Thanks to the use of **innovative TOPCon technology**, these modules offer a significantly higher energy yield compared to traditional solutions, especially in low sunlight conditions. The **dual glass** construction, or glass-glass, ensures extreme resistance to weather factors and corrosion, making them an ideal choice for demanding locations such as coastal or agricultural areas. This series effectively addresses the issue of performance drops at high temperatures, offering one of the market-s best **low temperature coefficients**. Thanks to **high bifaciality**, these panels generate additional power from reflected light, which optimizes the profitability of investments in ground-mounted farms and commercial installations. What sets this series apart from the competition is the combination of longevity resulting from double glass protection and the stability of electrical parameters over decades. By choosing these modules, investors receive a guarantee of **reliability and maximum yields**, regardless of the prevailing weather conditions. This is a professional solution for those seeking premium technology that realistically shortens the return on investment for PV systems. ## Notable figures - At 21.6% efficiency, this panel is on par with typical \*\*TOPCon 400-450W\*\* modules - At 215.6 W/m², this panel generates 4.6 W/m² less per unit area than \*\*TOPCon 400-450W\*\* median (220.2 W/m²) - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 400-450W\*\* panels - Weight of 25.0 kg is 3.0 kg above \*\*TOPCon 400-450W\*\* median (22.0 kg) - verify structural support - Ranked #7716 out of 14129 panels for efficiency in the database ## Questions ### What warranty comes with the Risen n-type TOPCon HIGH PERFORMANCE DUAL GLASS MODULE? The Risen n-type TOPCon DUAL GLASS series carries a 15-year product warranty covering material and workmanship defects, along with a 30-year linear power warranty. Over that 30-year period, Risen guarantees a minimum power retention of 87.4%, with annual degradation of just 0.4%. This is among the longest power warranties available in the residential and commercial PV module market. ### What is TOPCon technology and why is it better than standard PERC? TOPCon (Tunnel Oxide Passivated Contact) uses n-type silicon cells that are immune to light-induced degradation (LID), a common issue with p-type PERC modules. As a result, Risen TOPCon panels lose less power from day one and maintain higher efficiency over 30 years. The temperature coefficient of -0.29%/°C also means better output on hot summer days compared to typical PERC cells. ### Are the Risen TOPCon DUAL GLASS panels suitable for ground-mounted farms, and does bifaciality actually increase yield? Yes. With a bifaciality factor of approximately 80%, the DUAL GLASS series is optimized for ground-mounted installations. The rear glass captures reflected irradiance from light-colored ground surfaces (sand, gravel, snow), boosting total energy yield by 5-20% compared to monofacial modules under the same conditions. At up to 465 Wp nominal power, the series delivers strong ROI for utility-scale and commercial PV projects. ### Can the dual glass design withstand harsh environments like coastal or agricultural sites? Yes. The heat-strengthened glass backsheet replaces a conventional polymer rear foil, providing superior resistance to moisture ingress, corrosion, and ammonia exposure. Risen DUAL GLASS modules are certified to IEC 61215 for snow and wind load, making them a preferred choice for coastal, agricultural, and industrial sites where standard backsheet panels degrade faster over time. ### What is the peak power output of the Risen n-type TOPCon DUAL GLASS MODULE, and are they compatible with standard inverters? The maximum peak power in this series is 465 Wp under STC. The electrical parameters (Voc, Isc) fall within the input range supported by most string and hybrid inverters on the market, including SMA, Fronius, Huawei, and SolarEdge. Always verify the open-circuit voltage Voc for your specific model against the inverter's maximum DC input voltage before system design. ### Is Risen a trustworthy manufacturer for a 30-year PV investment? Risen Energy is a Bloomberg NEF Tier 1 rated manufacturer, confirming the financial strength and production scale required to back long-term warranties. Founded in 1986 and operating its own manufacturing facilities in China, Risen holds IEC, MCS, and other international certifications, enabling eligibility for subsidies and net-metering programs across Poland and the broader EU market. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/RSM108-10-440-465NDG_IEC1500V-30mm_2024H1-3-EN-3f27e9572b6a.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +50 W, lighter, +2.9 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +50 W, lighter, +2.9 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +45 W, lighter, +2.7 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +45 W, lighter, +2.7 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +45 W, lighter, +2.7 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +45 W, lighter, +2.7 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +45 W, cooler, +2.7 pp | | [Risen RSM108-10-435BNDG](https://comparepv.com/panel/risen-energy-rsm108-10-435bndg) | 435 W | -0.3 pp | | [Risen RSM108-10-445BNDG](https://comparepv.com/panel/risen-energy-rsm108-10-445bndg) | 445 W | Very close match | | [Risen RSM108-10-450BNDG](https://comparepv.com/panel/risen-energy-rsm108-10-450bndg) | 450 W | +10 W, +0.5 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +70 W, cooler, +3.4 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +55 W, lighter, +3.2 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +65 W, cooler, +3.1 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +65 W, cooler, +3.1 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +60 W, cooler, +2.9 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +60 W, lighter, +2.9 pp | --- Source: https://comparepv.com/panel/risen-rsm108-10-440ndg Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
