INTRODUCTION Solar energy is being utilized by people from a long time. In the early time people used solar energy in the magnifying glasses to concentrate it on a single place so that its intensity used to become so much high that it could ignite the fire [1]. Photovoltaic solar electricity is one of the most distinguished techniques to generate electricity. Figure1 Block diagram of PV grid connected inverter It consists of PV plants, MPPT controller, PWM controller, power conditioner (inverter), and filter. PV plant converts the sunlight into DC power, and a power conditioning unit that converts the DC power to AC power. The generated AC power is injected into the grid and/or utilized by the local loads through the filter [2-3]. In some cases, the PV system is combined with storage devices which improve the availability of the power. The simple equivalent circuit of the PV cell model is shown in Figure. It consists of ideal current source in parallel with the diode. The practical model of PV cells consists of series resistance (Rs) and parallel resistance (Rp) as shown in figure below Figure 2 Basic equivalent circuit of PV cell The voltage current (Vg, Ig) relation of the PV plant is given in the equation below I = I ph - I 0 {exp( +ns Vt )-i}-( +Rsh ) Where V - Module voltage I - Module current I ph - Photon generated current I 0 - Dark saturation current respectively V t - Junction thermal voltage, Rs is the series cell resistance and R sh cell shunt resistance n s - Number of cells connected in series Is - saturation current, K - Boltzmann constant 1.38×10-23 J / K

Abstract – Solar energy is being utilized by people from a long time. Photovoltaic energy is one of prime source of energy due to its various edges in different domains. But growing in tandem with energy needs are the concerns about sustainable development and environmental issues, such as the movement to reduce greenhouse gas emissions. The fossil fuels and nuclear fuels are not renewable and reserves of these fuels will run out some day in the future. The exploitation of solar energy has become an essential measure to address present energy shortages and environmental problems. We have several reasons to be optimistic as there is great excitement about the possibilities opening up before scientific
community in the field of solar PV. Therefore today our main focus is to develop renewable energy especially from solar. Government of India also promoting solar energy and also providing subsidy to peoples so that pollution level means CO2 emission level decreased. In our research work photo crystalline PV solar panel is used and with help of boost converter DC level increased and this is achieved by MPPT also used PI controller to limit voltage and current. During boost phenomenon some distortion came into existence and our prime priority is to limit THD 5% as per IEEE standards. With appropriate designing, total harmonic distortion level of our work lies below 4 %. Simulation result shows that value of power factor achieved unity and THD below 5% and besides this our boost voltage is far supreme than reference voltage.
