I'm planning to set up a windmill power system at my farmhouse in Memon Goth, Karachi, primarily for personal use. I'm interested in exploring different options available for windmill systems that can produce outputs of 7 kV and 15 kV. It would be great if you could provide details on the various models suited for these capacities, along with their key features. Additionally, please include estimated costs for the different options, as well as any recommendations you might have based on efficiency and durability. If there are any installation services or maintenance packages available, I'd love to hear about those too. Looking forward to your prompt response!
