**Next-gen N-type TOPCon cells** - N-type TOPCon technology delivers up to 22.3% efficiency and a lower LID/LeTID degradation coefficient than legacy PERC cells, translating into higher lifetime energy yield. - **Dual Glass construction with bifacial gain** - The glass-glass build improves resistance to moisture ingress, microcracking, and PID degradation, while the bifacial design captures additional rear-side irradiance from reflective surfaces such as light-colored roofs or ground. - **Extended product and power warranty** - A 25-year product warranty and 30-year linear power warranty match premium Tier-1 n-type standards and are on par with comparable modules from LEDVANCE and Solitek, giving investors long-term reliability assurance. - **Full-black aesthetics for residential rooftops** - The all-black design (black cells, backsheet, and frame) blends visually with the roof plane, a key purchasing criterion for prosumer installations in the Polish market. - **Tier-1, bankable manufacturer credibility** - Risen Energy, founded in 1986, is classified as a Tier-1 bankable manufacturer, easing project financing (loans, leasing) and providing confidence in industrial-scale production quality. ## Cons - **Series discontinued** - Launched in 2023 and discontinued in 2024, the series has limited availability of replacement units for warranty claims and may complicate matching modules when extending an existing array. - **Slightly lower efficiency than peers** - Maximum efficiency of 22.3% trails comparable modules such as Sunlike Solar's SKT420-455M10 (22.8%) and LEDVANCE's M435-455N54LB-SF-F7 (22.77%), meaning a marginally larger module footprint is needed to reach the same 455 Wp output. ## About this series The Risen Full-black Aesthetic n-type TOPCon Dual Glass Module series defines a new level of elegance and performance in the prosumer installation segment. The use of advanced **n-type TOPCon** technology allows for higher yields per square meter while simultaneously reducing the light-induced degradation effect. This is an ideal solution for investors who do not want to choose between functionality and design. The **full-black aesthetics** make the modules an integral part of the roof surface, which is crucial in modern architecture. The **Dual Glass** design provides exceptional tightness and resistance to extreme weather conditions, eliminating issues related to moisture or chemical corrosion. A standout feature compared to competitors is the **excellent low-light performance**, which in the Polish climate allows for efficient energy generation even on cloudy days. This series is designed for the most demanding users looking for a secure long-term investment. Thanks to the **optimized temperature coefficient**, the panels maintain high efficiency even during summer heat, which effectively increases annual returns from electricity production. This is a comprehensive answer to the needs of modern photovoltaics, combining the durability of glass with the innovation of n-type cells. ## Notable figures - Efficiency of 22.1% matches the \*\*TOPCon 450-500W\*\* median - 220.5 W/m² power density is 4.7 W/m² below \*\*TOPCon 450-500W\*\* median (225.2 W/m²) - requires larger installation area - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 450-500W\*\* panels - At 25.0 kg, weight matches the \*\*TOPCon 450-500W\*\* median - Ranked #6076 out of 14129 panels for efficiency in the database ## Questions ### Is the Risen Full-black Aesthetic n-type TOPCon Dual Glass Module series still available for purchase? The Risen Full-black Aesthetic n-type TOPCon Dual Glass Module series has been officially discontinued. The manufacturer has ceased production, and availability now depends solely on remaining distributor stock. If you are planning an installation based on this series, check current inventory levels as soon as possible, since restocking will not be possible. Other Risen TOPCon modules are worth considering as an alternative. ### What warranty does the Risen Full-black Aesthetic TOPCon Dual Glass series carry? Risen provides a 25-year product warranty covering manufacturing defects and workmanship, along with a 30-year linear power output warranty. The power warranty guarantees the modules will retain at least a specified percentage of their rated 455 Wp output after three decades of operation. This is one of the longest power warranties available in the residential prosumer segment, reflecting Risen's confidence in the durability of the n-type TOPCon cells and Dual Glass construction. ### How does n-type TOPCon cell technology in these Risen panels compare to standard PERC modules? N-type TOPCon cells deliver higher conversion efficiency, a lower temperature coefficient, and significantly reduced light-induced degradation (LID) compared to conventional PERC modules. In practice, this means more energy generated per square meter of roof area over the system's lifetime. In climates with high summer temperatures, where panel surface temperatures can exceed 70°C, TOPCon's optimized temperature coefficient provides a measurable boost in annual energy yield. ### How do the Risen Full-black TOPCon Dual Glass panels perform on overcast days? N-type TOPCon technology is known for excellent low-light performance, which is particularly valuable in climates with frequent cloud cover. Compared to older PERC cells, n-type modules generate proportionally more power at low irradiance levels. This translates into higher annual energy yields even in less sunny locations, making the Risen Full-black TOPCon Dual Glass series well-suited for prosumer installations where maximizing output across all weather conditions is a priority. ### Why does this Risen series use Dual Glass construction instead of a conventional polymer backsheet? The Dual Glass design replaces the standard polymer backsheet with a second pane of tempered glass, eliminating risks such as chemical corrosion, moisture ingress, and backsheet cracking after years of exposure. The module gains significantly improved mechanical and chemical resistance, which is especially relevant in harsh weather environments. The added durability supports Risen's 30-year power output warranty and provides the structural foundation for bifacial energy harvesting from the rear of the module. ### Does the bifacial design of these Risen panels offer real benefits on a pitched roof? Bifacial modules like this Risen series can harvest additional energy from reflected light via the albedo effect, but the greatest gains occur in ground-mount or flat-roof installations where a bright, reflective surface lies beneath the array. On a typical pitched roof with dark tiles or metal sheeting, energy gain from the rear glass is minimal. For pitched-roof applications, the primary advantages of this series remain the all-black aesthetic and the high efficiency of the n-type TOPCon cells. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/RSM108-10-435-455NDGB_IEC1500V-30mm_2024H1-3-EN-deeb6c36dd0e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +45 W, lighter, +2.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +40 W, lighter, +2.4 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +50 W, cooler, +2.4 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +50 W, lighter, +2.4 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +50 W, lighter, +2.4 pp | | [GCL GCL-NR10R/54BGDF](https://comparepv.com/panel/gcl-gcl-nr10r-54bgdf) | 500 W | +50 W, cooler, +2.4 pp | | [Risen RSM108-10-435BNDG](https://comparepv.com/panel/risen-energy-rsm108-10-435bndg) | 435 W | -15 W, -0.8 pp | | [Risen RSM108-10-440BNDG](https://comparepv.com/panel/risen-energy-rsm108-10-440bndg) | 440 W | -10 W, -0.5 pp | | [Risen RSM108-10-445BNDG](https://comparepv.com/panel/risen-energy-rsm108-10-445bndg) | 445 W | -0.3 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +60 W, cooler, +2.9 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +55 W, cooler, +2.6 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +55 W, cooler, +2.6 pp | --- Source: https://comparepv.com/panel/risen-rsm108-10-450ndgb 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.
