5M Medium Tulip Wind Turbine

Exclusively available to installers, EPC contractors and commercial clients for medium to large scale commercial projects only. 

Lead time:  2-3 months from ordering

Minimum order quantity: 5

ITS is proud to be UK representatives for the medium to large scale commercial market for Flower Turbines.  Flower Turbines is the global leader in high-performance vertical axis wind turbines (VAWTs). ITS support EPC contractors, renewable energy installers, developers, and commercial organisations in integrating Flower Turbines’ innovative wind systems into  projects across the UK.

Whether you are enhancing an existing solar installation or designing a new multi-technology renewable system, Flower Turbines delivers a unique combination of efficiency, elegance, and outstanding performance—especially where traditional wind and solar solutions face limitations.

Additional information and technical specifications available on the Flower Turbines website. 

The Cluster Effect – Maximum Output From Minimal Space

One of the most powerful advantages of Flower Turbines is the Cluster (Bouquet) Effect.
Most wind turbines experience performance losses when installed close together. Flower Turbines do the opposite. With four turbines positioned together producing more than eight turbines separately.

FT 6M Flower Tulip Wind Turbine

Commercial-Scale Wind Power for High-Demand Sites

Our largest and most powerful Flower Tulip turbine, featuring a 5-metre blade height, is engineered to deliver serious commercial-scale wind generation. Designed for high-energy users, the FT 6M is ideal for projects where performance, reliability, and long-term ROI are critical.

This turbine is purpose-built to power large commercial and infrastructure assets, including:

• Shopping centres & retail parks

• Data centres

• Schools & universities

• Municipal buildings

• Warehouses & logistics hubs

• Airports

• Farms & agri-industrial sites

• And more

High Output, Exceptional Value

If you’re looking for up to 5 kW per turbine — and significantly more when deployed in a bouquet — this is the solution. The FT 6M is our most cost-effective Flower Tulip when measured by output per unit, making it ideal for scalable commercial installations.

Standard colour is white, providing a clean, architectural finish suitable for both urban and industrial environments.

Installation Options

The FT 6M is designed for:

• Ground-mounted installation

• Very strong roof structures (subject to structural and civil engineering approval)

Its robust construction and braking systems make it suitable for exposed and demanding sites.

Key Features

• 2-bladed Vertical Axis Wind Turbine (VAWT) for omni-directional wind capture

• Ultra-low cut-in wind speed for generation in light winds

• Bouquet Effect technology, delivering substantial output increases in clustered installations

• Designed for commercial, municipal, and infrastructure-scale energy systems

• Quiet operation with an iconic, architectural form
