Solar panel LONGIHi-MO X10 - LR7-54HVH - 485Wp - Back Contact

LONGi Hi-MO X10 LR7-54HVH 485 module Wp – Back Contact HPBC 2.0

23.8% efficiency, Back Contact HPBC 2.0 technology, PPE2 certified: the LONGi LR7-54HVH 485 Wp , the reference module for common residential and commercial projects.

Back Contact HPBC 2.0: the technological foundation of the Hi-MO X10 range

The LR7-54HVH 485 Wp It is based on the same technological platform as the entire Hi-MO X10 range: Back Contact HPBC 2.0 architecture, electrical contacts entirely repositioned on the rear panel, and a maximized front active area. The result: a 23.76% STC efficiency on the LR7-54HVH-485M, without the front-panel busbars that generate resistive and thermal losses in standard architectures.

Performance data — LR7-54HVH-485M:

• Module yield: 23.76% in STC — above the standard TOPCon threshold for this format

• STC power: 485 Wp / NOCT: 369 W — Vmp 33.40 V / Imp 14.53 A

• Power tolerance: 0 ~ +3% — guaranteed delivery at or above nominal level

• Dégradation première année : < 1 %, puis 0,35 %/an de l'année 2 à 30 — 88,85 % résiduel à 30 ans

• Maximum temperature coefficient Pmax: -0.260 %/°C

• System voltage: DC 1500 V (IEC) — fully compatible with Huawei, Sungrow, Fronius, SMA, and SolarEdge string inverters

• Low carbon certification PPE2/PPE2 V2 (modules after January 2025) — eligibility for CRE4 tenders

This module is available in variant 490 Wp — LONGi Hi-MO LR7-54HVH 490 Wp Back Contact .

Mechanical characteristics and field durability

The 485 Wp shares the same mechanical format as the entire LR7-54HVH range — a decisive advantage for installers who are streamlining their stock and installation systems.

• Dimensions : 1800 × 1134 × 30 mm — standard residential size, compatible with all Mounting systems certified professionals listed on POwR Certifications

• Weight : 21.6 kg — identical to the 490 Wp same construction site logistics

• 3.2 mm coated tempered glass — RG4 certified (hailstones 40 mm at 27.54 m/s), internally validated up to 45 mm

• Static load, front face: 5400 Pa / rear face: 2400 Pa

• IP68 junction box, 3 diodes — hotspot protection, partial shade management via cell

• Double POE encapsulation — enhanced sealing, resistance to moisture degradation

• Hybrid Passivation - Partial shading management per cell for optimized production

• Anodized aluminum frame, black finish, white background — high-end residential roof integration

• Front face without visible busbar — with no visible metallization grid on the front, the module's surface is uniform and homogeneous, unlike TOPCon modules where the silver lines remain visible. On roofs exposed to Facade or visible from the street, it's a selling point that the end customer immediately perceives

Professional application areas

Standard and semi-premium residential

The LR7-54HVH 485 Wp is the volume choice for installers active in the single-family residential market. It delivers Back Contact HPBC 2.0 technology on sites where the available surface area is adequate—roofs of 25 to 60 m² facing south or southwest—without the price increase of the 490 Wp Its 23.76% efficiency remains significantly higher than a standard TOPCon or PERC module in this format, with the same 25/30-year warranties. For an installer structuring a competitively priced offer with premium technology, this is the right selling point.

Tertiary and C&I up to 250 kWp

The 1500V system voltage, efficient temperature coefficient, and PPE2 certification make the 485 Wp A module directly usable on commercial and industrial projects. On a rooftop Trapezoidal sheet metal With a surface area of ​​500 m², the 1800 × 1134 mm format optimizes the number of modules per row. The low-carbon PPE2 V2 certification simplifies compliance documentation for public and semi-public project owners.

FAQ — LONGi LR7-54HVH 485 Wp Back Contact

Is the 485 Wp eligible for CRE4 tenders and PPE2 certification?
Yes, for modules manufactured after January 2025. The PPE2 and PPE2 V2 low-carbon certification is active on the LR7-54HVH modules delivered by POwR Connect in this configuration. Certification documentation is available upon request.

What is the warranty period and what exactly does it cover?
Two warranty levels: 25 years on the product (materials and treatment, via the LONGi partner warranty extension) and 30 years on linear output power, with 88.85% of residual power guaranteed at the end of the 30 years. The annual contractual degradation is 0.35% from year 2 to year 30.

Is the module compatible with my current Mounting systems ?
The LR7-54HVH 485 Wp It measures 1800 × 1134 × 30 mm with an anodized aluminum frame. The ranges Dome Solar ( Fibro Solar RB Solar, Helios RC3, NPA), ISY-PV (slate, tile, fiber cement), K2 Systems, Shape and ET System available on POwR Connect are certified with this module.

Can the LONGi 485 Wp be mixed with other modules in the same installation?
Technically possible on separate MPPTs. On the same MPPT or string, mixing modules of different power levels degrades the overall efficiency: the string is limited by the least efficient module. POwR Connect supplies homogeneous batches to ensure the consistency of your strings.
