## Summary

I have enough sourced information now.

AU Optronics is a Taiwanese electronics company headquartered in Hsinchu, formed in 2001 from the merger of Acer Display Technology and Unipac Optoelectronics. Best known globally as a top LCD panel maker, AUO entered the green energy business in 2008 and began marketing its photovoltaic products under the BenQ Solar brand from 2012 onward, positioning it as a Tier 1 module and cell manufacturer with an integrated value chain spanning polysilicon through finished modules. HT-SAAE traces its roots to 1960, when it developed solar technology for China's satellite program, later commercializing photovoltaic manufacturing in 2000; it is recognized as a Tier 1 bankable manufacturer with a broad international footprint, including nine marketing centers across Europe, Asia, Australia and the Americas, and a Turkish production facility with roughly 2 GW of annual capacity that has shipped panels into markets worldwide. Between the two, HT-SAAE currently shows the more active and clearly documented institutional footprint, with recent capacity data and an established Tier 1 designation, while AU Optronics' solar identity is smaller and less visible today relative to its core LCD business.

AU Optronics, through the BenQ Solar line, historically targeted commercial and residential rooftop installations, leveraging the BenQ consumer brand to build trust with homeowners and small commercial buyers, alongside utility-scale deployments in Taiwan. HT-SAAE's catalog is broader and more current, spanning over a hundred module variants from 330 W to 630 W with efficiencies up to roughly 23.9 percent, built primarily on TOPCon cell technology, and serving everything from residential rooftops to large ground-mount utility projects.

For a typical buyer in 2025, HT-SAAE is the more straightforward default choice: it has an active, well-documented Tier 1 status, modern TOPCon technology, and a wide, currently produced product range with verifiable specifications. AU Optronics/BenQ Solar's solar division has a lower profile today and less recent independent data, making it harder to verify current bankability or product availability, so buyers should confirm present-day supply and support before committing.
