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. - **Full-Screen Design – Self-Cleaning Performance** - 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. - **High Bifaciality Factor of 85%** - 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. - **Favorable Temperature Coefficient of Power** - 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. - **BNEF Tier 1 Status – Bankability** - 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. ## Cons - **15-Year Product Warranty** - 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. - **Weight of 31.2 kg – Glass-Glass Construction** - 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. ## About this series 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. ## Notable figures - Efficiency of 22.8% matches the \*\*TOPCon 550-600W\*\* median - At 228.4 W/m² power density, this panel generates 4.0 W/m² more per unit area than \*\*TOPCon 550-600W\*\* median (224.4 W/m²) - 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 - In the top 19% for efficiency among all TOPCon panels ## Questions ### What is the Full-Screen technology in DAH Solar DHN-72X16/DG panels and does it actually increase energy yield? Full-Screen technology eliminates the traditional step between the frame and the glass, preventing dust and water from accumulating along the module edges. Rainfall naturally rinses deposits off the entire surface, which according to DAH Solar translates into a 6–15% increase in energy production compared to conventional module designs. This solution is protected by a global patent and performs particularly well in locations with high dust levels or infrequent rainfall. ### What warranties apply to the DAH Solar DHN-72X16/DG series — product warranty and power output warranty? The DHN-72X16/DG series comes with a 15-year product warranty covering manufacturing defects and material failures, and a 30-year linear power output warranty. After 30 years of operation, the panel is guaranteed to retain at least 87.4% of its nominal power. DAH Solar is a Tier 1 manufacturer, which implies bankable creditworthiness and long-term warranty stability over the full 30-year horizon. ### What is the maximum power output and module efficiency of the DAH DHN-72X16/DG panel? The highest-power variant in the series reaches 590 Wp with a module efficiency of up to 22.84%. These figures are achieved through 144 half-cut N-Type TOPCon cells, which deliver higher efficiency and lower degradation than standard P-Type cells. For installations with limited roof or ground area, this means more kilowatt-hours generated per square meter. ### Do DAH DHN-72X16/DG panels perform well under overcast conditions and at low temperatures? Yes. N-Type TOPCon cells exhibit superior low-light performance compared to P-Type cells, resulting in higher energy yields on cloudy days typical of Central European climates. The low temperature coefficient of power at -0.29%/°C means the panels lose less output during heat waves, while also performing efficiently under bright, cold winter sunlight. ### Is the DHN-72X16/DG series suitable for ground-mounted utility-scale installations, and how does its bifacial design work? The DHN-72X16/DG series is designed primarily for large ground-mounted and commercial installations. Its bifacial, glass-glass construction allows the module to absorb light reflected from the ground surface — light-colored gravel ballast or grass on a sunny day can boost rear-side yield by 5–25%. The glass-glass design also provides greater resistance to mechanical loads and moisture ingress compared to standard modules with a polymer backsheet. ### Is DAH Solar a reliable manufacturer and will DHN-72X16/DG panels be supported and serviced 20 years from now? DAH Solar appears on the Bloomberg NEF Tier 1 list, indicating that the company meets rigorous financial and manufacturing criteria. The company operates its own cell and module production lines, exports to European markets, and is publicly listed. Tier 1 status is a key factor when assessing warranty risk in the context of the 30-year power output warranty offered for the DHN-72X16/DG series. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/en-dhn-72x16-dg-575-590w-2c24cf2f432f.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -30 W, lighter, +2.0 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +50 W, lighter, +2.0 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -35 W, lighter, +1.8 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +45 W, lighter, +1.8 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +40 W, cooler, +1.6 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | -40 W, lighter, +1.6 pp | | [DAH Solar DHM-72X10-540W](https://comparepv.com/panel/dah-dhm-72x10-540w) | 540 W | -50 W, hotter, -1.9 pp | | [DAH Solar DHM-T72X10/FS-545W](https://comparepv.com/panel/dah-dhm-t72x10-fs-545w) | 545 W | Hotter, -1.8 pp, -5 yr warranty | | [DAH Solar DHM-T72X10/FS-550W](https://comparepv.com/panel/dah-dhm-t72x10-fs-550w) | 550 W | Hotter, -1.6 pp, -5 yr warranty | | [DAH Solar DHM-72X10-555W](https://comparepv.com/panel/dah-dhm-72x10-555w) | 555 W | Hotter, -1.4 pp, -5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +60 W, lighter, +2.4 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +55 W, lighter, +2.2 pp | --- Source: https://comparepv.com/panel/dah-dhn-72x16-dg-590 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.
