The result of 161.17 kWh/kW vs. 144.54 kWh/kW confirms a real-world advantage of the frameless front design under soiling conditions. - **Exceptional Snow Load Rating: 5,400 Pa** - A snow load rating of 5,400 Pa places the series in the upper tier of the mechanical class for 60-cell PERC modules, well above the market standard of 2,400–4,000 Pa. This directly translates to reliable performance in climates with wet, heavy snow without the need for additional reinforcing substructures. - **IP68 Protection and 25-Year Linear Power Warranty** - An IP68 ingress protection rating (full submersion sealing) exceeds the IP65 requirement typical for rooftop installations, reducing the risk of moisture-induced degradation in the junction box. The 25-year linear power warranty is the Tier-1 industry standard; DAH Solar has maintained its BNEF Tier 1 listing continuously from at least Q1 2025 through Q4 2025. - **Global FS Patent Coverage Across 18 Jurisdictions** - The frameless-front technology is protected by patents in 18 jurisdictions, underscoring the originality of the solution and differentiating the series from all-black modules that rely solely on black laminate. The rain self-cleaning effect eliminates the primary cause of yield degradation in low-tilt installations. - **10-Busbar, 120-Cell Half-Cut Layout** - The 10-busbar (10BB) design combined with half-cut cells reduces operating current by approximately 50%, lowering resistive I²R losses and improving tolerance to partial shading — particularly relevant for rooftop installations with chimneys or dormers. ## Cons - **Series Discontinued (2022)** - The DHT-M60X10/FS is designated as discontinued. This means replacement modules will be unavailable in the event of physical damage after several years of operation, complicating system expansion with identical modules and potentially requiring a costly full-string replacement. - **Significant Efficiency Gap vs. TOPCon Peers** - The series peaks at 21.3% efficiency, while comparably rated modules such as the Risen RSM96-11-440-460BNDG and SunKean SKT440~460M12-96D4 achieve 23.0–23.02% — an advantage of approximately 1.7 percentage points (roughly 8% in relative terms). The gap stems from the use of legacy PERC cell technology rather than TOPCon, resulting in measurably lower yield per m² at equivalent module area. - **No Bifacial Capability** - The series is monofacial (is\_bifacial: false), precluding any additional energy yield from ground-reflected albedo. On installations over bright surfaces (gravel, snow, white membrane), modern bifacial modules can generate 5–15% more energy annually with no additional roof area required. ## About this series The **DAH Solar DHT-M60X10/FS Full Screen** series is distinguished by its patented global technology for a frameless front, which eliminates one of the biggest problems with solar panel installations - the accumulation of water and dust at the bottom edge of the panel. This allows rainwater to naturally clean the module surface, which, according to TUV Nord field tests, resulted in a **6-15% increase in energy yield** compared to standard modules. The heart of the panel is **half-cut PERC monocrystalline solar cells** arranged in a 120-cell configuration with 10 collective busbars, which reduces resistive losses and improves performance in partially shaded conditions. The design features exceptionally high mechanical strength - it can withstand snow loads of up to 5400 Pa, making it ideal for the Polish climate. An **IP68 degree of protection** guarantees complete sealing even in harsh weather conditions. The panel is available in a black frame version, making it ideal for **rooftop installations on residential and commercial buildings**, where aesthetics play a significant role. This is a solution for investors seeking higher annual yields without compromising on durability. ## Notable figures - Efficiency of 20.4% is 1.6pp below the \*\*TOPCon 400-450W\*\* median (22.0%) - 203.9 W/m² power density is 16.3 W/m² below \*\*TOPCon 400-450W\*\* median (220.2 W/m²) - requires larger installation area - At -0.35%/°C, loses 0.06pp more power per degree than \*\*TOPCon 400-450W\*\* median (-0.29%/°C) - Weight of 23.5 kg is 1.5 kg above \*\*TOPCon 400-450W\*\* median (22.0 kg) - verify structural support - #11683 for efficiency, #10419 for temperature performance out of 14005 panels ## Questions ### Is the DAH Solar DHT-M60X10/FS series still available for purchase? The DHT-M60X10/FS Full Screen series has been discontinued and is no longer offered as new stock by authorized distributors. Isolated units may still appear on the secondary market or in end-of-line inventory. If you are planning a new installation, it is worth asking your dealer about a current replacement from DAH Solar's lineup with comparable specifications and the same Full Screen technology. ### What is the Full Screen technology used in DAH Solar DHT-M60X10/FS panels, and why does it increase energy yield? Full Screen technology eliminates the bottom aluminum frame rail of the module, preventing water and dust from accumulating along the lower glass edge. Rainwater drains freely across the entire panel surface, keeping the module cleaner for longer periods. In field tests certified by TÜV Nord, this effect translated into an increase in annual energy yield of 6 to 15 percent compared with conventional modules fitted with a standard frame. ### What warranty is provided for the DAH Solar DHT-M60X10/FS panels? The manufacturer offered a 12-year product warranty covering material and workmanship defects, along with a 25-year linear power output warranty. This means the module is warranted to maintain its output power in accordance with the degradation curve specified in the datasheet for the full 25-year period. It is advisable to retain your purchase documentation, as warranty claims are handled through an authorized distributor or directly through DAH Solar. ### Can the DAH Solar DHT-M60X10/FS panel withstand Polish winters and heavy snow loads? Yes, the module is designed for demanding climatic conditions. It is rated for a snow load of up to 5,400 Pa, which corresponds to an exceptionally deep snowpack and comfortably exceeds the requirements of Polish construction standards for the vast majority of locations. The IP68 protection rating ensures full ingress protection of the junction box even during prolonged water immersion. ### What is the maximum power output of the DAH Solar DHT-M60X10/FS panel, and what factors affect it? The module's peak power output is 460 Wp under Standard Test Conditions (STC: 1,000 W/m², 25 °C). Under real rooftop conditions, actual output depends on cell temperature, angle of incidence, and soiling level. The monocrystalline PERC cells arranged in a half-cut configuration with 10 busbars reduce resistive losses and improve module performance under partial shading conditions caused, for example, by chimneys or antennas. ### Does the black frame on the DAH Solar DHT-M60X10/FS panels offer any advantage beyond aesthetics? The black anodized frame is primarily an aesthetic feature valued in residential rooftop and commercial installations where the appearance of the building facade matters. From a technical standpoint, the darker frame absorbs marginally more heat, which has a negligible impact on performance in a temperate climate. For investors who prioritize a uniform, modern roofline appearance, it does represent a clear visual advantage over standard silver-framed modules. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Datasheet-DAH-460W-87f3c6f8e0a4.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +50 W, cooler, +4.1 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +50 W, cooler, +4.1 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | Cooler, +3.9 pp, +5 yr warranty | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | Cooler, +3.9 pp, +5 yr warranty | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | Cooler, +3.9 pp, +5 yr warranty | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | Cooler, +3.9 pp, +5 yr warranty | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | Cooler, +3.9 pp, +5 yr warranty | | [DAH Solar DHT-M60X10-430W](https://comparepv.com/panel/dah-solar-dht-m60x10-430w) | 430 W | -10 W, -0.5 pp | | [DAH Solar DHT-M60X10-435W](https://comparepv.com/panel/dah-solar-dht-m60x10-435w) | 435 W | -0.2 pp | | [DAH Solar DHM-60X10/FS(BW)-445W](https://comparepv.com/panel/dah-dhm-60x10-fs-bw-445w) | 445 W | +0.2 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +120 W, cooler, +4.4 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +115 W, cooler, +4.2 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +110 W, cooler, +4.0 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +100 W, cooler, +4.0 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +100 W, cooler, +4.0 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | +105 W, cooler, +3.9 pp | --- Source: https://comparepv.com/panel/dah-solar-dht-m60x10-440w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
