The Longi Solar Hi-MO X10 Guardian (Anti-Glare) LR7-54HVH 480~500M series is designed for locations where not only energy yield matters, but also the surrounding comfort and safety. The key difference is the Anti-Glare surface - a special textured glass structure that minimizes local glare spots, making the installation more suitable near roads, airports, residential neighborhoods, and public facilities.

In practice, this means less risk of complaints about reflections and greater design freedom, without compromising efficiency. The manufacturer emphasizes high transparency of the front layer, which helps maintain light power and absorption comparable to conventional modules. Additionally, the solution is non-coated and dust-resistant, supporting stable performance and minimizing uneven soiling issues over the long term.

This is an excellent choice for demanding rooftops and commercial installations where non-glare aesthetics, predictable energy yields, and long-term durability in real operating conditions are crucial.

What owners get
Unique Anti-Glare surface

Textured glass that reduces localized glare is a feature none of the comparable peers offer (Silfab SIL HM, Gokin GK-3-54HGF, Selfa SV120M.2.4). This is a genuine advantage for projects near roads, airports, and residential areas, where standard modules carry real risk of glare complaints.

23.5-24.5% efficiency at segment-leading level

Built on N-type BC (back contact) cells, the module reaches efficiency on par with the strongest peer (Gokin GK-3-54HGF, 24.5%) and clearly higher than Selfa SV120M.2.4 (22.6%) and Silfab SIL HM (21%), all at the same 500 Wp maximum power.

Low degradation and positive power tolerance

Degradation is 1% in year one and 0.35% per year in years 2-30, combined with a 0/+3% power tolerance (no negative values), resulting in a predictable, high energy yield throughout the 30-year power warranty period.

Bankable Tier-1 manufacturer

Longi Solar, founded in 2000, is one of the world's largest module manufacturers, which eases commercial project financing and increases confidence that warranty claims will be honored over the full 30-year term.

Coating-free design, resistant to dust

The absence of an additional anti-reflective coating on top of the glass reduces uneven soiling buildup, supporting more stable module performance over the long term, particularly on commercial rooftops.

Trade-offs
15-year product warranty trails the segment leaders

Standard product warranties for premium N-type panels in 2025-2026 already span 15-25 years, with market leaders (including LONGi's own other series) offering 25 years. This series' 15-year product warranty sits at the lower end of the premium segment.

No bifacial variant

The series is monofacial only, so it cannot capture the extra rear-side yield available from a growing number of premium bifacial modules - a real limitation for ground-mount, carport, or high-albedo installations.

Common questions

6 answered
What is the Anti-Glare surface on the LONGi Hi-MO X10 Guardian, and what installations is it designed for?
The Anti-Glare glass features a specially engineered textured front surface that diffuses reflected sunlight and reduces localized glare intensity. It is particularly suited for installations near roads, airports, residential neighborhoods, and public buildings where conventional panels could cause disruptive reflections. The solution gives system designers greater siting flexibility without requiring additional environmental or planning approvals related to light nuisance.
What is the maximum power output and efficiency of the LONGi LR7-54HVH 480~500M Guardian?
The module delivers up to 500 Wp peak power and up to 24.5% module efficiency, placing it among the top-performing monofacial N-type panels on the market. High efficiency translates to less roof area required to reach a given system capacity — a critical advantage on rooftops with limited mounting space.
Does the Anti-Glare surface reduce the power output of the LONGi Hi-MO X10 Guardian compared to the standard Hi-MO X10?
Not significantly. LONGi specifies front glass transmittance of at least 93.8%, which is comparable to standard solar glass. The textured surface scatters reflected light without meaningfully reducing light absorption. The rated power of the Guardian Anti-Glare series is effectively equivalent to standard Hi-MO X10 variants with the same cell configuration.
How does the LONGi Hi-MO X10 Guardian LR7-54HVH perform in summer heat and high operating temperatures?
The N-type HPBC 2.0 cell technology delivers a favorable temperature coefficient of Pmax at -0.26%/°C, meaning the module loses relatively little power as cell temperature rises above 25°C — noticeably better than older PERC modules. In practice, installations on highly irradiated rooftops or in warm climates will maintain a significantly higher energy yield during summer peak hours.
What warranties are included with the LONGi Hi-MO X10 Guardian LR7-54HVH 480~500M series?
LONGi provides a 15-year product warranty covering materials and workmanship, plus a 30-year linear power warranty guaranteeing at least 88.85% of rated output at end of life. As a Tier 1 manufacturer, LONGi's long-term financial stability supports reliable warranty service throughout the full operational lifetime of the installation.
Can the LONGi LR7-54HVH 480~500M Guardian be installed on a standard pitched roof?
Yes. At 1800×1134×30 mm and 21.6 kg, the module is compatible with standard racking systems using aluminum rails with mid and end clamps. As a monofacial (single-glass) module, it does not require a minimum rear air gap for bifacial albedo gain, making integration on typical residential or commercial pitched roofs straightforward.
