Risen TITAN RSM132-6-HDGB modules represent a breakthrough in energy efficiency thanks to the use of advanced bifacial technology, which enables additional energy generation from both sides of the panel. The use of an innovative double glass design ensures the highest resistance to PID degradation and extreme weather conditions, which directly translates into a significantly longer lifespan for the entire installation. This series is based on large-format cells, which, combined with a dense multi-busbar interconnect grid, significantly reduces resistive losses and minimizes the risk of harmful micro-cracks. Thanks to an exceptionally low temperature coefficient, these panels maintain high efficiency even during intense sunlight, effectively solving the common problem of power drops during the summer period. This solution is primarily dedicated to professional solar farms and large commercial systems, where the investor-s key goal is to optimize LCOE costs and maximize yields from the available area. What sets this series apart from the competition is the unique combination of high power density with the reinforced mechanical stability of the glass-glass structure. Investing in the TITAN series is a guarantee of safety and financial predictability for the most demanding photovoltaic projects seeking technology that is fully resistant to the passage of time and changing environmental conditions.

About the TITAN RSM132-6-HDGB 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 RSM132-6-HDGB series still available for purchase?

The TITAN RSM132-6-HDGB series has been discontinued and is no longer actively manufactured by Risen Energy. Limited stock may still exist with certain distributors, but availability is uncertain and supply is not guaranteed. If you need HJT bifacial double-glass modules from Risen, it is worth asking about the current Hyper-ion series, which is the direct successor to this technology.

What warranty does the Risen TITAN RSM132-6-HDGB come with?

Risen provides a 15-year product warranty covering manufacturing defects and a 30-year linear power output warranty. The double-glass construction minimizes degradation - after 30 years, the module is expected to retain at least 87.4% of its nominal output. This is among the longest power warranties available in the market for any module class.

How does the HJT technology in the RSM132-6-HDGB differ from standard PERC modules?

HJT cells combine an N-type crystalline silicon substrate with thin amorphous silicon layers, typically achieving cell efficiency above 24%, while conventional PERC relies on P-type substrates and reaches roughly 21-22%. The most important practical difference is the temperature coefficient: HJT sits around -0.24% /°C versus -0.35% /°C for PERC, meaning significantly lower power losses during hot summer days under intense irradiance.

Do the RSM132-6-HDGB bifacial modules actually generate more energy, and under what conditions?

Yes - bifacial design allows the rear glass to pass diffuse and reflected light to the back side of the HJT cells. Real-world bifacial gain typically ranges from 5% to 15% depending on ground albedo: light-colored gravel or concrete delivers the highest gains, while dark soil or grass produces lower ones. For utility-scale solar farms with optimized mounting height, the additional yield meaningfully improves LCOE.

Why do the RSM132-6-HDGB modules use a double-glass construction instead of a standard backsheet?

The rear glass replaces the polymer backsheet, which yellows and degrades over time due to UV exposure and moisture ingress. Double-glass construction virtually eliminates PID degradation risk, improves mechanical durability - the modules are rated for snow loads up to 5400 Pa and wind loads up to 2400 Pa - and extends the realistic service life beyond 30 years, directly supporting the 30-year power warranty.

Are Risen TITAN RSM132-6-HDGB panels rated at 390 Wp suitable for large commercial systems and solar farms?

The TITAN RSM132-6-HDGB at 390 Wp was specifically designed for large commercial and utility-scale applications. The HJT bifacial technology in the 132-cell format delivers high power density per square meter, reducing LCOE through lower BoS, mounting, and wiring costs per unit of energy. On solar farms with high-albedo ground cover, the bifacial gain further improves the return on investment.
