Solar Electric Power Generator (SEPG) as a solution for peak load in household sector as energy conservation system: A case study in Pekanbaru City of Indonesia

摘要

The Solar Electric Power Generator (SEPG) has been designed having capacity of 320 Watt peak (Wp) and storage capacity 600 ampere-hour (AH) or equivalent with 7,200 Watt-hour (Wh) aimed for a substitution of peak load in a household sector. Modul and energy storage were designed to apply directly in certain period during a day time. Experiments have been done on an open circuit to examine the SEPG, which given a maximum and output voltage is 19.58 VDC and 18.01 VDC respectively. On the other hand the experiment with load test with battery bank given 18.29 VDC, otherwise regulator output voltage during bank battery charging is 13.8 VDC. Based on the simulation which has been done for the household sector having connecting power of 900VA supplied by the Government Electric Board with average peak load consumption of 1,300 Wh, it is proved approximately of 67.9 percent could be substituted by SEPG.
