... When the temperature of a so PV module is increased, the efficiency drops. This can usually result in an efficiency drop off of 0.5% per °C progress in the cell operating temperature [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40]. The working temperature is increased because a great part of solar radiation is not changed to electricity but is absorbed by panel as heat. ...
It is a well-known fact that the dependency of non-renewables sources needs to be reduce to deal with global warming. Solar energy is one such option which is in abundance in India. Solar PV cell are utilised to trap this energy and convert it to electrical energy. The PV cell has the ability to convert near about of 20 % of solar energy to electrical energy. The output of PV cell depends on solar irradiation and panel temperature and panel terminal voltage, based on which MPP can be attained. Hence work is to be done to achieve that point operation for MPPT.This work presents a comparative study between two maximum power point tracking (MPPT) methods in MATLAB/Simulink program that are incremental conductance method and genetic algorithm-based method. The study is performed with variable irradiation and temperature. On simulation, the results obtained are found to give boost converted output voltage of 502.13 V for ANFIS MPPT method and 501.50 V for INC MPPT method. In addition, the output power of boost converter for variable irradiation is found out to be 92.26 KW for ANFIS and 90.41 KW for INC respective only comparison results, ANFIS has clear upper hand over P&O method in terms of performance.

The solar PV system is one such option, which is gaining its contribution globall y each year. Its increase in popularity is due to a reduction in its cost due to technological enhancement. At present globally, 4800 GW is generated using Solar PV. A growth of around 60% was observed in the case of grid-connected solar PV systems; at present contributing around 21 GW.Even today, the majority of energy generation done using non-renewable energy sources due to the cost of generation. However, these sources lead to a major threat of global warming. Furthermore, these sources are responsible for a variety of additional types of pollution, all of which contribute to ecologi cal degradation. As a result, renewable energy sources such as solar are becoming more important. In a country like India, solar radiation is abundant throughout the country at most times of the year.Furthermore, turning solar energy to electrical energy is a rather simple procedure. Solar PV systems that are both grid-connected and dispersed have significant advantages. Because of the large potential of solar energy in the Indian subcontinent, the Indian government has set a goal of achieving a defined limit of renewables in India of roughly 175 GW by 2022, with solar-based systems accounting for around 65 percent of the absolute limit. The goal of this project is to learn about MPPT and how to apply it to a PV panel in Matlab software to determine where the P V panel will give the most power. 2.Literature review The detailed literature review in the area of PV solar, other renewable energy resources and MPPT method/techniques to track maximum power are presented in this chapter. The various studies show that a solar panel converts 21-40% of energy incident on it to electricalenergy. A Maximum Power Point Tracking algorithm is necessary to increase the efficiency of the solar panel. Yong Li, Sarminah Samad [1] in 2020 discussed the use of a combined system for generating power had expanded dramatically. The combination of a photovoltaic (PV) system and an energy storage system has gotten a lot of interest in this regard. In this regard, this stu dy presents a control system for a grid-connected combined energy system that consists of a PV and a battery.. Xun Ge et al. [2] in 2020 discussed that the paper develops a control scheme for a hybrid energy system, including a photovoltaic (PV) panel and a battery energy storage (BES) system. The capital cost of PV systems is considerably high today and it has been continuously t rying to mitigate the manufacturing cost and also, several research works have been devoted to developing effective methods to maximize the power output of these generation systems. Maximum power point trackers (MPPT) are necessary to achieve optimal solar power, according to N. Priyadarshi et al. [3] in 2019. This work proposes an intelligent fuzzy particle swarm optimization (FPSO) MPPT algorithm to accomplish this goal. A ripple factor compensation-based modified space vector pulse width modulation (SVPWM) approach was also used to gate an inverter control scheme. The suggested system's
