Indonesia Solar Energy Market Analysis

The Indonesia Solar Energy Market is expected to grow from 2.15 gigawatt in 2025 to 2.97 gigawatt in 2026 and is forecast to reach 14.91 gigawatt by 2031 at 38.10% CAGR over 2026-2031.

Jakarta’s pivot from diesel subsidies toward grid-scale and distributed photovoltaic systems, the 5.746 GW rooftop quota framework, and PLN’s commitment to 17.1 GW of solar capacity in its RUPTL 2025-2034 blueprint, together underpin this growth trajectory, signaling a decisive reallocation of capital away from coal baseload. Module average selling prices fell nearly 50% during 2024, shipping costs normalized, and Indonesian EPC bidders routinely met PLN’s ceiling tariff of IDR 1,200 per kWh, which pushed the Indonesian solar energy market below grid-parity levels in high-irradiance provinces. Corporate renewable-power purchase agreements (RE-PPAs) surged as RE100 manufacturers in Java and Batam locked in twenty-year rooftop contracts that guarantee Scope 2 abatement and long-term price certainty. Utility-scale developers attracted by the archipelago’s 207 GW technical potential, the USD 20 billion JETP commitment, and regulatory clarity under Presidential Regulation 112/2022 are queueing projects in Java, Sumatra, and Sulawesi despite grid-absorption quotas and foreign-exchange risks.

Indonesia Solar Energy Market Trends and Insights

Government Rooftop Incentives Accelerate Distributed Adoption

MEMR Regulation 2/2024 ended net-metering and replaced it with a 5.746 GW quota, clarifying interconnection rules and protecting PLN revenues while sustaining tax allowances for commercial systems. Jakarta’s Governor Regulation 38/2024 now obliges the installation of rooftop solar on new commercial buildings exceeding 500 m², a mandate mirrored in West Java and Bali. Together with the quota, this delivers a transparent pipeline that boosts developer visibility until 2028. The mechanism caps excess-generation credits, steering households toward self-consumption yet unlocking larger corporate installations that can absorb daytime output. Developers have accelerated engineering timelines to secure quota allocations early, anticipating tighter windows once the residential segment restarts in 2027. At the same time, municipal fines and permitting incentives ensure higher compliance, thereby expanding the Indonesian solar energy market in densely populated urban districts.

Module ASP Declines Compress Levelized Costs Below Grid Parity

Polysilicon spot prices declined from USD 30/kg in 2023 to USD 8/kg by Q4 2024, halving crystalline-silicon module ASPs and enabling EPC bids as low as IDR 1,050 per kWh in recent PLN tenders. Normalized freight rates shaved another 15-20% off landed costs for Chinese Tier-1 modules, pushing levelized electricity costs beneath coal benchmarks in East Nusa Tenggara and South Kalimantan. Developers responded by lodging unsolicited PPA proposals that already exceed PLN’s 17.1 GW solar allocation for 2025-2034. Yet margin pressure remains as manufacturers offload high-priced inventory, compelling Indonesian firms to hedge order timing. Forward curves indicate that if Chinese factory utilization stays above 600 GW annually, the Indonesian solar energy market will benefit from sub-USD 0.07 kWh tariffs through 2026.

TKDN Local-Content Mandate Elevates Project Economics

MEMR Decree 191/2024 trimmed the TKDN threshold to 20%, yet developers still face 12-18% higher EPC costs because Indonesia lacks polysilicon and wafer plants, leaving PT Len Industri’s 600 MW line as the chief compliant source. Queue times stretch to nine months, compelling utility-scale sponsors to renegotiate PPA schedules or accept partial-import penalties. PLN remains reluctant to uplift tariffs, forcing margin compression that cascades through the supply chain. Several IPPs now bundle balance-of-system gear from domestic suppliers to surpass the 20% threshold, although audits can delay commercial-operation certificates by up to 90 days. Unless new gigawatt-scale factories reach commercial operation before 2027, the TKDN rule will continue to hinder the Indonesian solar energy market.

Other drivers and restraints analyzed in the detailed report include:

  1. RE100 Corporate Commitments Drive C&I PPA Volume
  2. Diesel Displacement in Eastern Archipelago Eases Fiscal Strain
  3. Grid-Absorption Constraints Trigger Curtailment Incidents

Segment Analysis

Solar PV accounted for 100.00% of the Indonesian solar energy market size in 2025 and is forecast to advance at a 38.10% CAGR through 2031. CSP remains commercially unviable because most Indonesian sites record 1,400-1,600 kWh/m² DNI, which is well below the 2,000 kWh/m² threshold that CSP needs to remain competitive. PV capex of USD 800-1,200 kW undercuts CSP’s USD 4,000-6,000 kW, so investors concentrate capital on crystalline-silicon routes. Bifacial and TOPCon modules captured 60% of 2024 imports as developers chase 10-15% yield gains in land-constrained Java. Compliance with IEC 61215 and IEC 61730 standards upholds bankability despite price compression, further reinforcing PV’s exclusive status in the Indonesian solar energy market.

Second-generation cell technologies accelerate yield improvements, mitigating curtailment risks by enabling lower nameplate sizing for fixed quotas. LONGi and Trina each delivered over 500 MW of bifacial shipments in 2024, primarily for floating PV and hybrid diesel sites. As module energy density rises, developers forecast a 7% drop in land requirements by 2027, alleviating community-acceptance barriers in peri-urban Java while bolstering project IRRs.

How Do Licenses Work?

How Do Licenses Work?

The primary function of a report license is to define how many people within a company are authorized to use the purchased report. This is separate to how a report might be delivered. Unless specifically identified otherwise, the purchase option is Single User. Below is a helpful description of that license, along with a sampling of others most commonly offered.

  • This license allows only one user to have access to and to use/read the report. It is not one user at a time or one user group; it is an individual who will be reading and utilizing the report.

  • This license allows for the entire purchasing company to read and use the report. This is the license level that would allow for a report to be placed on an internal company shared drive for access by all employees of that direct company. This license does not extend to parent or sister company use.

  • This license is designed to allow an entire department within a company full access to a report. The departmental license is a great option for companies that have more than one location and the department is spread out all over the country/world

  • This license is for companies that have one location where they want the report to be accessible by all employees within that physical location.

  • This is the most flexible of the licensing options. Some publishers will allow you to get a license for a preset number of people (typically 5). These licenses are ideal for small work groups.

License options are at the discretion of each publisher. As such, not all licenses indicated above are available for every product. If you are uncertain of the best license for your needs or would like a license that is not proactively available, please contact us and we will be happy to assist.
