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. - **Double-Glass Construction: 5,400 Pa Snow Load, 2,400 Pa Wind Load** - 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. - **Confirmed Tier-1 BNEF Status – Q1 and Q4 2025** - 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. - **Up to 22.84% Efficiency – Competitive with Leading Peer Comparables** - 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. - **30-Year Linear Power Warranty – 87.4% Retained After 30 Years** - 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. ## Cons - **~32 kg Weight – Roof Structural Requirements** - 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. - **15–16 Year Product Warranty Below Best-in-Class** - 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. ## About this series 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. ## Notable figures - At 22.6% efficiency, this panel is on par with typical \*\*TOPCon 550-600W\*\* modules - Power density of 226.5 W/m² matches the \*\*TOPCon 550-600W\*\* median - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 550-600W\*\* median - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces - Ranked #3522 out of 14005 panels for efficiency in the database ## Questions ### Do the DAH Solar DHN-72X16/DG(BW) panels perform well under low-irradiance conditions typical of Poland? Yes. The N-type TOPCon cell technology used in the DHN-72X16/DG(BW) series features a lower temperature coefficient (-0.29%/°C) and superior performance under diffuse light compared to older PERC cells. This means the module generates more energy on overcast days and during sunrise and sunset periods — conditions that characterize the Polish climate for the majority of the year. ### What does it mean that the DHN-72X16/DG(BW) series is bifacial, and is the premium worth paying? Bifacial means the panel generates electricity from both its front and rear surfaces by capturing light reflected from the ground or rooftop substrate. On light-colored surfaces — such as a white roofing membrane or snow cover — energy yield can increase by several percent. This is particularly advantageous in utility-scale PV farms mounted on elevated racking structures, but also delivers measurable gains on rooftops with a reflective substrate. ### What warranty is provided for the DAH Solar DHN-72X16/DG(BW) panels? The DHN-72X16/DG(BW) series comes with a 16-year product warranty covering material and manufacturing defects, as well as a 30-year linear power output warranty. After 30 years of operation, the module is guaranteed to retain at least 87.4% of its rated nominal power. DAH Solar holds Bloomberg Tier 1 manufacturer status, which further substantiates the credibility of these warranty commitments. ### Why does the DHN-72X16/DG(BW) series feature a double-glass construction, and what does this mean for the long-term reliability of the installation? The double-glass construction replaces the conventional rear backsheet with a second pane of tempered glass, significantly improving the module's resistance to moisture ingress, wide temperature fluctuations, and mechanical stress. The panel is rated to withstand snow loads of up to 5,400 Pa and wind loads of up to 2,400 Pa. In the Polish climate — characterized by heavy snowfall in winter and variable temperatures — this translates to a substantially reduced risk of delamination and a longer service life for the overall installation. ### How much does the DAH Solar DHN-72X16/DG(BW) panel weigh, and can a typical residential roof support such an installation? The DHN-72X16/DG(BW) module weighs approximately 31–32 kg and measures 2,279 × 1,134 × 30 mm. It is larger and heavier than standard 400–430 W modules, so a structural load-bearing assessment of the roof is advisable before installation — particularly on older timber-framed structures. The installer should select appropriate mounting rails and inspect the condition of the roof truss. On new or reinforced roofs, installation presents no structural concerns. ### What module efficiency do the DAH Solar DHN-72X16/DG(BW) panels offer, and how does that compare to other models in this power class? The DHN-72X16/DG(BW) series achieves module efficiency of approximately 22.25–22.44%, which is an excellent result for panels rated up to 590 Wp. By comparison, mainstream PERC cells typically deliver 20–21% efficiency. The higher efficiency means that a greater amount of energy can be harvested from the same roof area — a critical advantage when available mounting space is limited. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/en-dhn-72x16-dg-bw-575-590w-5a427c4d3df1.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.2 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -30 W, lighter, +2.0 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +50 W, lighter, +2.0 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +45 W, cooler, +1.8 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | -35 W, lighter, +1.8 pp | | [DAH Solar DHM-72X10-540W](https://comparepv.com/panel/dah-dhm-72x10-540w) | 540 W | Hotter, -1.8 pp, -5 yr warranty | | [DAH Solar DHM-T72X10/FS-545W](https://comparepv.com/panel/dah-dhm-t72x10-fs-545w) | 545 W | Hotter, -1.6 pp, -5 yr warranty | | [DAH Solar DHM-T72X10/FS-550W](https://comparepv.com/panel/dah-dhm-t72x10-fs-550w) | 550 W | Hotter, -1.4 pp, -5 yr warranty | | [DAH Solar DHM-72X10-555W](https://comparepv.com/panel/dah-dhm-72x10-555w) | 555 W | Hotter, -1.2 pp, -5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +65 W, lighter, +2.6 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +60 W, lighter, +2.4 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +55 W, lighter, +2.2 pp | --- Source: https://comparepv.com/panel/dah-dhn-72x16-dg-bw-585 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.
