Mathematical Modeling and Analysis of Solar PV System for UAV

Solar photovoltaic cell is the smallest unit of solar (PV) system. It converts light energy into electrical energy is termed as photovoltaic effect. In Modeling of PV system designers have great challenge to predict the expected power output under different environmental conditions. This paper present an analysis of PV module, based on the single diode model with series and shunt resistance. One diode equivalent circuit is employed in order to I-V and P-V characteristics of a 250 W solar module. The electrical model parameters of solar (PV) such as photocurrent, saturation current, series resistance, shunt resistance, diode ideality factor were constructed by simulations. The expected environmental output may results in decrease of output current and voltage due to the increase in the temperature of the solar PV panel. In order to track maximum power point tracking (MPPT) technique under varying insulation and shading conditions is used. PV arrays may be shaded by neighboring buildings power lines, trees, clouds, birds, grass. Due to the effect of partial shading on PV system characteristics and efficiency for different shading conditions and temperatures. Its characteristics and efficiency was experimentally found. The maximum power point of solar cells can be used on solar UAVs. The performance of the solar PV panel is analyzed by mathematical model for a solar photovoltaic cell using MATLAB R2014a.
