【 摘 要 】

Current-voltage (I-V) curves for photovoltaic (PV) modules representing all PV technologies were modeled by bilinearly interpolating the I-V curves from a PV module's four reference I-V curves. The interpolation was performed first with respect to open-circuit voltage to account for PV module temperature, and second with respect to short-circuit current to account for irradiance. The modeled I-V curves compared closely with measured I-V curves for 26 PV modules located at the National Renewable Energy Laboratory.
