## Summary

Hiwatt Solar is a Chinese photovoltaic manufacturer with a reported annual production capacity of approximately 2.2 GW. The company produces a range of crystalline silicon modules including large-format 210 mm cell panels rated above 670 W, bifacial variants, and half-cut cell formats certified to IEC 61215 and IEC 61730 standards. No confirmed BloombergNEF Tier 1 listing for Hiwatt was found in publicly available industry sources, and the brand carries a relatively low profile in major trade publications. AIKO, by contrast, is a Chinese manufacturer founded around 2009 with production facilities spanning multiple gigafactories across Guangdong, Foshan, Zhuhai, Jinan, and other Chinese hubs, plus an R&D centre in Freiburg, Germany. AIKO achieved BloombergNEF Tier 1 status as of Q3 2024 and, as of early 2025, operates at roughly 20 GW of annual production capacity. On institutional footprint and verified bankability, AIKO holds a considerably stronger position.

AIKO has built its market identity around a proprietary All Back Contact (ABC) cell architecture, branded under the Neostar product family. ABC technology relocates all electrical contacts to the rear of the cell, eliminating front-side shading losses; independent reviewers and Taiyangnews efficiency rankings confirm mass-production module efficiencies in the 22.5-24% range, with cell-level records above 27%. The panels are positioned as a premium choice for space-constrained residential rooftops and high-performance commercial installations where power density justifies the higher upfront price. Hiwatt's catalog covers a broader mix of conventional mono and poly bifacial formats, suggesting an orientation toward volume supply in commercial and utility segments without a differentiated cell technology story.

For most buyers in 2025, AIKO is the more defensible default - it offers documented efficiency leadership, a confirmed bankability track record, a strong installer community in key markets, and a 30-year performance warranty with low degradation. Hiwatt may serve cost-sensitive procurement where Tier 1 status is not a lender requirement, but independent field data remains sparse, making it a higher-risk choice for financed projects.
