To Study and analysis of 21 KW Solar Photovoltaic Power plant installed in Adhish industries Govindpura, Bhopal (M.P.)

Power Electronics

Solar energy is radiant light and heat from sun. Solar photovoltaic is a technology that converts sunlight into direct current by semiconductors using photovoltaic effect. Solar PV has wide applications in Industrial, social, commercial and residential sectors. Global growth of Solar PV has set an exponential growth between 1992 to 2019. The top installers are China, US and India. There are more than 24 countries around the world with a cumulative capacity of more than one Giga watt. India has huge potentials of harnessing the solar energy with 300 clear sunny days and annual temperature in the range of 25 to 27.5oC. In central India also scope for solar PV generations are high with solar potential of about 5.5 kWh/m2/day. A study relating the estimation of power generation before installation and its validation with actual generation is necessary to make this technology widespread. In this thesis, we have evaluated the performance of a 21kW solar photovoltaic power plant installed at the roof of Adhish industries situated at JK road, Govindpura Industrial area, Bhopal, (M.P.) by monitoring its actual monthly generation data and comparing it with the simulation results of predicted generation of two software BlueSol PV and Helioscope. The results obtained in all the cases indicated that the simulation results of both the software programs are not hypothetical. They have a close resemblance with the actual generation data of the site obtained after recording the generation units from inverter or generation meter. Following conclusions can be drawn from the thesis work we have performed: • The energy generation varies monthly according to temperature, climate and weather conditions. • The predicted generation data of two software programs BlueSol PV and Helioscope have a close resemblance with the actual generation data of the site and are not completely hypothetical. • The monthly variations in the actual generation of energy with prediction results of BlueSol PV are in the range of 10% to 25% with an annual variation of about 17.82%. • The monthly variations in the actual generations of energy with the predicted results of Helioscope software program are in the range of 0 to 10% for most part of the year except in the month of July and August with variations of 16.78% and 23.54% respectively probably due to uncertain raining patterns in concerned year with an annual variation of about 5.43%. • The variations in predictions results of both the software programs is in the range of 0 to 25% with most variations in the months of winter season which are November, December and January with variations of about 24.56%, 24.24% and 24.3% respectively with an annual average of about 13.1%. • The generation data predicted by the simulation results of Helioscope software program is more identical and relevant for the climatic conditions of central India. Thus the performance of this plant is satisfactory with about 80-95% of the actual power generation with respect to predicted performance of two software programs BlueSol PV and Helioscope.
