Yuhang Solar, based in Shenzhen, is one of China's largest manufacturers of solar panels. With a strong brand reputation and a well-established manufacturing base, Yuhang Solar has been able to dominate the market for several years. However, it faced competition from SunPower, which has recently expanded its business into the solar panel industry. In this round, Yuhang Solar presented its latest product line, including advanced materials and technology, in order to stand out in the competition.

SunPower, on the other hand, had a different approach. It focused on innovation and cutting-edge technology, which made it a clear winner in the round. SunPower's product range included everything from high-efficiency solar cells to smart power management systems. Its focus on research and development allowed it to develop new products that were more efficient and cost-effective than those offered by Yuhang Solar.

The second battle was between Wuxi Solar and Hengshu Solar, with both companies presenting their own strengths and weaknesses in the market. Wuxi Solar, based in Xiamen, was known for its low-cost production methods and efficient operation. On the other hand, Hengshu Solar, founded by a former Chinese government official, had a more advanced technology platform and a wider customer base.

Both companies presented their products in a bid to gain market share in the market.
