QSun Solar vs AEET - solar panel manufacturer comparison
AEET has the broader catalog (5 vs 0 models).
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.
The two companies
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
I have enough research to write the comparison now.
QSun Solar is a China-based photovoltaic module manufacturer founded around 2014, with production facilities in Anhui and Jiangsu provinces and a claimed annual output in the multi-gigawatt range. AEET is a far smaller and less documented brand with no verifiable headquarters details, founding year, or production-capacity figures surfacing in industry sources. Neither manufacturer appears on the BloombergNEF Tier 1 list, meaning neither has demonstrated the financial track record needed to support non-recourse project financing - an important consideration for commercial developers and institutional investors. Between the two, QSun Solar carries the noticeably stronger institutional footprint, with ISO 9001, 14001, and 45001 certifications and a broader international distribution presence.
The portfolio differences are substantial. QSun Solar's 20-panel lineup is built entirely on PERC cell technology, averaging 482 Wp per module and peaking at 670 Wp, with an average efficiency of 19.9 percent and a maximum of 21.6 percent. That combination - competitive efficiency, high power density, and a low average temperature coefficient of -0.3695 percent per degree Celsius - makes QSun a reasonable fit for residential rooftops and mid-scale commercial installations where roof space is limited. AEET's five-panel lineup, by contrast, tops out at 200 Wp and 15.7 percent efficiency, with an average of 190 Wp and 14.9 percent; its cell technology is listed as unknown. Those figures are consistent with older polycrystalline or entry-level monocrystalline formats, and they suit compact off-grid applications such as marine, RV, or small rural systems rather than grid-tied rooftop projects. Both brands offer 25-year warranties and carry no bifacial options.
For a typical buyer planning a grid-tied residential or small commercial installation in 2025, QSun Solar is the clearer choice: its PERC panels deliver meaningfully higher efficiency and power output per module, which reduces balance-of-system costs. AEET's low-wattage range fills a specific niche for size-constrained or portable off-grid setups, and the two brands are not genuinely interchangeable for the same application.
