格鲁吉亚采购需求：太阳能电池板、太阳能发电系统、蓄电池、太阳能逆变器、太阳能配件

I'm looking for a comprehensive solution for a renewable energy system that includes a complete 3.9 MW setup along with a 1 MW storage solution. The installation is intended for a rooftop configuration, so I would like to ensure that the design is optimal for that specific application. Could you please provide detailed specifications, including the components involved, estimated timelines for delivery and installation, and any additional services like maintenance or monitoring options? I'm also interested in any relevant certifications or guarantees associated with the products. This project is significant for us, and I'd appreciate your prompt response with all necessary details. Thank you!
