MARATHE.V.R Assistant professor, ENTC department, N.B.N.Sinhgad college of engineering, Solapur ABSTRACT Today, the consumption and deployment of conservative energy, & environmental pollution caused due of it is increasing with the modernization of world. To minimize the pressure on conventional energy so urce it’s the need to have more concerned about looking alternative sources for power generation. Solar can play important role as an alternative energy being a renewable energy source. Among the renewable resources, photovoltaic panels and wind- generators are primary contenders. The gain of Photovoltaic (PV) is that it has very small conversion efficiency, less maintenance & causes no pollution. The expenditure of solar system utilizing photovoltaic (PV) cells can be reduced by using efficient power system which is designed to extort the greatest probable power from the photovoltaic module using sun tracking and maximum peak-power point track (MPPT) technique. In sun tracking technique PV panel is oriented according to sun within a day to generate a highest possible power from it. To exploit the increase in the extraction of electricity using photovoltaic (PV) systems, implementation of maximum power point tracking method of photo-voltaic system using an incremental conductance algorithm, sun tracking technique and data logging software for monitoring the performance of solar system is presented in this work. In the photovoltaic (PV) systems, the instantaneous terminal voltage & output current are reliant on the thermal energy and solar intensity. Thus, locating peak power point is essential for accumulating as much power as possible from solar panels. KEYWORDS: Maximum power point tracking (MPPT), Perturbation and observation (P & O), and Incremental conductance (InC). INTRODUCTION Since the late twentieth century, global warming and energy shortage are becoming serious issues. Solar power is a substitute technology that will optimistically guide us away from our combustible fuel dependent energy sources. In response to these issues, clean and renewable energies such as solar power, wind power, or tidal energy are receiving great interests in recent years. The solar as a source has the advantages of being inexhaustible and noiseless, and no mechanical power generator is required. Therefore, photo-voltaic (PV) system has fascinated more attention. The ultimate aim of the progress of solar systems is maximizing the effectiveness of power conversion and decreasing the cost. As the power produced by a solar panel is not linearly dependent on its load, a switching power converter together with maximum power point control is essential for keeping solar panels to operate at the maximum power point [3]. A diversity of methods for maximum power point (MPP) extraction has been proposed [2]. Most methods are dependent on perturb and observational (P&O) method [1]. Although P&O is simple to execute, except it has some limitations like it fails under quickly varying environment condition and normally requires a long time to move toward the peak power point. In addition, the perturbation could cause the operation point to fluctuate around the MPP, resulting in unnecessary power wasting. To overcome these restrictions we use Incremental Conductance method [4] [7]. Solar energy monitoring and electricity generation system is a multi-power system, mainly consisting of the photo voltaic panels, battery banks, and power inverter components. Due to the distinctive nature of solar energy resource, the technique to progress the utilization of solar energy resources has long been a topic of concern [8]. The overall improvement of solar based energy system is an important method to develop the
