Under typical summer operating conditions (cell temperature 60–75°C), this translates to a real-world annual energy yield gain of 2–4% compared to legacy technology. - **30-Year Power Warranty (87.4%)** - The manufacturer guarantees at least 87.4% of nominal power output after 30 years of operation. Peer comparables — Talesun TM7G72M and Horay Solar HS 182-144 TC-D — do not publish an equally long warranty period, making the DAH DHN-72X16/DG(BB) particularly attractive for projects requiring long-term bankability. - **High Mechanical Strength — Double-Glass Construction** - The double-glass design is tested to withstand snow loads up to 5,400 Pa and wind loads up to 2,400 Pa — snow load ratings more than double the standard IEC requirements (2,400 Pa / 2,400 Pa). This makes the module especially well-suited for rooftop installations in high-snowfall or high-wind zones. - **80±5% Bifaciality — Meaningful Rear-Side Gains** - A bifaciality factor of 80±5% means that in installations over high-albedo surfaces (concrete, white roofing membrane, gravel ballast), the rear side of the module can contribute an additional 8–15% of annual energy yield, depending on ground albedo and mounting geometry. - **Confirmed BNEF Tier 1 Status** - DAH Solar has appeared continuously on BNEF's bankable manufacturers list from at least Q1 2025 through Q4 2025, facilitating project financing by banks and infrastructure funds while minimizing counterparty risk in long-term PV projects. ## Cons - **31.2 kg Weight — More Demanding Installation** - The double-glass construction weighs 31.2 kg, approximately 30–40% heavier than typical single-glass modules in the same power class (22–24 kg). In practice, this requires a two-person installation crew for every module and a more thorough structural assessment of the roof, both of which increase labor costs. ## About this series The DAH DHN-72X16/DG(BB) series are bidirectional modules with a glass-glass construction, designed for high energy production even when roof conditions are not ideal. The use of **N-type TOPCon cells** helps to minimize losses and maintain stable operation over a longer period, while **bidirectional generation** allows for the effective use of reflected light from a bright surface, such as a roof or carport surface. A key feature is the **double-glass construction**, which improves resistance to moisture and environmental factors, and increases the module's rigidity - this is important for installations exposed to wind and snow loads. The (BB) variant focuses on **all-black aesthetics**, making the series suitable for projects where a consistent appearance is important, from modern homes to commercial buildings. This is a good choice for installers and investors looking for modules that combine durability, better rear-side performance, and refined design. ## 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 - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface - In the top 25% for efficiency among all TOPCon panels ## Questions ### How does the DHN-72X16/DG(BB) variant differ from the standard version of this series? The (BB) designation stands for all-black — both the frame and the rear surface of the module are black, resulting in a uniform, aesthetically consistent installation appearance. The technical specifications remain identical to the BW version: N-type TOPCon cells, power output up to 590 Wp, and a glass-glass construction. This variant is the preferred choice for investors who prioritize a cohesive rooftop aesthetic — from modern single-family homes to high-profile commercial properties. ### What warranty is provided for DAH Solar DHN-72X16/DG(BB) panels? The manufacturer provides a 15-year product warranty and a 30-year power output warranty. After 30 years, the module is guaranteed to retain at least 87.4% of its nominal power output. This is among the longest warranties available on the market and is a direct result of the N-type TOPCon cell technology, which degrades significantly more slowly than older PERC-based technologies. ### Are the DAH Solar DHN-72X16/DG(BB) panels capable of handling heavy snow and wind loads typical in Poland? Yes. The DHN-72X16/DG(BB) series is certified for snow loads up to 5,400 Pa and wind loads up to 2,400 Pa. These values are sufficient even for the demanding conditions of Polish winters. Furthermore, the glass-glass construction enhances mechanical rigidity and moisture ingress resistance, which is particularly important for installations subject to prolonged snow accumulation. ### What is the temperature coefficient of these panels, and does it matter during summer? The temperature coefficient is -0.29%/°C, which is an excellent result. By comparison, mainstream PERC cells typically achieve -0.35%/°C. In practice, this means that on hot days when a panel heats up to 60–70°C, the DHN-72X16/DG(BB) modules lose less power than older-generation technologies. In the Polish climate, this translates into a measurably higher annual energy yield. ### Does the bifacial DAH DHN-72X16/DG(BB) module make sense on a pitched roof with dark roof tiles? Bifacial technology delivers the greatest benefits when the rear side of the panel has access to reflected irradiance — on a light-colored substrate, a white flat roof, gravel, or grass, the additional energy gain can reach 15–25%. On dark roof tiles, the bifacial effect will be minimal, approximately 5%. For a typical Polish pitched roof, the primary advantages of this series remain the TOPCon cell technology and the durability of the double-glass construction. ### What are the dimensions and weight of the DHN-72X16/DG(BB) panels, and is installation more demanding than with standard modules? The module measures 2,279 × 1,134 × 30 mm and weighs approximately 31.2 kg. These are typical dimensions for 72-cell panels rated above 575 Wp. Due to the weight, installation requires two technicians. The module is compatible with standard mounting systems; however, prior to purchase it is advisable to verify that the roof or ground-mount structure is rated for this type of module. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/en-dhn-72x16-dg-bb-575-590w-b4e310ba5307.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-bb-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.
