The PV characteristic curve, which is widely known as the I–V curve, is the representation of the electrical behavior describing a solar cell, PV module, PV panel, or an array under different ambient conditions, which are usually provided in a typical manufacturer’s datasheet.
Thus, in order to reduce the effect of solar irradiance and temperature fluctuations, several techniques are used to automatically measure the I-V characteristic of PV modules. Cotfas et al. used the capacitor charging cycle as an automatic variable load to measure the PV cell I-V curve by about a hundredth of a second.
Therefore, this review paper conducts an in-depth analysis of the accuracy of PV models in reconstructing characteristic curves for different PV panels. The limitations of existing PV models were identified based on simulation results obtained using MATLAB and performance indices.
4. Conclusion The implemented PV I-V curve tracer allows to scan the entire current-voltage characteristic by one msec per (I, V) point. As a result, the entire I-V characteristic is collected, under real operating conditions, at constant temperatures and constant solar irradiance.
The operating temperature (T) and solar irradiance (G) have important effects on PV modules performances. PV module operating temperature is given as a function of ambient temperature (Ta) and solar irradiance , , according to the equation: (9) T = [(T NOCT - 25) / 800] G + T a where TNOCT is the nominal operating solar cell temperature.
To characterize a PV module under these conditions, the measure of the entire current-voltage (I-V) curve in short time requires a suitable data acquisition device. This paper outlines the features of a low-cost acquisition device to characterize a PV module under real operating conditions.
