While the trends show the declining costs of solar PV, the annual capacity addition in solar PV development in Indonesia has been plummeting from
around 11 MW in 2015 to 916 kW in 2018. The average installation costs for residential rooftop solar PV have been stagnant for the last three years at
around IDR 18 million/kWp. Meanwhile, the average off-grid installation costs of off-grid solar PV have dropped significantly from around IDR 330
million/kWp in 2014 to IDR 98 million/kWp in 2017. The costs of off-grid installation depend on the logistic and battery costs. Most solar PV in Indonesia is
ground-mounted type and used for off-grid rural electrification (around 54%).
