## Summary

Aptos Solar is a US-founded manufacturer established in 2019 by former Mission Solar engineers, headquartered in California with manufacturing based in Bac Ninh province, Vietnam. The company is not currently listed on BloombergNEF's Tier 1 list, meaning it carries less recognition among project financiers, but it markets a proprietary Dual Nano Absorber (DNA) cell technology and backs its panels with lengthy warranties, up to 25 years on product and 30 years on power output. Canadian Solar, by contrast, is a Canada-headquartered company operating since 2001 that has held BloombergNEF Tier 1 bankability status for years, with global module manufacturing capacity in the range of 50-60 GW annually, giving it a substantially stronger institutional footprint and easier access to project financing.

Aptos Solar's catalog is comparatively narrow, built around the DNA-120 and DNA-144 module families in monofacial and bifacial variants, aimed mainly at residential and smaller commercial rooftops in the US market. Canadian Solar fields a much broader lineup, including the HiKu and TOPHiKu6 series for residential and commercial and industrial (C&I) use and the TOPBiHiKu series for utility-scale ground-mount plants, most of it built on newer-generation N-type TOPCon cells reaching efficiencies above 24 percent. That breadth makes Canadian Solar the more versatile option across project sizes, while Aptos remains a smaller, quality-focused niche brand centered on residential installs.

For a typical international buyer who needs bankability for project financing or is planning a commercial or utility-scale deployment, Canadian Solar is the safer default choice given its Tier 1 status and manufacturing scale. Aptos Solar can be a reasonable option for smaller rooftop projects where warranty length and claimed low degradation matter most, but the absence of Tier 1 status means buyers should confirm financing and insurance implications with their lender before committing.
