**N-type TOPCon cells** - Efficiency of 21.7-22.6% and lower LID degradation compared to older PERC cells translate into more stable energy yield over the module's lifetime, especially at higher operating temperatures. - **Bifacial dual-glass design** - The bifacial, dual-glass construction captures reflected light from the ground (gravel, membranes, light surfaces), adding extra energy production without increasing array footprint, plus improved resistance to moisture and mechanical loads. - **30-year linear power warranty** - The 30-year linear warranty guaranteeing at least 87% of nominal power meets premium-segment standards and matches comparable n-type series such as Hanersun Hitouch 5N and Q-SUN Qrystal N8/QNN182-HS-72. - **Tier-1 manufacturer with long track record** - Risen Energy, founded in 1986, is recognized as a bankable Tier-1 manufacturer with decades of production experience, strengthening the series' credibility with investors and EPC firms. - **High power density up to 585 Wp** - Unit power of up to 585 Wp in a 144-cell format places the series among the top of the segment, matching the highest-power variants of comparable n-type series (Hanersun, Q-SUN) also topping out at 585 Wp. ## Cons - **Production discontinued in 2023** - The series was discontinued the same year it was released (2023), meaning limited availability on the secondary market and potential difficulties with service and sourcing matching replacement units for installation expansion. - **Short product warranty (5 years)** - The 5-year product warranty is notably shorter than the current standard offered by Tier-1 manufacturers for n-type TOPCon modules, where typical terms run 10-15 years, which may affect the series' perceived investment value. - **Slightly lower efficiency than segment leaders** - Maximum efficiency of 22.6% is marginally below comparable n-type series such as Hanersun Hitouch 5N (22.65%) and Q-SUN Qrystal N8 (22.65%), though the gap is small and has minimal impact on actual energy yield. ## About this series The Risen RSM144-9-560-585BNDG series was designed as **bifacial** modules in a **dual glass** construction, to genuinely increase energy yield where every percent of production counts - on commercial rooftops and large ground installations. The use of **n-type TOPCon** cells translates to more stable performance over time, lower susceptibility to typical degradation mechanisms, and high efficiency even in challenging conditions, when the installation operates beyond ideal irradiance. Dual glass is not just about durability - it also means better resistance to moisture, temperature changes, and loads, facilitating module selection for projects facing demanding environments. Bifaciality helps utilize reflected light (e.g., from light backgrounds, gravel, roof membranes), contributing to additional energy production without increasing the surface area. This series stands out by combining **high power density** with an approach focused on long-term reliability - for investors, EPCs, and companies seeking predictable LCOE and faster returns from their installations. ## Notable figures - At 22.3% efficiency, this panel is on par with typical \*\*TOPCon 550-600W\*\* modules - Power density of 222.6 W/m² matches the \*\*TOPCon 550-600W\*\* median - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 550-600W\*\* median - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface - Ranked #5161 out of 14129 panels for efficiency in the database ## Questions ### Is the Risen RSM144-9-560-585BNDG series still available for purchase? The RSM144-9-560-585BNDG series has been discontinued and is no longer available as new stock from most distributors. Occasional warehouse inventory may still be found, but for new projects it is advisable to look at current Risen n-type TOPCon modules with comparable specs to ensure supply continuity and full manufacturer support. ### What warranties come with the Risen RSM144-9-560-585BNDG modules? Risen provides a 5-year product warranty covering defects and workmanship, plus a 30-year linear power warranty. Annual degradation is just 0.4%, meaning the module should retain at least 87.4% of rated power after 30 years. This is one of the strongest long-term performance guarantees available in the dual glass n-type segment. ### What real-world benefit does the bifacial design of the RSM144-9-560-585BNDG offer, and when does it pay off? The rear side of the module can generate up to approximately 10% additional power by capturing reflected light from the ground surface. The gain is highest where albedo is high: light-colored gravel, white roofing membrane, concrete, or snow. On a standard dark rooftop the benefit is minimal. Bifacial performance pays off most in ground-mounted systems with elevated racking and a reflective surface beneath. ### How does the Risen RSM144-9-560-585BNDG perform in high summer temperatures? The temperature coefficient of Pmax is -0.29%/°C, which is an excellent figure for n-type TOPCon technology. At a panel surface temperature of 70°C, power loss is roughly 11.6% relative to STC, compared to 13-15% for typical p-type PERC modules. This means better real-world yields during hot summer months when irradiance is at its highest. ### Are the Risen RSM144-9-560-585BNDG panels suitable for large commercial and utility-scale PV installations? Yes, this series was specifically engineered for commercial rooftops and utility-scale ground-mounted systems. The 2278×1134×30 mm format and up to 585 Wp per module deliver high power density per unit area. A maximum system voltage of 1500 V DC simplifies integration with commercial string and central inverters, reducing overall BoS costs. ### How does n-type TOPCon technology in this Risen series compare to older PERC cells? TOPCon cells feature a thin tunnel oxide passivation layer on the rear side, which reduces carrier recombination more effectively than PERC. In practice this means higher module efficiency (up to approx. 22.5%), no light-induced degradation (LID) typical of p-type PERC, and a lower temperature coefficient. For investors, the result is higher annual energy yield and a more predictable LCOE over the full system lifetime. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Data-Sheet-Risen-Energy-RSM144-9-560-585BNDG-IEC1500V-30mm-2-2dd57f51db07.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.5 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +2.3 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, lighter, +2.1 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | -35 W, lighter, +2.1 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | -35 W, lighter, +2.1 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | -30 W, lighter, +2.0 pp | | [AIKO AIKO-A625-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a625-mah72dw) | 625 W | +50 W, cooler, +1.9 pp | | [Risen RSM144-9-545BMDG](https://comparepv.com/panel/risen-rsm144-9-545bmdg) | 545 W | -30 W, hotter, -1.2 pp | | [Risen RSM144-9-550BMDG](https://comparepv.com/panel/risen-rsm144-9-550bmdg) | 550 W | -25 W, hotter, -1.0 pp | | [Risen RSM144-9-560BNDG](https://comparepv.com/panel/risen-energy-co-ltd-rsm144-9-560bndg) | 560 W | -15 W, -0.6 pp | | [Risen RSM144-9-565BNDG](https://comparepv.com/panel/risen-energy-co-ltd-rsm144-9-565bndg) | 565 W | -10 W, -0.4 pp | | [Risen RSM144-9-570BNDG](https://comparepv.com/panel/risen-energy-co-ltd-rsm144-9-570bndg) | 570 W | Very close match | | [Risen RSM144-9-580BNDG](https://comparepv.com/panel/risen-energy-co-ltd-rsm144-9-580bndg) | 580 W | Very close match | | [Risen RSM144-9-585BNDG](https://comparepv.com/panel/risen-energy-co-ltd-rsm144-9-585bndg) | 585 W | +10 W, +0.3 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +75 W, lighter, +2.9 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +70 W, lighter, +2.7 pp | --- Source: https://comparepv.com/panel/risen-energy-co-ltd-rsm144-9-575bndg 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.
