西班牙采购需求：控制器逆变器、发电机、水平风力涡轮机、太阳能电池板、垂直风力涡轮机、风力涡轮机玩具

I'm interested in sourcing two units of a vertical wind generator with a capacity of 3 kW. I'm keen on exploring eco-friendly solutions, so please provide details about the product specifications, including material quality, efficiency ratings, and any certifications that indicate environmental compliance. Additionally, I'd appreciate it if you could include pricing information, options for bulk orders, and lead times for delivery. If there are any warranties or after-sales services available, please share those details as well. Looking forward to your prompt reply!
