Power Generation and Carbon Credit Earning by Solar Energy Systems

Abstract

This paper presents a detailed analysis of power generation through renewable energy sources and the carbon credit potential of various solar energy systems installed at the Dr. Mahalingam College of Engineering and Technology (MCET), Pollachi. It consists of a solar greenhouse, solar street lights, solar pumps, and solar photovoltaic power-generating systems. Energy generation and cost savings were achieved for these systems. Carbon credit computation was performed according to the Kyoto Protocol under local climatic conditions. The total power produced by the solar PV systems was found to be 147.456 MWh, and the total cost of power generated by these systems was found to be Rs. 12,97,613/- ($15540). The total annual carbon mitigation produced by the four standalone solar photovoltaic (SPAV) systems was found to be 137.42 tons, and the carbon credit earned estimated to be Rs. 5,84,432/- ($7008.41), whereas the annual carbon mitigation achieved through the solar greenhouse was found to be 198 tons. The annual carbon credits earned by the solar greenhouse were found to be Rs. 8.42,072/- ($10098), and the annual carbon credits earned by all the solar systems were found to be Rs. 14,26,504/- ($17106.41). The main objective of this research paper is to showcase the potential of solar systems for power generation and thermal heating applications, in addition to the benefits of CO₂ mitigation. This highlights how solar systems can be developed and promoted to meet the energy requirements and environmental sustainability of every institution. The promotion of this type of clean and renewable energy source will help save the environment from the harmful effects of fossil fuels, in addition to meeting the energy requirements.
