This means a genuinely lower annual power degradation over the module's full service life. - **G12R TOPCon cells with MBB technology** - The use of rectangular G12R N-type TOPCon cells combined with a multi-busbar (MBB) grid reduces losses under partial shading and lowers the risk of microcracks, resulting in more stable performance parameters compared to older PERC cells. - **Bifacial double-glass module design** - The bifacial construction with double glass (2 mm) captures light reflected off the ground without increasing the installed footprint, which is particularly valuable on bright industrial rooftops or ground-mounted PV farms. - **High efficiency on par with segment leaders** - Efficiency of up to 22.77% matches the LEDVANCE M435~455N54LB-SF-F7 module and is only marginally below the Sunlike Solar SKT420~455M10-108D6 (22.8%), placing the N series among the top-tier comparable modules in the 435-455 Wp range. - **Low power temperature coefficient** - A Pmax temperature coefficient of -0.3%/°C outperforms the typical -0.35%/°C found in competing PERC modules, meaning lower power losses at high operating temperatures on roofs or PV farms. ## Cons - **No confirmed BNEF Tier-1 status** - Available sources (including the ENF Solar datasheet aggregator) provide no independent verification of RedSolar's Tier-1 manufacturer status or third-party lab test results (e.g., PVEL, TÜV), unlike well-established brands in the peer comparable set such as LEDVANCE. This may require additional due diligence for bank-financed commercial projects. ## About this series The RedSolar N series comprises bifacial modules built on **TOPCon technology** and **rectangular G12R cells**, combining high power density with reduced losses under partial shading. The multi-busbar (MBB) structure improves current collection and lowers the risk of microcracks, helping the panels maintain stable output over their entire service life. The **bifacial double-glass design** captures light reflected from the ground, meaningfully boosting energy yield without expanding the footprint of the installation - a feature especially valuable for solar farms and industrial rooftops, where every extra watt matters. PID-resistant construction and a low linear power decline make the N series a solid choice for investors focused on predictable long-term returns. This quality is backed by a **30-year linear power warranty** along with a 12-year product warranty, while CE, ISO, and MCS certifications confirm compliance with international standards. These panels suit installers and commercial project developers who demand high durability and minimal service risk while maximizing output from available mounting space. ## Notable figures - At 22.0% efficiency, this panel is on par with typical \*\*TOPCon 400-450W\*\* modules - At 220.2 W/m² power density, roof space requirements are typical for \*\*TOPCon 400-450W\*\* panels - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 400-450W\*\* median - At 23.9 kg, this panel is 1.9 kg heavier than the \*\*TOPCon 400-450W\*\* median (22.0 kg) - more demanding for installation crews - #6329 for efficiency, #6093 for temperature performance out of 14005 panels ## Questions ### How does the TOPCon cell technology used in RedSolar's N series differ from conventional PERC panels? TOPCon (Tunnel Oxide Passivated Contact) is a newer cell generation that reduces carrier recombination through an additional passivation layer beneath the metal contacts. In practice, this delivers higher cell efficiency and a lower power degradation rate compared to conventional PERC. The N series combines this technology with rectangular G12R cells, achieving up to 455 Wp while maintaining stable output throughout the module's service life. ### Do the bifacial panels in the N series actually deliver a higher energy yield? Yes, the bifacial construction with double glass allows the module to capture light reflected from the ground, roof, or a bright surface beneath the installation, boosting energy output without increasing the mounting footprint. The actual gain depends on ground albedo and mounting height - on light gravel or roofing membrane, it can add anywhere from a few to over ten percent more energy than a monofacial module of the same nominal power. ### What warranty comes with RedSolar's N series panels? The manufacturer offers a 12-year product warranty covering material and workmanship defects, along with a 30-year linear power warranty guaranteeing a low, predictable decline in output over time. This is a premium-tier standard aimed at commercial installations and PV farms, where long-term power output stability directly affects return on investment. ### Are N series panels better suited for rooftop or ground-mount installations? Thanks to bifacial technology and high unit power up to 455 Wp, the N series performs best on large, flat industrial rooftops and ground-mounted PV farms, where the module can fully capture light reflected off the ground. On sloped roofs with limited clearance beneath the module, the bifacial advantage is reduced, though the panel still delivers strong power density per unit of area. ### Does the multi-busbar (MBB) structure in RedSolar N panels affect module durability? Yes, the multi-busbar (MBB) structure spreads current across more thin conductive paths, reducing mechanical stress on individual cells and lowering the risk of microcracks during transport, installation, or thermal cycling. It also improves current collection even if a cell is partially damaged, resulting in more stable module performance over the panel's lifetime. ### Are N series panels resistant to PID degradation and suitable for large commercial installations? Yes, N series modules feature PID-resistant (Potential Induced Degradation) construction, addressing power loss caused by voltage potential differences in the long module strings typical of commercial installations and PV farms. Combined with CE, ISO, and MCS certifications and a 30-year linear power warranty, these panels target investors and developers prioritizing minimal service risk and predictable long-term performance. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/17527145180456fadk0-8adc38e20869.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +50 W, cooler, +2.5 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +50 W, cooler, +2.5 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +45 W, lighter, +2.3 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +45 W, cooler, +2.3 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +45 W, cooler, +2.3 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +45 W, cooler, +2.3 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +45 W, cooler, +2.3 pp | | [RedSolar CETC-435TR(GDF)/96](https://comparepv.com/panel/redsolar-cetc-435tr-gdf-96) | 435 W | -0.2 pp | | [RedSolar CETC-445TR(GDF)/96](https://comparepv.com/panel/redsolar-cetc-445tr-gdf-96) | 445 W | +0.2 pp | | [RedSolar CETC-450TR(GDF)/96](https://comparepv.com/panel/redsolar-cetc-450tr-gdf-96) | 450 W | +10 W, +0.5 pp | | [RedSolar CETC-455TR(GDF)/96](https://comparepv.com/panel/redsolar-cetc-455tr-gdf-96) | 455 W | +15 W, +0.8 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +70 W, cooler, +3.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +55 W, cooler, +2.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +65 W, cooler, +2.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +60 W, cooler, +2.5 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +60 W, cooler, +2.5 pp | --- Source: https://comparepv.com/panel/redsolar-cetc-440tr-gdf-96 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.
