Overview
JA Solar Technology Co., Ltd. ("JA Solar") is a leading global supplier of photovoltaic ("PV") power generation solutions. Mr. Baofang Jin, the founder and chairman of the Board of the company, led the pioneering entry into the PV industry in 1996, with an initial focus on the silicon rod and silicon wafer business. In 2005, he founded JA Solar to begin manufacturing solar cells. The company was listed on NASDAQ in 2007. By 2010, JA Solar had extended its industrial chain downstream to include modules, and in 2012, it further expanded to PV power generation, thereby having established a vertically integrated production chain. After privatizing and delisting from NASDAQ in 2018, JA Solar completed its A-share listing on the Shenzhen Stock Exchange in 2019 (Stock Code: 002459). The company’s birthplace and place of registration for the listing are both in Ningjin County, Hebei Province. JA Solar has established multiple production bases globally and owns 16 sales companies overseas. It has built a comprehensive new energy industry chain encompassing silicon wafers, cells, modules, energy storage systems, PV power station development and operation, as well as PV materials and equipment. JA Solar's products are sold and serviced in 178 countries and regions worldwide. In 2024, achieving cells and modules shipments set a record high for the company. As of the end of the first quarter of 2025, the cumulative shipment volume of cells and modules has exceeded 280GW, ranking among the top global companies for many consecutive years.
