การศึกษาความเป็นไปได้ของการจัดตั้งโครงการผลิตพลังงานไฟฟ้าจากแสงอาทิตย์ กรณีศึกษา จังหวัดตรัง

Abstract

The objective of this research was to evaluate a feasibility of establishing a Solar Photovoltaic power plant using sunlight to generate electricity. The result is used as a guideline for entrepreneur and government sector to make investment decisions and will be an example for other studies. Four major aspects were analyzed: marketing, technical, legal & requirement, and economics. The results indicate that the production of electricity is 7,008,000 units per year and will be decreased by an average of 0.7% per year. All the electric will be sold to Provincial Electricity Authority (PEA) for 25 years. The solar photovoltaic cell,solar inverter and other equipment are the technology from China. The investment cost is approximately 264 million baht with owner capital. With respect to the legal and requirements, the photovoltaic power plant is not illegal. Regarding economics analysis, the result indicates that with minimum attractive rate of return at 10, Net Present Value is 34,619,537 baht, Internal Rate of Return is 11.79% and Pay-Back Period is 7 years 7 months. It could be concluded that it is rational to invest in the Solar Photovoltaic power plant for the project.
