Performance Ratio Calculation by Trackso
Seasonal variation of the traditional PR is removed by calculating a temperature-corrected performance ratio: PR'' STC = (Eout / Ck P0) / (Hi / Gi,ref ) with. Ck = 1 + γ × (Tmod,k – Treference) Using 25 °C as Tref gives PR''STC. This term Ck corrects for the difference between the actual temperature and STC temperature used for power rating.
