| Abstract | This paper presents Energy Management for a Solar Home at the Rural Electrification Learning Center, KingMongkut's University of Technology Thonburi (Bangkuntien). The solar home comprises of power sources from asolar system, a battery system, and a transmission line system. Electricity rate is different depending on the energysource and electricity consumption period. The solar home system equipment are connected on SMA Sunny HomeManager to collect and display data via a website. Data analyses of solar home from July to December 2015 weredivided into 2 cases; a home without solar system and the solar home with energy management by Frugal discharge.It was found that, a solar home with energy management by Frugal discharge can save the electricity bill by 24,820baht per year. If the electricity is sold back to a transmission line system, a solar home with energy management byFrugal discharge can increase revenues by 12,497 baht per year. On economic analysis at interest rate of 10% peryear, a solar home with energy management by Frugal discharge has a payback period of 16 years, the NPV value isnegative, the B/C Ratio lower than 1 and the IRR of 2.96%. |
