voltiris's go-to-market is sales-led via direct enterprise field teams, complemented by channel partnerships with regional energy utilities and installers (e.g., Genson Group in the Netherlands) and validation partnerships with leading agronomic research institutes (University of Wageningen, Delphy, Proefcentrum Hoogstraten).

Voltiris SA is incorporated in Epalinges, Switzerland, with a wholly-owned Netherlands subsidiary (Voltiris Netherlands) for Benelux operations. The company has raised a CHF 4.8M seed round (January 2025) co-led by 3M Ventures and EquityPitcher Ventures, plus a CHF 3M facility from the Swiss Technology Fund (June 2026), alongside earlier pre-seed, grant, and debt tranches. Notable deployments include the world's first hectare-scale spectral filtering installation at Meier Gemüse in Rütihof, Switzerland (~2,000 modules producing ~1 MWh/day), with international expansion underway into France, Belgium, the Netherlands, and China via a strategic partnership with AIKO Energy.

Core offering

Voltiris designs, manufactures and operates spectral filtering photovoltaic modules installed inside greenhouses. The patented dichroic filter (co-developed with 3M) transmits the full light spectrum required for photosynthesis while redirecting non-essential wavelengths to bifacial solar cells, enabling commercial greenhouse operators to generate on-site renewable electricity without reducing crop yield. The company delivers these modules either as capital hardware or through an Energy-as-a-Service (EaaS) subscription in which it retains ownership and bills growers for the energy produced.

Product overview

Voltiris offers a unified spectral filtering solar module system designed specifically for greenhouse agriculture. The core product is the Voltiris spectral filtering PV module, which uses patented dichroic filter technology co-developed with 3M to transmit essential light wavelengths for photosynthesis while redirecting unused spectrum to solar cells for electricity generation. The system includes dual-axis tracking for optimal energy production. Voltiris packages this technology through an Energy-as-a-Service model that eliminates upfront capital costs for growers, handling installation, maintenance, and upgrades while customers pay for electricity generated. The solution is designed for installation inside greenhouses without requiring permits, and is compatible with light-loving crops including tomatoes, cucumbers, peppers, strawberries, and ornamental plants.

Others

• AIKO Energy: China's leading clean energy company and Voltiris's strategic partner for Asian market expansion. Adjacent in PV manufacturing and distribution; relevant as both a partner and potential competitor in the Chinese greenhouse market.

Direct peers

• Insolight: Swiss-based developer of semi-transparent PV modules designed for greenhouses and building-integrated applications. Closest direct competitor to Voltiris in the spectral-selective greenhouse solar category, with comparable EPFL-adjacent technology roots.
• Brite Solar: Greece-based company developing semi-transparent perovskite-on-glass solar modules for greenhouses. Competes with Voltiris for greenhouse agrivoltaics projects across Europe with a different (transparent coating) technical approach.
• Sun'Agri: French agrivoltaics pioneer operating dynamic solar systems for orchards, vineyards, and field crops. Adjacent competitor in the European agrivoltaics market, with more deployment experience but less specialization in greenhouse-only applications.
• Ombrea: French agrivoltaics company (subsidiary of TotalEnergies) developing smart solar canopies for crop protection and energy generation. Comparable business model (climate + energy) but primarily focused on open-field crops rather than greenhouses.
• ClearVue Technologies: Australia-based company producing spectrally-selective solar glazing for greenhouses and building facades. Closely comparable spectral-splitting technology approach, though targeting different geographies and crop types.

Emerging players

• UbiQD: US-based quantum dot company developing luminescent greenhouse films that convert sunlight to crop-optimized spectra. Adjacent technology approach to spectral management for greenhouse productivity.
• Next2Sun: German company specializing in vertical bifacial agrivoltaics systems. Adjacent competitor in the dual-use solar-and-agriculture category, though focused on open-field rather than greenhouse applications.

Broad incumbents

• BayWa r.e. Large German renewable energy developer with an established agrivoltaics business unit serving European growers. Competes with Voltiris for greenhouse projects at scale, though as a broad renewables player rather than greenhouse specialist.
• TotalEnergies (agrivoltaics): Global energy major with growing agrivoltaics investments in Europe through Ombrea and direct projects. Represents the threat of large incumbent energy companies entering greenhouse solar at scale.
