IMARC Group, a leading global market research and management consulting firm, has published its latest market intelligence report on the Indonesia Solar Energy Market. The Indonesia solar energy market size was valued at 598.9 GWh in 2025 and is projected to reach 1,711.6 GWh by 2034, exhibiting a CAGR of 12.38% during 2026-2034. Growth is being driven by government policies and incentives, declining solar technology costs, rising electricity demand and growing private investment.

Solar is moving from a small niche to a national priority in Indonesia. Installed solar capacity passed 1 GW in 2025 and reached 1.49 GW at the end of the year, with an estimated 546 MW added during 2025, according to the Ministry of Energy and Mineral Resources as reported by pv magazine. In August 2025 the government unveiled a plan for 100 GW of solar, including 80 GW of distributed systems in village cooperatives, and rooftop demand is already strong, with the 2026 rooftop quota of 485 MW fully used by April 2026. Domestic manufacturing is also taking shape, with new module plants from LONGi and Pertamina NRE and from PT Trina Mas Agra Indonesia announced in 2025. Even so, the IESR notes that the 100 GW plan remains under development and building it in five years would be very challenging, so execution will shape how fast the market grows.

Indonesia Solar Energy Market at a Glance:

• Market Size (2025): 598.9 GWh

Indonesia Solar Energy Market Trends and Drivers:

Policy support is the foundation. The report cites government policies and incentives, including an early-2024 amendment to Ministerial Regulation No. 26/2021 that removed the previous limit on PV installation for household PLN capacity, alongside the national push for energy self-sufficiency.

The second driver is cost and demand. Declining solar technology and equipment costs, rising electricity demand, with per-capita consumption reportedly up nearly 13 percent in 2023, and growing private investment are making solar more attractive for utilities, businesses and households.

A third driver is local manufacturing and rooftop adoption. New module factories and a strong rooftop pipeline support growth, even as regulatory hurdles, limited grid infrastructure and high upfront costs remain challenges, and renewables reached 15.75 percent of the energy mix in 2025, below the revised 17 to 19 percent target.

Government Schemes and Policy Initiatives Driving Demand:

• 100 GW Distributed Solar Program: Unveiled in August 2025 as the distributed solar for energy self-sufficiency program, it targets 80 GW of distributed solar with battery storage in 80,000 villages managed by Merah Putih village cooperatives, plus 20 GW of centralized solar, and is still under development.
• National Energy Policy 2025-2060: The policy targets up to 108.7 GW of solar by 2060, against IESR’s estimate of solar potential of 3,300 GW to 20,000 GW.
• Rooftop Solar Quota: PLN opened a 485 MW rooftop solar quota for 2026, which was fully used by April 2026, with authorities preparing up to 500 MW more and a government target of 2 GW of rooftop solar by 2028.
• Ministerial Regulation No. 26/2021 Amendment: The early-2024 amendment removed the previous PV installation limit for household PLN capacity, supporting rooftop adoption.
