**30-year power warranty with low degradation** - An annual power degradation rate of only 0.45%, combined with a 30-year power warranty, matches figures typically seen from leading Tier-1 manufacturers, providing predictable energy yield over the system's full lifetime. - **High mechanical durability** - The anodized aluminum alloy frame withstands wind loads up to 2400 Pa and snow loads up to 5400 Pa, placing the modules above typical industry standards and making them suitable for demanding climate conditions such as those in Poland. - **Anti-reflective and hydrophobic coating** - The combination of anti-reflective and hydrophobic coating on the tempered glass increases light absorption and enables self-cleaning of the surface, meaningfully reducing maintenance costs in large commercial and industrial installations. - **Competitive unit power vs. peers** - The maximum power of 430 Wp matches leading peer comparables such as Silfab Elite (430 Wp) and EGing STAR Pro (430 Wp), delivering comparable power density per roof area at a price point typically lower than non-Tier-1 manufacturers. ## Cons - **Production discontinued** - The 72 Cell Monocrystal series has been discontinued, meaning limited availability of warranty service and replacement parts, and potentially complicated future warranty claims. - **Manufacturer not on Tier-1 bankable list** - Lexron (ACS Enerji), a Turkish manufacturer founded in 2010, does not appear on the BNEF Tier-1 bankable manufacturer list, which can complicate financing for commercial projects that require lender-approved suppliers. - **Efficiency below segment leaders** - The maximum efficiency of 21.62% trails comparable models such as Silfab Elite (21.9%) and EGing STAR Pro (22.02%) at the same 430 Wp power rating, meaning slightly more roof area is needed to achieve the same installed capacity. ## About this series The **Lexron 72 Cell Monocrystalline** series is a range of photovoltaic modules based on the **PERC technology with monocrystalline cells**, designed for installations that require high power and reliability in demanding conditions. The use of a five-busbar cell architecture (5BB) shortens the current flow paths and minimizes resistive losses, resulting in improved module performance even under partial shading. These modules are distinguished by a **anti-reflective and hydrophobic coating on the tempered glass** - this combination increases light absorption and allows for self-cleaning of the surface, reducing maintenance costs in remote locations. The robust construction with an **anodized aluminum alloy frame** allows it to withstand wind loads of up to 2400 Pa and snow loads of up to 5400 Pa, making these panels suitable for Polish climatic conditions. The series performs exceptionally well in **large commercial and industrial installations**, where high individual power and long-term production stability are crucial. The guaranteed **30-year power warranty** with an annual degradation of only 0.45% ensures predictable returns on investment and minimal financial risk throughout the lifespan of the installation. ## Notable figures - 21.1% module efficiency - 0.5pp better than the \*\*PERC 400-450W\*\* median of 20.6% - 211.2 W/m² power density - 5.0 W/m² more than \*\*PERC 400-450W\*\* median (206.2 W/m²), more power per roof area - At -0.35%/°C, hot weather performance is typical for \*\*PERC 400-450W\*\* panels - #9255 for efficiency, #10419 for temperature performance out of 14005 panels ## Questions ### Is the Lexron 72 Cell Monocrystalline series still available for purchase? The Lexron 72 Cell Monocrystalline series has been discontinued and is no longer offered as a new product. Availability of any remaining stock may vary by distributor. If you need a similar PERC monocrystalline solution with comparable wattage, consider newer series from the same manufacturer or currently available alternatives on the market. ### What are the product and power warranties for Lexron 72 Cell Monocrystalline panels? Lexron 72 Cell Monocrystalline modules come with a 12-year product warranty covering material and manufacturing defects, and a 30-year linear power warranty. The guaranteed annual degradation rate is a maximum of 0.45%, meaning the panels retain over 85% of their original rated output after 30 years. This enables precise long-term energy yield forecasting and minimizes financial risk throughout the system's lifecycle. ### Can Lexron 72 Cell Monocrystalline panels withstand heavy snow loads typical of Central European winters? Yes. The anodized aluminum alloy frame is rated for snow loads up to 5400 Pa and wind loads up to 2400 Pa. For reference, Polish building codes typically require resistance of around 2000–3000 Pa for snow. This makes Lexron 72 Cell modules suitable even for mountainous regions and areas with harsh winter conditions across Poland. ### What is PERC technology used in the Lexron 72 Cell series and is it worth the premium? PERC (Passivated Emitter and Rear Cell) adds a passivation layer to the rear of each cell, reflecting unabsorbed photons back into the silicon structure for a second conversion pass. Combined with a 5-busbar (5BB) architecture that shortens current paths and reduces resistive losses, the result is higher efficiency and better performance under diffuse light compared to standard monocrystalline cells without PERC. ### What type of installations are Lexron 72 Cell Monocrystalline 430 Wp panels best suited for? The Lexron 72 Cell Monocrystalline series at 430 Wp is optimized for large commercial and industrial installations where high per-panel output and long-term production stability are the priority. The large 72-cell format is ideal for expansive rooftops on warehouses, manufacturing facilities, and ground-mounted systems. For small residential rooftop installations, a more compact 60-cell module is generally a better fit. ### Are Lexron 72 Cell Monocrystalline panels bifacial? No, the Lexron 72 Cell Monocrystalline is a standard monofacial module — power is generated from the front surface only. The tempered front glass features an anti-reflective and hydrophobic coating that maximizes light absorption and enables self-cleaning. If you require the additional yield from ground-reflected irradiance (albedo effect), you should consider a bifacial alternative. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/72CELLMONOCRYSTALDATASHEET-e688c094735d.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Just Solar JST-EDMH-(445-465)W-TD (465W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-465w-class) | 465 W | +45 W, cooler, +2.7 pp | | [Luxor Solar LX-465M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-465m-182r-96-gg) | 465 W | +45 W, cooler, +2.7 pp | | [Maxeon SPR-MAX7-470](https://comparepv.com/panel/maxeon-spr-max7-470) | 470 W | Cooler, +2.6 pp, +10 yr warranty | | [AIKO AIKO-A470-MAH54Mb](https://comparepv.com/panel/aiko-aiko-a470-mah54mb) | 470 W | +50 W, cooler, +2.5 pp | | [AIKO AIKO-A460-MAH54Mb](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a460-mah54mb-1) | 460 W | +40 W, cooler, +2.5 pp | | [TCL Zhonghuan HSM-BD54-LA470](https://comparepv.com/panel/tcl-zhonghuan-hsm-bd54-la470) | 470 W | +50 W, cooler, +2.5 pp | | [Lexron 405W](https://comparepv.com/panel/lexron-405w) | 405 W | -15 W, -0.8 pp | | [Lexron 410W](https://comparepv.com/panel/lexron-410w) | 410 W | -10 W, -0.5 pp | | [Lexron 415W](https://comparepv.com/panel/lexron-415w) | 415 W | -0.3 pp | | [Lexron 425W](https://comparepv.com/panel/lexron-425w) | 425 W | +0.2 pp | | [Lexron 430W](https://comparepv.com/panel/lexron-430w) | 430 W | +10 W, +0.5 pp | | [Maxeon SPR-MAX7-475](https://comparepv.com/panel/maxeon-spr-max7-475) | 475 W | Cooler, +2.9 pp, +10 yr warranty | | [Maxeon SPR-MAX7-465](https://comparepv.com/panel/maxeon-spr-max7-465) | 465 W | Cooler, +2.4 pp, +10 yr warranty | | [Lina Energy LEPV 132 ULTRA PREMIUM BLACK 440Wp (LEPV 440)](https://comparepv.com/panel/lina-energy-lepv-132-ultra-premium-black-440wp-lepv-440) | 440 W | +20 W, cooler, +1.2 pp | | [JA Solar NS-420MH-80](https://comparepv.com/panel/ja-solar-ns-420mh-80) | 420 W | Cooler, +1.2 pp, -5 yr warranty | | [PolyCrown Solar Tech NS-420MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-420mh-80) | 420 W | Cooler, +1.2 pp, -5 yr warranty | --- Source: https://comparepv.com/panel/lexron-420w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
