Photovoltaic (PV)arrays have inconsistent output voltages due to a dependence on insolation, wind, and cell temperature. This causes the output power to vary from the maximum power the PV arrays are capable of providing to a load. An indirect method for tracking the maximum power point (MPP) of a PV array is presented. In order to maximize the output power of the PV array, a PIC microcontroller will be used to track the MPP of the solar array using characteristic equations from a curve fitting method that predicts the power versus voltage (P-V) curve for varying cell temperatures. This method approximates the P-V characteristic curve with a fourth-order polynomial. The coefficients of the approximated P-V characteristic curve were determined to be strongly dependent on cell temperature. The strong dependence of the P-V curve on cell temperature allows the P-V characteristic curve of a given system to be written as a function of both panel voltage and cell temperature. The proposed curve fitting method was verified using experimental data collected in the laboratory. Simulation results of the proposed method are also presented.

“…PV module has a similar pattern of P-V and P-I curve for different Irradiance value. A P-V curve is nonlinear in nature, and power can be given by polynomial function of voltage (Leedy and Garcia 2013;Khatib et al 2010). The approximate equation can be found out easily by hit and trial method or using iteration method.…”

The photovoltaic system is one of the renewable energy device, which directly converts solar radiation into electricity. The I-V characteristics of PV system are nonlinear in nature and under variable Irradiance and temperature, PV system has a single operating point where the power output is maximum, known as Maximum Power Point (MPP) and the point varies on changes in atmospheric conditions and electrical load. Maximum Power Point Tracker (MPPT) is used to track MPP of solar PV system for maximum efficiency operation. The various MPPT techniques together with implementation are reported in literature. In order to choose the best technique based upon the requirements, comprehensive and comparative study should be available. The aim of this paper is to present a comprehensive review of various MPPT techniques for uniform insolation and partial shading conditions. Furthermore, the comparison of practically accepted and widely used techniques has been made based on features, such as control strategy, type of circuitry, number of control variables and cost. This review work provides a quick analysis and design help for PV systems.
