The use of **triple-cut cell** technology significantly reduces energy losses resulting from internal resistance, which translates into higher yields even in low sunlight. This design effectively solves the problem of limited installation space, allowing for high power generation from a small roof area. Thanks to advanced **MBB multi-busbar** technology, the panels show significantly lower susceptibility to harmful micro-cracks and increased resistance to extreme mechanical loads, which guarantees stable operation for decades. What distinguishes this line from market competitors is a unique combination of a low temperature coefficient and an exceptionally aesthetic design that blends perfectly with modern architecture. **LCOE cost optimization** ensures that every kilowatt-hour is produced more cheaply, which directly accelerates the return on investment in photovoltaics. This series is dedicated primarily to the residential sector, where **high power density** and the absolute reliability of components in variable climatic conditions typical of Poland are of key importance. This is an uncompromising solution for investors looking for premium segment technology, combining innovation with high module performance standards. ## Notable figures - 21.6% module efficiency - 1.0pp better than the \*\*PERC 400-450W\*\* median of 20.6% - At 215.9 W/m² power density, this panel generates 9.7 W/m² more per unit area than \*\*PERC 400-450W\*\* median (206.2 W/m²) - At -0.34%/°C, hot weather performance is typical for \*\*PERC 400-450W\*\* panels - In the top 55% for efficiency among all PERC panels ## Questions ### Are Risen Titan S panels still available for purchase? The Risen Titan S series has been discontinued and is no longer in active production. If you need similar specifications, consider newer Risen lineups or other Tier 1 manufacturers offering PERC or TOPCon technology. It is worth checking with authorized distributors, as limited warehouse stock may still be available. ### What warranty does Risen offer on the Titan S series? Risen provides a 12-year product warranty and a 25-year linear power output warranty on the Titan S series. This guarantees that modules maintain output above the declared threshold for a quarter century. As a Tier 1 manufacturer, Risen's financial standing supports reliable warranty claim fulfillment in the event of defects or power degradation. ### How does the triple-cut cell technology in Risen Titan S panels work? Risen Titan S uses PERC cells based on 210 mm silicon wafers divided into three equal segments. Smaller cell segments carry lower current, reducing resistive losses and thermal stress. Combined with multi-busbar (MBB) interconnection, this design delivers higher overall efficiency and significantly reduces the risk of microcrack formation compared to standard full-cell modules. ### Does the Risen Titan S perform well in low-light conditions and Central European climates? Yes. The combination of PERC cells, triple-cut design, and MBB busbars improves energy yield under diffuse irradiance and low sun angles - conditions prevalent in Poland during autumn and winter. A low temperature coefficient also ensures efficient operation on cold, sunny days when cell temperatures drop well below 25°C. ### What is the maximum power output of a Risen Titan S panel, and is it suitable for small rooftops? The Risen Titan S series reaches up to 420 Wp peak power. High power density - achieved through 210 mm triple-cut PERC cells - enables substantial energy output from a smaller roof area. This makes it an excellent choice for residential buildings with limited mounting space where maximizing array output without expanding the footprint is a priority. ### Is Risen Energy a reliable solar panel manufacturer worth considering? Risen Energy is a Chinese manufacturer consistently rated Tier 1 by independent analytical agencies, indicating strong financial stability and the capacity to honor 25-year warranty obligations. The company operates its own production lines, implements PERC technology, and positioned the Titan S as a premium residential product - making it a credible choice for prosumer PV installations. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HSA_RSM40-8-395-420M_IEC1500V-30mm_2023H1-2-EN-4e3c49a7f15e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Just Solar JST-EDMH-(445-465)W-TD (465W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-465w-class) | 465 W | +50 W, +2.2 pp, +5 yr warranty | | [Luxor Solar LX-465M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-465m-182r-96-gg) | 465 W | +50 W, cooler, +2.2 pp | | [AIKO AIKO-A460-MAH54Mb](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a460-mah54mb-1) | 460 W | Cooler, +2.0 pp, +5 yr warranty | | [Luxor Solar LX-465M/182R188-108+ GG](https://comparepv.com/panel/luxor-solar-lx-465m-182r188-108-gg) | 465 W | +50 W, cooler, +2.0 pp | | [Just Solar JST-EDMH-(445-465)W-TD (460W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-460w-class) | 460 W | +45 W, +2.0 pp, +5 yr warranty | | [Luxor Solar LX-460M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-460m-182r-96-gg) | 460 W | Cooler, +1.9 pp, +5 yr warranty | | [Philadelphia Solar PS-MNB108(HCBF)-460W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-460w) | 460 W | Cooler, +1.9 pp, +5 yr warranty | | [JA Solar JAT54S40-460/LR](https://comparepv.com/panel/ja-solar-jat54s40-460-lr) | 460 W | Cooler, +1.9 pp, +5 yr warranty | | [Risen RSM40-8-395M](https://comparepv.com/panel/risen-energy-co-ltd-rsm40-8-395m) | 395 W | -20 W, -1.1 pp | | [Risen RSM40-8-400M](https://comparepv.com/panel/risen-energy-co-ltd-rsm40-8-400m) | 400 W | -15 W, -0.8 pp | | [Risen RSM40-8-405M](https://comparepv.com/panel/risen-energy-co-ltd-rsm40-8-405m) | 405 W | -10 W, -0.5 pp | | [Risen RSM40-8-410M](https://comparepv.com/panel/risen-energy-co-ltd-rsm40-8-410m) | 410 W | -0.3 pp | | [Risen RSM40-8-420M](https://comparepv.com/panel/risen-energy-co-ltd-rsm40-8-420m) | 420 W | Very close match | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +95 W, cooler, +3.4 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +80 W, cooler, +3.2 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +90 W, cooler, +3.1 pp | --- Source: https://comparepv.com/panel/risen-energy-co-ltd-rsm40-8-415m 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.
