I am looking for a home wind turbine fan setup with a power output ranging from 6 to 7 KW. It's essential for this setup to be efficient and reliable, as it will be used to generate renewable energy for residential use. I'm particularly interested in the turbine's design to optimize energy capture even in low-wind conditions, and I would appreciate details on the materials used for durability. Additionally, please provide information on the installation process, including the necessary components and any maintenance requirements for optimal performance. It would be great to understand the pricing structure and any available options for customization, as well as lead times for delivery. If you have any technical specifications or brochures, please share those too. Looking forward to your prompt response!
