Solid all-round for its segment
The DAH DHN-72X16/DG(BW) series are modules designed for high energy production under real-world conditions, even when weather in Poland is far from ideal. The use of N-type TOPCon cells ensures stable operation and better light utilization in low-sunlight conditions, which will be appreciated by installations on residential rooftops, corporate buildings, and small PV farms.
A key feature is the double-glass construction, which increases resistance to environmental factors and reduces the risk of material degradation over time. This allows the module to better withstand humidity, temperature fluctuations, and mechanical loads, such as heavy snowfall. In practice, this means fewer maintenance issues and more predictable operation of the installation.
The use of half-cut and multi-busbar architecture supports minimizing losses and improves tolerance to partial shading. This is a sensible choice for investors who expect durability, efficiency, and long-term profitability without compromising on any aspect.

Signals from the data
Residential, commercial, utility-scale, shaded-installations and hot-climate.
N-type TOPCon cells exhibit lower LID/LeTID degradation rates and a superior power temperature coefficient (typically -0.30%/°C vs. -0.35%/°C for PERC). In Poland's climate — characterized by frequent overcast conditions and elevated module temperatures in summer — this translates into measurably higher annual energy yield compared to legacy technology.
The certified mechanical ratings (5,400 Pa snow load, 2,400 Pa wind load per the ENF datasheet) place this series above the 4,000/2,400 Pa standard typical of backsheet modules. The absence of a polymer backsheet eliminates the risk of delamination blistering, PID, and moisture-induced degradation — a meaningful advantage given Poland's climate variability, with its wide temperature swings and significant precipitation.
DAH Solar has maintained BloombergNEF Tier-1 status continuously since at least Q1 2025, reconfirmed in Q4 2025 per the official BNEF list. This designation — awarded under a project financing threshold of ≥10 MW (raised in 2025) — ensures bankability with lenders and insurers while mitigating warranty risk associated with manufacturer insolvency.
The peak module efficiency of 22.84% is on par with the best models in the segment: AE Solar HORIZON CMD-144BDS (22.86%), Talesun TM7G72M (22.8%), and Horay Ocean (22.8%). This series matches the top offerings in the 575–590 Wp class while maintaining a clear advantage over PERC modules of equivalent power rating.
The manufacturer guarantees ≥87.4% of nominal power output after 30 years of operation. Against the backdrop of rising electricity prices in Poland, this directly supports revenue predictability across the full depreciation horizon. A 30-year linear power warranty is now the industry standard for premium double-glass modules.
The double-glass module weighs approximately 32 kg compared to 22–25 kg for typical backsheet modules of equivalent power class. This ~30–40% weight increase may require a structural assessment of the roof deck or the use of heavier-duty mounting rails, adding to BoS costs and complicating installations on older buildings.
The product warranty spans 15–16 years depending on the variant. Several N-type competitors — including Jinko Solar (Tiger Neo) and LONGi (Hi-MO 9) — offer 25-year product warranties on comparable modules. Over a 30-year operating horizon, this gap may be a material consideration for institutional investors and project finance lenders.
- Efficiency of 22.6% matches the TOPCon 550-600W median
- At 226.5 W/m² power density, roof space requirements are typical for TOPCon 550-600W panels
- At -0.29%/°C, hot weather performance is typical for TOPCon 550-600W panels
- Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof
- Ranked #3522 out of 14005 panels for efficiency in the database
