Strong in heat, heavy for its output
The RPS2MH72BDXXX series consists of bifacial photovoltaic modules built on M10 PERC cells using half-cut cell technology, designed to maximize energy yield in both rooftop and ground-mounted installations. Thanks to gallium-doped cells and a multi busbar layout, these panels reduce power losses caused by micro-cracking and hot-spot effects, delivering greater reliability under demanding operating conditions. The rear side uses a high-transmission glass cover, allowing the cells to capture additional reflected light from the ground - a feature that performs especially well on solar farms with light-colored surfaces or rooftops covered with reflective membranes. The anodized aluminum frame combined with a reinforced front glass gives the series strong resistance to heavy snow and wind loads, making it a solid choice for installers working in regions with variable climate conditions. The modules also stand out for stable performance in low-light conditions - early morning, sunset, or overcast weather - which meaningfully boosts annual energy output. This solution is aimed at both commercial investors and residential installers looking for a balance between performance, durability, and predictable LCOE over the system's lifetime.

Utility-scale, commercial, shaded-installations and cold-climate.
Weight-limited structures.
Top 3% of the PERC 550-600 W segment, against a median of -0.350. Ranked 8,312th in the whole database.
Top 25% of the PERC 550-600 W segment, against a median of 27 yrs.
Bottom 15% of the PERC 550-600 W segment, against a median of 52.7.
A high-transmission rear glass lets the module capture additional light reflected from the ground, boosting annual yield - particularly on PV farms with light-colored ground or rooftops with light-colored membranes, where typical bifacial gain is 5-15% depending on albedo.
Gallium doping combined with multi-busbar and half-cut cell architecture reduces power losses from microcracks and hot-spot effects, improving reliability compared to older single-busbar designs.
The anodized aluminum frame and reinforced front glass withstand up to 5400 Pa of snow load and 2400 Pa of wind load, placing the series in the upper tier of the segment for mechanical durability.
The manufacturer guarantees 30 years of power warranty with 2% first-year degradation and 0.45% annual degradation thereafter, retaining roughly 85% of rated power after 30 years - a result on par with leading Tier-1 series.
The panels show improved output at low angles of incidence (early morning, dusk, overcast days), which meaningfully increases annual energy yield for both commercial and residential installations.
The series is built on PERC (M10) cells, while the same manufacturer already offers bifacial TOPCon M10 modules rated up to 590 Wp with higher efficiency - RPS2MH72BDXXX represents an older technology generation with limited headroom for further efficiency gains.
- Efficiency of 21.3% matches the PERC 550-600W median
- At 212.9 W/m² power density, roof space requirements are typical for PERC 550-600W panels
- -0.32%/°C temperature coefficient (median: -0.35%/°C) - retains ~1% more power at high temperatures
- At 32.5 kg (1.7 kg above PERC 550-600W median of 30.8 kg), requires checking roof load capacity
- 70% bifaciality enables rear-side power generation, boosting yield by 4-10% on reflective surfaces
