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

Checking cache...

AE Solar was founded in 2003 in Germany and is one of the more established European-branded solar module manufacturers, with over two decades of industry experience, a production capacity exceeding 2 GW, and Tier 1 bankable status confirmed by BloombergNEF. This combination of longevity, scale, and bankability makes AE Solar a well-recognized name in both European and global project finance circles. VSUN, founded in 2012 and operating with a presence in Germany, is a younger and more compact brand with a catalog of 111 panels and no Tier 1 bankable designation in the available data. While VSUN has made notable inroads in adopting premium cell technologies, AE Solar's broader footprint and established track record give it a stronger position in markets where lender and financier confidence is a hard procurement requirement.

AE Solar's portfolio of 442 panels spans a wide range of applications, with a maximum module power of 730 Wp and the highest recorded efficiency reaching 24.43% - giving it flexibility for residential rooftop installs, commercial C&I projects, and large utility-scale ground-mount deployments. VSUN's narrower but more technology-focused lineup leans heavily on N-type TOPCon cells, which represent 72.1% of its catalog versus 49.8% at AE Solar. VSUN also posts a higher bifacial share (74.8% vs 63.8%), a higher average module power of 523.7 Wp compared to AE Solar's 497.0 Wp, and a marginally better average temperature coefficient for Pmax (-0.308%/°C vs -0.313%/°C). This positions VSUN well for bifacial-friendly ground-mount and commercial installations where rear-side irradiance gains are achievable.

For international buyers working on financed projects in regulated markets, AE Solar's Tier 1 status, greater production scale, and two-decade track record make it the lower-risk and more lender-friendly choice. VSUN offers a compelling technology profile - strong TOPCon penetration, high bifacial share, and above-average wattage - and suits buyers prioritizing modern cell technology and a streamlined product selection, provided that formal bankability is not a binding project constraint.
