The ~1.7 percentage-point advantage over Talesun translates into measurably higher energy yield from the same roof or ground area. - **Low TOPCon Temperature Coefficient** - The Pmax temperature coefficient of -0.31%/°C compares favorably to the typical -0.35–0.37%/°C of PERC technology. Under Polish summer conditions—with module temperatures reaching ~65°C—this results in approximately 1–1.5% lower power losses than comparable PERC modules. - **Degradation ≤0.4%/year and 30-Year Linear Power Warranty** - The manufacturer guarantees ≤1% first-year degradation (LID) and ≤0.4%/year over the subsequent 29 years, retaining ≥87.4% of rated power after 30 years. Kiwa PVEL has confirmed the series' resilience across thermal cycling, PID, and LID+LETID test sequences in its 2025 Reliability Scorecard. - **BNEF Tier 1 (Q3 2025) and Kiwa PVEL Top Performer 2025** - DMEGC has maintained BNEF Tier 1 status for six consecutive years (confirmed Q3 2025) and is listed by both S&P and SMM. The Kiwa PVEL Top Performer 2025 designation—awarded following independent stress testing—effectively eliminates the bankability risk associated with smaller manufacturers. - **Bifacial Glass-Glass with Up to +25% Rear-Side Gain** - The glass-glass construction with bifacial cells enables up to 25% additional energy harvest from reflected irradiance on high-albedo surfaces such as gravel, white roofing membranes, or snow. Compared to monofacial equivalents, real-world annual energy yield is 5–15% higher depending on the installation configuration. ## Cons - **Product Warranty Limited to 15 Years** - At 15 years, the product warranty falls short of premium competitors offering 25-year coverage—such as the Jinko Tiger Neo and LONGi Hi-MO 6. In the utility-scale PV and C&I segments, where financing agreements and insurance policies frequently require a 20–25-year product warranty, this limitation may complicate project bankability. ## About this series The DMEGC DMxXXM10T-B72HSW series are modules designed for maximum yield from the same surface area, especially where fast returns and stable performance over years are crucial. The use of **n-type TOPCon** cells minimizes typical losses found in older technologies and maintains high efficiency even under weaker sunlight. The **bifacial glass-glass** construction supports an additional gain from reflected radiation, which genuinely helps on light-colored roofs, aggregate ground, or on installations on east-west facades. Thanks to the **144 half-cut** format, the modules handle partial shading better and offer more stable performance under uneven row illumination. In practice, this series solves the problem of limited surface area and increases investment profitability without complicating the design. This is an excellent choice for utility-scale PV farms, large commercial & industrial (C&I) rooftops, and installations requiring weather resistance and long-term reliability - where competitive monofacial panels fail to utilize the surrounding potential. ## Notable figures - At 23.0% efficiency, this panel is 0.6pp above typical \*\*TOPCon 550-600W\*\* modules (median: 22.4%) - 230.3 W/m² power density - 5.9 W/m² more than \*\*TOPCon 550-600W\*\* median (224.4 W/m²), more power per roof area - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 550-600W\*\* panels - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface - Ranked #1919 out of 14005 panels for efficiency in the database ## Questions ### What warranty is provided for the DMEGC DMxxxM10T-B72HSW panels, and what does it exactly cover? The DMEGC DMxxxM10T-B72HSW series comes with a 15-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty. The manufacturer guarantees that after 30 years the module will retain at least 87.4% of its nominal power. This is one of the longest warranty periods currently available on the market and is a critical factor when calculating the return on investment for a utility-scale PV plant or an industrial installation. ### Do the DMEGC DMxxxM10T-B72HSW modules perform well under low-irradiance conditions and on overcast days? Yes. The n-type TOPCon cells used in this series feature a low temperature coefficient (approx. -0.29%/°C) and superior response to diffuse irradiance compared to older PERC modules. In practical terms, this translates into higher energy yield on cloudy days and during early morning or late afternoon hours, resulting in measurably more kilowatt-hours generated annually for the same nominal power rating. ### What is the bifacial glass-glass construction in the DMxxxM10T-B72HSW series, and when does it truly pay off? Bifacial glass-glass means the module features two glass panes instead of a rear backsheet, enabling it to generate power from both the front and rear sides by capturing irradiance reflected from the ground surface (albedo). The greatest bifacial gain is achieved on high-albedo substrates such as gravel, light-colored roofing membranes, and snow, as well as in east-west racking configurations. The all-glass encapsulation also provides enhanced resistance to moisture ingress and ammonia exposure, extending the module's service life. ### What is the maximum power output of the DMEGC DMxxxM10T-B72HSW module, and what types of installations is it designed for? The series covers modules up to 600 Wp under STC conditions. The 144 half-cut cell format in a 2278×1134 mm form factor makes this series primarily suited for large-scale applications: utility-scale PV farms, industrial rooftops, and commercial & industrial (C&I) facilities. The high per-module power rating reduces the total number of modules required per installation, thereby lowering balance-of-system (BoS) costs including structural and cabling expenses. ### How do the n-type TOPCon cells in the DMEGC DMxxxM10T-B72HSW differ from mainstream PERC modules? TOPCon (Tunnel Oxide Passivated Contact) technology based on n-type silicon achieves higher cell efficiency than PERC — approximately 22–23% versus 20–21% — and exhibits significantly lower first-year degradation as well as reduced susceptibility to LID (Light Induced Degradation). This results in higher energy yield throughout the entire system lifetime and more stable performance over subsequent decades of operation. ### Is DMEGC a reputable PV manufacturer, and is the DMxxxM10T-B72HSW series a trustworthy investment? DMEGC (Dongguan Meike Electric Co.) is a Chinese manufacturer listed on the Bloomberg NEF Tier 1 ranking, which confirms its verified financial capacity to honor long-term warranty obligations. The company holds IEC and TÜV certifications for its modules. Tier 1 status is a prerequisite for securing project finance for PV installations and provides investors with an additional layer of protection when pursuing warranty claims. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/66b9d5f8645d5-c9315c1b69a5.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +50 W, lighter, +2.0 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -35 W, lighter, +1.8 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +45 W, lighter, +1.8 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -40 W, lighter, +1.6 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +40 W, lighter, +1.6 pp | | [DMEGC GH285M10T-B36HST](https://comparepv.com/panel/hengdian-group-dmegc-magnetics-co-ltd-dmegc-solar-gh285m10t-b36hst) | 285 W | -310 W, -12.0 pp | | [DMEGC GH290M10T-B36HST](https://comparepv.com/panel/hengdian-group-dmegc-magnetics-co-ltd-dmegc-solar-gh290m10t-b36hst) | 290 W | -305 W, -11.8 pp | | [DMEGC GH295M10T-B36HST](https://comparepv.com/panel/hengdian-group-dmegc-magnetics-co-ltd-dmegc-solar-gh295m10t-b36hst) | 295 W | -300 W, -11.6 pp | | [DMEGC GH300M10T-B36HST](https://comparepv.com/panel/hengdian-group-dmegc-magnetics-co-ltd-dmegc-solar-gh300m10t-b36hst) | 300 W | -295 W, -11.4 pp | | [DMEGC GH400M10T-B48HST-385](https://comparepv.com/panel/hengdian-group-dmegc-magnetics-co-ltd-dmegc-solar-gh400m10t-b48hst-385) | 385 W | -210 W, -8.1 pp | | [DMEGC GH400M10T-B48HST-390](https://comparepv.com/panel/hengdian-group-dmegc-magnetics-co-ltd-dmegc-solar-gh400m10t-b48hst-390) | 390 W | -205 W, -7.9 pp | | [DMEGC GH400M10T-B48HST-395](https://comparepv.com/panel/hengdian-group-dmegc-magnetics-co-ltd-dmegc-solar-gh400m10t-b48hst-395) | 395 W | -200 W, -7.7 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +55 W, lighter, +2.2 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +35 W, cooler, +1.4 pp | --- Source: https://comparepv.com/panel/dmegc-hengdian-group-dmegc-magnetics-co-ltd-dm595m10t-b72hsw 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.
