From Iskra AT5 to Evance R9000, and now Britwind H5: A Legacy of Wind Power Innovation

The Iskra AT5 was a pioneering 5kW wind turbine renowned for its robust performance and reliability. Widely installed across residential, agricultural, and commercial sites, it set a high benchmark in small wind turbine technology.

Building on the success of the AT5, the Evance R9000 further advanced turbine efficiency, particularly excelling at capturing energy from lower wind speeds. It became well-known for its innovative design and dependable operation across diverse settings.

Today, the legacy continues with the Britwind H5, incorporating and enhancing the best features of its predecessors, delivering outstanding performance and reliability in a modern, efficient package.

Key Features Across Generations:

• High Efficiency: The Evance R9000 improved upon the AT5, starting power generation at wind speeds as low as 2.5 m/s (5.6 mph), with no cut-out wind speed. The Britwind H5 maintains this standard, ensuring continuous, efficient operation.

• Innovative Technology: The Evance R9000 introduced the patented Reactive Pitch™ technology, optimising blade positioning to maximise energy yield and control blade speed during high winds—a feature retained and refined in the Britwind H5.

• Robust Construction: Originally developed in the Iskra AT5, durable construction was enhanced in the Evance R9000 through advanced materials, including UV-resistant and anti-erosion coatings on glass fibre reinforced composite blades, ensuring longevity and reliability—qualities fully preserved in the Britwind H5.

• Low Maintenance: The direct-drive, gearbox-free design, first established in the Evance R9000, remains a key feature of the Britwind H5, significantly reducing maintenance requirements and enhancing reliability.

• Quiet Operation: Both the Evance R9000 and now the Britwind H5 are engineered for minimal noise, using advanced blade design and direct-drive technology to eliminate gearbox noise, offering a quiet and efficient energy solution.

Performance:

The Evance R9000 demonstrated its capability by generating approximately 9,167 kWh annually at an average wind speed of 5 m/s (11.2 mph), making it a substantial contributor to energy requirements—a performance standard that Britwind H5 matches or surpasses.

Applications:

Across its iterations, from Iskra AT5 and Evance R9000 to Britwind H5, these turbines have proven ideal for:

• Residential wind power: Providing homeowners with renewable energy solutions to reduce electricity costs and environmental impact.

• Wind turbines for agricultural settings: Helping farms improve sustainability, reduce operational costs, and reliably power essential equipment.

• Wind turbines for businesses: Allowing businesses to meet sustainability targets, improve energy independence, and significantly lower energy expenses.

Investing in the Britwind H5 continues a proven tradition of achieving energy independence, cost savings, and contributing positively to environmental sustainability through reliable, efficient wind energy.
