## Summary

G-STAR is a Singapore-based manufacturer founded in 2019, operating without Tier 1 bankable certification. It offers a compact lineup of 12 panel models, with a maximum output of 595 Wp and a peak module efficiency of 23.03%, driven by TOPCon cell technology, which covers 58.3% of its portfolio. Jinko Solar, founded in 2006 and headquartered in China, is a publicly listed company on the NYSE with over 33,800 employees and a module production capacity of 130 GW. Jinko has held the top spot in BloombergNEF's PV Module Bankability Survey for 10 consecutive years and ships modules globally, maintaining the number one position in worldwide shipment volume. The two manufacturers differ sharply in scale, market history, and financial credibility, even though both lead with TOPCon as their primary cell technology.

G-STAR's portfolio stands out for its high share of bifacial modules at 58.3%, a competitive average temperature coefficient of -0.30%/°C per degree Celsius, and an average product warranty of 30 years - figures that make it a reasonable candidate for residential rooftop installs and small ground-mount systems where long-term output guarantees matter. Jinko Solar's 545-model portfolio spans a far broader power range, reaching up to 735 Wp per panel, with a top module efficiency of 24.8% and record-breaking TOPCon cell results confirmed by independent laboratories. Its Tier 1 status makes it the standard choice for utility-scale ground-mount projects and commercial C&I installations where lenders and insurers require bankable brands. Jinko's bifacial share sits at 31.9%, with average warranties of approximately 28.5 years across its wide catalog.

For international buyers choosing between the two, Jinko Solar is the lower-risk option for large-scale or bank-financed projects, given its decade-long Tier 1 track record, production scale, and global supply chain. G-STAR presents a potentially cost-effective alternative for smaller or self-financed installations where the buyer is comfortable with a newer, non-Tier-1 brand in exchange for a longer stated warranty period and a bifacial-heavy product lineup.
