Indonesia PV Module Market: The 100 GW Solar Opportunity

Indonesia is rapidly becoming one of the world’s most promising solar markets. With a revised National Energy Master Plan and a landmark 100 GW village-level programme launched in 2025, the country has set ambitious targets that far exceed its current installed capacity. At the end of 2025, cumulative grid-connected solar reached just 1.49 GW, while over 8 GW of new capacity was added during the year – a growth of more than 300 percent compared to 2023. This explosive momentum, backed by strong policy support and active participation from Chinese manufacturers, makes Indonesia a critical market for photovoltaic module suppliers and project developers.

Ambitious Installation Targets

The Indonesian government has significantly raised its solar ambitions. The latest revision of the National Energy Master Plan increased the 2030 installation target from 29.3 GW to 45 GW. In August 2025, the President launched the “One Million Village-Level Cooperative PV Programme”, which aims to construct 100 GW of PV projects within five years – 80 GW of distributed systems and 20 GW of centralised plants – with a long-term goal of 300 GW by 2050. Indonesia’s theoretical solar potential stands at 207 GW, making it one of the largest untapped solar markets in the world.

Strong Growth Momentum

The market is already showing explosive growth. By the end of 2025, the country’s cumulative grid-connected PV capacity had reached 1.49 GW, with approximately 546 MW added in that year alone. More importantly, annual PV installations exceeded 8 GW in 2025, representing a year-on-year increase of over 300 percent from 2023. Finished photovoltaic product exports from Indonesia jumped from 2.95 GW in 2024 to 11 GW in 2025, while China’s exports of solar cells to Indonesia are projected to soar by 413 percent in 2025, making Indonesia the second-largest importer of Chinese solar cells.

Strong Policy Support

The government has introduced the Renewable Energy Investment Acceleration Act, which provides support in tax incentives, land policies, and approval processes. Starting from 2026, all new solar power plants must use modules with a conversion efficiency of no less than 22 percent, which is driving demand for high-efficiency products. In addition, the government plans to prioritise the implementation of 13 GW of installed capacity as the first phase of its project pipeline.

Significant Involvement of Chinese Enterprises

Chinese manufacturers are playing a leading role in Indonesia’s solar expansion. LONGi and JinkoSolar, together with local Indonesian partners, are building Southeast Asia’s first GW-scale photovoltaic module manufacturing industrial park, which is expected to start operations in 2026 with an annual capacity of 3 GW. Hengdian Dongmag has already brought 3.8 GW of cell production capacity online in Indonesia, with shipments expected to exceed 3.5 GW in 2025. Indonesia has also absorbed a portion of overseas capacity relocation, and finished PV product exports from the country reached 11 GW in 2025, up sharply from 2.95 GW in 2024.

Market Challenges and Risks
 

Despite the bright outlook, there are notable challenges. As the world’s largest archipelago with over 17,000 islands, Indonesia suffers from weak power grids and high logistics costs, making distributed solar the mainstream direction while implementation remains difficult. Certification is another major barrier. PV modules must obtain SNI certification before they can be sold, a process that takes six to twelve months and costs up to 100,000 US dollars per model. Local content (TKDN) requirements also need to be met, which in the long term calls for establishing local manufacturing facilities. Investment costs are higher than the global average, with PV projects including energy storage ranging from 1.2 to 1.8 US dollars per watt, and local manufacturing costs are approximately 25 to 30 percent higher than in China.

Market Opportunity Analysis
 

The majority of the 80 GW distributed target consists of residential and commercial-industrial solutions, which are well suited to Chinese enterprises. Poor grid stability drives strong demand for energy storage, making integrated PV plus storage solutions more competitive. Remote islands with urgent electricity needs present a vast market for off-grid microgrid systems. The time window is especially favourable between 2026 and 2027, when policy incentives take effect and drive strong demand for EPC projects and module supply. After 2028, local manufacturing requirements will increase, so companies that establish a presence early will gain a first-mover advantage.

Strategic Recommendations

In the short term, suppliers should capitalise on the policy window to rapidly capture market share through module exports and EPC projects. For the medium to long term, localised production should be considered to meet TKDN requirements, including establishing manufacturing bases for modules and solar cells. Technical adaptation is also crucial – developing specialised modules tailored to Indonesia’s high-temperature, high-humidity environment while meeting the 22 percent plus conversion efficiency requirement will be a key differentiator. Finally, forming strategic partnerships with local Indonesian enterprises and village-level cooperatives can help mitigate policy risks.

Conclusion

The prospects for the Indonesian PV module market are exceptionally promising. The 100 GW installation target, combined with explosive recent growth and unprecedented policy support, creates a vast market opportunity. Although current installed capacity remains modest at only 1.49 GW, the potential for expansion is immense. Chinese enterprises have a significant advantage in this market due to their technological edge and cost competitiveness, but they must overcome challenges such as certification barriers and infrastructure constraints. For those who act now, Indonesia offers one of the most exciting solar frontiers in the world.
