The infusion of capital will support product validation and the deployment of VajaTrack, a vertical single-axis tracking system. Unlike horizontal trackers that revolutionized solar economics near the equator, Vaja’s technology targets the other half of the planet. By adjusting to capture light during morning and evening hours, the system promises 25-50% higher revenue compared to traditional fixed-mount installations in Europe, North America, and Asia.
Stockholm-based Vaja secures €3.1 million to scale vertical solar tracking
Stockholm startup Vaja AB has closed a €3.1 million seed round led by The Footprint Firm, pushing its total capital to €6 million. The company is betting that its vertical tracking system, designed to capture higher yields at northern latitudes, will replicate the global dominance of horizontal solar trackers.
CEO Henrik Eskilsson, who co-founded the firm alongside Anders Olsson, views this technology as essential for northern energy independence. As European markets prioritize domestic generation, the ability to increase efficiency beyond 30° latitude provides a clear competitive edge. Jakob Wichmann of The Footprint Firm highlighted that the team’s background in structural engineering was a deciding factor for their investment. With production slots for 2026 already filling up, the company is now prioritizing pilot projects with agricultural partners and professional solar developers.
