This paper presents a modeling and analysis of the levelized cost of electricity (LCoE) related to solar Photovoltaic (PV) power plants. As the PV matures, the economic feasibility of PV projects is increasingly being evaluated using the LCoE. Regulation of the Minister of Energy and Mineral Resources of the Republic of Indonesia Number 19 the Year 2016 concerning the purchase of electricity from PV Power Plants by PT PLN (Persero) for On-Grid PV in East Nusa Tenggara with a purchase of 0.23 US$ / kWh, but the purchase price of electricity for Off-Grid PV system have not been determined. The aim of this study was to analyze LCoE for PV systems so that could help policymakers and PV investors to calculate the cost of providing PV systems for rural areas, especially in Kupang Regency. The research method uses an LCoE modeling approach. The results showed that LCoE PV On-Grid system at the level of 0.19-0.21 US$/kWh, and LPoE at the level of 0.21-0.23 US$/kWh. LCoE Off-Grid PV system at the level of 0.29-0.31 US$/kWh, and LPoE at the level of 0.31-0.33 US$/kW. The result from modeling PV On-Grid System, estimated by 2030, LPoE at the maximum level of 0.24 US$/kWh.
This paper analyzes the impact of the snail trails and cracks phenomena in 200 Wp photovoltaic (PV) modules to energy output after five years of operation. Data collection was carried out through string voltage measurement, visual inspection, and Real Operating Conditions (ROC) test for permanently degraded PV especially the type of snail trail and crack degradation conducted at the Lotas Off-Grid PV System, South Central Timor Indonesia. For this paper, we applied quantitative methods to analyze data. The result shows that the permanent degradation caused by the snail trail will experience a maximum power decrease of 67 Watt per m 2 , while permanent degradation caused by crack will experience a power decrease of 551 Watt/m 2 .
Rasio elektrifikasi di Kabupaten Kupang masih 60%. Rata-rata rumah tangga yang belum mendapatkan pasokan listrik berada di perdesaan terpencil yang sulit dijangkau oleh jaringan PLN. Alternatif yang paling baik dalam penyediaan sumber energi listrik di perdesaan Kabupaten Kupang yang belum terjangkau oleh jaringan PLN adalah menggunakan modul PV. Tujuan penelitian ini adalah untuk membandingkan efisiensi modul PV bahan monocrystalline dengan polycrystalline dan menemukan model estimasi karakteristik modul PV pada saat musim kemarau. Metode yang digunakan dalam penelitian ini adalah metode observasi yaitu melakukan pengukuran variabel SR, S, ISC dan VOC. Hasil penelitian menunjukkan bahwa modul PV monocrystalline lebih efisien dibandingkan dengan modul PV polycrystalline. Pada penggunaan modul PV monocrystalline, model estimasi persamaan regresi adalah Isc = 0.0009 SR + 1.9497 dan Voc = 28.02 - 0.2683 S. Pada penggunaan modul PV polycrystalline model estimasi persamaan regresi adalah Isc = 0.001 SR + 1.6649 dan Voc = 25.644 - 0.2196 S.
