China’s LONGi Green Technology Co. Ltd, in partnership with Indonesia’s PT Pertamina NRE (PNRE), aims to start commercial operations of its photovoltaic (PV) solar module assembly plant in Cikarang, West Java, in early 2026. The plant’s initial production capacity will be 1.5 GWh.
Andi Herlambang, LONGi Solar’s Indonesia representative, said that production testing is planned for late 2025 before the plant begins full commercial operations at the start of 2026.
“The plant infrastructure is already in place. Currently, we are waiting for the production machinery to arrive, which is scheduled to be in Indonesia around September. Installation will likely take about two months, followed by production testing at the end of the year. Our commercial production target is early 2026, but sales in Indonesia require an SNI certification, so we expect to start marketing the products domestically in the first quarter of 2026,” Andi told Petromindo.com last weekend.
He added that the company has secured a supply agreement for PV modules to be used in a power plant project developed by Vanda RE in the Riau Islands. The electricity generated from this plant will be exported to Singapore.

“So far, there is a commitment with Vanda RE for around 1 GWh. Several other agreements are still in negotiation. In the future, production capacity can be increased according to demand,” he said, declining to provide further details.
Previously, the two companies announced plans to expand assembly capacity by building a larger facility in Batang, Central Java, between 2027 and 2030.
Currently, both LONGi and Pertamina NRE remain focused on PV module assembly. However, they see potential to manufacture solar cells and other components on a larger scale in the future.
This solar manufacturing initiative aligns with growing demand in the Indonesian market for domestically produced PV modules, which is a requirement to meet the local content regulation (TKDN) in power plant projects.
