The gap to the segment leader is a mere 0.02 percentage points — statistically negligible in real-world deployment. - **Low Temperature Coefficient — TOPCon Advantage** - 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. - **Bifacial Double-Glass Construction** - 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). - **30-Year Linear Power Warranty** - 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. - **BNEF Tier 1 — Confirmed Bankability** - 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. ## Cons - **Higher Weight — Double-Glass Penalty** - 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. ## About this series 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. ## Notable figures - At 22.8% efficiency, this panel is on par with typical \*\*TOPCon 550-600W\*\* modules - 228.4 W/m² power density - 4.0 W/m² more than \*\*TOPCon 550-600W\*\* median (224.4 W/m²), more power per roof area - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 550-600W\*\* panels - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface - #2617 for efficiency, #2165 for temperature performance out of 14005 panels ## Questions ### What is the warranty coverage for DAH Solar DHN-72X16/DG 575–590W panels? The DHN-72X16/DG series comes with a 15-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty. After 30 years, the manufacturer guarantees a minimum of 87.4% of nominal power output. This is one of the longest power warranties currently available on the market, making the series particularly attractive for long-term investments. ### Does the bifacial design of the DHN-72X16/DG panels provide a meaningful energy yield gain, and by how much? Yes, the bifacial design in this series translates into a measurable energy yield gain. The rear side of the module can contribute an additional 5 to 25% of power above the nominal rating, depending on the albedo reflectivity of the underlying surface (light-colored gravel ballast, white roofing membrane, or light-colored ground surface). The bifaciality factor is approximately 80±5%. The greatest benefit is achieved in ground-mounted systems, flat-roof installations, and carport structures, where the rear side of the panel has direct exposure to reflected irradiance. ### Is the DAH Solar DHN-72X16/DG series suitable for flat-roof and ground-mounted installations? Yes, this is one of the primary intended applications for this series. The double-glass (glass-glass) construction provides structural resistance to snow loads up to 5,400 Pa and wind loads up to 2,400 Pa, while the absence of a rear backsheet eliminates the risk of degradation under high-humidity conditions and salt mist exposure. Combined with the bifacial design, the modules deliver particularly high performance on flat roofs and ground-mounted structures, where the rear side benefits from reflected irradiance. ### What is TOPCon N-type cell technology and how does it differ from standard PERC cells? TOPCon (Tunnel Oxide Passivated Contact) is a cell technology based on N-type silicon, offering higher efficiency (up to 22.84% for this series) and a slower degradation rate compared to the more widely used P-type PERC cells. The key practical difference is that N-type modules have a lower temperature coefficient of power (-0.29%/°C), meaning they lose less power output during high-temperature conditions. They are also significantly more resistant to the PID (Potential-Induced Degradation) effect, which can reduce power output in large-scale, high-voltage installations. ### What are the dimensions and weight of the DAH Solar DHN-72X16/DG module — is it difficult to install? Each module in this series measures 2278×1134×30 mm and weighs 30.8 kg. This is a standard form factor for large 72-cell modules designed for commercial and industrial installations. Due to the weight and size, installation requires a minimum of two people or the use of mechanical lifting equipment, particularly on pitched roofs. Logistics are generally more straightforward on ground-mounted systems and flat roofs. ### Is DAH Solar a reliable manufacturer — what is its standing in the market? DAH Solar is a Chinese manufacturer classified as Tier 1 by independent industry agencies, confirming both financial stability and consistent production quality. The company supplies modules to large-scale commercial and utility-scale projects worldwide. Tier 1 classification is particularly significant when securing project financing through banks and leasing companies, as it reduces the counterparty risk associated with long-term manufacturer warranty obligations. ## 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-590w 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.
