In August 2025, the global photovoltaic industry witnessed a wave of intensive capacity expansion across Southeast and South Asia.
U.S.-founded SEG Solar commenced Phase I of its large-scale PV industrial park in Indonesia; Insolation Energy expanded production in India with a 3 GW module factory; Premier Energies launched a 1.2 GW TOPCon production line. These moves reflect the dynamism of the regional market.
SEG Solar Commissions 2 GW Cell Factory in Indonesia, Signs Exclusive Cooperation Agreement
On August 8, SEG Solar announced the commissioning of Phase I of its large-scale PV industrial park in Indonesia and signed an exclusive cooperation agreement with local company PT ATW Modul Manufaktur (AMM).
The SEG Solar Batang Photovoltaic Industrial Park represents a total investment of over $500 million and covers 101.14 acres. The Phase I project, with a capacity of 2 GW, has completed its first shipment of solar cells and achieved stable production capabilities.
On the same day, SEG Solar and AMM signed an exclusive distribution agreement. Under the agreement, AMM will exclusively distribute SEG Solar-branded solar modules and cells in Indonesia. Leveraging SEG Solar’s N-type cell technology and localized production capabilities, the two parties will jointly serve Indonesia’s utility-scale projects and cross-border projects requiring TKDN certification. As of the end of 2024, SEG Solar had shipped over 6 GW of modules globally, with a production capacity of 6 GW.
Insolation Energy Expands in India: 3 GW Module Factory Launched
On August 21, Insolation Green Energy, a subsidiary of India’s Insolation Energy, announced the official commissioning of its 3 GW PV module factory in Rajasthan.
India’s PV industry faces significant external dependencies: modules are heavily reliant on imports, with local production accounting for less than 30% of the market. Upstream polysilicon and wafers are almost entirely imported, midstream cell capacity is insufficient, and while downstream module manufacturing has a foundation, it depends on imported core equipment. Insolation Energy’s expansion plan targets these supply chain gaps.
In addition to the newly commissioned 3 GW module factory, the company unveiled a more ambitious integrated blueprint: plans to build a full industrial chain capacity of “8 GW modules + 3 GW cells + 54,000 tons of aluminum frames,” covering everything from raw materials to end products. This aims to eliminate dependence on external supply chains. Insolation Energy’s expansion is emblematic of Indian PV manufacturers seeking breakthroughs.
Premier Energies Commissions 1.2 GW TOPCon Cell Production Line
Premier Energies, one of India’s largest integrated solar manufacturers, recently announced two key developments: its 1.2 GW N-type G12R solar cell production line has officially begun commercial operation, and it has simultaneously launched 620W DCR high-efficiency modules based on TOPCon technology. This move positions the company among India’s first cohort of manufacturers mastering large-format N-type technology.
The newly launched G12R modules are India’s first large-format rectangular N-type products, designed for utility-scale power plants and commercial & industrial rooftop applications, among other scenarios.
The Indian government’s Domestic Content Requirement (DCR) policy encourages projects to use locally produced PV products, creating a favorable environment for domestic manufacturers like Premier Energies. In recent years, Premier Energies has expanded rapidly and now ranks among the top three PV manufacturers in India, as well as being one of the largest domestic solar cell producers.
The commissioning of this 1.2 GW TOPCon production line not only continues its technology leadership strategy but also drives the transformation of India’s PV industry from “scale expansion” to “quality and efficiency improvement,” bolstering the country’s competitiveness in the global PV technology landscape.
