Developing a revolutionary solution for agricultural greenhouses, Swiss startup Voltiris has developed a technology that makes it possible to use solar energy for both plant growth and electricity generation. The new system separates sunlight through spectral filters, directing the wavelengths needed by plants into the greenhouse and converting the remaining light into electricity. This way, plants have enough energy to grow and greenhouses can produce 150 watts of energy per square meter.
This technology solves one of the biggest problems in greenhouses: lack of light and high energy costs. While normal solar panels reduce the light in greenhouses by 70%, this new system optimizes the light intensity for the benefit of the plants. It also reduces the number of pests by 70%, providing a healthier production environment and reducing water consumption.
The system can meet the heating needs of greenhouses in winter, while excess energy is sold to the grid, generating additional income for farmers. This innovative solution, which is available across Europe, also provides farmers with easy financing through electricity sales agreements. For example, farmers can use the system with a commitment to purchase electricity without paying installation costs.
Supporting carbon neutrality targets in greenhouse agriculture, this technology is shaping the future of sustainable agriculture, providing both economic and environmental benefits.
