With the rapid development of the global economy, solar photovoltaic, as a clean, low-carbon energy, is playing an increasingly important role in my country’s energy system. The solar photovoltaic industry of China is the largest , and its newly installed capacity ranks first in the world for many consecutive years. "This is a critical period for my country's energy transition and a critical period for the sustainable and healthy development of the photovoltaic industry. Problems in energy consumption and environmental pollution have emerged one after another. The report of the 19th National Congress of the Communist Party of China pointed out the direction and route for China to promote ecological civilization and green and low-carbon development in the future. The "2021 Western China (Chengdu) International Solar Photovoltaic and Energy Storage Technology and Equipment Exhibition" hosted by the Guangdong Solar Energy Association, the Solar Energy Research Institute of Sun Yat-sen University in Shunde, and Guangdong Hongwei International Convention and Exhibition Group Co., Ltd. is based on the industry’s advanced applicable technologies and products. Relying on the purpose of launching new products, demonstrating new technologies, and promoting new service models, it promotes technological docking, achievement transformation and product transactions of exhibiting companies, and creates a brand event with efficient docking of resources.
