HJT technology combines the strengths of crystalline and thin-film cells, delivering higher yield per unit of roof area. - **30-year product and power warranty** - Recom offers 30 years of both product and power warranty - substantially longer than the standard 12-15 year product warranty and 25-year power warranty offered by most tier-1 manufacturers (e.g., Trina, JA Solar). For investors, this means a longer horizon of predictable ROI. - **Double-glass construction and bifaciality** - Double glass construction increases mechanical durability and limits moisture-related degradation compared to backsheet designs, directly supporting the 30-year warranty claim. High bifaciality of the HJT cells allows the module to additionally harvest rear-side light, particularly cost-effective for ground-mount installations, light-colored roofs, or reflective surfaces. - **LID and PID resistance (N-type cells)** - N-type cells eliminate the Light Induced Degradation (LID) typical of older PERC technology and reduce PID risk, resulting in more stable long-term energy output consistent with the stated power warranty. - **Strong high-temperature performance** - HJT has a lower power temperature coefficient than classic PERC or even TOPCon cells, limiting output losses on hot days - a notable advantage in Polish summer conditions, where panel temperatures can exceed 60°C. ## Cons - **No Tier-1 bankability status** - Unlike some earlier periods, the series does not currently hold Bloomberg Tier-1 status, which can complicate non-recourse financing for large PV projects (>1.5 MW) compared to competitors currently on the tier-1 list. - **Smaller manufacturing scale** - Recom is a manufacturer founded in 2007, headquartered in Italy, with noticeably smaller production scale than industry giants like Trina Solar or JA Solar from the peer comparables - for large, multi-year EPC contracts this may mean higher risk regarding global warranty service availability. ## About this series The Recom Lion series comprises modules based on heterojunction technology (HJT), designed for high energy production even under less-than-ideal conditions. Thanks to their **double-glass** construction, the panels are better able to withstand environmental stresses and are more stable over time, which is appreciated by investors who prioritize predictable energy yield. A key advantage is **high bifaciality** - the module can effectively "collect" light from both sides, increasing the profitability of installations on ground surfaces, light roofs, and surfaces that reflect light. In practice, the Lion Series addresses common installation problems in Poland, such as reduced energy production during hot weather and under poor sunlight conditions. HJT ensures **good performance at high temperatures** and more effective energy capture in the morning, evening, and on cloudy days. Furthermore, the use of N-type cells results in **resistance to LID and PID**, which helps maintain efficiency over the long term. This is a series for demanding applications, from single-family homes to PV farms, where energy yield, durability, and energy costs are key considerations. ## Notable figures - At 23.0% efficiency, this panel is on par with typical \*\*HJT 450-500W\*\* modules - Power density of 230.2 W/m² matches the \*\*HJT 450-500W\*\* median - -0.26%/°C temperature coefficient - 0.02pp worse than \*\*HJT 450-500W\*\* median (-0.24%/°C), expect higher hot weather losses - Bifacial design (90% factor) captures reflected light - adds 4-14% yield on ground-mount or white roof - #1797 for efficiency, #511 for temperature performance out of 14005 panels ## Questions ### Why do Recom Lion Series panels perform better on hot summer days than standard PERC modules? The HJT technology used in the Lion Series delivers a temperature coefficient of approximately -0.24%/°C, compared to -0.35%/°C or worse for typical PERC modules. In practice, when a panel heats up to 70°C, the Lion module loses noticeably less power output than a comparable PERC panel. For rooftop installations where surface temperatures regularly exceed 60°C in summer, this translates into a measurably higher annual energy yield. ### Does the bifacial design of the Recom Lion Series actually increase energy production, and which installations benefit most? The Lion Series achieves a bifaciality factor of up to 90%, meaning the rear side of the panel can generate up to 90% of the power produced by the front side. The greatest gains occur in ground-mounted systems with bright soil or gravel, on flat white rooftops, and wherever reflected light can reach the module's rear surface. Under favorable albedo conditions, bifaciality can add several to over ten percent to annual energy output compared to a monofacial module. ### What warranty does the Recom Lion Series come with, and what does the power output guarantee cover? Recom provides a 30-year product warranty and a 30-year linear power output warranty. The module must retain at least 94.66% of nominal power after 15 years and at least 91.25% after 30 years. These are among the strictest power warranty conditions available for HJT modules on the market. The warranty is transferable, which is relevant if the property with the PV system is ever sold. ### Are Recom Lion Series modules resistant to LID and PID degradation that reduces efficiency in older panels? Yes. The HJT cells in the Lion Series are built on an N-type silicon substrate, which by design does not undergo LID (Light Induced Degradation) caused by boron in P-type cells. The modules also carry certified resistance to PID (Potential Induced Degradation), which is especially important in large-scale PV plants and farms where system voltages are high. This directly results in lower long-term power loss over the module's lifetime. ### What are the dimensions of the Recom Lion Series 460W panel, and will it fit on a typical residential roof? The Recom Lion 460W variant measures approximately 2094 x 1038 x 30 mm in a double-glass configuration. This is a standard format for 144-cell modules and is compatible with most racking systems available on the market. The double-glass construction adds weight compared to framed alternatives, so for older roof structures it is advisable to have a structural load assessment carried out before installation. ### Recom is not listed as a Tier 1 manufacturer — is that a risk when choosing the Lion Series? Tier 1 rankings (Bloomberg NEF) assess a manufacturer's creditworthiness and bankability in large financed projects, not the technical quality of their modules. Recom is an Italian manufacturer with its own HJT production lines and a documented track record in the premium module segment. More relevant than a Tier 1 designation are the warranty terms, the company's financial stability, and the availability of after-sales service through a local distributor. Always verify warranty service conditions with your regional supplier before purchasing. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/rcm-xxx-rdbhaa-xxx-440-460-24-g12r-30-bg-15v-033-2024-04-v8-d8fbbcb56c0c.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +50 W, cooler, +2.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +35 W, lighter, +1.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +45 W, cooler, +1.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +30 W, lighter, +1.5 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +40 W, cooler, +1.5 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +40 W, lighter, +1.5 pp | | [Recom RCM-440-RDBNAA (Lynx series)](https://comparepv.com/panel/recom-rcm-440-rdbnaa-lynx-series) | 440 W | -20 W, hotter, -1.0 pp | | [Recom RCM-445-RDBNAA](https://comparepv.com/panel/recom-rcm-445-rdbnaa) | 445 W | Hotter, lighter, -0.8 pp | | [Recom RCM-450-RDBNAA](https://comparepv.com/panel/recom-rcm-450-rdbnaa) | 450 W | Hotter, lighter, -0.5 pp | --- Source: https://comparepv.com/panel/recom-rcm-460-rdbhaa Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
