THE VALUE OF INVESTMENT ON RENEWABLE ENERGY: A CASE STUDY OF POWER GENERATION BY SOLAR ENERGY ROOF SYSTEM PROJECTED BY HOMEPRO, MEGA HOME AND MARKET VILLAGE

Abstract

The objective of this study is to study the value of investment on the project producing electric power by installing solar energy roof systems by HomePro, Mega Home, and Market Village. The data were collected by 25 branches of HomePro, Mega Home, and Market Village, which voluntary joined “Power Generation by Solar Energy Roof System Project”. The data were analyzed by using net present value (NPV) internal rate of return (IRR) and Payback Period. The results show that from the first project investment, the investment was of 616,114,000 baht, net present value (NPV) was of 82,201,288 baht, internal rate of return (IRR) was of 6.69% and payback period was of 11.55 years. For the second project, it investment on 409,303,000 bath, NPV was as of 199,882,718, Internal rate of return as off 10.94% and payback period as of 8.19 years. The study shows that the value of investment on the project producing electric power by installing solar energy roof systems by HomePro, Mega Home, and Market Village is worth. In addition, it can also help reduce greenhouse gases influencing negatively ecological environment. At the end, it can reflect on the corporate social responsibility in using renewable energy instead of using fossil fuel.
