JA Solar was founded in China in 2005 and has now become a leading player in the photovoltaic industry. The company has built a complete vertical production chain - producing silicon rods, wafers, cells and modules.

JA Solar's product portfolio ranges from residential rooftop solar systems to commercial and utility-scale power plants. Its modules feature cutting-edge technologies, such as the TOPCon cell "DeepBlue 5.0" series, which can achieve conversion efficiencies of up to 24.8%. The company also places a strong focus on energy storage ("PV + Storage"), so that solar power generation is not only feasible but can also be effectively integrated into the energy system.

JA Solar operates globally, with products sold in over 130 countries and manufacturing facilities in several countries (e.g. China, Vietnam). The company's strategy also includes sustainability and carbon-neutrality, for example by becoming a member of the World Business Council for Sustainable Development.
