"Three or five years ago, we did not dare to call ourselves a big country in photovoltaic technology, but now we can say that the gap with the world is getting closer and closer, and some technical fields are already ahead of the world. There are already production in China Enterprises with costs as low as US $ 15-25 are completely free of pollution, and even the level of technology far exceeds the level of the most advanced silicon material manufacturers in the world. "Jiangxi Saiwei LDK Solar High-Tech Co., Ltd. Chairman Peng Xiaofeng is proud of this. China's solar energy technology is also favored by the world's top 500 companies. Astec is a wholly-owned subsidiary of Emerson Electric Co., a Fortune 500 company, and is one of the world's largest power supply manufacturers. With its leading technology in photovoltaic terminal solutions and high-quality service system, Zhongsheng Optoelectronics Group has won The company provides solar rooftop photovoltaic power generation systems totaling 11.2 kilowatts. Despite the world's cutting-edge technology, it is worth noting that the huge local market that Chinese solar companies yearn for has never been properly exploited. China has already become the world's largest producer of solar energy, but 90% of China's solar energy is exported. But now this situation is changing.
