G-STAR vs AEET - solar panel manufacturer comparison
G-STAR has the broader catalog (36 vs 5 models). G-STAR leads on peak efficiency at 23.51%. G-STAR leans bifacial (86% of lineup).
Both catalogues are read from the manufacturers' own datasheets. A brand is not scored against the market here, only against the other brand on this page.

Catalogue against catalogue
An average over a catalogue describes the range a manufacturer publishes, not the module you would buy. A brand with two flagship panels and eighty older ones averages worse than one that has retired its back catalogue.

Written summary
G-STAR Pte. Ltd. is a Singapore-headquartered manufacturer founded in 2019, with a vertically integrated production footprint spanning Thailand, Indonesia, Laos, the Philippines, and Egypt; the company has announced total nameplate capacity approaching 17.5 GW, with roughly 3 GW of that concentrated in Southeast Asia. AEET Energy Group GmbH, based in Bad Gandersheim, Germany, operates primarily as a photovoltaic wholesale distributor and installer rather than a direct manufacturer, partnering with third-party module makers to supply and service residential and small commercial systems across Germany through a network of over 500 certified partners. Neither company holds Tier 1 bankable status under BloombergNEF criteria, which require independently financed utility-scale project references above 10 MW, but G-STAR's larger production scale and its 2024 ranking on the Global Top 500 New Energy Enterprises list give it a measurably stronger institutional footprint.
The two portfolios reflect fundamentally different product generations and target markets. G-STAR's 12-panel lineup centers on n-type TOPCon cells, delivering an average module power of 517.5 Wp and average efficiency of 22.27%, with the top model reaching 595 Wp at 23.03% - numbers that sit comfortably within the premium segment. About 58% of G-STAR's catalog is bifacial, a feature that adds meaningful energy yield on ground mounts or high-albedo rooftops, and the company backs its modules with a 30-year linear power warranty and a temperature coefficient of -0.30%/degrees C. AEET's five-panel range is considerably more modest: average output of 190 Wp, average efficiency of 14.9%, a maximum of 200 Wp at 15.7%, no bifacial options, and a 25-year warranty. The unknown cell technology designation and low power density suggest an older or budget-tier monofacial format suited to small off-grid, RV, or entry-level residential installations where cost per watt and panel count are prioritized over peak performance.
For a buyer in 2025 evaluating a rooftop or commercial ground-mount system, G-STAR is the stronger default: its TOPCon efficiency, bifacial share, and 30-year warranty align with what bankable EPCs and residential installers now consider baseline quality. AEET's portfolio still has a niche - compact, lower-power panels can suit space-abundant off-grid scenarios or simple backup systems where 200 Wp modules are easier to handle - but for anyone seeking to maximize generation on limited roof area or to attract project financing, the G-STAR lineup is the more future-proof choice.
