20. PV simulator - input data and features
Functionality:
• PV technologies:
• Amorphous and crystalline silicon
• CIS/CIGS
• Fixed mounting
• Free-standing or roof-mounted
Input data - monthly averaged hourly values (12x24 values):
• Global irradiation
• Diffuse irradiation
• Air Temperature
+ Terrain elevation (and horizon)
Ouput data (12 monthly + 1 annual values)
• Solar electricity
• Performance Ratio

21. PV simulator - models
• Klucher’s model for calculating Global Tilted (in-plane) Irradiation
• Module temperature calculation for PV panels
• Ruiz-Martinez model for angular reflectivity
• King’s updated model for PV power conversion in DC modules
PV model is based on averaged hourly values
=> simplified approach, with higher uncertainty
