Miyazaki City in Japan has a climate of the South China Sea type, with long sunshine hours. It is warm like spring all year round and has sufficient sunshine. The annual sunshine hours are about 2000 hours, providing sufficient development space for solar photovoltaic power generation. Overseas container transportation is the main mode, so this project also adopts an innovative vertical packaging transportation solution: compared with traditional horizontal packaging, it can increase loading capacity by 10%, improve container space utilization by 5%, and maximize the utilization of container space.
