LONGi 650W Hi-MO 9 HPBC Double Glass Silver Frame Solar Panel

The LONGi Hi-MO 9 650 W is a Back-contact (BC) cell on an N-type TaiRay wafer solar panel. It delivers 24.1 % module efficiency from a 2,382 × 1,134 mm frame.

About the LONGi Hi-MO 9 range

Hi-MO 9 is LONGi's large-format utility and commercial module, pairing the back-contact cell with double-glass construction for high-output ground mount and commercial rooftop arrays.

At 2,382 mm tall and 2.70 m² this is a commercial-format module, intended for warehouse and barn roofs, ground mounts and solar farms where the extra length is not a constraint. It is usually too long for a typical domestic roof plane.

Why installers specify this panel

  • Hail tested to 25 mm at 23 m/s — relevant for exposed and upland UK sites.
  • Long-dated warranty — 12-year warranty for materials and processing and a 30-year linear power output warranty; first-year degradation under 1 %, 0.35 % per year from year 2 to 30.

Warranty and certification

12-year warranty for materials and processing and a 30-year linear power output warranty; first-year degradation under 1 %, 0.35 % per year from year 2 to 30. Certified to IEC 61215, IEC 61730, UL 61730, ISO 9001:2015, ISO 14001:2015, ISO 45001:2018 and IEC 62941.

Array sizing

Each panel covers 2.70 m². A 4 kWp array needs 6 of them (3.90 kWp over about 16 m²). A 6 kWp array needs 9 of them (5.85 kWp over about 24 m²). At 32.7 kg each they are a two-person lift.

About LONGi

LONGi is one of the largest solar manufacturers in the world and the company behind the Hi-MO series. Its HPBC back-contact platform is the successor to the PERC modules it shipped in volume for a decade, and it is manufactured to IEC 61215 and IEC 61730 under ISO 9001, ISO 14001, ISO 45001 and IEC 62941 quality systems.

Datasheets, installation manuals and warranty documents for the LONGi Hi-MO 9 are in the Documents tab below. Buying for a project? Contact our sales team at sales@clearraysolar.com for pallet pricing.

Due to size of the panels and size of the gap between the slats of the pallets (both length and width entries) a fork lift truck on site is required to offload these modules.
