Stolze

What Stolze does

Stolze Installatietechniek BV is a Netherlands-based system integrator founded in 1969 that designs, installs and services the technical infrastructure of commercial greenhouses and indoor farms. Its offering spans five core disciplines: electrical engineering, water technology, grow lighting (LED, hybrid, HPS), automation and climate technology, with proprietary elements including the Stolze Connected integrated process management platform, custom SLS Premium lighting panels, prefabricated cable harnesses and an underground water storage system using borehole filtration. Stolze integrates third-party climate computers (Priva, Hoogendoorn IIVO) and LED hardware (Signify/Philips GreenPower) into turn-key installations, supported by in-house prefabrication, regional service offices in Maasdijk, Aalsmeer and Waspik, and 24/7 fault reporting.

The company serves enterprise greenhouse operators across a diversified crop mix — tomatoes, chrysanthemums, potted roses, Phalaenopsis orchids, hydrangeas, aquatic plants, Lisianthus, young plants and cut flowers — plus research institutions and a robotics/automation customer (SAIA Agrobotics, GreenTech Robot Challenge Award winner). Customer engagements are project-based and range from targeted system upgrades to multi-hectare turn-key installations (e.g., 193,000 m² in Azerbaijan, 103,000 m² U Grand chrysanthemum greenhouse, 45-hectare Vreugdenhil-Klugt LED rollout) with quantified outcomes including 50% energy savings and 40% more light per kWh (Bryte), 100% water recycling (Pico Bello Hortensia) and 420 tons/hectare winter tomato yield in an unlit Azerbaijan climate.

Since late 2020 Stolze has been part of the GreenV group alongside Prins Group (greenhouse construction), HT Verboom (internal transport), Green Simplicity (CEA research systems), Voshol and JV Energy Solutions, with HAL Investments as long-term capital partner. Stolze has executed two tuck-in acquisitions (Elektravon Tuinbouw in April 2024 and the horticultural technology department of Vos Capelle in February 2025) to extend domestic coverage, while international project delivery is documented in Mexico, the United States, Canada, Ethiopia and Azerbaijan. Revenue is generated through one-time installation projects, recurring maintenance and inspection contracts, and consultancy services, sold exclusively through a direct enterprise field-sales motion.
