None of the peer comparables (Talesun, Horay Solar, AE Solar) appear on this list, making DAH a clearly superior choice for projects requiring external financing. - **Low Temperature Coefficient — N-type TOPCon (-0.29%/°C)** - The measured temperature coefficient is -0.29%/°C, compared to the typical -0.35 to -0.40%/°C for PERC modules. At a cell temperature of 65°C (a summer day in Poland), this advantage over PERC translates to approximately 2.5–3% higher instantaneous yield — equivalent to a real gain of 2–3 MWh of additional annual energy generation for a 100 kWp system. - **30-Year Power Warranty: Minimum 87.4% After 30 Years** - The manufacturer's guaranteed linear degradation schedule ensures at least 87.4% of nominal power output after 30 years. Few manufacturers in this segment offer a comparable warranty level, and with a glass-glass construction and N-type technology (minimal LID degradation), real-world yield over the full service life is statistically expected to exceed the guaranteed minimum. - **Mechanical Strength: 5,400 Pa Snow Load / 2,400 Pa Wind Load** - The glass-glass construction (2 mm + 2 mm) has been tested to snow loads of 5,400 Pa and wind loads of 2,400 Pa, meeting IEC requirements for alpine zones and high-wind environments. By comparison, standard backsheet modules are typically certified to 2,400 Pa snow load and 1,600–2,400 Pa wind load. - **KIWA PV Evolution Labs Top Performer 2025** - The series has been ranked as a Top Performer in the independent PV Module Reliability Scorecard 2025 by KIWA PV Evolution Labs — third-party reliability validation that goes beyond standard TÜV/IEC certifications and carries significant weight during due diligence assessments for utility-scale projects. ## Cons - **Smaller Service Network vs. the Big 4** - Despite its BNEF Tier 1 status, DAH Solar holds a notably smaller share of the European market than Jinko Solar, JA Solar, LONGi, or Trina Solar (all founded between 2006 and 2007). In practice, this may result in longer warranty claim response times in Poland and potentially higher bank financing spreads for PV farm projects above 1 MWp, where lenders tend to prefer Big 4 modules backed by a documented local service presence. ## About this series The DAH Bifacial Double Glass Module series redefines performance standards by maximizing the use of reflected and scattered light. Thanks to the use of **bifacial energy generation**, these modules allow for a significantly higher power yield from the back side of the cells, which drastically shortens the return on investment time, especially on high-albedo surfaces such as light gravel or bright roof membranes. The construction based on a **glass-glass structure** provides unparalleled resistance to PID degradation and corrosive factors such as ammonia or salt mist, making them an ideal choice for the agro sector and coastal areas. The use of modern **N-type TOPCon cells** guarantees not only record efficiency but also minimal power degradation over time and excellent performance in low-light conditions. What sets this series apart from the competition is a set of innovative solutions that prevent dust and sediment buildup on the edges, which, combined with extreme mechanical strength, minimizes maintenance costs. These panels are dedicated to demanding photovoltaic farms, industrial installations, and modern carports, where the priority is **maximum system longevity** exceeding three decades. By choosing these modules, the investor opts for uncompromising technology that effectively handles the toughest environmental challenges. ## Notable figures - Efficiency of 22.5% matches the \*\*TOPCon 550-600W\*\* median - At 224.5 W/m² power density, roof space requirements are typical for \*\*TOPCon 550-600W\*\* panels - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 550-600W\*\* median - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof - #4222 for efficiency, #6093 for temperature performance out of 14005 panels ## Questions ### What warranty does the DAH Solar Bifacial Double Glass Module series carry? DAH Solar provides a 15-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty for the Bifacial Double Glass Module series. This means the manufacturer guarantees a defined minimum power yield over three decades — one of the strongest warranty standards in the utility and commercial module segment and a solid foundation for return-on-investment calculations. ### What is N-type TOPCon technology and why does it matter in the DAH Solar Bifacial Double Glass series? N-type TOPCon is a photovoltaic cell architecture that uses a higher-purity silicon substrate, virtually eliminating the LID (Light-Induced Degradation) effect. Compared to conventional PERC cells, N-type TOPCon cells offer a lower temperature coefficient of power (approximately -0.29%/°C), superior performance under overcast skies and low-irradiance conditions, and slower long-term degradation throughout the full 30-year operational lifetime. ### How much additional energy can the DAH Solar Bifacial Double Glass Module generate thanks to its bifacial design? With a bifacial factor of approximately 80–85%, modules in the Bifacial Double Glass series can generate 5 to 25% more energy than a conventional monofacial panel of the same nominal power rating of 590 Wp. The actual gain depends on ground albedo: light-gray gravel, white roofing membranes, and snow all significantly increase reflected irradiance and boost rear-side yield. ### Are DAH Solar Bifacial Double Glass Modules suitable for agrivoltaic installations and coastal environments? Yes, this is one of the series' key advantages. The glass-glass construction provides resistance to ammonia corrosion (agricultural environments) and salt mist (coastal zones). Ammonia and salt spray resistance certifications ensure the modules meet stringent requirements for agrivoltaic farms and industrial installations in harsh environmental conditions, where standard aluminum-framed panels degrade more rapidly. ### Is the DAH Solar Bifacial Double Glass Module a good fit for carport structures or utility-scale industrial installations? Yes, the series is specifically designed for such applications. The glass-glass structure provides the transparency and aesthetics required in carports and pergolas, while the high mechanical strength allows the modules to meet snow load and wind load standards in large-scale installations. A power output of up to 590 Wp combined with the 30-year linear power warranty makes this series economically attractive for commercial investors and utility-scale PV project developers. ### Is DAH Solar a reputable manufacturer, and how is the quality of the Bifacial Double Glass series assessed? DAH Solar is listed as a Tier 1 manufacturer by BloombergNEF, meaning its projects qualify for bankable financing without additional quality assurances. The company is a long-established market participant with its own manufacturing facilities in China and holds IEC, MCS, and various regional certifications. The Bifacial Double Glass series was featured at trade shows in 2024 as part of the company's frameless N-type TOPCon module portfolio. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Datasheet-DAS-DH144NA-xxx_575-590-2bf2a2e1eed5.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.3 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +2.1 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +50 W, cooler, +1.9 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, 15 kg lighter, +1.9 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | -40 W, lighter, +1.9 pp | | [DAH Solar DHM-72X10-540W](https://comparepv.com/panel/dah-dhm-72x10-540w) | 540 W | Hotter, -1.6 pp, -5 yr warranty | | [DAH Solar DHM-T72X10/FS-545W](https://comparepv.com/panel/dah-dhm-t72x10-fs-545w) | 545 W | Hotter, -1.4 pp, -5 yr warranty | | [DAH Solar DHM-T72X10/FS-550W](https://comparepv.com/panel/dah-dhm-t72x10-fs-550w) | 550 W | Hotter, -1.2 pp, -5 yr warranty | | [DAH Solar DHM-72X10-555W](https://comparepv.com/panel/dah-dhm-72x10-555w) | 555 W | Hotter, -1.0 pp, -5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +70 W, lighter, +2.7 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +65 W, lighter, +2.5 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +60 W, lighter, +2.3 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +55 W, lighter, +2.1 pp | --- Source: https://comparepv.com/panel/dah-solar-das-dh144na-580w 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.
