Abstract

This work studies the technical, economic, and environmental of a 3 kWp rooftop photovoltaic (PV) system for residential in Surabaya, Indonesia. The studies were conducted based on the data from a built instalation of rooftop on-grid PV system. In addition, analysis were carried out using SolarGIS PV planner, RETSCreen, and PVsyst simulation tools. The results show that a 3 kWp rooftop system in Surabaya could produce electricity of about 3,898 kWh per year. Under present conditions, economic analysis shows that the rooftop PV system investment would give the payback period of about 5 years. Environmentally, the 3 kWp PV system would result of the reduction of greenhouse gas (GHG) emission of about 3.8 tons of CO2 per year.

Highlights

The Indonesian Government under the Ministry of Energy and Mineral Resources (MEMR) has recently set a target of 23% of renewable energy to replace fossil-based energy to fulfill the total national energy demand by 2025[1]

The aim of this study is to evaluate a rooftop on-grid PV system, for a typical residential building in Surabaya, Indonesia

Summary

Introduction

The Indonesian Government under the Ministry of Energy and Mineral Resources (MEMR) has recently set a target of 23% of renewable energy to replace fossil-based energy to fulfill the total national energy demand by 2025[1]. From various of available renewable energy resources, solar power is one of the most promising of renewable energies, for Indonesia which is benefitting its position around the equator line. In this connection, the photovoltaic (PV) rooftop system regulation [2] has recently been introduced to encourage users, including residents, public, and commercial buildings roofs to generate electricity using PV. Every geographical position has different potential and characteristics of solar energy. Redweik et al (2013) [3]developed a solar three-dimension (3D) urban model to calculate the solar energy potential on the roof and facades of a building in urban areas. Limited studies have been reported about rooftops with on-grid PV system in Indonesia [2], [8], [9]
