The DMEGC DMXXXM10T-72HSW/HBW photovoltaic panel series was designed for high energy output in the 72-cell format, popular in commercial installations and large rooftop/ground systems. The use of N-type TOPCon cells helps minimize typical power losses over time and improves energy yield under variable weather conditions, leading to a more predictable return on investment.

In practice, this series excels in real-world conditions: excellent performance at high temperatures supports stable generation during summer months, and mechanical durability facilitates design tailored to snow and wind requirements. The HSW and HBW construction variants allow selecting the module based on project priorities - from standard lightweight glass-film construction to long-lasting solutions.

This is the choice for companies, PV farms, and installers seeking to reduce LCOE without compromising on reliability and execution quality.

What owners get
N-type TOPCon Technology with Low Degradation

N-type TOPCon cells eliminate the LID/LeTID effects associated with older PERC technology. The manufacturer declares a degradation rate of ≤0.4%/year from year 2 onward and guarantees ≥87.4% of nominal power output after 30 years — on par with the best products in the segment.

Efficiency Up to 22.65% — Top of the Segment

The top-tier variant in the series reaches 22.65%, matching direct competitors such as the Hanersun Hitouch 5N HN18-72H (22.65%) and Q-SUN Qrystal N8 (22.65%). The series is fully competitive with its peers in terms of power density, which is critical when rooftop or ground-mount area is constrained.

30-Year Linear Power Output Warranty

The performance warranty spans 30 years with a guaranteed threshold of ≥87.4% at year 30. By comparison, the Risen RSM144-9-560-585BNDG offers only a 5-year product warranty — making DMEGC a more attractive choice for investors calculating LCOE over a 25–30 year horizon.

Tier 1 BNEF Status (Confirmed Q3 2025)

DMEGC Solar has maintained Tier 1 BloombergNEF status at least since Q3 2025, which directly facilitates securing non-recourse financing for utility-scale PV projects. The company has been in operation since 1980 and holds a manufacturing capacity exceeding 21 GW (BNEF Q2 2025 data).

Two Form-Factor Variants (HSW / HBW)

The series combines the HSW variant (standard appearance, glass-backsheet, lower weight) with the HBW variant (full-black, glass-backsheet) within a single product line, enabling installers to match the module to a project's aesthetic requirements without changing supplier.

Trade-offs
12-Year Product Warranty — Below Segment Standard

The Hanersun Hitouch 5N — covering the identical power range of 565–585 W at 22.65% efficiency — offers a 15-year product warranty. The shorter 12-year term may be a barrier in projects that require aligning the warranty period with the loan repayment schedule, typically 15 years for commercial installations.

Monofacial Only — No Rear-Side Energy Yield

Unlike direct peers — the Hanersun Hitouch 5N and Risen RSM144-9-560-585BNDG — the DMXXXM10T-72HSW/HBW series is strictly monofacial. In ground-mount installations on high-reflectivity surfaces (albedo ≥0.2), this forfeits potential rear-side energy yield estimated at 5–15% annually.

Common questions

6 answered
What warranty is offered on DMEGC DMXXXM10T-72HSW/HBW panels?
The manufacturer provides a 12-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty. This means the panel is guaranteed to retain a specified minimum percentage of its nominal power output over three decades. For a commercial-grade 72-cell format, a 30-year power warranty represents a solid industry standard that allows for confident return-on-investment planning in utility-scale PV farms and industrial installations.
What is the difference between the HSW and HBW variants in the DMXXXM10T-72 series?
The HSW variant features a conventional glass-backsheet construction: lighter and more cost-effective, sufficient for the majority of rooftop and ground-mounted installations. The HBW variant uses a dual-glass (glass-glass) construction: heavier, but significantly more resistant to moisture ingress, ammonia, and environmental stressors, which extends the module's service life. The HBW is the preferred choice where maximum longevity is the priority — for example, in utility-scale PV farms with long operational horizons.
Does the TOPCon technology in the DMXXXM10T-72 series actually reduce power degradation compared to older PERC panels?
Yes. N-type TOPCon cells exhibit a lower annual degradation rate than PERC cells. In practice, this means the panel retains more of its rated power after 10 or 15 years of operation than a comparable module based on older technology. TOPCon cells also perform better under diffuse light conditions, resulting in higher energy yields on overcast days — a meaningful advantage given the typical climate in Poland and Central Europe.
How do DMXXXM10T-72HSW/HBW panels perform in summer when rooftop or ground temperatures rise significantly?
N-type TOPCon cells have a more favorable temperature coefficient than P-type technologies, meaning they lose less power at elevated operating temperatures than legacy PERC modules. In summer, when a dark rooftop surface or concrete ballast foundation heats up to 60–70 °C, the difference can amount to several percentage points of daily energy yield. Over the course of a full year, this translates into a measurably higher total energy output.
What types of installations are DMEGC DMXXXM10T-72HSW/HBW panels rated up to 585 Wp best suited for?
The 72-cell format and peak power up to 585 Wp position this series squarely in the commercial and industrial segment. It is best suited for ground-mounted systems, utility-scale PV farms, large industrial rooftops such as warehouses and manufacturing halls, and prosumer systems above 30 kWp where module count carries logistical significance. For small residential installations up to 10 kWp, lighter 60-cell modules are generally the more practical choice.
Is DMEGC a reliable manufacturer, and do panels in this series carry the required certifications?
DMEGC (Hangzhou Dmegc Magnetics) is a Chinese manufacturer classified as a Tier 1 supplier by leading PV market research institutions, indicating verified financial capacity and stable, bankable production. Modules in the DMXXXM10T-72 series are certified to IEC 61215 and IEC 61730, which are mandatory for legal sale and grid connection in Poland and across the European Union. Tier 1 status also facilitates project financing, as lenders and banks typically require it as a prerequisite for approving PV project loans.
