Solid all-round for its segment
The DAH DHN-72X16/DG series redefines performance standards through the use of patented Full-Screen technology, which eliminates the problem of dust and water accumulation on the frame edges. The lack of a traditional step between the frame and glass means that deposits are naturally washed away by rain, significantly increasing energy yields compared to classic designs. The use of advanced N-Type TOPCon cells guarantees excellent operating parameters even in low sunlight and low power degradation over a long period of operation. Thanks to the bifacial module design, these panels effectively utilize light reflected from the ground, making them an ideal choice for large-scale ground farms and large commercial installations. The robust double-glass construction provides exceptional resistance to extreme weather conditions and mechanical loads, minimizing the risk of micro-cracks. By choosing the DHN-72X16/DG series, investors gain a solution that combines maximum self-cleaning with innovative cell architecture, directly translating into a faster return on investment and energy production stability for decades. This equipment is dedicated to professionals looking for uncompromising efficiency and reliability in challenging environmental conditions.
Ranking
Signals from the data
Utility-scale and commercial.
N-type TOPCon cells exhibit degradation of ≤1% in Year 1 and ≤0.4%/year in Years 2–30, guaranteeing 87.4% of rated power after 30 years. By comparison, legacy P-type PERC modules typically show 2–3% first-year degradation and 0.45–0.55%/year thereafter, resulting in up to 5–8 percentage points lower energy yield over a 30-year project lifetime.
The patented Full-Screen construction eliminates the step between the frame and the glass, allowing rainwater to naturally flush soiling from the module edges. According to manufacturer data, this reduces soiling-related losses by 6–15% of annual energy yield compared to a conventional aluminum-framed module, a particularly significant advantage at low-rainfall or high-dust-exposure sites.
A bifaciality factor of 85% enables a potential rear-side power gain of 5–25%, depending on ground albedo. This is notably higher than the 70–75% typical of standard bifacial modules, and at ground-mounted installations with high-albedo surfaces (gravel, white membrane, snow) it directly translates into higher annual energy yields.
The Pmax temperature coefficient of -0.29%/°C outperforms the -0.34 to -0.38%/°C typical of PERC modules. At a cell temperature of 65°C (a sunny summer day), the DHN-72X16/DG loses approximately 13.1% of its rated power, whereas a PERC module loses 15.3–17.1% — a real-world gain of 2–4% under high operating temperatures.
DAH Solar has maintained bankable manufacturer status on the BNEF Tier 1 list continuously through Q1, Q3, and Q4 2025. Bankability confirmation is a prerequisite for utility-scale PV projects financed by banks and financial institutions (EPC, project finance), making this series eligible for standard financing agreements without additional manufacturer-risk mitigation provisions.
The product warranty period is 15 years, whereas a direct competitor — the JA Solar Deep Blue 4.0 Pro (comparable wattage, N-type TOPCon) — offers a 25-year product warranty with the same 30-year linear power guarantee. In projects involving bank financing or PPAs with tenors of 20+ years, this gap may be perceived as an additional risk and could require corresponding contractual risk mitigation.
The dual-glass (glass-glass) construction raises the module weight to 31.2 kg, approximately 10–12% heavier than a comparable glass-backsheet format (~28 kg). For rooftop installations on structures with limited load-bearing capacity, or for manual handling at height, this may increase labor costs and necessitate a structural assessment of the mounting system.
- Efficiency of 22.4% matches the TOPCon 550-600W median
- Power density of 224.5 W/m² matches the TOPCon 550-600W median
- 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
