## Summary

Gintech is a Taiwanese solar cell manufacturer founded in 2005, headquartered in Hsinchu, Taiwan. The company played a significant role in Taiwan's PV industry before merging with Neo Solar Power and Solartech in 2018 to form United Renewable Energy Co., Ltd. (UREC), which at the time became the world's fifth-largest cell maker by capacity with a combined installed capacity projected at 5 GW. The Gintech brand persists in some trade directories but operationally the entity now sits within UREC. No current standalone Bloomberg NEF Tier 1 listing for Gintech was found in available 2025-2026 sources. AIKO Energy, by contrast, is a mainland Chinese manufacturer headquartered in Guangzhou, established roughly a decade later, and achieved bankability recognition from Bloomberg in 2024, with recent trade reporting noting shipments of approximately 12 GWp of modules in H1 2025 alone - giving AIKO a considerably larger current institutional footprint.

On the product side, Gintech's legacy catalog centered on monocrystalline and PERC cells sold primarily to commercial and utility customers across Asia, with its Taiwan-based manufacturing positioning it as a premium-origin alternative to mainland Chinese volume producers. AIKO has staked its identity entirely on ABC (All Back Contact) cell architecture, a differentiated technology that relocates both electrical contacts to the rear of the cell, eliminating shading losses from front-side busbars. PV Tech and pv-magazine have confirmed AIKO's mass-production cell efficiencies consistently breaking through 27.3%, placing it at or near the top of global module efficiency rankings since 2023. Its Neostar series targets premium residential and commercial rooftops where space is constrained and maximum yield per square meter commands a price premium.

For most buyers evaluating panels in 2025-2026, AIKO is the more straightforward recommendation: it is actively shipping at scale, carries confirmed bankability status, and its ABC technology delivers industry-leading efficiency in real-world deployments. Gintech as a standalone brand is essentially a legacy designation absorbed into UREC, and prospective buyers should treat any current Gintech-branded product as a UREC product and verify that entity's current certifications independently.
