- LONGi describes the Hi-MO 9 Prime as a back-contact module built on its HPBC 2.0 architecture, with a 132-cell layout measuring 2382 x 1134 x 30 mm.
- LONGi announced its premiere at Intersolar Europe in June 2026 for utility-scale projects, and the release gives no delivery or availability date.
- The 680 W and 25.2% figures are the maker's 'up to' headline values, not the rated value of any specific power bin.
- It cannot be scored yet: the release prints no model code, links no datasheet and names no certification, and its 12-year materials and processing warranty and 30-year linear power warranty appear only in launch copy, not in a warranty document.
- This evidence page is not joined to the scored LONGi Hi-MO 9 LR7-72HYD record.
- LONGi’s 23 June 2026 release attributes a Pmax temperature coefficient of -0.260%/°C, power tolerance of 0 to +3% and bifaciality of 75% with a +/-5 percentage-point tolerance to the Prime family. No exact power-bin electrical table, full temperature-coefficient set or numeric NOCT is established by that release.
- The release describes two 2.0 mm heat-strengthened glass layers, an anodized aluminium frame and an IP68 junction box. It claims front/rear maximum static loading of 5400/2400 Pa and a 25 mm hail test at 23 m/s. These are attributed maker claims; no exact-model certificate or independent test report has been reviewed. Junction-box IP68 does not establish whole-module waterproofing.
- The launch summary states first-year degradation below 1%, annual degradation up to 0.35% from years 2 to 30, and 88.85% output at year 30. It cites a datasheet, but that exact Prime sheet has not been recovered. The 12-year materials/processing and 30-year output headlines do not establish governing entitlement, commencement, exclusions, claims, remedies or service costs.
- The release’s energy and revenue example is manufacturer project modelling for a 10-hectare UK Midlands scenario with 50% ground coverage. It is not independent field yield or a general revenue guarantee; its headline and body give different revenue summaries. Its shading comparison also lacks a reviewed independent protocol or exact-model report.
- The current general Hi-MO 9 product page identifies LR7-72HYD with 144 cells and 635 to 660 W electrical columns. Those codes and values are not transferred to the Prime release’s 132-cell family or its up-to-680 W headline. Exact Prime identity, governing warranty, certification and local availability remain open.

LONGi's own release names the Hi-MO 9 Prime, describes its HPBC 2.0 back-contact architecture, 132-cell layout, dimensions, headline power and efficiency, launch warranty terms and utility-scale target market.
