Claim 0:
1. A method of tuning a system performance model for a power plant, the power plant comprising at least one solar panel array, an inverter electrically coupled to the at least one solar panel array, and a power controller including an error processor, the method comprising:
training the system performance model using default parameters;
estimating an expected output of the inverter using the system performance model;
obtaining a measured output of the inverter;
calculating, by the power controller, a difference between the expected output of the inverter and the measured output of the inverter;
determining, by the error processor, whether the difference represents a modeling error or a performance issue; and
in response to determining that the difference represents the modeling error, tuning the system performance model using the difference for subsequent use of the system performance model for estimating the expected output of the inverter.
