**Top-tier efficiency for the segment** - Efficiency of up to 23.39% places the series above flagship bifacial N-type competitors such as Trina Solar Vertex N (23.2%), DMEGC DMxxxG12T-B66HSW (23.2%), and AE Solar METEOR CME-132 (23.21%), all at the same 720 Wp maximum power. - **Low HJT temperature coefficient** - Heterojunction (HJT) cell technology delivers a Pmax temperature coefficient of around -0.26%/°C versus the typical -0.35% to -0.40%/°C for PERC modules, translating into meaningfully higher yield during hot Polish summers. - **30-year linear power warranty** - The manufacturer guarantees power retention over a full 30-year period, with a guaranteed end-of-warranty value of roughly 89-93% Pmax, well above the industry-standard 25-year / ~84.8% offered by many Tier-1 competitors. - **Glass-glass construction limits degradation** - Dual-glass construction instead of a polymer backsheet significantly reduces the risk of microcracks, cell corrosion and PID, combined with the low LID typical of N-type cells for a more stable energy output over the module's lifetime. - **Extra yield from bifacial gain** - Active harvesting of ground-reflected irradiance delivers additional energy output, particularly in ground-mount installations over bright albedo surfaces, shortening the payback period compared with equivalent monofacial modules. ## Cons - **No BNEF Tier 1 status** - Unlike comparable series from Trina Solar Vertex N or DMEGC DMxxxG12T-B66HSW, Luxor Solar does not appear on BloombergNEF's Tier 1 bankable manufacturer list, which can complicate financing for commercial projects that require this criterion. - **Smaller production scale than market leaders** - Founded in 2007, Luxor Solar is a mid-sized manufacturer compared with giants like Trina Solar (in the market since 1997, with tens of GW of annual output), raising questions about the ability to honor 30-year warranty commitments over such a long horizon. ## About this series The Luxor Solar Eco Line N-Type HJT Glass-Glass Bifacial series is an advanced solution based on **heterojunction technology (HJT)**, which effectively combines the advantages of crystalline and thin-film silicon. Thanks to this approach, these modules achieve above-average efficiency even in low light conditions and feature one of the lowest temperature coefficients in the entire industry. The durable **glass-glass** construction ensures extreme resistance to external factors, eliminating the destructive risk of micro-cracks and chemical corrosion. The use of **N-Type** cells in combination with **bifaciality (Bifacial)** allows for the active generation of additional energy from light reflected off the ground, which realistically shortens the return on investment time. These panels effectively solve the problem of premature power degradation, offering a linear performance warranty at a level unheard of among standard manufacturers. This product is dedicated to conscious investors and businesses seeking uncompromising system longevity in the variable Polish climate. What distinguishes this series from the competition is primarily the **negligible LID and PID effect**, which translates into stable power yields for over thirty years of operation. By choosing these modules, you gain the assurance of fire safety and the highest operating standard of the entire photovoltaic installation. ## Notable figures - At 22.9% efficiency, this panel is on par with typical \*\*HJT 700-750W\*\* modules - 226.9 W/m² power density is 3.2 W/m² below \*\*HJT 700-750W\*\* median (230.2 W/m²) - requires larger installation area - Temperature coefficient of -0.24%/°C matches the \*\*HJT 700-750W\*\* median - 85% bifaciality enables rear-side power generation, boosting yield by 4-13% on reflective surfaces - Ranked #2359 out of 14005 panels for efficiency in the database ## Questions ### What warranty does the Luxor Solar Eco Line N-Type HJT Glass-Glass Bifacial series come with? The Luxor Solar Eco Line N-Type HJT Glass-Glass Bifacial series includes an exceptional 30-year product warranty and a 30-year linear power output warranty. This means the manufacturer guarantees a defined minimum performance level for a full three decades of operation — well above the 12–15 years typical of budget suppliers. For investors calculating LCOE and payback period, this extended coverage is a significant financial advantage. ### Do the Luxor Eco Line HJT Glass-Glass panels perform well in winter and overcast conditions? Yes. HJT technology delivers one of the industry's lowest temperature coefficients, measured at just -0.24%/°C for the 700–720W models. In practice, output drops minimally during summer heat, while on cooler, overcast days the amorphous silicon interlayers maintain above-average efficiency under diffuse irradiance — conditions that are common throughout the year in Central Europe. ### What does bifacial design offer in the Luxor Eco Line HJT panels and how much extra energy can be generated? With a bifaciality factor of up to 95%, the rear side of the panel captures irradiance reflected from the ground, rooftop surface, or snow. Depending on the albedo of the substrate, this can translate to 5–25% additional annual energy yield compared to a standard monofacial module. With a peak rating of 720Wp on the front side alone, the effective system output is further boosted by rear-side gain, shortening the overall investment payback period. ### Why are the Luxor Eco Line HJT Glass-Glass panels more resistant to microcracks and corrosion than conventional modules? The glass-glass construction replaces the standard plastic backsheet with a second tempered glass layer. This eliminates moisture ingress pathways and chemical corrosion of cells, while the dual glass structure absorbs mechanical stress that typically causes microcracks in conventional panels. An added benefit is fire safety Class A certification, which is relevant for commercial rooftop and industrial ground-mount installations. ### How do N-Type HJT cells differ from mainstream PERC cells, and why does it matter when choosing the Luxor Eco Line series? N-Type HJT cells are boron-free, making them virtually immune to LID (Light Induced Degradation) and PID (Potential Induced Degradation) — the two main causes of premature power loss in PERC modules. The amorphous silicon passivation layers on both sides of the cell also enable superior low-light efficiency. The result is stable, predictable energy output for over 30 years rather than a sharp decline in the first few operating seasons. ### Are the Luxor Solar Eco Line N-Type HJT 720Wp panels compatible with standard inverters and racking systems? Yes. These modules are compatible with all mainstream string inverters and microinverters designed for high-wattage systems. The glass-glass format has a combined frame thickness of approximately 30–35 mm, so racking clamps must support that range — most reputable rooftop and ground-mount systems on the market do. Always verify MPPT voltage ranges with your inverter datasheet, as 720Wp panels can produce higher open-circuit voltages that require proper string sizing. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/lx-el-hjt-gg-bif-sw-est-m132-700-720w-210-en-d9ae8460772f.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | -25 W, lighter, +2.3 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | -30 W, lighter, +2.1 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Hotter, lighter, +2.1 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Hotter, lighter, +2.0 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | -35 W, lighter, +1.9 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | -35 W, lighter, +1.9 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | -35 W, lighter, +1.9 pp | | [Luxor Solar LX-650M/210-132+BiF](https://comparepv.com/panel/luxor-solar-lx-650m-210-132-bif) | 650 W | -55 W, hotter, -1.8 pp | | [Luxor Solar LX-655M/210-132+BiF](https://comparepv.com/panel/luxor-solar-lx-655m-210-132-bif) | 655 W | -50 W, hotter, -1.6 pp | | [Luxor Solar LX-660M/210-132+BiF](https://comparepv.com/panel/luxor-solar-lx-660m-210-132-bif) | 660 W | Hotter, -1.4 pp, -5 yr warranty | | [Luxor Solar LX-665M/210-132+BiF](https://comparepv.com/panel/luxor-solar-lx-665m-210-132-bif) | 665 W | Hotter, -1.3 pp, -5 yr warranty | | [Luxor Solar LX-670M/210-132+BiF](https://comparepv.com/panel/luxor-solar-lx-670m-210-132-bif) | 670 W | Hotter, -1.1 pp, -5 yr warranty | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +100 W, hotter, +2.2 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +95 W, hotter, +2.0 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +90 W, hotter, +1.9 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +85 W, hotter, +1.7 pp | --- Source: https://comparepv.com/panel/luxor-solar-lx-705m-210-132-gg-1 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
