Written summary
G-STAR is a solar PV manufacturer headquartered in Singapore, founded in 2019. It operates production in Southeast Asia, including a 1.5 GW cell and 1 GW module facility in Subic Bay, the Philippines - launched in 2025 - alongside earlier capacity in Thailand and a planned U.S. presence. The company was ranked among the 2024 Global Top 500 New Energy Enterprises but does not appear on published BloombergNEF Tier 1 lists, which is a meaningful gap for project finance contexts. Hyundai Energy Solutions, by contrast, is a subsidiary of the South Korean Hyundai conglomerate and carries BloombergNEF Tier 1 status, giving it considerably stronger institutional and bankability credentials. Between the two, Hyundai holds the deeper market footprint with lenders and large-scale developers.
On product mix, G-STAR spans PERC, TOPCon, and HJT technologies across both monofacial and bifacial formats, with power outputs from roughly 425 W to 595 W. Its n-type bifacial modules launched in the Philippines in 2025 are certified by ETL, UL, CE, and TUV. The company's Singapore and Southeast Asia origin also exempts its modules from the U.S. Section 301 tariffs that apply to Chinese-origin goods, which gives it a pricing edge in the American market. Hyundai Energy Solutions focuses primarily on the residential and small commercial segments, with product families including the XG Series, YH bifacial line, and higher-efficiency NF Series, the last of which reaches efficiencies confirmed at over 22% using n-type TOPCon and shingled cell technology. Hyundai backs its modules with a 25-year product and performance warranty.
For a typical buyer in 2025 or 2026, Hyundai is the safer default where bankability or long-term service infrastructure matters, such as financed residential rooftops or commercial systems requiring insurable warranties. G-STAR is worth considering for cost-sensitive projects in the U.S. market where tariff relief is a priority and the buyer is comfortable with a newer, less-established brand name.
