- Hanersun's datasheet badges this full black bifacial module HBC and lists its cell type as back contact (BC), with 108 cells in a 1800 x 1134 x 30 mm frame.
- This record covers the Full Black HN18RB-54HTB and its 470-495 W datasheet bins. The separately listed transparent sibling HN18RB-54HT is not joined to it. The maker's download catalogue now supplies standalone warranty documents, but their model scope does not establish coverage for this BC family. This review establishes no launch date, price, stock or local approval.
- The datasheet contradicts itself on warranty: its graphic shows a 30 year product warranty, while a footnote says 15 years product and 30 years linear power under Munich Re insurance, so neither figure is assumed here.
- Standalone English and Australian warranty policies have been recovered, but neither reviewed model list names HN18RB-54HTB or a BC/RB family. Exact-model warranty coverage remains unresolved, so no product-duration figure is assigned and this page remains evidence rather than a score. Also, no certification listing has been sourced for this exact model; the datasheet's logos do not establish an exact-model certification join.
- The 24.3% figure applies only to the top 495 W bin; the lower bins in the range are rated from 23.0%.
- Legal manufacturer as printed: HANERSUN Energy Co., Ltd.
- The English policy is marked 2026 Edition V-1.0 and applies to deliveries from 1 January 2026. Its product clause states 15 years, but its listed PERC, TOPCon and HJT model patterns do not name this BC family. The Australian download policy is marked 2025 Edition, with both V-1.0 and V-2.0 printed on the cover, applies to deliveries from 1 March 2025 and states 25 years for its listed products. Neither term is transferred to HN18RB-54HTB.
- The exact datasheet's 30-year product graphic still conflicts with its 15-year insurance footnote. Its separate 30-year power illustration shows 99% after year one, annual loss of 0.35% thereafter and 88.85% at year 30; that illustration does not resolve the governing model scope or establish claims, remedies, labour, freight, registration or insurance entitlement for this product. A current instrument expressly naming this family and its applicable market is still needed.
- The warranty policies and exact sheet were reviewed on 6 October 2026. All nine pages of the scanned English policy and all ten pages of the Australian policy were read. This is a warranty-scope review; it does not confirm current sale availability, regulatory approval, insurer backing or a whole-product depth assessment.

The maker's datasheet prints the model code, the HBC badge and BC cell type, the 470 to 495 W bins with their efficiencies, the dimensions, both warranty statements and the legal manufacturer name.
- Hanersun download page, HItouch 5B sectionhttps://www.hanersun.com/download/
