Middle of its segment, weak in heat
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.

An independent field test conducted by TüV Nord demonstrated an 11.5% increase in energy yield compared to standard framed modules. The frameless front surface enables self-cleaning through rainfall, meaningfully reducing soiling losses without the need for frequent maintenance.
DAH Solar has appeared on the BloombergNEF Tier 1 list at least since Q1 2025, confirming the manufacturer's bankability and financial credibility. None of the directly comparable competitors — Exiom, Premier Energies, or Goldi Solar — hold Tier 1 status according to BNEF.
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.
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.
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.
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.
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.
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.
- Module efficiency of 21.7% is 0.8pp below average for TOPCon 550-600W panels (median: 22.4%)
- 216.7 W/m² power density is 7.7 W/m² below TOPCon 550-600W median (224.4 W/m²) - requires larger installation area
- -0.35%/°C temperature coefficient - 0.06pp worse than TOPCon 550-600W median (-0.29%/°C), expect higher hot weather losses
- Weight of 29.0 kg (2.2 kg below TOPCon 550-600W median of 31.2 kg) allows easier transport and roof mounting
- Ranked #7588 out of 14005 panels for efficiency in the database
