None of the directly comparable competitors — Exiom, Premier Energies, or Goldi Solar — hold Tier 1 status according to BNEF. - **N-type TOPCon Cell Technology** - N-type TOPCon cells exhibit a lower light-induced degradation (LID) rate and superior performance at elevated temperatures compared to P-type PERC modules. This translates into higher annual energy yield, particularly in climates with wide temperature swings. - **Efficiency Competitive Within the Segment** - The peak module efficiency of 21.67% (560 Wp variant) is on par with direct competitors: the Exiom EX540-560M and Goldi Solar GS10-B144-GF both reach 21.7%, while Premier Energies matches at 21.67%. DAH Solar keeps pace with the leaders in the 545–560 Wp segment. - **IEC 61215 / IEC 61730 / CE Certifications** - The series carries the full set of certifications required for European markets — IEC 61215, IEC 61730, and CE — along with ISO 9001:2015 quality management compliance, simplifying the process of securing project financing and installation insurance. ## Cons - **Series Discontinued (2021)** - The DHM-T72X10/FS series, introduced in 2021, has been officially discontinued. This results in limited availability of replacement modules in the event of a failure, potential difficulties expanding an installation with identical panels, and no further updates to warranty documentation or technical datasheets from the manufacturer. - **Mixed Cell Technology Within the Series** - The DHM-T72X10/FS series encompasses both P-type PERC and N-type TOPCon variants under the same product line. The differing degradation rates and temperature coefficients between variants complicate offer comparisons and make accurate yield modeling more challenging when selecting a specific variant. - **12-Year Product Warranty** - The workmanship warranty stands at 12 years — in line with the industry standard, but below what some premium manufacturers offer (e.g., LONGi and Jinko, which provide 15-year warranties on newer series). For commercial installations with a 20+ year horizon, this represents a tangible risk of out-of-pocket module replacement costs. ## About this series The DAH DHM-T72X10/FS series is designed for real-world rooftop and farm conditions - where stable output, easier cleaning, and high resistance to environmental factors are essential. A key feature is the **full-screen** design, which minimizes dust and dirt accumulation on the module's front, helping to maintain performance without frequent cleaning. The series is also available as **bifacial**, allowing the panel to utilize reflected light from the ground - a practical advantage on bright rooftops, ground-mounted structures, or carports. The use of **N-type (TOPCon) monocrystalline** cells results in better performance at higher temperatures and slower degradation over time compared to many standard P-type modules. Furthermore, the glass and coating solutions provide **high light transmission and reduced reflection**, improving productivity in less ideal sunlight conditions. This is the choice for investors who want to combine durability, aesthetics, and predictable performance. ## Notable figures - At 21.5% efficiency, this panel is on par with typical \*\*PERC 550-600W\*\* modules - At 214.8 W/m² power density, roof space requirements are typical for \*\*PERC 550-600W\*\* panels - Temperature coefficient of -0.35%/°C matches the \*\*PERC 550-600W\*\* median - At 29.0 kg, this panel is 1.8 kg lighter than \*\*PERC 550-600W\*\* median (30.8 kg) - easier handling during installation - #8152 for efficiency, #10419 for temperature performance out of 14005 panels ## Questions ### What warranty is provided for the DAH Solar DHM-T72X10/FS panels? The DHM-T72X10/FS series comes with a 12-year product warranty covering materials and workmanship, along with a 25-year linear power output warranty. In the first year, the manufacturer guarantees at least 98% of nominal power, with output not falling below 87.55% after 25 years. These are strong warranty terms, fully comparable with the leading N-type module manufacturers on the market. ### What is TOPCon technology and why was it used in the DHM-T72X10/FS series? TOPCon (Tunnel Oxide Passivated Contact) is an N-type monocrystalline cell technology in which a thin tunnel oxide layer suppresses carrier recombination at the rear contact. In practice, this translates to higher module efficiency (approximately 21.7% for the 560 W variant), better performance at elevated temperatures (temperature coefficient of -0.37%/°C), and slower long-term degradation compared to mainstream P-type PERC cells. ### What advantage does the Full Screen design offer in the DAH Solar DHM-T72X10/FS panels? The Full Screen design features a front glass that covers the entire module surface without visible gaps or wide frame borders. This delivers two practical benefits: the panel has a more aesthetically refined appearance on the roof, and it is less prone to dust and dirt accumulation along the edges. The result is easier maintenance and reduced power losses without the need for frequent cleaning. ### Is the DAH Solar DHM-T72X10/FS (560 W) panel suitable for a pitched roof on a single-family home? Yes, although the physical dimensions should be carefully considered: the module measures 2279 x 1134 x 32 mm and weighs approximately 29 kg. Prior to installation, the load-bearing capacity of the roof structure must be verified, and the available roof area should be assessed to confirm that the required number of modules can be accommodated. The 560 W power rating allows a high-performance system to be built with fewer panels, which is a distinct advantage on roofs with limited surface area. ### Is the DAH Solar DHM-T72X10/FS series still available for purchase? The DHM-T72X10/FS series has been discontinued by DAH Solar and is no longer in active production. Individual units may occasionally be available from distributor stock, but for any new installation or system expansion we recommend checking the manufacturer's current product lineup or contacting a distributor to identify a newer, readily available model with comparable specifications. ### How does the degradation of the DAH Solar DHM-T72X10/FS compare to P-type panels? Thanks to N-type TOPCon cells, the DHM-T72X10/FS series exhibits lower annual degradation than typical P-type PERC modules. The linear power warranty guarantees 93.05% of rated output after 10 years and 87.55% after 25 years of operation. P-type modules commonly warrant approximately 80–84% output over the same period, meaning the difference results in measurably higher energy yield throughout the full operational lifetime of the system. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/EN-DHM-T72X10-FS-545-560W-c741a4aa4d2c.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +3.5 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, +3.3 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +3.2 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, +3.1 pp, +5 yr warranty | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, lighter, +2.9 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | Cooler, lighter, +2.9 pp | | [DAH Solar DHM-72X10-540W](https://comparepv.com/panel/dah-dhm-72x10-540w) | 540 W | -15 W, -0.6 pp | | [DAH Solar DHM-T72X10/FS-545W](https://comparepv.com/panel/dah-dhm-t72x10-fs-545w) | 545 W | -10 W, -0.4 pp | | [DAH Solar DHM-T72X10/FS-550W](https://comparepv.com/panel/dah-dhm-t72x10-fs-550w) | 550 W | Very close match | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +95 W, cooler, +3.7 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +90 W, cooler, +3.5 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +85 W, cooler, +3.3 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +80 W, cooler, +3.1 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +75 W, cooler, +2.9 pp | --- Source: https://comparepv.com/panel/dah-dhm-t72x10-fs-555w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
