COTECH Solar

COTECH Solar is a Shanghai-based manufacturer that has been making solar cells, modules and complete solar systems since 2005. It's vertically integrated, which means the company handles cell production, panel assembly and system supply itself rather than buying parts in from several suppliers.

A few numbers give a sense of the size. COTECH has shipped around 20 GW of product to more than 800 customers in over 120 countries. Annual production capacity is 1.2 GW, and the company says it ranks among the top 50 solar manufacturers. It employs between 200 and 499 people across manufacturing, quality control, logistics and sales.

For most buyers, certification is the first question. COTECH's products carry TÜV, UL, IEC, VDE and CE certifications, which covers the marks that distributors and installers in Europe and North America usually ask for. The company's management systems are certified to ISO 9001 for quality and ISO 14001 for environmental management.

COTECH sells to businesses around the world. If you're a distributor, installer or project developer comparing suppliers, ask for datasheets, warranty terms and lead times on the exact module you need. Those details matter more than headline capacity when you're planning a real project.
