  3. Network of References under Monitoring (1) • 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) 3

  4. Network of References under Monitoring (2) • 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 4

  5. Worldwide Reference Network under Monitoring • 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! 5

  15. REFERENCES UNDER MONITORING Monitoring Components Irradiance cell (in module plane) Module temperature sensor Data logger Energy counter Inverter interface Ambient temperature sensor WAN/GSM Analogue signals Digital Signal (S0) www Bus (RS485) Database Web server / Portal 15

  16. References under Monitoring – Indicators • SPECIFIC ENERGY YIELD [kWh / kWp] • Energy feed into grid normalized to installed nominal (STC) module power • PERFORMANCE RATIO [%] • Irradiance sensor is needed to calculate PR! • Describes, how efficient the incoming irradiance energy is used • Performance Ratio = 100%: The entire system runs with nominal module efficiency 16

  17. Überwachung von Referenzanlagen – Kennzahlen • Loss factors: Inverter efficiency, wiring, low light behavior, temperature and shading • Common knowledge, annual PR > 80%: “Good” value 17
