The Risen TITAN RSM120-6-BHDG series represents an advanced solution in the Bifacial Dual Glass module segment, redefining performance standards in harsh environmental conditions. Thanks to the use of double glass and multi-busbar (MBB) technology cells, these panels minimize losses resulting from micro-cracks and provide exceptional resistance to potential-induced degradation. A key differentiator of the series is its ability to generate energy from both sides of the module, which, combined with a low temperature coefficient, translates into a significantly higher annual yield compared to standard monofacial units. The use of half-cut cell technology allows for efficient operation even in partial shading, solving the problem of power drops in densely built-up areas or on farms with specific terrain features. This solution is primarily dedicated to investors seeking maximum durability and the lowest cost of energy (LCOE) in the long term. The robust glass-glass construction protects components from moisture and ammonia, making these panels an ideal choice for agricultural and ground-mounted installations with high albedo. By choosing the TITAN series, you gain increased mechanical resistance and the assurance of stable system operation for decades, putting this product a step ahead of traditional backsheet solutions.

About the TITAN RSM120-6-BHDG series

6 answered

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

Is the Risen TITAN RSM120-6-BHDG series still available for purchase?

The Risen TITAN RSM120-6-BHDG series has been discontinued and is no longer in regular production at most distributors. Limited warehouse stock may still exist at select suppliers, but consistent supply should not be expected. We recommend confirming availability directly with your local dealer and considering current Risen Energy alternatives with comparable technical specifications.

What warranty does the Risen TITAN RSM120-6-BHDG come with?

Risen Energy provides a 15-year product warranty covering material defects and workmanship, along with a 30-year linear power output warranty. After 30 years of operation, the modules are guaranteed to retain at least 80.6% of their nominal power output. This extended warranty horizon is made possible by the glass-glass construction, which eliminates the moisture-driven degradation typical of backsheet-based modules.

What does Bifacial Dual Glass mean in the TITAN RSM120-6-BHDG, and how much additional energy can it generate?

Bifacial Dual Glass means the module uses tempered glass on both sides instead of a polymer backsheet, enabling power generation from both direct front-side irradiance and reflected rear-side irradiance. On ground-mounted systems with high-albedo surfaces or agrivoltaic setups, rear-side energy gain typically ranges from 5 to 20% annually, directly reducing the overall system LCOE compared to standard monofacial modules.

Are the TITAN RSM120-6-BHDG panels suitable for agricultural or agrivoltaic installations?

Yes, this series is exceptionally well-suited for agricultural environments. The glass-glass construction provides strong resistance to ammonia, moisture, and crop-protection chemicals that rapidly degrade standard backsheet materials. The bifacial design additionally captures energy reflected from soil or crops. Combined with the 30-year power warranty, these features make the series a low-risk choice for long-term ground-mounted farm projects.

How does HJT cell technology in the Risen TITAN RSM120-6-BHDG affect performance on hot days?

HJT cells feature a lower temperature coefficient than standard PERC cells, meaning the modules lose less output power when ambient temperatures exceed 25°C. In practice, HJT modules produce more energy during hot summer afternoons than comparably rated PERC modules with the same nominal wattage. This advantage is especially significant in ground-mounted installations that receive direct full-sun exposure for many hours per day.

Do the 360 Wp Risen TITAN RSM120-6-BHDG panels perform well under partial shading?

Thanks to half-cut cell technology, the TITAN RSM120-6-BHDG series is significantly more resilient to power losses from partial shading than conventional 60-cell modules. Splitting each cell in half reduces resistive losses and limits the impact of shaded cells to only half the electrical string. The 360 Wp rated power combined with this design makes the series well-suited for sites with irregular terrain or obstructions causing intermittent shading.
