Longi, a Chinesesolar module manufacturer, and Pertamina New & Renewable Energy, a unit of Indonesia’s state-owned Pertamina, have initiated construction of a 1.4 GW solar cell and module factory in Deltamas, Cikarang, West Java, Indonesia. The site’s strategic location supports efficient distribution and supply chains.

Pertamina stated: “This initiative supports the Indonesian Government's commitment to fulfilling the Domestic Component Level (TKDN) and aims to meet the increasing demand for domestic solar PV modules.” Indonesia’s current solar panel production capacity is 1.6 GW per year, per the Ministry of Industry. Pertamina added: “Our new factory will increase national production capacity to 3 GW so that it can later support the government's target of 300-400 GW in 2060.”

In mid-June, Indonesia and Singapore agreed to develop a solar panel industry in the Riau Islands, establishing a green industrial zone in Karimun and Bintan to facilitate cross-border clean energy trading. In May, U.S.-based SEG Solar launched a solar cell factory in Indonesia, producing its first n-type cell, with plans to expand to 5 GW annually, covering the full solar supply chain.

The Longi-Pertamina project enhances Indonesia’s renewable energy capabilities, supporting national goals for sustainable energy and increased local production.
