This work represents an effective design of a temperature regulated PV module by integrating phase change materials for Malaysian weather condition. Through the numerical analysis and experimental investigation it has been shown that if a PCM layer of width 0.02 m of RT 35 is used as a cooling arrangement with a PV module, the surface temperature of the module is reduced by 10°C, which remains constant for a period of 4–6 hours. This reduction of temperature implies the increase in conversion efficiency of the module. Experiment as well as investigation has been carried out considering typical Malaysian weather. Obtained result has been validated by using experimental prototype and comparative analysis.

This paper represents a novel modeling technique of PV module with a fuzzy logic based MPPT algorithm and boost converter in Simulink environment. The prime contributions of this work are simplification of PV modeling technique and implementation of fuzzy based MPPT system to track maximum power efficiently. The main highlighted points of this paper are to demonstrate the precise control of the duty cycle with respect to various atmospheric conditions, illustration of PV characteristic curves, and operation analysis of the converter. The proposed system has been applied for three different PV modules SOLKAR 36 W, BP MSX 60 W, and KC85T 87 W. Finally the resultant data has been compared with the theoretical prediction and company specified value to ensure the validity of the system.

This paper represents a novel simulation approach of photovoltaic module with incremental conductance MPPT controlled buck-boost converter in simulink platform. Mathematical equations associated with the simulation process have been described with best clarity. Obtained results have been investigated to analyse the performance of the system using a SOLKAR 36 W PV module. This technique can also be used for the simulation of any specific PV module and converter with least changing in parameters.

Transformer-less inverters are more attractive for grid-tied photovoltaic (PV) system due to its higher efficiency and lower cost. But unfortunately, a leakage current flows through the system. So transformer-less PV inverter have to be tackled carefully. In this paper, a new transformerless PV inverter topology with low leakage current has been proposed. Proposed circuit structure and detail operation principle are presented in this paper. One additional switch with conventional full H-Bridge and a diode clamping branch make sure the disconnection of PV module from the grid at the freewheeling mode and clamp the short circuited output voltage at the half of DC input voltage. Therefore, the common mode (CM) leakage current is minimized. The relationship between H5 topology and proposed topology has been analyzed in this paper. The proposed inverter topology is simulated by MATLAB / Simulink software to validate the accuracy of the theoretical analysis. Finally, a 1kW prototype has been built and tested.

This paper represents a versatile simulation process of a photovoltaic module mainly using matlab function in simulink platform. To analyze the characteristics curves single diode circuit model and a SOLKAR 36 W PV module is used. The P-V and I-V curves obtained from this model for various radiations and temperature are investigated. This model can also be used for the simulation of any specified PV module with least changing in parameters.
