The 0.06–0.11 pp/°C difference translates into measurably higher energy yield on hot, sunny days when module temperature exceeds 50–60°C. - **30-year power warranty at ≥87.4%** - DAH guarantees at least 87.4% of nominal power output after 30 years of operation, with annual degradation ≤0.4% from year 2 onward (year 1 ≤1%). Most comparable Tier-1 models cap their warranty at 25 years; the extended warranty horizon improves the financial performance of both residential prosumer and commercial projects. - **~85% bifaciality with double-glass construction** - The module's rear surface generates additional yield from reflected irradiance (albedo), particularly valuable in ground-mounted installations and on high-reflectivity surfaces. The double-glass design eliminates the rear backsheet, improving resistance to moisture, ammonia, and mechanical loads compared to standard monofacial modules. - **BNEF Tier 1 – confirmed bankability** - DAH Solar has continuously appeared on the BNEF Tier 1 list at least since Q1 2025 (confirmed Q1 and Q3 2025). This status is required by the majority of banks and leasing companies when financing PV installations, and is absent from several competitors in this price segment. - **Efficiency up to 22.71% – at the top of the 490 Wp segment** - The maximum efficiency of 22.71% matches the segment leader among directly comparable models (Renesola RS4-490NX-E1: 22.71%) and exceeds the Horay Solar HS 182-120 TC (22.6%). This allows the same installed capacity to be achieved on a smaller roof area. ## Cons - **Weight ~26 kg (DG variant)** - The double-glass construction raises module weight to approximately 26 kg, compared to ~21–22 kg for typical monofacial modules of equivalent power. On steep-pitch roofs and older mounting structures, a structural load assessment may be required, and single-person installation becomes more difficult. ## About this series The DAH DHN-60X16/DG 475-490W series has been designed to maximize energy yield on rooftops or on the ground, where every square meter counts. A key advantage is the combination of **n-type TOPCon** cells with a **double glass** construction, which translates into improved operational stability and higher resistance to typical installation issues. The modules stand out due to **lower degradation** and strong protection against PID (Potential Induced Degradation), making it easier to maintain high energy production for subsequent seasons. In addition, their **good performance at high temperatures** and effective use of diffuse light are beneficial in Polish weather conditions, where cloudy skies are common. This makes them a reasonable choice for installers and investors seeking panels for residential homes, businesses, and modern prosumer projects, where predictability, durability, and cost-effectiveness are key considerations, without incurring additional marketing expenses. ## Notable figures - At 22.2% efficiency, this panel is on par with typical \*\*TOPCon 450-500W\*\* modules - Power density of 222.4 W/m² matches the \*\*TOPCon 450-500W\*\* median - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 450-500W\*\* panels - Weight of 26.0 kg is 2.0 kg above \*\*TOPCon 450-500W\*\* median (24.0 kg) - verify structural support - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### What warranty is provided for the DAH Solar DHN-60X16/DG 475–490W series? The DHN-60X16/DG series is backed by a 25-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty. The degradation terms are highly favorable: no more than 1% power loss in the first year and a maximum of 0.4% per year thereafter. After 30 years, the module is guaranteed to retain at least 87.4% of its nominal power output, making this series exceptionally cost-effective over a long investment horizon. ### What is TOPCon technology and why does it matter in the DAH Solar DHN-60X16/DG modules? TOPCon (Tunnel Oxide Passivated Contact) is a next-generation n-type cell technology that delivers higher efficiency — up to 22.71% for this series — and a lower degradation rate compared to conventional PERC cells. In practical terms, this translates to greater energy yield from the same roof area and improved long-term performance stability throughout the full 30-year power warranty period. DAH Solar reports an energy production gain of more than 3% relative to PERC modules of equivalent nominal power. ### Are the DAH Solar DHN-60X16/DG 490W modules bifacial, and does that make sense for installations in Poland? Yes, the DHN-60X16/DG series features bifacial construction with a bifaciality factor of up to 85%, meaning the rear glass surface also generates power from reflected irradiance. In Poland, bifacial gain is most relevant for ground-mounted systems installed above high-albedo surfaces such as gravel, concrete, or snow cover in winter, as well as flat-roof installations with adequate rear clearance. On conventional pitched roofs, the bifacial yield gain is marginal; however, the double-glass construction itself enhances module durability and longevity regardless of mounting orientation. ### How do the DAH Solar DHN-60X16/DG 475–490W modules perform under Polish weather conditions, particularly in overcast conditions? The n-type TOPCon cells feature a low temperature coefficient of power at -0.29%/°C, resulting in smaller thermal losses during hot weather compared to older PERC modules. Additionally, this cell technology exhibits superior conversion of diffuse irradiance, which is prevalent in the Polish climate. The practical outcome is meaningfully better energy yields in spring, autumn, and under overcast skies — conditions that account for a significant portion of the year in Poland, where clear-sky days are relatively scarce. ### What are the dimensions and weight of the DAH Solar DHN-60X16/DG modules, and will they fit on a small roof? The modules measure 1903 × 1134 × 30 mm and weigh approximately 26 kg. The 30 mm frame depth results from the double-glass construction. When planning an installation on a small roof, note that each panel occupies approximately 2.16 m². For a typical single-family home with a 10 kW system, around 20–21 panels are required, covering approximately 43–45 m² of roof surface. ### Is the DAH Solar DHN-60X16/DG series resistant to PID, and does that matter for high-voltage systems? Yes, the manufacturer declares excellent resistance to PID (Potential Induced Degradation). PID is a particular concern in large string systems operating at high system voltages, where it can cause permanent power losses of up to several percent. The combination of PID resistance, n-type TOPCon cell technology, and double-glass construction makes the DHN-60X16/DG series well suited for both residential installations and larger commercial projects, without the risk of accelerated voltage-induced degradation over the system's lifetime. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/en-dhn-60x16-dg-475-490w-82770c485127.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +30 W, cooler, +2.8 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +2.6 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +25 W, cooler, +2.5 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +2.3 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +2.3 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | Cooler, lighter, +2.3 pp | | [DAH Solar DHT-M60X10-430W](https://comparepv.com/panel/dah-solar-dht-m60x10-430w) | 430 W | -50 W, hotter, -2.3 pp | | [DAH Solar DHT-M60X10-435W](https://comparepv.com/panel/dah-solar-dht-m60x10-435w) | 435 W | Hotter, -2.1 pp, -5 yr warranty | | [DAH Solar DHM-60X10/FS(BB)-440W](https://comparepv.com/panel/dah-dhm-60x10-fs-bb-440w) | 440 W | Hotter, -1.8 pp, -5 yr warranty | | [DAH Solar DHM-60X10/FS(BW)-445W](https://comparepv.com/panel/dah-dhm-60x10-fs-bw-445w) | 445 W | Hotter, -1.6 pp, -5 yr warranty | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +80 W, cooler, +2.6 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +75 W, cooler, +2.4 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +70 W, lighter, +2.2 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +60 W, cooler, +2.2 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +60 W, cooler, +2.2 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | +65 W, cooler, +2.0 pp | --- Source: https://comparepv.com/panel/dah-dhn-60x16-dg-bw-480w Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
