- Hanersun's datasheet describes the HItouch 6B as a bifacial module using back contact (BC) cells, with 132 cells and bins from 645 W to 670 W at up to 24.8% efficiency.
- Hanersun showed it at Intersolar South America in August 2026 as a BC module for the distributed market, and that release gives no sales or availability date.
- That release quotes 680 W, which is above the 670 W top bin on the only published datasheet, so 680 W is not a rated value for HN21RB-66HT.
- It cannot be scored yet: the datasheet only summarises a 15 year product and 30 year power warranty with no full warranty terms, and no certification listing was found to confirm the marks shown on the datasheet.
- This evidence record is not joined to any scored review.solar record.
- Legal manufacturer as printed: HANERSUN Energy Co., Ltd.
