Abstract
The sun is the main source of energy that provides light and heat energy. By the advancements in the power electronic components, grid tied solar PV System is readily available for distributed generation to meet the energy requirements of the customers. The objective of this study and analysis is to predict the potential for solar PV system and solar thermal energy exploration and the potential for mitigating CO2 emissions and economic benefit. A case study is carried out at Shimoga Milk Union Limited (SHIMUL) Dairy, Machanahalli, Shimoga, Karnataka, India, handles 90 lakh litre of milk, consumes 2,03,524 units of electricity and 1350 tonnes of steam per month. Analysis has been made on integration of 600 kW solar PV system with grid and solar water heaters with necessary infrastructure for supplying electrical and thermal energy. The study yields the result that, Solar PV System produces 60,000 units per month reduces 29.5% of electrical energy import from grid and 50 evacuated tube flat plate collector type solar water heaters of 1000-litre capacity to supply the 50,000 litres of hot water to the boiler at 65˚C reduces input of fuel by 23%, reduces the annual reduction of CO2 emission by 1626 tonnes. Return on Investment for solar pv system and solar thermal system is 5 years and 2.7 years, respectively. The analysis extended for each of the various fuels typically used in boilers to produce steam.
