The Risen TITAN RSM144-6-BHDG series is an advanced solution based on large-format silicon wafers that redefines efficiency standards in large-scale solar projects. By utilizing bifacial dual-glass technology, these panels generate energy from both sides, which significantly increases total energy yield, especially in ground-mounted installations with light-colored ground. The glass-glass design provides exceptional resistance to potential-induced degradation and harsh weather conditions, translating into operational stability for decades. The use of half-cut cells minimizes internal losses and the risk of hot spots, directly addressing the issue of power drops during partial shading. This series stands out with a low temperature coefficient, which ensures that the modules maintain high efficiency even on hot days. It is a product dedicated to investors seeking to maximize profitability through LCOE reduction and the optimization of BOS system costs. Unlike standard modules, the TITAN RSM144-6-BHDG combines high power with precise current control, perfectly matching the requirements of modern inverters. It is the optimal choice for solar farms and large commercial installations where maximum power density per square meter is what matters.

About the TITAN RSM144-6-BHDG series

5 answered

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

Is the Risen TITAN RSM144-6-BHDG series still available for purchase?

The Risen TITAN RSM144-6-BHDG series has been discontinued and is no longer part of the manufacturer's active product lineup. If you need modules with comparable bifacial dual-glass HJT specifications, contact your distributor about current Risen alternatives. Availability may still vary depending on remaining distributor stock.

What is HJT technology in the Risen TITAN RSM144-6-BHDG, and is it worth the premium?

HJT (Heterojunction Technology) combines a crystalline silicon cell with thin amorphous silicon layers, yielding an exceptionally low temperature coefficient of approx. -0.24 %/°C. This means the panel loses far less power during hot weather than standard PERC modules. Combined with the bifacial design and up to 430 Wp output, HJT delivers a noticeably higher annual energy yield, making the premium price justifiable for projects targeting minimum LCOE.

What warranty does the Risen TITAN RSM144-6-BHDG series carry?

Risen provides a 15-year product warranty covering manufacturing defects and material failures. This is complemented by a 30-year linear power warranty guaranteeing a defined minimum output level over three decades of operation. This warranty scope is standard for Tier 1 premium-class modules and substantially reduces financial risk in long-term energy investments.

How much extra energy does the bifacial design of the RSM144-6-BHDG deliver compared to a standard monofacial panel?

Bifacial panels generate electricity from both sides, and with a reflective surface (white membrane, light soil, gravel, or snow) total energy yield can increase by 10-25% compared to a monofacial module. The gain is greatest in ground-mounted systems with an optimal tilt angle and high-albedo ground cover. The dual-glass construction also protects the rear surface and extends the module's mechanical durability.

Are the Risen TITAN RSM144-6-BHDG panels suitable for a large-scale solar farm?

Yes, the TITAN RSM144-6-BHDG series was designed primarily for large commercial installations and utility-scale solar farms. With up to 430 Wp per module and high power density, it helps cut BoS costs through fewer modules and less cabling per megawatt. Half-cut cells reduce power losses under partial shading, which is especially important on large arrays with trackers or uneven irradiation patterns.
