  20. 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 RatioSolar Atlas for the Mediterranean, Final Workshop, Amman, Jordan, 4 Dec 2012, www.solar-med-atlas.org 20
  21. 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 uncertaintySolar Atlas for the Mediterranean, Final Workshop, Amman, Jordan, 4 Dec 2012, www.solar-med-atlas.org 21
