I am interested in a small vertical wind turbine with a spiral design, ideally suited for residential or small scale applications. Specifically, I'm looking for a model that can generate around 1KW of power. It should be efficient, reliable, and capable of operating in various wind conditions. If you could provide details on your available options, including specifications, features, and pricing, that would be great. Additionally, I'm keen to understand more about the installation requirements and any maintenance services you offer. Please include information regarding the warranty period and any certifications the product might have. Looking forward to hearing from you soon!
