A Global Solar Leader Addressing the 21st Century’s
Energy Challenge

Suntech develops, manufactures, and delivers the world’s most reliable and cost-effective solar energy solutions. Founded in 2001 by leading solar scientist Dr. Zhengrong Shi, we are the world’s largest producer of silicon solar modules.

We offer clean power for every application and market, from off-grid systems, to homes, to the world’s largest solar power plants. Our solar modules are installed in over 80 countries.

Suntech has offices in 13 countries, including regional headquarters in San Francisco, California; Schaffhausen, Switzerland; and Wuxi, China. We are listed on the New York Stock Exchange (NYSE: STP).

World-Class Manufacturing

State-of-the-art manufacturing lies at the core of Suntech's business and enables us to deliver high-quality solar products to our customers at an affordable price. Our 2-Gigawatt manufacturing capacity makes Suntech the largest module manufacturer in the world, allowing us to offer advanced products and leverage economies of scale. Suntech manufacturing sites, located in China, Japan and the United States, follow the strictest production guidelines and are staffed by highly-trained manufacturing experts.


Suntech solar cells undergo a chemical surface micro-texturing process that improves their ability to capture light. The cell production facility employs industry-leading manufacturing techniques to create high conversion efficiency solar cells.


Cells with similar electrical characteristics are matched during module assembly to minimize efficiency losses.  Laminated modules are equipped with corrosion-resistant frames and weather-proof electrical components to create a durable, water-tight product. 


Our quality control program features 52 tests and checks throughout the cell and module manufacturing process. Once fully assembled, all Suntech modules undergo a final performance test and are categorized based on power and current production. Our rigorous review process ensures we deliver only the highest quality products to our customers.

Environmental Responsibility in Action

Suntech is a proactive policy advocate and a supporter of numerous environmental awareness initiatives, and works with numerous organizations to advance environmental stewardship across the world.
  • Suntech, certified with OHSAS 18001, is committed to the highest occupational health and safety management standards. To minimize or avoid accidents, incidents, injuries or occupational hazards, Suntech prioritizes health and safety in all operations through the implementation of effective safety procedures and precautions.
  • SA 8000 is broadly recognized by trade unions and NGOs as one of the strictest workplace standards worldwide. It is a global certification system used by leading companies to assess, monitor and influence social accountability. The standard focuses on the areas of health and safety, freedom of association, protection against child labor or forced labor, protection from discrimination and disciplinary practices, the promotion of fair working hours and fair remuneration as well as effective management and implementation. Suntech is committed to these international social responsibility standards for employees, customers and suppliers through strict and continued compliance. SA8000 compliance was audited and certified by BV International in September 2010.
  • Suntech’s manufacturing process adheres to the highest international environmental protocols, and is certified with ISO 14001 Environmental Management Standards.
  • In 2008, Suntech joined The Climate Group and Copenhagen Climate Council to collaborate with some of the world's brightest environmental and business minds and develop practical solutions for the reduction of greenhouse gas emissions.
  • In early 2009, Suntech proudly opened our new state-of-the-art headquarters in Wuxi, China, which has become an example of the potential of solar power.  The headquarters is powered by one of the world’s largest on-grid solar façade systems and is designed to be 80% energy self-sufficient.
  • Suntech participates in the World Wildlife Fund’s Earth Hour Campaign to support energy conservation, and joined the European PV CYCLE association, which is engaged in establishing a voluntary take-back and recycling program for end-of-life solar modules.

Corporate Responsibility around the Globe

The promise of solar power is critically important to solving today’s energy demands in an environmentally sensitive way. Solar energy offers unparalleled potential for developing nations, where a lack of reliable electricity has stunted education, research and economic development efforts. Suntech has worked with partners in several developing countries to harness sunlight for transformative projects that power schools, NGOs and non-profit institutions.
