Rooftop and site-mounted generation for industrial and commercial premises

A single vertical wind turbine on a commercial rooftop or industrial site generates clean power directly at the point of use — reducing grid dependence and cutting electricity costs.

  • 50 kW or 100 kW turbine options
  • Suitable for rooftops, yards, and constrained sites
  • Low noise, no vibration
  • Paired with battery storage for 24/7 availability
  • Delivery approximately 3 months
Distributed portfolios

Infrastructure-grade income streams from distributed wind portfolios

At larger scale, distributed vertical wind portfolios across multiple sites create infrastructure-grade income streams — with carbon credit revenue, grid services participation, and long-term contracted returns.

  • Multi-site portfolio structures
  • Carbon credit revenue stacking
  • Grid services participation
  • Investor-grade contracted returns
  • Suitable for owners with multiple assets

Why vertical axis

Built for sites conventional turbines cannot serve

Advantages

Lower wind speed threshold

Vertical axis turbines generate power at wind speeds where conventional turbines cannot operate — extending viable generation to more sites.

Omnidirectional

No yaw mechanism required. Vertical turbines capture wind from any direction simultaneously — critical for urban environments with variable airflow.

Silent operation

No blade-tip noise. No vibration transmission. Rooftop and urban installation is viable where conventional turbines would create unacceptable disturbance.

Result

+3% / £24k

An apartment building increased asset value by 3% and added £24,000 in annual income from rooftop wind and solar installation.
