This innovative solution allows for significantly higher power density while maintaining compact dimensions, which is key for optimizing limited roof space. The use of advanced **multi-busbar technology** effectively reduces internal energy losses and minimizes the risk of micro-cracks, which directly translates into long-term production stability. Modules from this series effectively solve the problem of low efficiency in difficult conditions, offering high performance even in diffused light. Thanks to an **exceptionally low temperature coefficient**, TITAN panels operate much more efficiently on hot days, clearly distinguishing them from older competitor solutions. These products are dedicated to both conscious prosumers and commercial investors who care about **maximizing return on investment** while simultaneously reducing system LCOE costs. The special reinforced frame design further increases resistance to extreme snow and wind loads. By choosing the TITAN series, you are investing in advanced technology that combines modern cell architecture with the highest durability, making it one of the most cost-effective choices on the Polish photovoltaic market. ## Notable figures - Efficiency of 21.7% matches the \*\*PERC 600-650W\*\* median - At 217.3 W/m² power density, this panel generates 3.5 W/m² more per unit area than \*\*PERC 600-650W\*\* median (213.8 W/m²) - At -0.34%/°C, hot weather performance is typical for \*\*PERC 600-650W\*\* panels - Weight of 30.0 kg (4.0 kg below \*\*PERC 600-650W\*\* median of 34.0 kg) allows easier transport and roof mounting - Ranked #7485 out of 14129 panels for efficiency in the database ## Questions ### What makes the 210 mm cells in Risen TITAN panels stand out? Risen TITAN uses large-format 210 mm silicon cells that enable a peak output of up to 615 Wp per module. The larger cell area combined with multi-busbar technology reduces resistive losses and lowers the risk of micro-cracks. In practice, this means higher power density per square meter of roof space and stable energy production over the entire service life of the system. ### What is the warranty on Risen TITAN solar panels? Risen provides a 12-year product warranty covering material and workmanship defects, plus a 30-year linear power warranty for the TITAN series. Over those 30 years, the panel is guaranteed to retain at least 80.7% of its rated output. A 30-year power warranty is among the longer standards in the industry and reflects the manufacturer's confidence in the durability of its 210 mm PERC technology. ### Is the Risen TITAN RSM120-8-615M a bifacial module? No, the TITAN series in the RSM120-8 variant is a monofacial panel - energy is harvested from the front cell surface only. If your system is installed above a highly reflective surface such as a white TPO membrane or light-colored gravel and you want to capture albedo gain, Risen's bifacial models would be worth considering. For standard pitched roofs, however, the monofacial TITAN module is fully adequate and offers lower system BoS costs. ### Do Risen TITAN panels perform well on hot summer days? Yes. The PERC technology used in the TITAN series features a low temperature coefficient of power (approximately -0.34%/°C), meaning smaller output losses at high temperatures compared to older polycrystalline modules. At a typical cell temperature of 65°C in summer, power degradation is noticeably lower, directly translating into higher annual energy yields and a shorter investment payback period. ### Can Risen TITAN panels withstand heavy snow loads and strong winds? Yes. The TITAN series features a reinforced aluminum frame that meets IEC standards for snow loads up to 5,400 Pa and wind pressure up to 2,400 Pa. These ratings are suitable for the vast majority of locations in Poland, including mountain regions with harsh winters. That said, always verify the technical documentation against a structural engineering assessment before installation. ### Is Risen Energy a reliable manufacturer and is the 30-year warranty realistic? Risen Energy is listed as a Tier 1 manufacturer by BloombergNEF, meeting strict financial and production criteria. The company has been operating since 1986 and is publicly traded on the Shenzhen Stock Exchange, providing financial transparency. This is a key factor when assessing the credibility of the 30-year power warranty - Tier 1 classification is the industry signal that a manufacturer has the resources to honor long-term obligations. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/RSM120-8-590-615M_IEC1500V-35mm_2023H1-1-EN-08d9ddefd187.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, +3.5 pp, +5 yr warranty | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, +3.3 pp, +5 yr warranty | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, +3.1 pp, +5 yr warranty | | [Longi Solar LR8-66HVD-665M](https://comparepv.com/panel/longi-lr8-66hvd-665m) | 665 W | +50 W, cooler, +2.9 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (665W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-665w-class) | 665 W | +50 W, cooler, +2.9 pp | | [Huayao HY665-B144DSS](https://comparepv.com/panel/huayao-hy665-b144dss) | 665 W | +50 W, cooler, +2.9 pp | | [Sunpro Power SPDG665-BC132R12](https://comparepv.com/panel/sunpro-spdg665-bc132r12) | 665 W | +50 W, cooler, +2.9 pp | | [Risen RSM120-8-585BMDG](https://comparepv.com/panel/risen-rsm120-8-585bmdg) | 585 W | Heavier, -1.0 pp, +5 yr warranty | | [Risen RSM120-8-590M](https://comparepv.com/panel/risen-rsm120-8-590m) | 590 W | -25 W, -0.9 pp | | [Risen RSM120-8-595M](https://comparepv.com/panel/risen-rsm120-8-595m) | 595 W | -20 W, -0.7 pp | | [Risen RSM120-8-600M](https://comparepv.com/panel/risen-rsm120-8-600m) | 600 W | -15 W, -0.5 pp | | [Risen RSM120-8-605M](https://comparepv.com/panel/risen-rsm120-8-605m) | 605 W | -10 W, -0.3 pp | | [Risen RSM120-8-610M](https://comparepv.com/panel/risen-rsm120-8-610m) | 610 W | Very close match | | [Gamko New Energy GKA210N120](https://comparepv.com/panel/gamko-new-energy-gka210n120) | 680 W | +65 W, +2.3 pp, +5 yr warranty | | [Gamko New Energy GKA210N120-675](https://comparepv.com/panel/gamko-new-energy-gka210n120-675) | 675 W | +60 W, +2.2 pp, +5 yr warranty | | [Q-SUN Solar QN-670HJT-01](https://comparepv.com/panel/q-sun-solar-qn-670hjt-01) | 670 W | +55 W, cooler, +2.0 pp | --- Source: https://comparepv.com/panel/risen-rsm120-8-615m 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.
