NºP.: Number of panels.
P.power: Power of the solar panel (Wp).
DC r.: DC rating (kWp).
Energy (∑Em): Electricity production from the given system in one year (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.
ESL: Estimated system losses.
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
LID: Light-Induced Degradation. Em: Average monthly electricity production from the given system (kWh/month). Ed: Average daily electricity production from the given system (kWh/day).
Ed= Em/(month days).
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).
Hm = Hd*(monthly days) Edy: Yearly average of Ed(kWh/day).
Edy= ∑Em/(year days) Emy: Yearly average of Em (kWh/month).
Emy=∑Em/12 Hdy: Yearly average of Hd (kWh/m2/day). Hmy: Yearly Average of Hm (kWh/m2/month).
Hmy=Hdy*365/12 ∑Hm: Yearly sum of Hm (kWh/m2/year).
∑Hm=Hdy*(year days)

Caution: Photovoltaic system performance predictions calculated by PVWatts® include many inherent assumptions and uncertainties and do not
reflect variations between PV technologies nor site-specific characteristics except as represented by PVWatts® inputs. For example,
PV modules with better performance are not differentiated within PVWatts® from lesser performing modules.
