This research reviews power quality problems that raises by changes in weather conditions like solar radiations and the variation in the load connected with the system. These power quality problems like voltage fluctuation, voltage distortion, and harmonics at the L.T. line are generated by source and load also at the PCC. This paper comprises about power quality problems and mitigation technique on the by using active filters. Age of fossil fuel as source of energy is constantly getting extinct. Demand of fuel and energy is exponentially rising with time. At the same time energy cost is also continuously increasing. To overcome these critical situations we can use renewable resources at our disposal from which energy can be tapped. Photovoltaic cell converts solar energy to direct electric energy.
