A STUDY ON INCREMENTAL CONDUCTANCE ALGORITHM FOR MAXIMUM POWER POINT TRACKING OF PHOTOVOLTAIC SYSTEMS

Today, the consumption and deploymentof conservativeenergy, & environmental pollution caused dueof it is increasing with the modernization of world. To minimize the pressure on conventional energy source it’s the need to have more concerned about looking alternative sources for power generation. Solar can play important role as an alternative energybeing a renewable energy source.Among the renewable resources, photovoltaic panels and wind-generators are primary contenders. The gainof Photovoltaic (PV) is that it has verysmallconversion efficiency, less maintenance &causes no pollution.The expenditureof solar system utilizing photovoltaic (PV)cellscan be reduced by using efficientpower systemwhich isdesigned to extortthe greatestprobable power from the photovoltaic module using sun tracking and maximum peak-power point track (MPPT) technique. In sun tracking technique PV panelis oriented according to sun within a day to generatea highestpossible power from it.To exploitthe increase in the extractionof electricity using photovoltaic (PV) systems, implementation of maximum power point tracking methodof photo-voltaicsystem using an incremental conductance algorithm, sun tracking technique and data loggingsoftware for monitoring the performance of solarsystemis presented in this work. In the photovoltaic (PV) systems, the instantaneousterminal voltage &output current are relianton the thermal energyand solarintensity. Thus, locating peakpower point is essentialfor accumulatingas much power as possible from solar panels
