ROOFTOP SOLAR PV Sluggish development despite huge solar energy potential SOLAR RESOURCE MAP PHOTOVOLTAIC POWER POTENTIAL INDONESIA 100 E Medan 0° Padang Palembang 10°S 2017 THE WORLD BANK WORLD BANK GROUP THE WORLD BANK IFC ESMAP 110°E 120°E 130°E Ternate 140°E SOLARGIS 10°S 200 km . Indonesia has huge solar energy potential, counting for more than 500 GW and the largest compared to other renewables resources the country has. IRENA estimated that Indonesia could develop up to 3.1 GW of solar energy per year from 2016 to 2030 and attain 47 GW of solar capacity in 2030 which is sufficient to meet RUEN target. By the end of 2017, only 90 MW of solar energy had been installed. • Although incorporated in RUEN as one of strategies to develop solar power, rooftop solar PV remains to play small role in the Indonesian power sector. • By June 2018, Indonesia had only installed 521 kWp of residential, 5 kWp of social, and 1080 kWp of industrial rooftop solar PV (PPLSA, 2018). In terms of technology costs, Indonesia has comparable LCOE to neighbouring countries, at USD 0.06 -0.11 per kWh compared to Thailand at USD 0.07 0.12 per kWh (Mott MacDonald, 2017) Balikpapan Jayapura Banjarmasin Ambon Makassar Jakarta Surabaya Solar resource data: Solargis Long term average of PVOUT, period from 2007 (1999 in the West) to 2016 Daily totals: 3.0 3.4 3.8 4.2 4.6 kWh/kWp Yearly totals: 1095 1241 1387 1534 1680 This map is published by the World Bank Group, funded by ESMAP, and prepared by Solargia.
