Solid all-round for its segment
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.

Signals from the data
Residential, commercial, utility-scale and shaded-installations.
The Pmax temperature coefficient is -0.29%/°C, a clear improvement over standard PERC cells (-0.35 to -0.40%/°C). 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.
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 Peer comparables — Talesun TM7G72M and Horay Solar HS 182-144 TC-D — do not publish an equally long warranty period, making the DAH DHN-72X16/DG(BB) particularly attractive for projects requiring long-term bankability.
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.
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.
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.
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.
- 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
