Singapore-headquartered solar PV manufacturer Gstar Solar has taken a significant step forward in the development of its 3GW photovoltaic manufacturing facility in Indonesia with the shipment of critical equipment. The delivery, which includes monocrystalline growth furnaces and control systems, marks the start of the key installation phase for the plant, which will produce 3GW of monocrystalline silicon rods and 3GW of silicon wafers annually.
The monocrystalline growth furnaces, employing the Czochralski (CZ) crystal growth method, are equipped with fully automated control systems to precisely manage temperature, pulling speed, and rotation during the crystal growth process. This ensures high-quality silicon with low dislocation densities, meeting industry standards for photovoltaic production, the company said on Friday.
Gstar plans to install a total of 120 furnaces at the facility in stages. The plant will focus on producing large-size silicon wafers, including 182mm and 210mm formats, which support the growing demand for larger and more efficient photovoltaic products.

The plant is set to commence trial production in May 2025, with full production capacity expected to be achieved shortly thereafter
Located in the Greenland International Industrial Center (GIIC) in Kota Deltamas, Cikarang, West Java, the plant benefits from its strategic location within one of Indonesia's most rapidly expanding industrial hubs. This area is home to numerous multinational corporations, creating a robust ecosystem for Gstar’s operations and future expansions.
Gstar’s regional network also includes operational factories in Thailand and Laos, while a module factory in the Philippines is in the final stages of commissioning.
