eng.PV-panel-temperature-correction Calculator
Calculates PV panel power output correction for operating temperature from the temperature coefficient of power. PV panel efficiency decreases approximately 0.4–0.5%/°C above the STC temperature of 25°C — a panel at 65°C loses 16–20% of rated output.
Inputs
P Stc W
Rate of energy transfer (W). P = V×I (electrical). P = F×v (mechanical). 1 horsepower ≈ 746 W.
Noct C
Reference formula or conversion factor shown for context.
T Amb C
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
G W M2
Reference formula or conversion factor shown for context.
Pmax Tc Pct C
Reference formula or conversion factor shown for context.
Results
actual output power (W)
Reference formula or conversion factor shown for context.
cell temperature (°C)
The value at the specified point or condition.
temperature power loss
The decrease or degradation from the baseline.
T_cell = T_amb + (NOCT−20) · G/800
Sample size or count used in the calculation.
P = P_STC · (1 + TC · ΔT) · G/G_STC
Reference formula or conversion factor shown for context.
