Techno-economic analysis of rooftop solar power plant implementation and policy on mosques: an Indonesian case study

Abstract

Indonesia is pushing the implementation of renewable energy to meet its climate action target. Solar energy is abundant, and its utilization is prioritized, including rooftop solar power plant (RSPP). This research presents a techno-economic analysis of an RSPP installed in a mosque in Ngombol subdistrict, Purworejo district, Central Java, Indonesia. This article also introduces and explains the regulation of RSPP and electricity tariffs in Indonesia, which define the economics of RSPP. This study employs an operational and financial model to analyze RSPP in five scenarios. The RSPP design objective is to reduce the annual energy usage of the mosque and yield the highest Net Present Value (NPV). According to the result, RSPP at all configurations based on the type and number of panels yield negative NPVs at the current electricity tariff, costs of components, and regulations implemented concerning RSPP. Proposed policy adjustment modeled through different scenarios provide benefit to some extent, limited by other policies. Hence, a combination of different policy adjustments may be required to achieve the most optimal condition for RSPP implementation on the mosque rooftop. This study could help policymakers to understand the possible directions of policy design for faster PV implementation.

The solar end game: bibliometric analysis, research and development evolution, and patent activity of hybrid photovoltaic/thermal—phase change material

“…Extending from the city to university campus in Iraq, solar energy cost for PV grid-connected system was 6.3¢/kWh with NPV value at 551,600US$ (Ali and Alomar 2023 ). Suparwoko and Qamar ( 2022 ) have conducted an evaluation pertaining to the economic value of solar PV system installed on the rooftop of the mosque at the Central Java, Indonesia. Five difference case study was deployed to identify the feasibility of rooftop solar PV technology implementation based on current/possible situation in Indonesia.…”

Pengaruh Ketebalan Lapisan Film Tipis TiO2 Nanopartikel terhadap Sifat Optik dan Listrik Sel Surya Perovskite CH3NH3PbI3

“…Indonesia memiliki potensi energi terbarukan dengan total kapasitas sebesar 417,6 GW dari berbagai sumber seperti panas bumi, angin, air, dan energi matahari. Sayangnya, tingkat pemanfaatan dari energi terbarukan tersebut masih rendah, karena sektor energi di Indonesia masih didominasi oleh bahan bakar fosil (Suparwoko & Qamar, 2022). Penggunaan bahan bakar fosil ini akan menyebabkan tingginya emisi gas yang menyebabkan pemanasan global (Slameršak dkk., 2022).…”

Solar power plant on the rooftop of the Diponegoro University Rectorate: a technical and economic study

“…Meanwhile, the weakness of this system is its inability to transmit electrical energy to the load while experiencing a power outage from the power grid because the inverter will automatically turn off when there is no incoming voltage from the power grid [17], [18]. The electric power generated from the solar power plant during a power outage will be lost if there is no storage battery in the solar power plant [17], [19]. This causes considerable energy losses and will result in an increase in the payback period (PP) for solar power plants [8], [13], [17], [19].…”

This causes considerable energy losses and will result in an increase in the payback period (PP) for solar power plants [8], [13], [17], [19]. The purposes of this study are to compare the configuration of solar panels and inverters and find out which configuration will give the best results and provide the biggest savings.…”
