At the end of 1999 Q.CELLS started its production of silicon solar cells in the first half year of 2001 with only 19 employees. Now over 2000 people work for Q.CELLS. Since its founding, Q.CELLS has developed from one of the world’s largest solar cell manufacturers to a leading photovoltaics company within a few years. The extensive product portfolio ranges from solar cells, crystalline and thin-film solar modules to complete photovoltaic systems.
Q.CELLS develops and produces its products at the group's head office Bitterfeld-Wolfen, Germany as well as in Malaysia and markets through a global network of distributors. Q.CELLS backs up these advantages with guarantees which are unique compared with other competitors. A linear performance guarantee for 83% after 25 years with crystalline solar modules or 85% with CIGS thin-film modules.
