The construction of this series is based on an innovative combination of monocrystalline cells with multi-busbar architecture, which effectively shortens the electron flow path and increases the overall efficiency of the module. A key distinguishing feature is **double-sided cell activity (bifacial)**, which allows for additional harvesting of energy reflected from the ground, significantly increasing the profitability of investments in areas with high albedo. Thanks to the use of **dual-glass technology**, these modules exhibit extreme resistance to potential-induced degradation (PID) and aggressive chemical factors such as ammonia vapors or salt mist. This is an ideal solution for investors looking for components with a **minimum annual degradation rate**, ensuring stable cash flows over decades of operation. The TITAN series solves the problem of performance drops at high temperatures through an **optimized thermal profile**, placing it at the forefront of products dedicated to operating in the demanding Polish climate. By choosing RSM144-9-BMDG, you are opting for a product that, by reducing construction and cabling costs, offers an unrivaled quality-to-price ratio in the professional market. ## Notable figures - Efficiency of 21.1% is 1.6pp below the \*\*TOPCon 500-550W\*\* median (22.7%) - 211.0 W/m² power density is 16.4 W/m² below \*\*TOPCon 500-550W\*\* median (227.4 W/m²) - requires larger installation area - At -0.34%/°C, loses 0.05pp more power per degree than \*\*TOPCon 500-550W\*\* median (-0.29%/°C) - At 32.5 kg (5.5 kg above \*\*TOPCon 500-550W\*\* median of 27.0 kg), requires checking roof load capacity - Bifacial design (70% factor) captures reflected light - adds 4-10% yield on ground-mount or white roof ## Questions ### What warranty does the Risen TITAN RSM144-9-BMDG come with and what does it cover? The TITAN RSM144-9-BMDG series includes a 15-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. The manufacturer guarantees an annual degradation rate of approximately 0.45% after the first year, ensuring more than 84.9% of rated power is retained after 30 years of operation. This is among the strongest performance commitments available in the p-type dual glass segment. ### What are the real-world benefits of bifacial technology in the Risen RSM144-9-BMDG, and is the premium worth it? Bifacial cells harvest energy from both the front surface and light reflected off the ground (albedo gain). With a bifaciality factor of approximately 70%, installations over light-colored surfaces such as gravel, white EPDM membranes, or snow can realistically achieve 5-15% additional energy yield at no extra hardware cost. For ground-mount farms and commercial flat rooftops this translates into a measurably shorter payback period compared to monofacial modules. ### How do Risen TITAN RSM144-9-BMDG panels perform during summer heat? All PV modules lose power as cell temperature rises above 25°C. The RSM144-9-BMDG benefits from an optimized thermal profile achieved through dual glass construction and multi-busbar cell architecture, which shortens the electron path and lowers internal resistance. The result is reduced thermal losses compared to older single-glass PERC modules - a meaningful advantage during peak summer conditions, especially for large installations where thermal losses directly affect LCOE. ### Are Risen TITAN RSM144-9-BMDG panels better suited for ground-mount or rooftop installations? The RSM144-9-BMDG series, with modules rated up to 550 Wp in a large dual glass format, is designed primarily for utility-scale and commercial applications: ground-mount solar farms and flat industrial rooftops. High per-panel power reduces BoS costs - fewer modules, less cabling, fewer MPPT inputs. Bifacial gain is maximized in elevated ground-mount racking above a high-albedo surface, making this configuration the most economically efficient use case. ### Are Risen RSM144-9-BMDG panels resistant to salt mist and ammonia - can they be used near the coast or livestock farms? Yes. The dual glass construction replaces the conventional backsheet, eliminating the primary ingress path for corrosive substances. BMDG series modules carry salt mist and ammonia resistance certifications, making them suitable for coastal installations and agrivoltaic projects near livestock buildings. As a Tier 1 manufacturer, Risen Energy backs these ratings with independently verified test documentation. ### What accounts for the 550 Wp peak power of the Risen TITAN RSM144-9-BMDG? The top-bin variant reaches 550 Wp under STC conditions. This high power density results from combining 144 half-cut monocrystalline cells with a multi-busbar architecture that reduces resistive losses and lowers the risk of micro-cracks, plus bifacial cell technology. Compared to legacy 4- or 5-busbar layouts, the multi-busbar design also improves partial-shade resilience, delivering higher real-world energy yield over the module's lifetime. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/7f205767e97cab1df574d9e5.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +3.9 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +3.7 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +3.7 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +3.6 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | Cooler, lighter, +3.6 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +3.5 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +3.4 pp | | [Risen RSM144-9-550BMDG](https://comparepv.com/panel/risen-rsm144-9-550bmdg) | 550 W | Very close match | | [Risen RSM144-9-560BNDG](https://comparepv.com/panel/risen-energy-co-ltd-rsm144-9-560bndg) | 560 W | +15 W, cooler, +0.6 pp | | [Risen RSM144-9-565BNDG](https://comparepv.com/panel/risen-energy-co-ltd-rsm144-9-565bndg) | 565 W | +20 W, cooler, +0.8 pp | | [Risen RSM144-9-570BNDG](https://comparepv.com/panel/risen-energy-co-ltd-rsm144-9-570bndg) | 570 W | +25 W, cooler, +1.0 pp | | [Risen RSM144-9-575BNDG](https://comparepv.com/panel/risen-energy-co-ltd-rsm144-9-575bndg) | 575 W | +30 W, cooler, +1.2 pp | | [Risen RSM144-9-580BNDG](https://comparepv.com/panel/risen-energy-co-ltd-rsm144-9-580bndg) | 580 W | +35 W, cooler, +1.4 pp | | [Risen RSM144-9-585BNDG](https://comparepv.com/panel/risen-energy-co-ltd-rsm144-9-585bndg) | 585 W | +40 W, cooler, +1.5 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +105 W, cooler, +4.1 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +100 W, cooler, +3.9 pp | --- Source: https://comparepv.com/panel/risen-rsm144-9-545bmdg 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.
