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. ## Notable figures - Efficiency of 20.6% is 1.6pp below the \*\*HJT 400-450W\*\* median (22.2%) - At 206.5 W/m², this panel generates 15.1 W/m² less per unit area than \*\*HJT 400-450W\*\* median (221.6 W/m²) - Temperature coefficient of -0.24%/°C matches the \*\*HJT 400-450W\*\* median - Weight of 35.0 kg is 12.0 kg above \*\*HJT 400-450W\*\* median (23.0 kg) - verify structural support - 85% bifaciality enables rear-side power generation, boosting yield by 4-13% on reflective surfaces ## Questions ### 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. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/18a91b4e377649f92d5645ffbd98b5d2-6dad69e6119e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Just Solar JST-EDMH-(445-465)W-TD (465W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-465w-class) | 465 W | Hotter, lighter, +3.2 pp | | [Luxor Solar LX-465M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-465m-182r-96-gg) | 465 W | +45 W, lighter, +3.2 pp | | [Maxeon SPR-MAX7-470](https://comparepv.com/panel/maxeon-spr-max7-470) | 470 W | Lighter, +3.1 pp, +10 yr warranty | | [AIKO AIKO-A470-MAH54Mb](https://comparepv.com/panel/aiko-aiko-a470-mah54mb) | 470 W | +50 W, lighter, +3.0 pp | | [AIKO AIKO-A460-MAH54Mb](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a460-mah54mb-1) | 460 W | Hotter, lighter, +3.0 pp | | [TCL Zhonghuan HSM-BD54-LA470](https://comparepv.com/panel/tcl-zhonghuan-hsm-bd54-la470) | 470 W | +50 W, lighter, +3.0 pp | | [Risen RSM144-6-415BHDG](https://comparepv.com/panel/risen-rsm144-6-415bhdg) | 415 W | -0.2 pp | | [Risen RSM144-6-425BHDG](https://comparepv.com/panel/risen-rsm144-6-425bhdg) | 425 W | +0.3 pp | | [Risen RSM144-6-430BHDG](https://comparepv.com/panel/risen-rsm144-6-430bhdg) | 430 W | +10 W, +0.5 pp | | [MY Solar MS480NC-HJTPBFT](https://comparepv.com/panel/my-solar-ms480nc-hjtpbft) | 480 W | +60 W, lighter, +1.5 pp | | [MY Solar MS475NC-HJTPBFT](https://comparepv.com/panel/my-solar-ms475nc-hjtpbft) | 475 W | +55 W, lighter, +1.3 pp | | [Lexron 430W](https://comparepv.com/panel/lexron-430w) | 430 W | Hotter, lighter, +1.0 pp | | [MY Solar MS470NC-HJTPBFT](https://comparepv.com/panel/my-solar-ms470nc-hjtpbft) | 470 W | +50 W, lighter, +1.0 pp | | [Longi Solar LR4-72HPH-465M](https://comparepv.com/panel/longi-lr4-72hph-465m) | 465 W | Hotter, lighter, -5 yr warranty | | [MY Solar MS465NC-HJTPBFT](https://comparepv.com/panel/my-solar-ms465nc-hjtpbft) | 465 W | +45 W, lighter, +0.8 pp | --- Source: https://comparepv.com/panel/risen-rsm144-6-420bhdg Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
