The carbon footprint of module making is the total Greenhouse Gas (GHG) emissions at each life-cycle stage. It involves raw material extraction, processing, manufacture, transport, installation, and disposal. High energy requirement for polysilicon production is the biggest factor because of using coal-fired power plants. Moreover, wafering, cell fabrication, and module assembly are energy-intensive processes and require chemicals that emit CO2. Solar modules offset operational emissions. Still, initial energy input, supply chain emissions, and end-of-life disposal impact their carbon footprint.
DAS Solar is dedicated to integrating sustainability and environmental responsibility across all stages of its module life-cycle. From design, manufacturing, supply chain management, project implementation to recycling, the company employs a holistic strategy to minimize its carbon footprint and promote green energy solutions.
DAS Solar's modules are designed with environmental impact in mind. The company is spearheading Design for Recycling (DFR) principles, focusing on material reduction in key components such as wafers, cells, and silver paste. Through green eco-design, hazardous substance substitution, wafer thinning, and advanced manufacturing processes, the company aims to minimize waste at the source. Its lightweight modules, for instance, are 100% recyclable and have a carbon footprint 17.3% lower than conventional modules. By replacing conventional back sheets with a self-developed high-polymer fluorine composite, the module weight is cut by over 70% with less transport emissions. N-type modules stand out with their superior energy efficiency and low carbon footprint as well. Thanks to advanced technologies such as TOPCon 4.0 Plus and the innovative 0BB design, these modules offer higher power generation efficiency with reduced silver consumption and material waste.
At the heart of DAS Solar's operations is a commitment to green manufacturing. The company has established TÜV SÜD certified zero-carbon factories in Quzhou and Zhangzhou, which utilize intelligent energy management to optimize resource use and reduce waste. These facilities have earned ISO-14064 GHG verification, demonstrating their ability to accurately measure and reduce emissions throughout its operations. The company also received the French ECS Carbon Footprint certification and Italy Environmental Product Declaration (EPD) certification which involve the evaluation of a product's environmental impact throughout its entire life-cycle. Aiming to achieve carbon neutrality at its manufacturing sites by 2030 and across the entire operations by 2050, DAS Solar implements energy-efficient production processes and prioritizes the use of renewable energy sources, significantly lowering the carbon footprint associated with module manufacturing.
Understanding the importance of a sustainable supply chain, DAS Solar actively collaborates with upstream and downstream partners to foster a green industry ecosystem. To enhance supply chain transparency, the company obtained the STS Transparent Supply Chain certification, ensuring that all raw materials, components, and manufacturing processes comply with strict environmental and social standards. Recently, DAS Solar has joined the Solar Stewardship Initiative (SSI), which marks another step forward in its commitment to responsible supply chains. By virtue of transparent supply chain audits and the implementation of traceability systems, the company was named on MIIT's List of Green Supply Chain Management Enterprises this year, meeting rigorous environmental standards at every stage, from raw material sourcing to transportation and logistics.
Beyond design, manufacturing and supply chain, DAS Solar's modules contribute to environmental preservation in their applications. Currently, the company's TOPCon 5.0 cells have surpassed 26.9% efficiency with an open-circuit voltage of 746mV, setting multiple world records and solidifying the company's leadership in N-type TOPCon technology. Amid increasingly fierce competition in the solar market, DAS Solar has leveraged its technological and resource advantages to create all-scenario solutions for urban, ecological, and floating applications. By combining flexible mounting systems, lightweight modules, and all-black modules, the company has broadened the application fields of its "PV+" products. These achievements speak for the company’s substantial contribution to global decarbonization efforts.
Among the first to introduce the DASGREEN initiative, DAS Solar is also actively advancing module recycling to promote a more sustainable PV industry. The company has established a comprehensive end-of-life recycling system for modules, focusing on recovering high-value materials such as silicon, glass, and metals through environmentally responsible processes. By collaborating with certified recycling partners and integrating circular economy principles into its product design and life-cycle management, DAS Solar aims to minimize environmental impact and resource waste.
Through its comprehensive low-carbon strategy, DAS Solar exemplifies how integrating sustainability into every phase of the module life-cycle can lead to significant environmental benefits. By combining green manufacturing, transparent supply chains, eco-friendly product design, and sustainable project applications, the company is reinforcing its position as a leader in the solar sector while driving forward the global transition to a net-zero future.
