The DAH DHM-T60X10/FS series was designed with real-world losses in mind, which are often caused by water, dust, and snow in Polish conditions. A key feature is the Full-Screen (anti-pylon) design with a sealed glass edge - without the traditional "edge" where dirt can accumulate. This makes the module easier to clean during rainfall, and ensures that the installation maintains consistent performance over time, without production fluctuations after cleaning.

In practice, this means lower costs and fewer service downtimes, especially on roofs with a small slope, near roads, fields, or industrial facilities. The series utilizes a modern architecture for silicon solar cells, designed for stable operation even with partial soiling and in varying weather conditions. Another advantage is its robust construction, which better withstands wind and snow loads.

This is a good choice for homes, businesses, and PV farms that want to minimize energy losses and reduce maintenance costs.

What owners get
Full-Screen Design – TÜV Nord-Verified +11.5% Energy Yield

The frameless module front eliminates the dirt-accumulating frame edge. In published TÜV Nord field tests, the FS series generated 11.5% more energy than standard framed modules under soiling conditions. TÜV Nord awarded the series its Outdoor Field Performance Award, providing independent confirmation of the real-world energy yield gain.

21.55% Efficiency – Top Tier among 182 mm PERC Modules

A peak efficiency of 21.55% marginally outperforms comparable series such as the Jinko Solar JS182MHC120 (21.48%) and Vikram Solar SOMERA (20.91%), placing the DHM-T60X10/FS among the leading products in the 182 mm PERC segment.

BNEF Tier-1 Manufacturer (Q1 2025)

DAH Solar maintains BloombergNEF Tier-1 status as confirmed in Q1 2025, establishing the module's bankability. This facilitates project financing through commercial lenders and reduces project risk for institutional investors.

Temperature Coefficient of –0.290%/°C

A Pmax temperature coefficient of –0.290%/°C is favorable for PERC technology and limits power losses at typical summer module operating temperatures of 50–70°C. This translates into meaningfully higher energy yield during peak production hours.

Trade-offs
Series Discontinued

The DHM-T60X10/FS is listed as discontinued (launched 2022). This results in limited module availability for system expansions and replacements, as well as a risk of extended warranty claim lead times. DAH Solar has superseded this series with newer N-type models under the DHN TOPCon line.

PERC Technology Eclipsed by TOPCon

As of 2025, the majority of new Tier-1 installations use N-type TOPCon cells, which deliver lower LID, a degradation rate of approximately 0.40–0.45%/year (vs. 0.55%/year for this series per DAH Solar's warranty datasheet), and residual power output of >87% after 25 years. The guaranteed minimum for the DHM-T60X10/FS is 84.8% after 25 years.

12-Year Product Warranty

Leading Tier-1 manufacturers in their current series — including Jinko Tiger Neo, LONGi Hi-MO X6, and Trina Vertex S+ — offer a standard 15-year product warranty. The 12-year coverage on this series falls below the current market standard, which may be a deciding factor for commercial installations with long financing horizons.

Common questions

6 answered
Is the DAH Solar DHM-T60X10/FS series still available for purchase?
The DHM-T60X10/FS series has been discontinued and is no longer actively offered by DAH Solar. Isolated units may still be found in distributor warehouses; however, availability is extremely limited. If you require similar Full-Screen technology backed by a current manufacturer warranty, it is advisable to ask your dealer about a more recent series within the DAH Solar portfolio.
What warranty coverage applies to the DAH Solar DHM-T60X10/FS panels?
DAH Solar provides a 12-year product warranty covering materials and workmanship, along with a 25-year linear power output warranty. At the 15-year mark, the module is guaranteed to retain at least 90.3% of its nominal rated power, and at the 25-year mark no less than 84.8% of the original output value. The warranty is valid provided the system is installed by a qualified contractor and operated in accordance with the product documentation.
How does the Full-Screen technology in the DHM-T60X10/FS series work, and does it genuinely help with soiling losses?
Full-Screen is a frameless, flush-edge glass construction that eliminates the conventional aluminum frame surrounding the module. That frame channel is where dust, road particulates, and post-rain residue typically accumulate. Without this obstruction, rainwater flows more freely across the entire panel surface, providing effective self-cleaning. DAH Solar states that this design can reduce energy yield losses by 6–15% compared to conventionally framed modules operating under equivalent soiling conditions.
Is the DHM-T60X10/FS panel suitable for low-pitch or flat roofs?
Yes, this is one of the key advantages of the series. Low-tilt roofs (below 15°) are the most susceptible to the accumulation of dust, standing water, and snow, since gravity provides less assistance with self-cleaning. The frameless Full-Screen concept is most effective precisely in this application, eliminating the primary soiling accumulation point and reducing the frequency of manual panel cleaning required.
How much does the DAH Solar DHM-T60X10/FS panel weigh, and will a standard rooftop mounting structure support it?
The module weighs approximately 23.5 kg with overall dimensions of 1903 × 1134 × 32 mm. This is a typical mass for a 465 W module in this class. Standard aluminum racking systems are generally rated for 15–20 kg per module, so it is advisable to verify the load-bearing capacity of the specific roof structure with your installer prior to commissioning. The panel is rated to withstand wind loads of up to 2,400 Pa and snow loads of up to 5,400 Pa, which is consistent with Central European climatic conditions.
How many DAH Solar DHM-T60X10/FS modules do I need for a typical residential system of 6–10 kWp?
At a peak power rating of 465 W per module, a 6 kWp system requires approximately 13 panels, while a 10 kWp system requires approximately 22 panels. The actual count depends on available roof area, orientation, and shading conditions. Each module occupies approximately 2.16 m² of roof surface, meaning a 22-module array requires just under 48 m² of usable roof space.
