LONGi and Pertamina have announced a solar PV manufacturing partnership in Indonesia
It entails the development of a 1.6 GW solar panel factory to serve domestic and Southeast Asian demand
The factory will contribute to the country’s TKDN policy that supports the use of domestic resources in industrial projects
Leading solar PV manufacturer LONGi has partnered with Indonesia’s state-owned energy company Pertamina to develop a 1.6 GW solar module manufacturing facility in Indonesia, based on the Chinese company’s proprietary back contact technology.
The state-of-the-art plant will use LONGi’s high-efficiency HPBC 2.0 cell technology, which incorporates the company’s TaiRay wafer, to deliver high-efficiency solar modules from its Deltamas, West Java location. Manufacturing preparations are set to begin by June 2025.
Solar modules produced at the factory will cater to both the domestic market as well as across Southeast Asia.
Pertamina is part of the venture through its subsidiary Pertamina New & Renewable Energy (Pertamina NRE), and brings its local energy market understanding to the table. It targets 6 GW of clean energy-based power plant installed capacity by 2029, including solar, increasing from around 2.6 GW it achieved by H1 2024.
According to the partners, this facility will enhance the domestic component level as required under the country’s Tingkat Komponen Dalam Negeri or TKDN policy, which requires a certain percentage of locally sourced materials, labor, and services to be used in projects, including in the space of energy facilities.
“By localizing production, we aim to drive down costs, foster innovation, and create high-value green jobs, reinforcing our commitment to a net-zero world,” said LONGi Vice President Dennis She.
LONGi’s plans follow US-based SEG Solar commissioning its maiden 2 GW solar cell production factory in Indonesia in May 2025 (see SEG Solar Launches 2 GW Solar Cell Factory In Indonesia).
These factories will support Indonesia’s target to achieve 17.1 GW of new solar PV installations in the country over the next 10 years under its Electricity Supply Business Plan (RUPTL) 2025-2034 (see Indonesia To Add 42.6 GW Renewables By 2034 Under RUPTL).
