Indonesia

Scientists in Indonesia have investigated early operational defects in a 24.9 MW solar PV system in Sumatra and have identified hotspot formation as the dominant defect. They also detected 282 cases of glass cracking, 350 cases of junction box failures and shading effects linked to module defects.

The European Commission says 41 cross-border energy projects will receive €1.25 billion ($1.3 billion) in funding, with one-fifth allocated to hydrogen, while Lhyfe has started building its fifth hydrogen production site in northern France, set to provide green hydrogen by 2026.

China’s REPT Battero has revealed plans to build a lithium-ion battery plant in Indonesia, targeting 8 GWh of annual production capacity in the first phase.

Scientists have developed a multi-physics thermal model for panels with a natural convection cooling loop and tested it against experimental data. They have also experimented with varying the coolant channel thickness and different coolants. The highest measured electrical efficiency reached 15.45%.

The Jakarta-based Institute for Essential Services Reform (IESR) says 2025 will be a pivotal year for Indonesia’s energy transition, as the nation has fallen behind targets in recent years. It seeks to shift fossil fuel subsidies to renewables and is urging the government to implement a clear, measurable plan for the upcoming national energy policy.

Just a few months after beginning construction on a cell manufacturing factory in Egypt, Singapore’s EliTe Solar has opened a cell manufacturing facility in Indonesia. The Indonesian project took around eight months to complete from site selection to opening.

Wood Mackenzie predicts that the global floating solar market will be dominated by the Asia-Pacific (APAC) region and led by India, China and Indonesia through to 2033. The consultancy says growth will be driven by rising demand, decreased capital expenditure and supportive policies.

Thornova Solar has started producing solar modules in Indonesia. The company says the move is in line with changing US market regulations. It plans to supply customers with modules from Indonesia or the United States by mid-2025.

Scientists created a model to study bifacial PV thermal (BPVT) solar panels using jet impingement and built an experimental setup to validate it. They achieved a thermal efficiency of 62.28%, while electrical efficiency peaked at 11.22%.

The Institute for Essential Services Reform says Indonesia’s solar industry has faced a downturn over the past two years, but policy reforms should accelerate solar deployment in the coming years. The think tank’s latest report states that 16.92 GW of projects are currently in the pipeline across the country.
