|---|---|
| Tower options | Project-specific lattice or cylindrical tower |
| Reference option | 11 m S235JR lattice tower |
| Reference mass | Approx. 245 kg |
| Anchoring | M24 anchor system |
| Foundation | Preliminary 1.5 x 1.5 x 1.5 m; structural verification required |
| Site assessment | Wind potential, turbulence, tower height and soil conditions must be determined through project-specific structural and geotechnical calculations |
| Engineering note | Local structural approval required |
| Tower heights | 12 – 24 m, chosen per site analysis |
Site selection principles
- Obstacle assessment — map buildings, trees and terrain that disturb wind flow.
- Correct tower height — keep the rotor above turbulent airflow.
- Prevailing wind direction — align placement with the dominant wind.
- Ground conditions — choose stable ground for lasting foundations.
- Optimal placement — prefer open areas with uninterrupted wind.
Installation process
- Site survey
Wind potential, turbulence, obstacles, tower height and soil are assessed. - Foundation
Excavation, anchors and concrete are executed as one engineered base. - Tower
The tower is lifted, aligned and secured by professional installation teams with controlled on-site assembly. - Turbine
Generator, rotor and electrical connections are installed, verified and prepared for commissioning. - Electrical integration
Controller, battery, dump load and inverter are connected. - Commissioning
The system is tested and handed over for energy production.
