Solar energy optimization using MPPT controller by maximum conductance method

Increase of load and demand factor on power grids has made supply of electric power to rural areas as a big challenge. The idea of increasing the number of power plants could not be much efficient because it increases the emission of carbon and production cost. Hence use of renewable power sources seems to be much more efficient. The main motive of this proposed work is an efficient design of solar panel for constant Current-Voltage (V-I) characteristics of a Photovoltaic array of various environmental conditions like different irradiance and temperature. A proposed model uses constant environmental condition in combination with actual solar radiation and ambient temperature. The new design is developed on Mat lab-Simulink platform for calculating and analyzing the power output from a PV panel by taking the values of current and voltage with constantly varying solar radiation at any geographical location and different day The output power of solar panel is directly given to dc /dc controller in order to reduce circuit complexity. The estimation of MPP (maximum power point) of a Photovoltaic (PV) array is done by calculating the value of both ampere, voltage and power curves for changing environmental conditions.
