What gruun does

Gruun is a Dutch sustainable energy installation company headquartered in Tilburg, Netherlands, that designs, installs, and services residential and light-commercial energy systems including solar panels, solar roofs, solar carports, heat pumps, home batteries, and EV chargers. The company operates a small, specialized technical team and runs an in-house test field used to validate product configurations prior to deployment, an asset uncommon for a regional installer. Service delivery is project-based across multiple customer segments, with InstallQ certifications supporting recognized installer status in the Dutch market.

The company's technology stack combines hardware installation with a software layer in its home battery offering that uses AI-driven optimization against EPEX wholesale electricity prices to automate charge/discharge timing. Gruun supplements internal capabilities through partnerships with specialized providers such as Robisol (solar roofs) and Opdenduurzaam (heat pumps), and is part of the Turific Duurzaam group, which provides broader operational and platform support.

Gruun's business model is project-based installation revenue from sales, deployment, and after-sales service contracts across a diversified product mix. Go-to-market is centered on direct sales supported by partner referrals and project showcases, serving residential and SME customers across the Netherlands rather than a single anchor segment. Revenue mechanics are tied to project volume and ticket size across multiple verticals rather than recurring SaaS or subscription streams.
