I'm interested in exploring the costs associated with wind turbines designed for residential use, specifically for a 5 kWh system. Could you provide detailed pricing for both the installation and necessary materials involved in this setup? Additionally, if you could include any information on available models and their features, that would be great. I'm looking to understand the overall investment required, so any insights into long-term savings or maintenance costs would also be appreciated. Thanks!
