3. Network of References under Monitoring (1) 3 Why reference monitoring? In reality, STC conditions almost never occur…  Crucial is the performance under real conditions, in different applications and segements!  Monitoring and development of Q-Cells products under real conditions (ex. Anti PID- Technology)

4. Network of References under Monitoring (2) 4 Why reference monitoring? Benefits for you:  Improved performance calculations due to energy yield simulation under real life conditions  Optimisation of system design and installation based on real performance data  Broad reference data base for installation benchmarking

5. Worldwide Reference Network under Monitoring 5  Currently about 68 reference sites under monitoring  Covering nearly all climate conditions, applications, and segments We need you to further build up the worldwide network!
