Indonesia currently has 34 domestic solar module manufacturers with combined annual production capacity of 10,944 MWp, as the government seeks to strengthen local supply chains to support its planned 100 GW solar expansion program.
The figure was presented by the Ministry of Industry at the Policy Dialogue “Target PLTS 100 GW Indonesia” in Jakarta on Wednesday (May 13).
The ministry said domestic producers are already able to manufacture solar modules with capacity of up to 720 Wp per module.
The average local content level, known locally as TKDN, for domestic solar modules currently ranges from 40 percent to 55 percent.
According to the presentation, the national solar module industry has developed with production capacity of around 11 GW per year and has supported solar power plant development in Indonesia.
The ministry said the planned 100 GW solar power program could create a major market opportunity for domestic solar module producers, particularly if supported by policies that encourage the use of locally manufactured products.
However, local manufacturers still face strong price competition from imported products, especially from China.
The presentation showed that imported solar modules are priced at around 11 US cents per Wp, while local modules are priced at around 14 to 20 US cents per Wp.

The ministry also noted that the current minimum local content threshold for solar power projects remains at 20 percent, which still allows imported solar modules to be used in projects.
To strengthen the domestic industry, the ministry proposed increasing the use of local solar modules in solar power projects, including by optimizing Tier 1 solar module producers that already have TKDN of 44.11 percent.
The ministry also proposed incentives or rewards for rooftop solar projects that use domestically produced modules.
In addition, the ministry suggested non-fiscal incentives, including larger quota allocation for projects that use local solar modules.
The presentation listed several domestic solar module producers, including PT Len Industri, PT Adyawinsa Electrical and Power, PT Surya Utama Putra, PT Sankeindo, PT Jembo Energindo, PT Sky Energy Indonesia Tbk, PT Sundaya Prima Utama, PT Delima Sakti Indo, PT Indonesia Solar Global Tbk, PT Solar Quest, PT Indodaya Surya Lestari, PT Nusa Solar Indonesia, PT Apollo Solar Indonesia, PT Trina Mas Agra Solar, SEG Solar, and PT Fajar Solar Teknologi.
The ministry also mentioned other solar module producers outside the association list, including PT IND Solar Tech, PT Atelier Solar Indonesia, and PT Lesso New Energy.
The ministry said strengthening the domestic solar module industry would be important as Indonesia prepares to expand solar deployment across industrial estates, rural electrification programs, diesel replacement projects, and other demand centers under the 100 GW solar power agenda.
Indonesia’s industrial estates alone have estimated solar power potential of 50.62 GW, consisting of 35.89 GW of rooftop solar and 14.73 GW of ground-mounted solar, according to the ministry’s presentation.
The ministry said industrial estates could become one of the main demand centers for domestic solar modules, as they host large electricity consumers and have growing demand for renewable power to support decarbonization and sustainability targets.
