Middle of its segment, modest efficiency
The Risen RSM132-11-605-630BNDG series are modern modules based on n-type i-TOPCon cells, designed for maximum energy production in real-world conditions. The application of bifacial construction allows for the use of reflected light, performing exceptionally well on bright roofs, membranes, concrete surfaces, and ground-mounted installations - where additional yield matters without increasing the occupied area.
Compared to many standard modules, they stand out due to their dual-glass format, which enhances resistance to environmental factors and supports stable parameters over a long period. The n-type technology minimizes typical degradation mechanisms, and the declared anti-LID and anti-PID resistance helps maintain performance in challenging installations, such as those with higher system voltages or demanding humidity conditions.
This is an excellent choice for utility-scale PV farms, industrial and commercial applications, and projects where the priority is high kWh yield and predictable operation year after year.
Ranking
Signals from the data
Commercial, utility-scale and shaded-installations.
Tight roof space and roofs where every square metre has to count.
Bottom 23% of the TOPCon 600-650 W segment, against a median of 22.80%.
Bottom 23% of the TOPCon 600-650 W segment, against a median of 227.7.
N-type TOPCon technology reduces typical degradation mechanisms (LID, PID) and delivers better high-temperature performance than older PERC cells, resulting in more stable energy yield over the module's lifetime.
Peak efficiency of 23.3% matches the best TOPCon modules in the segment, including Canadian Solar TOPBiHiKu6 (23.3%), Resun RS8H-M-BD (23.32%), and Jinko Tiger Neo 66HL4M-BDV (23.32%), putting the series on par with market leaders.
The dual-glass format combined with bifacial technology captures light reflected from the ground, boosting yield on bright roofs, membranes, and concrete surfaces without increasing installed area, while also improving resistance to environmental stress.
The manufacturer's stated 30-year power warranty exceeds the standard 25-year period common among competitors, increasing long-term energy production predictability for investors.
Risen is a Tier-1 bankable manufacturer operating since 1986, which simplifies project financing and lowers investor risk for PV farms and commercial installations.
The 15-year product warranty is shorter than the standard already adopted by some leading Tier-1 manufacturers, who now offer 20-25 year product warranties on new TOPCon series alongside the same 30-year power warranty.
- At 22.4% efficiency, this panel is on par with typical TOPCon 600-650W modules
- Power density of 224.0 W/m² is 3.7 W/m² below TOPCon 600-650W median (227.7 W/m²) - needs more roof space
- Temperature coefficient of -0.29%/°C matches the TOPCon 600-650W median
- 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces
- In the top 34% for efficiency among all TOPCon panels
