Series A

Turning agriculture’s largest energy users into electrified, flexible power plants

High-tech greenhouses hold 32 GWp of electrification potential, on roofs that are already built and already connected to the grid. Voltiris turns that roof into power while improving the crop.

Why now

Growers are leaving gas. The grid cannot follow.

Gas power plant

Growers are leaving gas

Gas prices reached up to 10× pre-2022 levels at peak. Carbon costs rise and Dutch greenhouses must be climate-neutral by 2040. Heat pumps, e-boilers and batteries top growers’ investment plans.

High-voltage lines

Grids are saturated

Electrified heat multiplies power demand. In key horticulture hubs, growers wait up to 10 years for a bigger grid connection, and peak tariffs penalise unmanaged loads.

Inside a Voltiris-equipped greenhouse

The roof is the answer

The greenhouse roof is the largest surface on site, already built and grid-connected. Voltiris is the only solution that turns it into power while improving the crop.

Voltiris spectral module
The solution

Plants use 45% of sunlight. We turn the other 55% into electricity.

Spectral modules under the greenhouse roof let through the light the crop needs and convert the rest. Less heat stress for the plants, power for the site, no extra land.

Validated, adopted, and in demand

Meier Gemüse greenhouse equipped with Voltiris modules
Meier Gemüse, Switzerland. One hectare of tomatoes, the first industrial-scale installation. A second hectare is live in the Netherlands.

“With Voltiris, we produce more energy on site, which cuts our costs and our dependence on the grid.”

Jérémy Blondin · Domaine des Mattines, Switzerland

“What really convinced me was the drop in temperature inside the greenhouse.”

Philippe Magnin · Champs du Loup, Switzerland

“Everything went smoothly from A to Z, exactly as we had discussed and agreed.”

Ruedi Meier · Meier Gemüse, Switzerland

Business model

Each hectare brings CHF 1.1M up front and 25 years of recurring revenue

Two ways to sign
  • Direct sale. The grower buys the assets, ~5 years payback.
  • Energy-as-a-Service. No upfront investment for the grower, power at a fixed cost for the life of the installation.
Capital-light by design
  • Infrastructure funds own the solar and battery assets under 25-year EaaS contracts, not our equity.
  • Modules are built by partners to our design, with 3M as industrial partner. Equity funds the platform and the grower relationship.
