Roof Mounted

The use case for our Roof-Mounted VAWT

Our roof-mounted Vertical Axis Wind Turbines (VAWTs) offer a practical solution for urban and commercial renewable energy generation. Designed to capture wind from any direction, they are particularly well suited to the complex and turbulent airflow commonly found around buildings.
Their compact footprint, low rotational speed and low-noise operation are intended to support integration with suitable rooftop structures, subject to site-specific assessment. By generating clean energy on-site, Flag Turbines can reduce reliance on grid electricity, lower operational carbon emissions and contribute to building energy-efficiency targets.
Used alongside solar and battery storage where appropriate, roof-mounted Flag Turbines can form part of a balanced, year-round renewable energy system for modern low-carbon buildings.

Benefits of our Roof Model

Space Efficiency

Flag Turbines are more compact and lower profile than traditional horizontal axis wind turbines (HAWTs), making this product well-suited for rooftop installations where space is limited.

Lower Wind Speeds

Our Roof Mounted turbines can operate efficiently at lower wind speeds, which is beneficial in urban environments where wind conditions may not be as strong or consistent as in open areas.

Quiet Operation

Wind turbines are often associated with noise, but we have taken extra measures to ensure that our products are quiet and suitable for urban areas where noise pollution is a concern.

Start Small, Grow Big

Flag Turbines Products can be easily scaled for different power needs, from small residential installations to larger setups for commercial buildings, providing flexibility in energy generation.

Low Structural Load

Our Flag Turbines Roof Mounted Product operates at low stress on the mounting structure making them better suited for mounting on rooftops without requiring extensive reinforcement.

Built for Urban Sites

Our roof-mounted solution is effective in urban environments because it can function in turbulent and omnidirectional wind conditions, which are common in cities due to the close proximity of buildings.

Low Vibration

Low vibration means quieter operation, so our turbines suit urban and residential areas where noise is a concern. It also reduces wear on components and limits structural load, making rooftops and other sensitive sites viable.

Bird & Bat Friendly

Bird and bat safety is built into the design. The blades turn slowly, at 20 to 30 rpm, and are four to five times larger than a conventional turbine’s, so they are easy to see. They move horizontally across the line of sight, not vertically through flight paths.

All-Direction Wind Capture

Wind can come from any direction but our Roof Mounted turbine operates without the need to be continuously reoriented, which is a significant advantage in areas with variable wind directions, common in urban settings.

Low Visual Impact

Flag Turbines Roof Mounted Design has a lower profile and less visually obtrusive design, which is important for maintaining the aesthetic appeal of any building or residential area.

Easy Access, Easy Maintenance

All components are closer to the ground or roof surface, making maintenance easier and safer.

Sustainable

Our turbines avoid rare-earth magnets and large, solid composite blades. Their modular construction allows parts to be repaired or replaced rather than the whole turbine, and they are designed to be recyclable at end of life.
