Under summer operating conditions with modules heated to ~70°C, this translates to approximately 3% higher energy yield compared to previous-generation technology. - **30-Year Power Warranty (≥87.4%)** - The manufacturer guarantees ≥89.4% of nominal power output after 25 years and ≥87.4% after 30 years, with degradation ≤0.4%/year following the first year. Peer comparables in the segment (KDM, Lina Energy) typically offer a standard 25-year warranty, making this series more financially attractive over a long-term investment horizon. - **Full-Screen: Confirmed +11.5% Energy Yield Gain** - Full-Screen technology eliminates the front frame, enabling self-cleaning of dust through rainfall. An independent field test by TÜV Nord confirmed an 11.5% increase in energy production compared to standard framed modules, with a direct impact on annual energy yield in low-tilt installations. - **N-type TOPCon Cells – Minimal LID Degradation** - N-type TOPCon technology virtually eliminates Light Induced Degradation (LID) characteristic of P-type PERC cells. Declared degradation is ≤1% in the first year and ≤0.4%/year over the subsequent 29 years, resulting in higher cumulative energy yield across the full system lifetime. - **BNEF Tier 1 – Bankability Confirmed Q4 2025** - DAH Solar has maintained Tier 1 status per BloombergNEF continuously throughout 2025 (confirmed Q1–Q4 2025), which is a key bankability criterion for PV project financing and insurer requirements. The manufacturer has been operating since 2009, ensuring long-term service and warranty continuity. ## Cons - **Efficiency Below Peer Comparable Leader** - The maximum module efficiency of this series is 22.53%, while the Luxor Solar ECO LINE N-TYPE TOPCON NON-REFLECT in the same power class (440 Wp) achieves 22.86% — a gap of 0.33 percentage points. On roof space-constrained installations, this translates to approximately 1.5% fewer modules for the same peak power output, or slightly lower peak power with an identical module count. ## About this series The DAH DHN-54X16/DG series was designed to maximize energy yields in real-world operating conditions - not just in the lab. These are **double-glass** modules with **N-type TOPCon cells**, which provide high parameter stability and excellent resistance to degradation and PID effects. This translates to more predictable energy production over the long term, especially in installations designed for predictable performance and low risk of yield losses. Another key feature of the series is the **bifacial design** - the module can utilize reflected light from the ground, which can significantly increase energy yield in locations where every kilowatt-hour counts, such as on flat roofs, carports, or surfaces with light-colored surfaces. An additional advantage is the **Full-Screen technology**, which helps to prevent water and dust accumulation on the edges, reducing power losses and the need for frequent cleaning. This series is ideal for investors and installers who want to combine aesthetics, durability, and real production growth in demanding locations. ## Notable figures - Efficiency of 22.3% matches the \*\*TOPCon 400-450W\*\* median - At 222.8 W/m² power density, roof space requirements are typical for \*\*TOPCon 400-450W\*\* panels - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 400-450W\*\* median - At 23.5 kg, this panel is 1.5 kg heavier than the \*\*TOPCon 400-450W\*\* median (22.0 kg) - more demanding for installation crews - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### What warranty does the DAH Solar DHN-54X16/DG series carry? The DHN-54X16/DG series is backed by a 25-year product warranty covering manufacturing defects and a 30-year linear power output warranty. After 30 years of operation, the module is guaranteed to retain at least 87.4% of its nominal power. Degradation is capped at 1% in the first year and 0.4% per year thereafter. This is one of the most competitive warranty schedules available in the N-type module segment. ### What does bifacial technology offer in the DAH DHN-54X16/DG series, and when does it pay off? Bifacial design means the module generates power from both its front and rear surfaces by capturing light reflected off the ground or surrounding surfaces. In practice, the bifacial gain is most noticeable on flat roofs with light-colored membranes, carports, and ground-mounted systems installed over bright or snow-covered ground. Energy yield gains typically range from 5–15% compared to a monofacial module. On a dark-colored pitched roof the difference will be minimal; however, the rear glass still improves the module's long-term mechanical durability. ### Will the DAH Solar DHN-54X16/DG panels perform well in the Polish climate, where overcast conditions are common? Yes. N-type TOPCon cells exhibit superior low-irradiance and diffuse-light performance compared to standard PERC cells — conditions that are the norm in Poland during autumn and winter. An additional advantage is the low power temperature coefficient of -0.29%/°C, which means reduced losses on hot summer days and better output during cooler periods of the year. ### How much does the DHN-54X16/DG module weigh, and can a typical roof structure handle the load? The module weighs approximately 23.5 kg and measures 1722 × 1134 × 30 mm. The dual-glass construction is somewhat heavier than conventional single-glass modules with a backsheet, so it is advisable to verify the roof's load-bearing capacity with an installer or structural engineer before mounting. Most standard steel racking systems on pitched and flat roofs handle this weight without issue, but older buildings should be assessed individually. ### How does the DAH DHN-54X16/DG series differ from the FS models from the same manufacturer? The DG designation (double glass) indicates a dual-glass construction in which the traditional polymer backsheet is replaced by a rear glass pane. The FS (Full-Screen) series is primarily distinguished by a redesigned frame profile that minimizes dust and water accumulation along the module edges. Both series can incorporate N-type TOPCon cells and bifacial architecture, but the DG line emphasizes mechanical resilience and longevity, making it particularly well-suited for ground-mounted systems and commercial installations. ### Is DAH Solar a reliable manufacturer, and do the DHN-54X16/DG modules hold relevant certifications? DAH Solar is listed as a Tier-1 manufacturer by Bloomberg NEF, confirming its financial stability and consistent production quality. The DHN-54X16/DG modules carry IEC certifications and the CE Declaration of Conformity required for the European market. The company has an established track record of supplying installations across Europe, Australia, and the United States, which translates into accessible warranty service and long-term supply chain reliability. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/en-dhn-54x16-dg-430-440w-dae081b1fd9f.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +50 W, lighter, +2.0 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +50 W, cooler, +2.0 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +50 W, cooler, +2.0 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +50 W, cooler, +2.0 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +50 W, cooler, +2.0 pp | | [DAH Solar DHN-54X16/DG-430W](https://comparepv.com/panel/dah-dhn-54x16-dg-430w) | 430 W | -0.3 pp | | [DAH Solar DHN-54X16/DG-440W](https://comparepv.com/panel/dah-dhn-54x16-dg-440w) | 440 W | +0.2 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +75 W, cooler, +2.7 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +60 W, cooler, +2.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +70 W, cooler, +2.4 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +55 W, cooler, +2.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +65 W, cooler, +2.2 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +65 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/dah-dhn-54x16-dg-435 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.
