Abstract
This paper discusses the recent solar rooftop PV system policies in Indonesia, particularly for the implementation of the residential sector. The aim of this study is to demonstrate the rooftop PV system for a household based on the current related policies. The study is conducted by literature reviews and computer simulation for a typical rooftop PV system for residential in Surabaya, Indonesia. The most recent solar energy policy in Indonesia is the Ministry of Energy and Mineral Resources (MEMR) Regulation No. 49, the year 2018, which establishes net metering for the residential, commercial and industrial National Grid (PLN) customers that have excess power from solar rooftop installations. The simulation shows the average values global solar irradiation on a horizontal surface in Surabaya vary between 6.81 kWh/m2 and 4.82 kWh/m2 with an average of 5.54 kWh/m2 per day. Energy output by 3 kWp rooftop PV system in Surabaya is found about 4,200 kWh per year, with an average of 11.67 kWh/day. Economically, under present conditions, rooftop on-grid PV system investment would give about 9-10 years of the payback period.Keywords: Rooftop, PV System, Solar Energy, Residential, IndonesiaJEL Classifications: C58, G18, H41,H50 & Z18DOI: https://doi.org/10.32479/ijeep.9539
Highlights
Solar energy is one of the most promising of renewable energies in attempting to reduce fossil-based fuel consumption due to its limited reserved and the greenhouses gas (GHG) emissions from the combustion process
The objective of this study is to demonstrate the rooftop PV system for households based on the current related policies and to figure out the opportunity benefits from the user’s perspective
The calculation is based on the energy used value minus energy produced by the rooftop PV system value
Summary
Solar energy is one of the most promising of renewable energies in attempting to reduce fossil-based fuel consumption due to its limited reserved and the greenhouses gas (GHG) emissions from the combustion process. By the time of writing this paper, based on various sources (Hamdi, 2019; Tarigan, 2018; Tarigan et al, 2015), it is estimated that there are approximately 14.7 MW of solar PV system running on-grid, 48 MW under construction, and an estimated 326 MW in the pipeline. This capacity is relatively small in comparing to the neighboring South East
