## Summary

Aptos Solar Technology, founded in 2019 and headquartered in California with manufacturing in Vietnam, is a small, privately held company with roughly 14 employees and no formal Tier 1 bankability rating from Bloomberg NEF or comparable institutions. AIKO Solar, by contrast, was founded in 2009 in China, is publicly listed on the Shenzhen Stock Exchange, holds confirmed Tier 1 bankable status, and has been aggressively expanding manufacturing capacity - with plans exceeding 30 GW of back-contact cell and module output across multiple factories. On institutional footprint alone, AIKO carries significantly more weight: it has the balance sheet, scale, and third-party recognition that lenders and large project developers typically require.

The two portfolios diverge sharply on performance metrics. Aptos deploys 100% PERC cell technology across 33 products, averaging 431 Wp and 20.6% module efficiency, with a peak of 550 Wp and 21.3% - numbers that are respectable for PERC but solidly mid-tier by 2025 standards. Its temperature coefficient averages -0.334%/°C, and just over half its lineup (52%) is bifacial, making it a reasonable fit for cost-sensitive residential rooftops or small commercial installs where outright efficiency is secondary. AIKO, building 74% of its 144-product range on proprietary All Back Contact (ABC) cell technology, averages 581 Wp and 23.7% efficiency, peaks at 805 Wp and 25.2%, and delivers a markedly better temperature coefficient of -0.271%/°C - meaning less power loss on hot days. Only 24% of AIKO's lineup is bifacial, but the sheer output density targets premium rooftops and utility-scale ground mounts where maximizing watts per square meter justifies a higher price per panel. Both brands offer approximately 30-year warranties.

For most buyers in 2025, AIKO is the stronger default choice where budget permits: its efficiency lead, lower thermal losses, Tier 1 status, and broad product depth make it better suited to both residential premium installs and commercial or utility projects. Aptos remains a credible option for US buyers who prioritize domestic-brand optics, need bifacial panels at moderate power classes, or are working with installers already familiar with the product - but its lack of Tier 1 recognition and limited scale are genuine considerations for any project requiring long-term financial assurance.
