Information

Hypothesis and equations

This model uses a simple equation to determine the electrical efficiency of the PV panel according to the temperature:

eta_T=eta_STC+mu_T*(T_cell-T_STC)

mu_T is the temperature coefficient on the power (of the order of -0.5%/K) and STC means Standard Testing Conditions.
