Performance Analysis of Standalone Photovoltaic System using PVSYST

Abstract

Electricity has become one of the essential needs of today’s life like food and shelter. The entire technology and advancements are completely dependent on the power which should not be interrupted at any cost. The entire world is completely damaged and polluted to the core due to the smoke, Radiations, etc., These damages create various environmental and Health issues out of which many of the problems cannot be addressed at all. So, we are in an urgent need of creating pollution free energy for an environmental-friendly scenario. Because of these requirements, many renewable energies have come into Utilization.

            Renewable Energy are the inexhaustible energy given by the nature. The different renewable energies are Solar, Wind, Hydroelectric, Ocean, Geothermal, Biomass and Hydrogen. Solar and wind energy have been leading energy producers compared to all others. Wind Energy production involves a very high Installation cost as compared to Solar Energy. So solar energy production has become more common. In India, the development of solar energy production has been rapid in the last few years. The country has total installation capacity of 44.3MW as on 31^st August 2021 with an investment of US $100 Billion. India has been ranked as five among the countries in solar energy production all over the world. Karnataka, Telangana, Rajasthan, Andhra Pradesh and Gujarat are the states which have more production of photovoltaic energy.

            Out of many Renewable Energy Sources, Solar Energy Production has become very competitive. The different types of Photovoltaic System mainly include Grid Connected System, Standalone system and the Hybrid system. Many software like PVsyst, PVSOL, HOMER Pro, SOLARGIS, System Advisor Model (SAM), Solar Pro have emerged in the recent days which enables us for designing a Photo voltaic system, Energy Production, Energy Consumption, Energy Utilizations, Analysis of Cost, etc., for any specific application. The above said analysis can be made on Hourly basis, Monthly Basis, Component-wise, etc., This work focuses on simulation of Stand-alone Photovoltaic System with PVsyst Software (PVsyst 7.2) on a small geographical location at Madipakkam, Chennai in Tamil Nādu, India. PVSyst is a software which assists us in designing and analyzing various Photovoltaic systems like Grid connected, Stand Alone and pumping applications. The project can be simulated with detailed hourly consumption and economic valuation. Meteo Databases and Component Databases listed by the manufacturers can also be utilized.

            This paper analysis on 100Wp Standalone Si-Poly Photovoltaic System. The simulated system consists of 72 cells, 7 strings of 1 module each. The entire data sets of radiation and temperature has been taken from Metronome 8.0. The energy consumption has been considered for 89.9KWh/month. The Battery used is Lead Acid with 80% DOD and battery voltage of 24V. The Performance Ratio and the Normalized Productions for different months of the year has been studied. The different losses linked with the Stand-alone plant has been studied and the feasibility of the System has been Predicted for different parameters. The detailed component wise loss diagram has also been given by reducing which the efficiency of the entire system can be increased.
