Warsaw/Monaco, 9 September 2025

Carlson Investments SE proudly presents its portfolio company OnReVolt, a Polish innovator developing renewable energy technologies that bring energy independence closer to households across Europe. By integrating wind, solar, and storage solutions, OnReVolt helps reduce CO₂ emissions, cut costs, and provide communities with clean and reliable energy.

A highlight of OnReVolt’s work is its domestic wind turbine, specifically designed for Europe’s low-wind climate. The system features transparent blades made from recycled PET bottles, enabling generation at wind speeds as low as 1 m/s and complementing photovoltaic installations when solar output is low. The compact, modular system weighs just 60 kg, requires no permits (due to its 3.5 m installation height), and operates quietly at 40 dB, making it an ideal fit for residential areas.

Key Features of the OnReVolt Wind System

• Energy production starting from wind speeds as low as 1 m/s

• Transparent, lightweight blades made from recycled PET bottles

• Complements solar panels, especially in autumn and winter

• Modular design (60 kg) with permit-free installation

• Quiet operation at 40 dB

• Real-time monitoring and yield guarantees based on live and historical data

Beyond wind, OnReVolt is developing a holistic home energy model that integrates heliostat-boosted solar panels, heat pumps, and high-efficiency LiFePo₄ storage systems. This approach maximizes self-consumption of renewable energy and offers households flexible financing: a 10-year contract with monthly bills 20% lower than current rates, or an OZE loan with subsidies reducing costs during the payback period.

With EU co-financing of EUR 200,000 and a recent funding round of EUR 814,000 (January 2025), OnReVolt is preparing around 12 pilot installations across Europe. The company is committed to transparency and publishes real-world performance data to validate its technology and demonstrate how households can take control of their energy future.
