“…For instance, reciprocal of slopes at the open circuit and short circuit conditions are used to estimate R s and R p . On the other hand, the knowledge that slope of the power curve at MPP equals to zero serve as a reference to adjust the values of several parameters [24,25]. In some cases, the analytical expressions for open circuit temperature coefficient (K v ) [26] and short circuit temperature coefficient (K i ) are used to provide information required to compute the parameters analytically [27].…”

“…The simplest method is constant parameter modelling [24], where it is assumed that only I PV and I 0 are affected by the environmental conditions, while others, namely a, R s , and R p , are considered constants for a determined condition [12]. However, keeping a majority of the model parameters constant is too idealistic-considering the fact that physically, they are highly sensitive to G and T variations [28,29].…”

“…For verification purpose five different PV modules (monocrystalline, multi-crystalline, and thin film) were used. The experimental data used to verify the model are collected from manufacturer datasheets and from [4,9,10,11,12]. The datasheet values for these modules under STC are shown in Table II.…”

“…The influence of R s becomes stronger on the direction to the open circuit condition, while R p shows a strong influence in the direction to the short circuit condition. Some authors [4,5,6,7] neglect R p to simplify the model, as it has a high value. Simultaneously, other authors neglect R s because of its low value.…”

This paper study the effect of redistributing the series resistance in the two-diode model of the PV module according to its physical components, considering the relation of each component to temperature variation. The proposed model divide the series resistance into two materials: metal and semiconductor, constructing the mathematical model for the overall model. The model is found to improve the accuracy in calculating the maximum power point with temperature variation, which contribute to the job of PV power converter designers and circuit simulator developers.

The proposed scheme is based on the modified perturb and observe (P&O) algorithm combined with the sliding mode technique. A modified P&O algorithm based sliding mode controller is developed to study the effects of partial shade, temperature, and insolation on the performance of maximum power point tracking (MPPT) used in photovoltaic (PV) systems. Under partially shaded conditions and temperature, the energy conversion efficiency of a PV array is very low, leading to significant power losses. Consequently, increasing efficiency by means of MPPT is particularly important. Conventional techniques are easy to implement but produce oscillations at MPP. The proposed method is applied to a model to simulate the performance of the PV system for solar energy usage, which is compared to the conventional methods under non-uniform insolation improving the PV system utilization efficiency and allowing optimization of the system performance. The modified perturb and observe sliding mode controller successfully overcomes the issues presented by non-uniform conditions and tracks the global MPP. Compared to MPPT techniques, the proposed technique is more efficient; it produces less oscillation at MPP in the steady state, and provides more precise tracking.
