PVWatts v.2: AC Energy report 0

Nomenclature

NºP.: Number of panels.
P.power: Power of the solar panel (Wp).
DC r.: DC rating (kWp).
DF: DC to AC Derate Factor (DC r. * DF = AC rating)
Energy (∑E_m): 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.
E_m: Average monthly electricity production from the given system (kWh/month).
E_d: Average daily electricity production from the given system (kWh/day). E_d= E_m/(month days).
H_d: Average daily sum of global irradiation per square meter received by the modules of the given system (kWh/m²/day).
H_m: Average monthly sum of global irradiation per square meter received by the modules of the given system (kWh/m²/month). H_m = H_d*(monthly days)
E_dy: Yearly average of E_d(kWh/day). E_dy= ∑E_m/(year days)
E_my: Yearly average of E_m (kWh/month). E_my=∑E_m/12
H_dy: Yearly average of H_d (kWh/m²/day).
H_my: Yearly Average of H_m (kWh/m²/month). H_my=H_dy*365/12
∑H_m: Yearly sum of H_m (kWh/m²/year). ∑H_m=H_dy*(year days)
