DAH Solar holds a patent on this design, confirming its originality. - **1/3-Cut Cells + Multi-Busbar (MBB)** - Splitting each cell into three sections shortens the current path and reduces resistive losses, while the multi-busbar (MBB) design narrows the inter-busbar spacing, improving energy yield under diffuse irradiance (overcast skies, fog). In practice, this results in a higher performance ratio (PR) for systems deployed in temperate climates. - **BNEF Tier-1 Manufacturer** - DAH Solar has maintained continuous Tier-1 status according to BloombergNEF — confirmed on both the Q1 2025 and Q3 2025 lists. This designation is required by most lenders financing commercial PV projects and ensures project bankability and insurability. - **All-Black Aesthetic for the Residential Segment** - The black frame combined with Full Screen technology produces a uniform, dark module surface — a compelling sales argument for rooftop installations visible from the street, a segment in which aesthetics meaningfully influence the purchasing decision. ## Cons - **Series Discontinued (2021)** - The DHM-60X10/FS(BB) series has been officially discontinued. This limits the availability of replacement modules in the event of mechanical damage and creates a risk of manufacturer technical support being withdrawn after 2030, as the product warranty period approaches its end. - **Efficiency Notably Below Segment Benchmark** - The 20.39–21.08% efficiency range is 1.7–2.4 percentage points below two of the three identified peer comparables — Sunlike Solar SKT420~455M10-108D6 and IBC Solar LS-TA2 — both of which achieve 22.8% at the same maximum power of 455 Wp. On a typical 30 m² rooftop, this efficiency gap translates to approximately 200–350 kWh of lost annual generation. - **12-Year Product Warranty — Below Market Standard** - The current market norm among Tier-1 manufacturers in 2024–2025 is a 15–25 year product warranty. The 12-year coverage places this series below that standard, representing an additional risk in long-term project financing arrangements or PPA contracts. - **Monofacial Design — No Bifacial Gain** - The module is monofacial (is\_bifacial: false). Installations over high-albedo surfaces (gravel, white roofing membrane) forgo the additional reflected-light yield gain — typically 5–15% — available from bifacial panels in the same power class. ## About this series The DAH Full Screen DHM-60X10/FS(BB) panel series revolutionizes the market thanks to its patented frameless edge design, which effectively eliminates the problem of dirt accumulation. In traditional modules, the frame protrudes above the glass, creating a ledge where dust, dirt, and water accumulate, which directly leads to efficiency drops and the risk of hot-spot formation. Thanks to the innovative **Full Screen technology**, rainwater flows freely across the entire surface, which provides a self-cleaning effect and allows for higher energy production on an annual scale. The use of advanced **1/3 cut cells** in combination with multi-busbar (MBB) technology minimizes internal resistance and significantly improves the module's performance parameters in low light. The aesthetic **Black Frame** finish makes this series an excellent choice for single-family homeowners who care about a modern roof appearance. This solution is particularly recommended for low-tilt installations where standard panels require frequent maintenance. The unique construction guarantees **high mechanical resistance** and maintenance-free operation, distinguishing these modules from competing products. It is the optimal choice for investors focusing on maximum energy yield and minimizing service costs over the years. ## Notable figures - At 20.9% efficiency, this panel is on par with typical \*\*PERC 450-500W\*\* modules - At 208.5 W/m² power density, roof space requirements are typical for \*\*PERC 450-500W\*\* panels - At -0.35%/°C, hot weather performance is typical for \*\*PERC 450-500W\*\* panels - #10362 for efficiency, #10419 for temperature performance out of 14005 panels ## Questions ### Is the DAH Solar Full Screen DHM-60X10/FS(BB) series still available for purchase? The DHM-60X10/FS(BB) series has been discontinued by DAH Solar and is no longer actively manufactured. Limited stock may still exist with certain distributors; however, full availability and long-term supply should not be expected. If you are looking for modules with comparable specifications and Full Screen technology, it is advisable to consult your dealer about newer DAH Solar series or equivalent Tier 1 manufacturer offerings. ### How does the Full Screen technology in DAH DHM-60X10/FS(BB) panels work, and how does it differ from conventional modules? In standard panels, the aluminum frame protrudes above the glass surface, creating a ledge that traps dust, particulates, and water. Full Screen technology eliminates this issue through a patented frameless edge design: rainwater flows freely across the entire module surface, providing a self-cleaning effect. In practice, this results in higher annual energy yield and a reduced need for manual cleaning — a particularly significant advantage on rooftop installations with low tilt angles. ### What warranty is offered on DAH Solar DHM-60X10/FS(BB) panels? The manufacturer provides a 12-year product warranty covering materials and workmanship, as well as a 25-year linear power output warranty. This means that over a quarter century of operation, the module's power output is guaranteed not to fall below the levels specified in the linear warranty schedule. DAH Solar holds Tier 1 manufacturer status, which substantiates the credibility of its warranty commitments and reflects the company's financial stability. ### Do DAH DHM-60X10/FS(BB) panels feature bifacial cells, and do they collect light from both sides? No, the DHM-60X10/FS(BB) series consists of monofacial modules, meaning they are single-sided. Electrical energy is generated exclusively from the front glass-covered surface. If dual-sided irradiance collection is a priority — for example, on high-albedo surfaces or ground-mounted systems — bifacial models from DAH Solar or other Tier 1 manufacturers should be considered instead. ### Are DAH Full Screen DHM-60X10/FS(BB) modules rated for snow loads and high wind pressure? Yes, the DHM-60X10/FS(BB) series offers high mechanical resistance: it is rated for snow loads up to 5,400 Pa and wind loads up to 2,400 Pa. This makes the modules well suited for the Polish climate, where significant snow accumulation during winter months is common. The rounded edge profile of the Full Screen design further reinforces the module structure and facilitates natural snow shedding without the need for manual intervention. ### What is the maximum power output of the DAH DHM-60X10/FS(BB) panel, and do the 1/3-cut cells improve performance under overcast conditions? The module's maximum power output is 455 Wp, with efficiency reaching approximately 21%. The use of 1/3-cut cells in combination with multi-busbar (MBB) technology featuring 10 busbars reduces internal resistive losses and minimizes the impact of partial shading on overall panel output. In practice, this translates to improved performance on cloudy days and under non-uniform irradiance conditions — a meaningful advantage given Poland's climate profile. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/EN-DHM-60X10-FS-BB-440-455W-bfba67063628.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, +3.9 pp, +5 yr warranty | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, +3.6 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +50 W, cooler, +3.6 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +50 W, cooler, +3.6 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +50 W, cooler, +3.6 pp | | [GCL GCL-NR10R/54BGDF](https://comparepv.com/panel/gcl-gcl-nr10r-54bgdf) | 500 W | +50 W, cooler, +3.6 pp | | [DAH Solar DHT-M60X10-430W](https://comparepv.com/panel/dah-solar-dht-m60x10-430w) | 430 W | -20 W, -0.9 pp | | [DAH Solar DHT-M60X10-435W](https://comparepv.com/panel/dah-solar-dht-m60x10-435w) | 435 W | -15 W, -0.7 pp | | [DAH Solar DHM-60X10/FS(BB)-440W](https://comparepv.com/panel/dah-dhm-60x10-fs-bb-440w) | 440 W | -10 W, -0.5 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 | +110 W, cooler, +3.9 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +105 W, cooler, +3.8 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +100 W, cooler, +3.5 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +90 W, cooler, +3.5 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +90 W, cooler, +3.5 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | +95 W, cooler, +3.4 pp | --- Source: https://comparepv.com/panel/dah-dhm-60x10-fs-bb-450 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
