TÜV Nord field studies confirmed an average monthly energy yield increase of 10.37% compared to standard PERC modules of equivalent rated power; under heavy soiling conditions, the manufacturer declares a gain of 6–15%. - **BNEF Tier 1 – Confirmed Bankability** - DAH Solar maintained Tier 1 status per Bloomberg NEF across all publicly confirmed quarters of 2025 (Q1, Q3, Q4). This designation ensures acceptance by financial institutions in project-financed installations and reduces the credit risk profile of the system. - **Up to 21.32% Efficiency in the 182 mm PERC Class** - For monocrystalline PERC technology, 21.32% represents the upper bound achievable within this cell class. The peer-comparable Zonergy ZPM MH3-72 (max. 460 Wp) reaches 21.16%, confirming that the DHM-60X10/FS(BW) series is competitive within the PERC segment. - **Rounded Frame Profile – Improved Logistics** - The rounded frame profile reduces the risk of edge damage during transportation and installation. The module is certified to IEC 61215 and IEC 61730, confirming compliance with mechanical load resistance requirements. - **25-Year Power Output Warranty** - A standard linear 25-year power warranty with a declared retention of ≥84.8% of nominal power ensures predictable energy yield throughout the full typical service life of residential or commercial installations. ## Cons - **Discontinued Product Line** - The DHM-60X10/FS(BW) series is officially discontinued. This results in limited availability on the secondary market, no production batch continuity for system expansions, and potential difficulties obtaining warranty replacements once distributor inventory is exhausted. - **PERC Technology Being Displaced by TOPCon** - Peer-comparable modules — Risen RSM96-11-440-460BNDG and SunKean SKT440~460M12-96D4 — achieve efficiencies of 23.00–23.02% at the same 460 Wp rating, indicating the use of N-type TOPCon cells. This represents an efficiency advantage of 1.7–2.4 percentage points over this series' maximum (21.32%), translating into meaningfully higher energy yield per unit of roof area. - **Product Warranty of Only 12 Years** - The product warranty covers 12 years, whereas leading Tier 1 manufacturers (e.g., Risen, Jinko, LONGi) routinely offer 15–25 years of product warranty on current series. The shorter coverage period increases the financial risk associated with early mechanical failures or manufacturing defects. ## About this series The DAH DHM-60X10/FS(BW) series is designed to realistically minimize energy loss under the most common conditions that "sabotage" rooftop energy production. The **Full Screen** concept reduces dirt accumulation and facilitates water runoff, allowing the module to operate stably for longer periods without frequent cleaning. This provides a practical solution to the problem of dust, leaves, and debris that can reduce the efficiency of the entire system. It is also distinguished by its **rounded profile frame**, which improves mechanical strength and simplifies transportation and installation. Combined with **monocrystalline technology** and a split-cell configuration, the series is better able to cope with localized shading and reduces the risk of overheating of individual cells. The **sleek black aesthetic**, which is highly valued in modern designs, completes the package. This is a good choice for residential and commercial installations, especially where a clean appearance, reliability in harsh conditions, and predictable energy output over the years are important. ## Notable figures - Efficiency of 20.6% matches the \*\*PERC 400-450W\*\* median - At 206.2 W/m² power density, roof space requirements are typical for \*\*PERC 400-450W\*\* panels - Temperature coefficient of -0.35%/°C matches the \*\*PERC 400-450W\*\* median - Weight of 23.8 kg is 1.8 kg above \*\*PERC 400-450W\*\* median (22.0 kg) - verify structural support - In the top 79% for efficiency among all PERC panels ## Questions ### Is the DAH Solar DHM-60X10/FS(BW) series still available for purchase? The DHM-60X10/FS(BW) series has been discontinued and is no longer available through regular supply channels. Isolated units may occasionally surface from distributor inventory, but these should not be relied upon when planning a larger installation. If you are looking for a module with similar specifications and Full Screen aesthetics from DAH Solar, it is advisable to inquire about currently manufactured series from the same vendor. ### What warranty is provided for DAH Solar DHM-60X10/FS(BW) 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 guaranteed to retain a specified percentage of its nominal power rating over 25 years. These are standard warranty terms for Tier 1 panels and provide confidence in the long-term energy yield of the installation. ### What does the Full Screen technology in the DAH Solar DHM-60X10/FS(BW) panels mean, and does it genuinely help keep the surface clean? Full Screen refers to a frameless front-side design that eliminates the horizontal edges found on conventional framed modules — edges where dust, leaves, and other debris typically accumulate. As a result, rainwater flows more freely across the surface, washing away deposits more effectively, and the module sustains stable output power for longer periods without requiring manual cleaning. In climates such as Poland's, where rooftops are often partially shaded by trees or neighboring buildings, this translates into a measurable improvement in annual energy yield. ### Do the DHM-60X10/FS(BW) panels handle partial shading from a chimney or antenna well? Yes, the series employs a half-cut cell layout, which significantly limits the impact of localized shading on overall module output. When a portion of the cells is shaded by a chimney, antenna, or adjacent panel, the remaining cell sections continue to operate at the highest power level possible. While this does not eliminate shading losses entirely, it substantially reduces their scope compared to a conventional full-cell module architecture. ### What is the maximum power output of the DAH Solar DHM-60X10/FS(BW) panel, and is it sufficient for a residential installation? The module achieves a peak output of up to 460 Wp under STC conditions. For a typical single-family home consuming 4,000–5,000 kWh per year, 8 to 12 such panels are generally sufficient, depending on roof orientation and geographic location. A 460 Wp power class is considered high-tier, enabling the target system capacity to be reached with fewer modules — a distinct advantage on rooftops with limited available area. ### Is DAH Solar a trustworthy manufacturer, and where is it based? DAH Solar is a Chinese manufacturer classified as Tier 1 by Bloomberg NEF, meaning it meets the rigorous financial and production criteria applied by market analysts. The company has been in operation for more than two decades and supplies modules to European markets, including Poland. Tier 1 status is particularly relevant when seeking project financing and when verifying the enforceability of warranty terms. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/EN-DHM-60X10-FS-BW-445-460W-003d862a3f1f.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +50 W, cooler, +4.2 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, +3.9 pp, +5 yr warranty | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | Cooler, +3.9 pp, +5 yr warranty | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | Cooler, +3.7 pp, +5 yr warranty | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | Cooler, +3.7 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-495M](https://comparepv.com/panel/longi-lr7-54hjd-495m) | 495 W | +50 W, cooler, +3.7 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | Cooler, +3.7 pp, +5 yr warranty | | [DAH Solar DHT-M60X10-430W](https://comparepv.com/panel/dah-solar-dht-m60x10-430w) | 430 W | -15 W, -0.7 pp | | [DAH Solar DHT-M60X10-435W](https://comparepv.com/panel/dah-solar-dht-m60x10-435w) | 435 W | -10 W, -0.5 pp | | [DAH Solar DHM-60X10/FS(BB)-440W](https://comparepv.com/panel/dah-dhm-60x10-fs-bb-440w) | 440 W | -0.2 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +115 W, cooler, +4.2 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +110 W, cooler, +4.0 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +105 W, cooler, +3.8 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +95 W, cooler, +3.8 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +95 W, cooler, +3.8 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | +100 W, cooler, +3.6 pp | --- Source: https://comparepv.com/panel/dah-dhm-60x10-fs-bw-445w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
