This may complicate non-recourse project financing with some banks compared to consistently Tier-1-listed manufacturers like Tongwei. - **No bifacial variant in this configuration** - The series described in the context is monofacial (is\_bifacial: false), while comparable peer modules such as Tongwei 72HD580-600W and Astronergy ASTRO N5 are offered in bifacial versions that generate an additional 5-15% rear-side yield. ## About this series The Recom Lynx series consists of modules based on **N-type cells in TOPCon technology**, designed for high energy production and stable operation over many years. This translates to better performance in real-world conditions, especially when the installation heats up in summer or operates in full sunlight for extended periods. A key advantage of this series is **minimal susceptibility to LID degradation and limited LeTID risk**, which helps maintain predictable results and protect the investment's profitability. Bifacial modules utilize light from both the front and back sides, and the **glass-glass construction** increases resistance to weather and mechanical stresses. An additional advantage is **quality control through electroluminescence testing**, which supports the detection of microcracks during production. Recom Lynx is suitable for both commercial and industrial installations, as well as larger ground-mounted projects, wherever long-term reliability, low energy costs, and maximum utilization of available space are important. ## Notable figures - Efficiency of 22.5% matches the \*\*TOPCon 450-500W\*\* median - Power density of 225.2 W/m² matches the \*\*TOPCon 450-500W\*\* median - At -0.28%/°C, hot weather performance is typical for \*\*TOPCon 450-500W\*\* panels - 21.0 kg weight - 3.0 kg lighter than \*\*TOPCon 450-500W\*\* median (24.0 kg), reducing installation effort - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### What warranty comes with Recom Lynx panels and what does it cover? The Recom Lynx series includes a 30-year product warranty and a 30-year linear power output guarantee. At the end of the warranty period, the module must retain at least 87.4% of its nominal power output. For a 600 Wp panel, that means a minimum of roughly 524 Wp after 30 years. This warranty protects the financial returns of the investment throughout the full expected operating life of the system. ### What is TOPCon technology and why does the Recom Lynx series use it? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology that delivers higher efficiency and lower degradation than conventional PERC cells. In the Recom Lynx series this translates to minimal LID (Light-Induced Degradation) and reduced LeTID risk. In practice the installation generates more energy annually and retains its rated performance more reliably over decades of operation. ### Do Recom Lynx panels perform well in summer heat? Yes. One of the main advantages of the N-type TOPCon cells in the Recom Lynx series is a low temperature coefficient of approximately -0.29%/°C. Older PERC modules typically range from -0.34% to -0.37%/°C. On a hot summer day when module temperature exceeds 70°C, the Lynx loses proportionally less power than previous-generation technology, resulting in higher annual energy yield in real-world conditions. ### What type of installations is the Recom Lynx series with up to 600 Wp suited for? Recom Lynx modules up to 600 Wp are designed primarily for commercial, industrial, and utility-scale ground-mount solar projects. The high per-module power rating reduces the total number of modules needed and lowers BoS costs including cabling, racking, and MPPT inverter inputs. Due to their large format and weight, these modules are generally not the optimal choice for small residential rooftop installations. ### Is Recom a Tier-1 manufacturer and do they offer service support? Recom Technologies, headquartered in Italy, is not currently listed as a Tier-1 manufacturer by major rating agencies. It is important to note that Tier-1 is a financial bankability classification, not a product quality rating. Before purchasing, buyers should confirm warranty service conditions with their local distributor and verify that an authorized service representative is available in their region, which is especially critical for large commercial projects. ### Do Recom Lynx panels undergo electroluminescence testing, and what does that mean for buyers? Yes, every module in the Recom Lynx series undergoes electroluminescence (EL) quality inspection during manufacturing. EL testing detects microcracks in solar cells that are invisible to the naked eye before the panel leaves the factory. This significantly reduces the risk of early degradation caused by hidden production defects and directly supports the long-term reliability that the series is designed to deliver. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/rcm-xxx-rdbnaaxxx445-470-16-g12r-30-bg-15v-051-2025-05-v1-0-c5809b7c92f1.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +45 W, cooler, +2.3 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +40 W, cooler, +2.0 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +50 W, cooler, +2.0 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +50 W, cooler, +2.0 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +50 W, cooler, +2.0 pp | | [GCL GCL-NR10R/54BGDF](https://comparepv.com/panel/gcl-gcl-nr10r-54bgdf) | 500 W | +50 W, heavier, +2.0 pp | | [Recom RCM-440-RDBNAA (Lynx series)](https://comparepv.com/panel/recom-rcm-440-rdbnaa-lynx-series) | 440 W | -10 W, heavier, -0.5 pp | | [Recom RCM-445-RDBNAA](https://comparepv.com/panel/recom-rcm-445-rdbnaa) | 445 W | -0.2 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +60 W, cooler, +2.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +55 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/recom-rcm-450-rdbnaa 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.
