- 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.
- The only official sources found are this datasheet and Hanersun's download page, which also lists a separate transparent back sibling (HN18RB-54HT) that is not joined to this record; neither source gives a launch date, price or market availability.
- 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.
- It cannot be scored yet because there is no standalone warranty document to settle those terms and no certification listing has been sourced; the datasheet shows certificate logos only.
- 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.
