The Risen TITAN RSM110-8-BHDG series consists of advanced Bifacial Dual Glass modules that redefine performance standards in harsh environmental conditions. The use of half-cut cell technology combined with double glass makes these panels exceptionally resistant to potential-induced degradation and atmospheric factors, resulting in a longer lifespan for the entire installation. Thanks to a high bifaciality factor, these modules generate additional energy from radiation reflected off the ground, which is crucial in commercial projects and large photovoltaic farms. The design based on large-format 210 mm silicon wafers allows for a significant reduction in BOS system costs and a lower LCOE. Investors choosing this series primarily gain yield stability throughout the power plant's life cycle, even at high ambient temperatures, thanks to a low temperature coefficient of power. Risen TITAN RSM110-8-BHDG eliminates the problem of rapid efficiency decline in traditional modules, offering increased mechanical resistance to snow and wind loads. It is an ideal solution for demanding investors looking for a balance between modern technology and maximizing return on investment in the Polish climate.

About the TITAN RSM110-8-BHDG series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

What does HJT technology mean in the Risen TITAN RSM110-8-BHDG series, and how does it compare to standard PERC panels?
HJT (Heterojunction Technology) combines N-type monocrystalline silicon cells with thin amorphous silicon layers, delivering higher efficiency and superior high-temperature performance. In the RSM110-8-BHDG series, this results in a temperature coefficient of just -0.24%/°C - roughly 30% better than typical PERC modules at -0.35%/°C. In practice, that means noticeably lower power losses on hot summer days and higher annual energy yields.
What warranties does the Risen TITAN RSM110-8-BHDG come with, and are they reliable?
Risen provides two warranties: a 15-year product warranty covering material and manufacturing defects, and a 30-year linear power warranty - a premium standard for commercial-grade bifacial modules. Risen Energy holds Tier 1 status, confirming the financial stability of the warrantor and the long-term credibility of its commitments. This matters particularly for utility-scale PV projects with multi-year bank financing.
Is the bifaciality of the Risen RSM110-8-BHDG panels actually worth it in real-world conditions?
Yes, when the installation is properly designed. The RSM110-8-BHDG series has a bifaciality factor of 85±10%, meaning the rear side can generate up to 85% of the front-side output from ground-reflected irradiance. Snow-covered ground in winter reflects sunlight intensively and noticeably boosts yield. On ground-mounted systems with light-colored gravel or white membranes, the bifacial gain can deliver an additional 5-15% of annual energy output.
Can the Risen TITAN RSM110-8-BHDG panels withstand heavy snow loads and strong winds?
Yes. The RSM110-8-BHDG series is certified for snow loads up to 5,400 Pa and wind loads up to 2,400 Pa. The Dual Glass construction - replacing a conventional polymer backsheet - adds structural rigidity and eliminates backsheet cracking risk from long-term thermal cycling. This is a key advantage in locations exposed to heavy snowfall, high winds, or significant seasonal temperature swings.
What is the maximum power output of the Risen RSM110-8-BHDG and which type of installation is it designed for?
The RSM110-8-BHDG series reaches up to 600 Wp under Standard Test Conditions (STC). The large 210 mm wafer cells and 2384×1096 mm module dimensions reduce the number of modules per MW, lowering BoS (Balance of System) costs and improving the LCOE of the entire plant. The series primarily targets large commercial installations and utility-scale PV farms, but also suits expansive industrial rooftops and warehouse facilities.
How do the Risen TITAN RSM110-8-BHDG panels perform during heat waves - do they lose significant power output?
Thanks to HJT technology, the RSM110-8-BHDG series has a power temperature coefficient of just -0.24%/°C. At a typical cell temperature of 65°C (40°C above STC), the module loses only about 9.6% of its rated power - compared to roughly 14% for a standard PERC module. On hot summer days, these HJT modules clearly outperform PERC in real-world energy yield and output stability.
