Abstract

The purpose of the present study is to demonstrate the concept of peak-suppression by energy saving and replacement of peak load by solar PV energy supply to replace nuclear power. An office with 150m2 floor area and 14 employees was chosen as the demonstration site. The results show that retrofit for energy-saving reduces 65% energy and the solar PV system supplies 20%. The total energy reduction is 85%. The total investment of the solar PV system and the retrofit of energy-saving devices is around USD30,000. The net total energy saving in 20 years is USD 80,000, including M&O cost. The system has been run about one year. The measured average total power consumption of the office is reduced from 10.2 kW to 3.6 kW (after retrofit) in which solar PV supplies about half.
