Performance of Grid-connected PV
PVGIS estimates of solar electricity generation
Export document:
Nomenclature:
Tº: Estimated losses due to temperature (using local ambient temperature).
Refl.: Estimated loss due to angular reflectance effects.
Other: Other losses (cables, inverter etc.)
CSL: Combined PV system losses.
NºP.: Number of panels.
P.power: Power of the solar panel (Wp).
Power: Nominal power of the given system (KWp).
Energy: AC energy (kWh).
Yield: Ratio between power and energy (kWh/kWp).
Face: Number assigned to the face with the solar array. (Activate layer TX:Face_names to see what it is).
Group: Number of the group of solar panels with same tilt, azimuth and model.
Azimuth: Solar panel azimuth in grades.
Tilt: Solar panel tilt in grades.
Relative tilt: Angle between solar panel and roof in grades.
Shading losses = 100*(1 - solar energy that is potentially available at model site divided by the solar energy really receives solar panel due to shadows).
Solar Access =1 - Shading losses
Ed: Average daily electricity production from the given system (kWh/day).
Em: Average monthly electricity production from the given system (kWh/month).
Hd: Average daily sum of global irradiation per square meter received by the modules of the given system (kWh/m2/day).
Hm: Average monthly sum of global irradiation per square meter received by the modules of the given system (kWh/m2/month).
Edy: Yearly average of Ed (kWh/day).
Emy: Yearly average of Em (kWh/month).
Hdy: Yearly average of Hd (kWh/m2/day).
Hmy: Yearly Average of Hm (kWh/m2/month).
∑Hm: Yearly sum of Hm (kWh/m2/year).
