Thanks to the use of a **glass-glass construction with bifacial energy generation**, these panels allow for significantly higher energy yields by effectively utilizing light reflected from the ground. This is a key improvement for investors seeking maximum self-consumption and a fast return on investment. This series stands out with an **exceptionally low temperature coefficient**, which guarantees stable operation and high power production even on the hottest days, when traditional modules lose efficiency. The compact design has been optimized for residential roofs and commercial installations, where limited space requires the use of components with the highest power density. These modules effectively solve the problem of installation aging by offering a **minimal annual performance degradation** of only 0.4 percent. A solid, double glass layer and a reinforced frame ensure resistance to extreme weather phenomena, while the elegant appearance makes the system blend perfectly with modern architecture. This is a product dedicated to demanding users who prioritize uncompromising durability and innovative silicon technology. ## Notable figures - Efficiency of 22.5% matches the \*\*TOPCon 450-500W\*\* median - Power density of 225.2 W/m² matches the \*\*TOPCon 450-500W\*\* median - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 450-500W\*\* panels - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof - In the top 30% for efficiency among all TOPCon panels ## Questions ### How does N-type TOPCon technology in TCL Zhonghuan HSM-ND48-GR435-455 panels differ from standard PERC cells? N-type TOPCon cells use an additional passivating contact layer that reduces carrier recombination and boosts efficiency compared to P-type PERC cells. In practice, this means higher power output from the same panel area, a lower annual degradation rate, and better performance at high temperatures, which translates into higher energy yields over the year. ### Are bifacial panels from the HSM-ND48-GR435-455 series worth it on a pitched residential roof? On a typical pitched roof, the bifacial gain is limited since the rear side has no access to reflected light from underneath. The biggest energy gain comes from flat roofs, ground-mount systems, or east-west arrays over a bright surface. Still, the glass-glass construction adds extra durability, so the panel performs well on pitched roofs too, just without fully utilizing the bifacial effect. ### What warranty does TCL Zhonghuan offer on the HSM-ND48-GR435-455 series panels? The manufacturer provides a 25-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. This means that even after 30 years of operation, the panel should still deliver a significant share of its rated power, making it one of the longer warranty periods currently available on the PV market. ### How low is the annual power degradation of the GR435-455 series and what does it mean for the investment? Annual degradation is just 0.4 percent, a notably better result than classic P-type panels, which often degrade at 0.5-0.7 percent per year. For a system owner, this means higher energy production sustained throughout the panel's lifetime and a better real return on investment over a 25-30 year horizon. ### Do TCL Zhonghuan HSM-ND48-GR435-455 panels perform well in summer, under high roof temperatures? Yes, this series features an exceptionally low temperature coefficient, so power losses as module temperature rises are smaller than in standard panels. In practice, on hot days when the panel heats up to 60-70 degrees Celsius, energy production drops less than it would with a conventional construction. ### Is choosing the 455 Wp variant of the HSM-ND48-GR series worthwhile for limited roof space? Yes, the up-to-455 Wp variant sits in the higher power class within this panel segment, delivering more energy from the same number of modules. This is especially beneficial when roof space is limited, as it increases the power density of the installation and allows a higher total system power without adding extra panels. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/68ff5174fed131e8cf2645ee_TCL-TC-435455-48-Wht-GG-Res-714eadb41025.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +45 W, lighter, +2.3 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +40 W, lighter, +2.0 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +50 W, cooler, +2.0 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +50 W, lighter, +2.0 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +50 W, lighter, +2.0 pp | | [GCL GCL-NR10R/54BGDF](https://comparepv.com/panel/gcl-gcl-nr10r-54bgdf) | 500 W | +50 W, cooler, +2.0 pp | | [TCL Zhonghuan HSM-ND48-GR435](https://comparepv.com/panel/tcl-zhonghuan-hsm-nd48-gr435) | 435 W | -15 W, -0.7 pp | | [TCL Zhonghuan HSM-ND48-GR440](https://comparepv.com/panel/tcl-zhonghuan-hsm-nd48-gr440) | 440 W | -10 W, -0.5 pp | | [TCL Zhonghuan HSM-BD54-LA445](https://comparepv.com/panel/tcl-zhonghuan-hsm-bd54-la445) | 445 W | Cooler, lighter | | [TCL Zhonghuan HSM-ND48-GR445](https://comparepv.com/panel/tcl-zhonghuan-hsm-nd48-gr445) | 445 W | Very close match | | [TCL Zhonghuan HSM-BD54-LA450](https://comparepv.com/panel/tcl-zhonghuan-hsm-bd54-la450) | 450 W | Cooler, lighter | | [TCL Zhonghuan HSM-BD54-LA455](https://comparepv.com/panel/tcl-zhonghuan-hsm-bd54-la455) | 455 W | Cooler, lighter, +0.3 pp | | [TCL Zhonghuan HSM-ND48-GR455](https://comparepv.com/panel/tcl-zhonghuan-hsm-nd48-gr455) | 455 W | +0.3 pp | | [TCL Zhonghuan HSM-BD54-WA460](https://comparepv.com/panel/tcl-zhonghuan-hsm-bd54-wa460) | 460 W | Cooler, lighter, +0.6 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +60 W, cooler, +2.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +55 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/tcl-zhonghuan-hsm-nd48-gr450 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.
