Natural rain self-cleaning reduces the risk of hot spots and production losses caused by soiling-induced partial shading. - **N-type TOPCon – Low Degradation and High Energy Yield** - N-type TOPCon cells exhibit significantly lower light-induced degradation (LID) than legacy PERC technology, along with superior performance at elevated temperatures and under diffuse low-irradiance conditions. This translates into a measurably higher annual energy yield under Polish climatic conditions compared to PERC-based modules. - **Bifacial Design with Dual-Glass Construction** - The module harvests energy from both faces — the rear glass layer (replacing a conventional backsheet) delivers long-term durability and moisture resistance. On high-albedo surfaces (albedo >25%), a bifaciality factor of approximately 85% can contribute an additional 5–15% annual energy yield relative to monofacial modules. - **30-Year Linear Power Output Warranty** - DAH Solar provides a 30-year linear power output warranty, one of the longest warranty terms available in this segment. By comparison, many Tier-2 models offer only a 25-year power warranty. An extended warranty horizon is critical for project finance bankability and LCOE calculations on commercial-scale installations. - **Confirmed BNEF Tier 1 Status** - DAH Solar appears on the BNEF Tier 1 PV Module Manufacturers list across consecutive quarters in 2025 (Q1, Q3, Q4 2025), confirming bankability and enabling access to project financing without the additional credit enhancements typically required for lower-tier manufacturers. ## Cons - **Efficiency Below Top-Tier Peer Comparables** - The series reaches a maximum efficiency of 22.7%, while direct competitors achieve measurably higher values — Jinko Tiger Neo 66HL4M at 23.51% and LONGi Hi-MO X10 LR7-72HVD at 23.5% — a gap of approximately 0.8 percentage points. On roof installations with limited available area, this results in a lower peak power density per m². - **15-Year Product Warranty** - The product warranty covering manufacturing defects and workmanship is only 15 years, whereas leading Tier-1 manufacturers — LONGi, Jinko, and Trina — standardly offer a 25-year product warranty in this segment. The shorter coverage period may be a material concern in long-term project financing or leasing arrangements. ## About this series DAH Bifacial Double Glass Module N-Type series photovoltaic panels are a breakthrough solution that effectively eliminates one of the biggest problems of traditional installations - the accumulation of sediment and water on the module edges. Thanks to the use of unique, patented **Full Screen** technology, which features a completely frameless design on the front side, contaminants are naturally removed by rainfall. This approach drastically reduces the risk of harmful hot-spots and allows for significantly higher electricity production on an annual basis. The use of advanced **N-type cells in TOPCon technology** translates into higher efficiency in low light and exceptional resistance to light-induced degradation. Additionally, the **bifacial double glass** design enables active energy generation from both sides of the panel, which is particularly beneficial for systems mounted on bright surfaces with a high albedo coefficient. This series stands out from the competition with its excellent **resistance to the PID effect** and extreme weather conditions, such as strong winds or snow loads. It is an ideal choice for investors focusing on the highest reliability, fire safety, and **maximizing profit per unit of area**. These modules are perfect for both aesthetic home installations and large-scale commercial projects, ensuring peace of mind and the highest yields for decades. ## Notable figures - At 21.8% efficiency, this panel is 1.0pp below the \*\*TOPCon 600-650W\*\* median of 22.8% - Power density of 218.2 W/m² is 9.5 W/m² below \*\*TOPCon 600-650W\*\* median (227.7 W/m²) - needs more roof space - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 600-650W\*\* median - At 34.3 kg, this panel is 1.6 kg heavier than the \*\*TOPCon 600-650W\*\* median (32.7 kg) - more demanding for installation crews - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### What is Full Screen technology in DAH Solar Bifacial Double Glass N-Type panels and why does it matter? Full Screen technology means the module has no aluminum frame on its front face. As a result, dirt, dust, and rainwater flow freely off the panel surface instead of accumulating along the edges. In practice, this translates to a reduced risk of hot-spot formation and higher annual energy yields without the need for frequent system cleaning. This solution is patented by DAH Solar. ### What warranty comes with DAH Solar Bifacial Double Glass N-Type panels? The manufacturer offers a 15-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty. The power warranty guarantees that after 30 years of operation the panel will retain the manufacturer-specified percentage of its nominal power. This is one of the longest power warranty standards available on the market, typical of N-type TOPCon modules. ### Are DAH Solar Bifacial Double Glass N-Type panels suitable for ground-mounted installations on gravel or white membrane roofing? Yes, the bifacial double-glass construction is particularly cost-effective in ground-mounted and flat-roof installations where the surface beneath — light-colored gravel, white membrane, or concrete — reflects a significant portion of solar irradiance. The rear side of the panel actively generates energy from this reflected radiation, which can increase the overall system yield by up to several percentage points compared to a standard monofacial module. ### What is the maximum power output of a DAH Solar Bifacial Double Glass N-Type panel, and is that high for a module of this format? The top variant in the series reaches 635 Wp, placing these modules firmly in the premium high-power segment. The high per-module power is a result of the N-type TOPCon cells, which offer superior conversion efficiency compared to older P-type PERC cells. Consequently, fewer modules are required to achieve the same total system power, reducing installation costs and roof area consumption. ### Do DAH Solar N-Type TOPCon panels perform well on cloudy days and in low-light conditions? Yes, N-type TOPCon cells demonstrate better low-light performance compared to conventional P-type cells. A low temperature coefficient (approximately -0.29%/°C) also means the modules lose less power on hot days. In practice, this results in higher energy yields throughout the year — both in summer and during the overcast autumn and winter days typical of the Polish climate. ### Is DAH Solar a reliable manufacturer and are the Bifacial Double Glass N-Type panels certified? DAH Solar is a Tier 1 manufacturer according to the BloombergNEF classification, which represents the highest category of financial and manufacturing reliability in the photovoltaic market. The company is publicly listed and operates large-scale production facilities in China. The Bifacial Double Glass N-Type series modules carry the standard certifications required for the European market, including IEC 61215 and IEC 61730, and exhibit high resistance to the PID (Potential Induced Degradation) effect. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Datasheet_DAS-DH156NA-EN-615-6352465-1134-35-e7891087525e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +40 W, lighter, +3.4 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +3.2 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -50 W, lighter, +3.0 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, lighter, +3.0 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | Cooler, lighter, +2.8 pp | | [Longi Solar LR8-66HVD-660M](https://comparepv.com/panel/longi-lr8-66hvd-660m) | 660 W | +50 W, cooler, +2.6 pp | | [DAH Solar DAS-DH156NA-615](https://comparepv.com/panel/dah-solar-das-dh156na-615) | 615 W | Very close match | | [DAH Solar DHN-78X16/DG-620W](https://comparepv.com/panel/dah-dhn-78x16-dg-620w) | 620 W | +10 W, cooler, +0.4 pp | | [DAH Solar DHN-78X16/DG-625W](https://comparepv.com/panel/dah-dhn-78x16-dg-625w) | 625 W | +15 W, cooler, +0.6 pp | | [DAH Solar DHN-78X16/DG-630W](https://comparepv.com/panel/dah-dhn-78x16-dg-630w) | 630 W | +20 W, cooler, +0.7 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +70 W, lighter, +3.4 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +65 W, lighter, +3.2 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +90 W, cooler, +3.2 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +85 W, cooler, +3.1 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +60 W, lighter, +3.0 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +60 W, lighter, +3.0 pp | --- Source: https://comparepv.com/panel/dah-solar-das-dh156na-610 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.
