DMEGC announced in 2026 a further evolution of the Greenhouse line based on the G12RT cell, offering a transmittance range of 2–50%. - **Low Temperature Coefficient — N-Type Advantage** - N-type TOPCon cells deliver a Pmax temperature coefficient of -0.29%/°C, a clear improvement over PERC technology (~-0.35%/°C). In greenhouse installations where module temperatures regularly exceed 50°C, this difference translates into measurably higher seasonal energy yield. - **30-Year Power Warranty with 87.4% Retention** - The manufacturer guarantees at least 87.4% of rated power output after 30 years of operation, a performance level on par with the best offerings currently available on the market. The product warranty stands at 15 years — standard for the Tier-1 agri-PV segment. - **BNEF Tier-1 Manufacturer (Confirmed Q3 2025)** - DMEGC Solar maintains BloombergNEF Tier-1 status, confirming bankability of projects using these modules for non-recourse financing. For C&I projects and agri-PV farms requiring external project finance, this is a critical eligibility criterion. - **IP68 + Half-Cut: Operational Resilience** - The IP68-rated junction box protects against prolonged water immersion — a meaningful advantage in crops with intensive irrigation systems and spray applications. The half-cut cell layout reduces mismatch losses under partial shading from mounting structures and plant rows, a condition typical of row-based agri-PV installations. ## Cons - **Lower Front-Side Efficiency vs. Standard N-Type Modules** - Module efficiency ranges from 18.58–19.16%, while comparable N-type peers without agri-PV functionality (Solarspace SS8-60HD, Seraphim YUKON N, Resun RS8K-M) achieve 22.87–22.94%. The ~3.7–4.4 percentage point gap is an inherent result of the light transmittance design required for crop growth; however, for installations where light transmission is not required, it represents a genuine reduction in energy yield per m² of rooftop or ground area. ## About this series The DMEGC GHxXXM10T-B60HST series was designed for demanding agri-PV and greenhouse installations, where performance isn’t measured only by yield, but also by stability in harsh environments. These modules are built on **N-type monocrystalline cell architecture**, which helps minimize typical performance losses over time and ensures predictable energy production across multiple seasons. The application of **half-cut cell technology** enhances resistance to micro-cracking and reduces losses during partial shading-common under coverings, with load-bearing structures, or in row layouts. In practice, this series addresses yield fluctuations at high temperatures and uneven lighting conditions, offering **superior thermal performance** and better operation in low-light scenarios. An additional advantage is the **high enclosure sealing (IP68)**, crucial for protection against moisture, splashing water, and dust. ## Notable figures - Efficiency of 18.6% is 3.9pp below the \*\*N-type 450-500W\*\* median (22.5%) - Power density of 185.8 W/m² is 39.4 W/m² below \*\*N-type 450-500W\*\* median (225.2 W/m²) - needs more roof space - At -0.29%/°C, hot weather performance is typical for \*\*N-type 450-500W\*\* panels - At 32.0 kg, this panel is 8.3 kg heavier than the \*\*N-type 450-500W\*\* median (23.7 kg) - more demanding for installation crews - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof ## Questions ### Why is the DMEGC GHxxxM10T-B60HST series specifically designed for agri-PV and greenhouse installations? The GHxxxM10T-B60HST series combines several features critical for agricultural photovoltaic applications: N-type TOPCon cells in a half-cut configuration minimize mismatch losses caused by non-uniform shading from support structures and films; the bifacial design enables energy harvest from light reflected off the ground or vegetation; and the IP68-rated junction box provides full protection against moisture, pesticide spray, and dust accumulation typical of agricultural environments. ### What warranty coverage do the DMEGC GHxxxM10T-B60HST panels carry? The manufacturer provides a 15-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty guaranteeing a minimum of 87.4% of nominal power at the end of the warranty period. In practical terms, a 495 Wp module should still deliver at least approximately 433 Wp after 30 years of operation. ### Do the DMEGC GHxxxM10T-B60HST panels perform well during summer at elevated temperatures? Yes. N-type cell technology exhibits a lower temperature sensitivity than conventional P-type cells. The temperature coefficient of Pmax for this series is approximately -0.29%/°C — a favorable figure that translates into meaningfully higher energy yield on hot days compared to older cell technologies. ### What is the maximum power output of the DMEGC GHxxxM10T-B60HST module and how many cells does it contain? The top model in the series achieves a peak power output of 495 Wp at a module efficiency of up to 19.16%. The module comprises 120 N-type monocrystalline half-cut cells and has overall dimensions of approximately 2278 × 1134 mm, with a weight of 32 kg. ### What practical benefit does the bifacial design of the DMEGC GHxxxM10T-B60HST panels offer in agricultural settings? Bifaciality means the rear glass of the module also generates power from reflected irradiance. In agri-PV and greenhouse installations, where modules are mounted on elevated structures, reflections from bright ground surfaces, mulch films, or concrete slabs can increase real-world energy yield by several to over ten percent, depending on the tilt angle and the albedo of the surrounding surfaces. ### Are the DMEGC GHxxxM10T-B60HST panels resistant to moisture and plant protection products used in greenhouses? Yes. The GHxxxM10T-B60HST series is equipped with an IP68-rated junction box, providing complete ingress protection against water even under temporary submersion. The glass-glass construction additionally shields the laminate from water vapor, chemical agents, and corrosion — a particularly important attribute in greenhouse environments where humidity and agrochemical exposure are continuous. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/6708d58bc42cc-dbacfe243067.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +6.4 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +6.2 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +6.1 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +5.9 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +5.9 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | Cooler, lighter, +5.9 pp | | [DMEGC GH285M10T-B36HST](https://comparepv.com/panel/hengdian-group-dmegc-magnetics-co-ltd-dmegc-solar-gh285m10t-b36hst) | 285 W | -195 W, lighter, -7.5 pp | | [DMEGC GH290M10T-B36HST](https://comparepv.com/panel/hengdian-group-dmegc-magnetics-co-ltd-dmegc-solar-gh290m10t-b36hst) | 290 W | -190 W, lighter, -7.3 pp | | [DMEGC GH295M10T-B36HST](https://comparepv.com/panel/hengdian-group-dmegc-magnetics-co-ltd-dmegc-solar-gh295m10t-b36hst) | 295 W | -185 W, lighter, -7.2 pp | | [DMEGC GH300M10T-B36HST](https://comparepv.com/panel/hengdian-group-dmegc-magnetics-co-ltd-dmegc-solar-gh300m10t-b36hst) | 300 W | -180 W, lighter, -7.0 pp | | [DMEGC GH400M10T-B48HST-385](https://comparepv.com/panel/hengdian-group-dmegc-magnetics-co-ltd-dmegc-solar-gh400m10t-b48hst-385) | 385 W | -95 W, -3.7 pp | | [DMEGC GH400M10T-B48HST-390](https://comparepv.com/panel/hengdian-group-dmegc-magnetics-co-ltd-dmegc-solar-gh400m10t-b48hst-390) | 390 W | -90 W, -3.5 pp | | [DMEGC GH400M10T-B48HST-395](https://comparepv.com/panel/hengdian-group-dmegc-magnetics-co-ltd-dmegc-solar-gh400m10t-b48hst-395) | 395 W | -85 W, -3.3 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +170 W, lighter, +6.6 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +165 W, lighter, +6.4 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +160 W, lighter, +6.2 pp | --- Source: https://comparepv.com/panel/hengdian-group-dmegc-magnetics-co-ltd-gh480m10t-b60hst 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.
