AbstractCurrent-Voltage (I-V) and Power-Voltage (P-V) characteristic of Photovoltaics (PV) modules are important issues in order to provide maximum power point (MPP) of PV. I-V and P-V characters are related to the environment, which certainly means that the efficiency of these cells affected by the environmental factors like temperature, radiation, dust, etc. Most recent trends in solar design use computer modeling to connect solar lighting systems, solar heat and ventilation considering weather data due to their effects on the solar cell performance. This paper presents the modeling and simulation of PV module using the MATLAB/ Simulink for calculating and plotting the I-V and P-V characteristics of PV module. Datasheet parameters of Mitsubishi PV-UD190MF5 PV module has been used for simulation. Effects of irradiance, temperature and connection types on the PV efficiency are investigated. The output performance of the PV panels is evaluated under different test conditions.
