Abstract: Abstract This study presents a financial analysis of a rooftop solar project for industry and considers other benefits including carbon trading possibilities. It suggests exchanging renewable energy certificates that could both bring additional values to the project and be supporting the energy transition process of Vietnam. This research utilizes a financial calculation tool named Rooftop Solar Toolkit for Industrial Energy Users by CEIA in cooperation with Apparel Impact Institute (AII) and Sustainable Trade Initiative (IDH). CEIA Toolkit is used to evaluate solar power installation projects, helping users compare different investment options and which option is the most profitable to the investors. As a finding, installing rooftop solar power, regardless of investment option, brings more financial benefit to the company than buying electricity from the national grid. Using 70% of loan is the best option in terms of NPV. Emission reduction can be up to 155 tCO2/year during the system’s lifetime. In addition, applying for the Renewable Energy Certificates or joining the carbon trading market further increase the profits for the project investors, not to mention other values such as increasing company’s social responsibility and branding.
