The double-sided **bifacial** design allows for the absorption of radiation from both the front and the back of the module - which translates into a real increase in energy yield, especially when installed above light surfaces or in ground-mounted systems. The **glass-glass** (glass-glass) construction, instead of the traditional backsheet, extends the lifespan of the panel and increases its resistance to moisture and UV radiation, which is crucial in the Polish climate with large temperature fluctuations. The series also features **excellent temperature coefficients** - power losses at high temperatures are significantly lower than in older technologies, which is particularly important during the summer months. The full black version, with a black frame and black glass, is ideal for rooftop installations, where aesthetics are important - on residential roofs, office buildings, and carport canopies. This solution is suitable for both consumers seeking high quality at a reasonable price, and professional installers implementing larger commercial projects. ## Notable figures - At 23.0% efficiency, this panel is on par with typical \*\*TOPCon 450-500W\*\* modules - Power density of 230.4 W/m² packs 5.2 W/m² more into the same footprint vs \*\*TOPCon 450-500W\*\* median (225.2 W/m²) - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 450-500W\*\* median - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface - In the top 14% for efficiency among all TOPCon panels ## Questions ### What sets the TOPCon technology in Sun Earth DXM8-54HBG panels apart from PERC cells? The N-type TOPCon cells used in the DXM8-54HBG series deliver a lower temperature coefficient and higher conversion efficiency than PERC cells. This means smaller power losses on hot days and a higher annual energy yield. TOPCon also performs better under low-irradiance conditions — early morning, late evening, and overcast skies — which is a real advantage in central European climates. ### What warranty does the Sun Earth DXM8-54HBG carry, and how does it compare to the competition? The DXM8-54HBG series comes with an exceptionally long 40-year product warranty and a 40-year linear power output warranty. This is among the longest warranty periods available in the solar panel market. The manufacturer's confidence stems directly from the durability of the glass-glass construction and the inherently slower degradation rate of N-type TOPCon cells compared to older technologies. ### Do the bifacial DXM8-54HBG panels actually produce more power, and when is the gain largest? Yes. The bifacial design allows the rear side to absorb light reflected from the ground, boosting energy yield by up to 10–15% compared to a conventional single-sided module. The effect is most pronounced over bright surfaces — concrete, gravel, or snow — and in ground-mounted systems with adequate clearance beneath the array. On dark rooftop surfaces, the bifacial gain is noticeably smaller. ### Is the full black version of the Sun Earth DXM8-54HBG a good fit for a sloped residential rooftop? Yes, the full black variant — featuring a black frame and black glass — is designed specifically for that use case. It blends seamlessly into dark roof coverings without disrupting the home's appearance. With up to 455 W per panel in a compact form factor, it makes efficient use of available roof space. The modules are equally well suited for office buildings and carport canopies. ### Why does the Sun Earth DXM8-54HBG use glass-glass construction instead of a traditional polymer backsheet? Dual glass — two glass sheets instead of glass plus a backsheet film — provides significantly better protection against moisture ingress, UV radiation, and thermal stress. In climates with large seasonal temperature swings, traditional backsheets can degrade over time. The glass-glass build eliminates that risk, extends module lifespan, and is the primary reason the manufacturer backs the DXM8-54HBG with a 40-year warranty. ### Which inverter should be paired with the 455 W Sun Earth DXM8-54HBG panel? The DXM8-54HBG 455 W module is compatible with standard string inverters available on the market — including SMA, Fronius, Huawei, and GoodWe — provided the inverter's MPPT input voltage range covers the planned string voltage. When sizing the string, your installer should verify the panel's Voc and Isc values from the official datasheet to ensure safe and efficient operation. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/aid-18301284-1aca984a51a5.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +45 W, +1.8 pp, -10 yr warranty | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +40 W, +1.5 pp, -10 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +50 W, +1.5 pp, -10 yr warranty | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +50 W, +1.5 pp, -10 yr warranty | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +50 W, +1.5 pp, -10 yr warranty | | [GCL GCL-NR10R/54BGDF](https://comparepv.com/panel/gcl-gcl-nr10r-54bgdf) | 500 W | +50 W, +1.5 pp, -10 yr warranty | | [Sun Earth SKT390M10](https://comparepv.com/panel/sun-earth-skt390m10) | 390 W | -60 W, -3.0 pp, -15 yr warranty | | [Sun Earth DXM8-54HBG-420](https://comparepv.com/panel/sun-earth-dxm8-54hbg-420) | 420 W | -30 W, -1.5 pp | | [Sun Earth DXM8-54HBG-430](https://comparepv.com/panel/sun-earth-dxm8-54hbg-430) | 430 W | -20 W, -1.0 pp | | [Sun Earth DXM8-54HBG-435](https://comparepv.com/panel/sun-earth-dxm8-54hbg-435) | 435 W | -15 W, -0.7 pp | | [Sun Earth DXM8-54HBG-440](https://comparepv.com/panel/sun-earth-dxm8-54hbg-440) | 440 W | -10 W, -0.5 pp | | [Sun Earth DXM8-54HBG-455](https://comparepv.com/panel/sun-earth-dxm8-54hbg-455) | 455 W | +0.3 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +60 W, +2.0 pp, -10 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +55 W, +1.7 pp, -10 yr warranty | --- Source: https://comparepv.com/panel/sun-earth-dxm8-54hbg-450 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.
