Solid all-round for its segment
The DAH DHN-72X16/DG 575-590W series is designed for maximum energy yield from a limited surface area - without compromising durability. These are bifacial modules that can also generate power from reflected light from the ground, thereby increasing energy production on flat roofs, carports, and ground-mounted farms. The use of N-type cells supports stable operation and slower degradation, which is important for investments planned for decades. The double-glass construction improves resistance to moisture, saline fog, and mechanical loads - good news for installations exposed to snow, wind, and harsh environmental conditions. In addition, the modules have enhanced PID resistance, which reduces the risk of power drops in demanding installations. This series is ideal for installers and investors who want to maximize kWh per square meter and ensure long-term, reliable operation.
Ranking
Signals from the data
Commercial, utility-scale, shaded-installations and hot-climate.
The efficiency range of 22.26–22.84% places this series on par with its closest competitors: Talesun TM7G72M and Horay Solar HS 182-144 TC-D (both at 22.8%) and AE Solar HORIZON CMD-144BDS (22.86%). The gap to the segment leader is a mere 0.02 percentage points — statistically negligible in real-world deployment.
The Pmax temperature coefficient of -0.29%/°C is a clear improvement over typical PERC modules (-0.35%/°C). In the Polish climate, where cell temperatures commonly reach 60–70°C during summer, this difference translates to approximately 2–3% higher energy yield in the warmest months. Annual degradation is ≤0.4%/year (years 2–30), compared to ≤0.55%/year for older technologies.
A bifaciality factor of up to 85% enables an additional 5–25% energy gain from ground-reflected irradiance, particularly on flat rooftops, carports, and agrivoltaic installations. The rear glass replaces the conventional backsheet, improving resistance to moisture and salt mist while increasing mechanical strength: certified snow load of 5,400 Pa and wind load of 2,400 Pa (wind class 13).
The manufacturer guarantees ≥89.4% of rated power after 25 years and ≥87.4% after 30 years, with first-year degradation ≤1%. The product warranty covers 15 years. Comparable series from Talesun and Horay Solar offer equivalent terms, making these warranty conditions a segment standard rather than a premium differentiator.
DAH Solar maintains continuous BNEF Tier 1 status, confirmed in both Q1 2025 and Q4 2025, meeting BloombergNEF's tightened post-2025 requirements (minimum 10 MW project threshold). Tier 1 bankability is a key prerequisite for project finance and insurance on commercial installations above 50 kWp.
Modules in this series weigh 31.2–32.0 kg, approximately 5–6 kg more than comparable 575–590 W single-glass modules (typically 25–27 kg). For larger rooftop installations, this may require a structural load assessment and increases installation labor, resulting in higher Balance of System (BoS) costs.
- Efficiency of 22.4% matches the TOPCon 550-600W median
- At 224.5 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
- #4620 for efficiency, #2165 for temperature performance out of 14005 panels
