- 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.
- A standalone English module warranty has been recovered, but its reviewed model table does not establish HN21RB-66HT coverage. Exact-model warranty coverage remains unresolved, so this page remains evidence rather than a score. Separately, no certification listing was found to confirm the datasheet marks for this exact model.
- This evidence record is not joined to any scored review.solar record.
- Legal manufacturer as printed: HANERSUN Energy Co., Ltd.
- The recovered English policy is marked 2026 Edition V-1.0 and applies to deliveries from 1 January 2026. Its product clause states 15 years for its covered models. The warranted-products table names HN21, HN21N, HN21RN, HN21H and HN21RH patterns; it does not name HN21RB or a BC/RB family. These adjacent model patterns do not establish entitlement for HN21RB-66HT.
- The datasheet's 15-year product and 30-year power headlines remain manufacturer summaries. A governing instrument or binding model schedule expressly covering this BC family and the applicable market is still needed before assigning commencement, output obligations, exclusions, claims, registration, transfer, remedies or labour, freight and removal costs.
- The English policy was checked on 6 October 2026 against an identical-byte same-day complete nine-page review, with the coverage table visually rechecked. This warranty-scope check does not establish local approval, sale availability, independent performance or completion of the whole product-depth review.
