“…In order to determine the link between the power output and the voltage input of a solar cell, the incremental conductance method makes use of the slope of the power-voltage (P-V) curve. Maximum power is reached at a voltage of zero, with the voltage increasing when the slope is positive and decreasing when the slope is negative [31].…”

It is proved and examined in this research paper that the perturb and observe (P and O) technique for isolating the photovoltaic array (PVA) from the power structure may be used to isolate the PV array from the power structure. A single specified voltage setup can remove the maximum power from a PV cell because of the nonlinear properties of the PV cell’s output. As a result, in PVA, the maximum power point tracking (MPPT) algorithm is utilized to increase the yield control range by increasing the maximum power point. In this study, the MPPT computations are carried out with the assistance of a DC-DC boost converter for usage in applications needing high voltage gain at a variety of sun-positioned irradiances and cell temperatures, as demonstrated in the literature.

“…Photovoltaic systems have been incorporated into the island DC microgrid architecture [1] and residential microgrids [2][3][4][5] due to their good dynamics and the maximum power point tracking (MPPT) algorithms used to extract the maximum available power from photovoltaic (PV) module [6][7][8]. Numerous MPPT methods have been studied and implemented, which can be broadly categorized as direct and indirect methods [9].…”

This paper presents an optimal design of a surface-based polynomial fitting for tracking the maximum power point (MPPT) of a photovoltaic (PV) system, here named surface-based polynomial fitting (MPPT-SPF). The procedure of the proposed MPPT-SPF strategy is based on a polynomial model to characterize data from the PV module with a global fit. The advantage of using polynomials is that they provide a good fit within a predefined data range even though they can diverge greatly from that range. The MPPT-SPF strategy is integrated with a DC-DC boost converter to verify its performance and its interaction with different control loops. Therefore, the MPPT strategy is applied to the reference outer PI control loop, which in turn provides the current reference to the inner current loop based on a discrete-time sliding current control. A real-time and high-speed simulator (PLECS RT Box 1) and a digital signal controller (DSC) are used to implement the hardware-in-the-loop system to obtain the results. The proposed strategy does not have a high computational cost and can be implemented in a commercial low-cost DSC (TI 28069M). The proposed MPPT strategy is compared with a conventional perturb and observe method to prove its effectiveness under demanding tests.

“…A low-power solar charger is the paper [39], in which an 18 V 40 W photovoltaic panel was used to carry out the process of charging a 12 V battery using the MPPT method. Another example [40] includes a 21 V photovoltaic panel with a power of 30 W was used to charge a single Li-Ion cell. In both cases, the possibility of using the MPPT method was presented in an experimental way, presenting the loading process.…”

The use of solar panels in low-power applications is an increasingly developing topic. Various methods are currently used to obtain the highest possible solar panel power generation efficiency. The methods of determining the maximum power point (MPP) and its tracking are under constant development, resulting in the creation of new algorithms to accelerate the operational efficiency while maintaining good parameters. Typically, these methods are only used in high-power photovoltaic installations. Due to the problems resulting from the adjustment to MPP working conditions for low-power solar panels used to charge a Li-Ion battery, an attempt was made to check the feasibility of operating control based on a Pulse Width Modulation (PWM) method and a Maximum Power Point Tracking (MPPT) algorithm like the one used in high-power solar systems also for low-power systems. The article presents adaptation of PWM and MPPT methods for small chargers, including the stages of modelling a solar charger and the results of a computer simulation of the charger operation. The stages of building a real, physical device are also presented. From the analysis of the test results of the constructed charger in real- and laboratory conditions with the use of a device imitating sunlight, the so-called solar box, and comparisons with computer simulations show that the assumed goal was achieved. The results obtained with the PWM method were compared with the MPPT method. The optimization of the device operation parameters and improvement of the algorithms used in the MPPT method resulted in better optimalization of maximum point tracking, improving the efficiency of energy storage from solar cells.
