Table 1 Influencing factors and variables for PV power generation.
Impact factor | An explanation of the meaning of words or phrases |
Temperature | Temperature in degrees Celsius (°C) corresponding to the point in time of the observation |
Array plane irradiance | The radiant power per unit area irradiated into the plane of a PV array, usually in watts per square meter (W/m²) |
Wind speed | Wind speed in meters per second (m/s) |
Relative humidity | The ratio of the temperature at which the air is saturated with water vapor content (dew point) to the corresponding temperature at the point in time of the observation, usually expressed as a percentage |
Actual power | Actual power output of the PV system at a given point in time, in kilowatts (kW) |
