Across the world, the cost of solar panels is declining, and Indonesia is no different. The price of solar modules dropped from USD 4.12 per watt in 2008 to USD 0.17 per watt in 2020. This translates to lower costs for solar energy, which are around USD 0.04 per kWh.
On the other hand, most regions in Indonesia are exposed to sunlight throughout the year without exception. Therefore, the solar energy potential in Indonesia is as high as 6 kWh/m 2 /day . This advantageous condition has allowed the solar photovoltaic (PV) system to solve the issue mentioned earlier.
The economic aspect of solar energy, particularly the cost of solar panels, plays a critical role in its adoption. This price reduction is crucial for the decarbonisation of Indonesia's energy sector and signifies solar power's role in the global climate transition.
Additionally, the Indonesian government recently hinted at new private-sector partnerships to build solar panel manufacturing facilities and boost the country's quartz and silica sand production – two of the core raw materials for solar panels.
