For commercial installations and utility-scale PV farms, this is a critical criterion for project finance eligibility. - **30-Year Linear Power Warranty – 84.95%** - The manufacturer guarantees a minimum of 84.95% of nominal power output after 30 years, with an annual degradation rate of 0.45% following the first year. Peer comparables in this class (Exiom, Goldi Solar) offer equivalent warranty terms; however, some lower-cost competitors limit coverage to 25 years — a meaningful advantage for projects with a 25+ year investment horizon. - **Double-Glass Construction with Up to 70% Bifaciality** - A bifaciality factor of up to 70% translates into additional energy yield of approximately 5–25%, depending on ground albedo (light soil, gravel, snow). Dual-glass encapsulation eliminates the risk of EVA and backsheet degradation and statistically extends module service life — a significant consideration within the 30-year warranty window. - **Half-Cut PERC: Reduced Shading Losses** - The 144 half-cut cell architecture reduces the operating current in each cell half by 50%, lowering resistive losses and mitigating hot-spot formation. In practice, the modules perform better under partial inter-row shading in large ground-mount arrays, resulting in higher annual energy yield compared to full-cell equivalents. - **Up to 560 Wp Output, Up to 21.7% Efficiency** - The top-tier 560 Wp variant achieves 21.7% module efficiency — identical to the best peer comparables in this class (Exiom EX560M, Goldi Solar GS10-B144-GF). The series ranks among the leaders in the P-type bifacial 144HC segment in terms of power density, without the cost premium associated with N-type technology. ## Cons - **PERC Technology Trails TOPCon in Thermal Performance** - The temperature coefficient of P-type PERC cells is -0.35%/°C, compared to -0.31%/°C for TOPCon modules available from competitors at the same price point. In Central European climates, this difference translates to approximately 0.5–1% lower annual energy yield on high-irradiance days when module temperature exceeds 45°C. - **Higher LID and Lower Bifaciality vs. TOPCon** - P-type PERC cells exhibit first-year light-induced degradation (LID) of approximately 2%, versus ~1% for N-type TOPCon, and a bifaciality factor of up to 70% compared to 80%+ in TOPCon modules at the same price tier. DAS Solar's own portfolio includes newer N-type series (DAS-DH144NA), suggesting the DH144PA series represents previous-generation technology. - **Limited Manufacturer Track Record (Est. 2018)** - DAS Solar has been operating since 2018, representing approximately seven years of operational history. Given a 30-year power warranty, lenders and insurers may require additional credit enhancements — such as a surety bond or parent guarantee — compared to manufacturers with 15–20 years of market presence. ## About this series The DAS Solar DAS-DH144PA series is designed as **bifacial modules in double-glass construction**, enabling them to effectively utilize reflected light and operate more reliably in demanding installation conditions. The glass on both sides increases resistance to environmental factors and minimizes the risk of micro-cracks and accelerated aging - a practical advantage where longevity and predictable energy yields over years are key. A key feature of this series is the combination of **P-type cells** with a bifacial generation architecture and **half-cut technology**, which reduces mismatch losses. In practice, this means better performance under partial shading between rows, greater production stability in varying sunlight conditions, and easier design of large module areas. The DAS-DH144PA is an excellent choice for ground installations and large commercial rooftops, where the **additional yield from the rear side** and mechanical durability are crucial. Compared to competitors, this series stands out by emphasizing the long-term reliability of the dual-glass construction and optimizing performance in less-than-ideal conditions. ## Notable figures - Efficiency of 20.9% matches the \*\*PERC 500-550W\*\* median - At 209.0 W/m² power density, roof space requirements are typical for \*\*PERC 500-550W\*\* panels - At -0.34%/°C, hot weather performance is typical for \*\*PERC 500-550W\*\* panels - Weight of 31.4 kg is 3.0 kg above \*\*PERC 500-550W\*\* median (28.4 kg) - verify structural support - 70% bifaciality enables rear-side power generation, boosting yield by 4-10% on reflective surfaces ## Questions ### What warranty is offered on DAS Solar DAS-DH144PA panels? The DAS-DH144PA series comes with a 15-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty. The manufacturer guarantees at least 87.4% of nominal power after 10 years and a minimum of 80% after 30 years. This is one of the longest warranty packages available in the P-type PERC module segment, making it a reliable choice for long-term installations. ### Are DAS-DH144PA panels suitable for ground-mounted utility-scale solar farms? Yes, the DAS-DH144PA series is designed primarily for ground-mounted installations and large commercial rooftops. The double-glass construction provides high mechanical strength and weather resistance, while a bifaciality factor of up to 70% enables additional energy yield from reflected irradiance off the ground surface. The module dimensions of 2278×1134 mm and a weight of 31.4 kg require a robust mounting structure, which is standard for ground-mount installations. ### What does half-cut PERC technology mean in the DAS-DH144PA series, and why does it matter? Half-cut cell technology splits each PERC cell into two halves, reducing the operating current and the associated resistive losses. In practice, a 144 half-cut cell panel handles inter-row partial shading more effectively, maintains more stable output under overcast conditions, and generates less heat. For the end user, this translates into genuinely higher annual energy yield under real-world operating conditions, not just under laboratory test conditions. ### How much additional energy does the bifaciality of DAS-DH144PA panels deliver? The bifaciality of the DAS-DH144PA series reaches up to 70%, which under favorable conditions can translate into up to 25% more energy compared to an equivalent monofacial module. The actual gain depends on the mounting height above the ground, the albedo of the surface beneath, and the angle of incident irradiance. The best results are achieved on high-albedo surfaces such as concrete or gravel in ground-mounted installations with adequate clearance above the ground. ### Is DAS Solar a reliable manufacturer, and is the DAS-DH144PA series still available? DAS Solar is a Chinese manufacturer recognized as Tier 1 by independent market analysts, confirming its financial stability and manufacturing capacity. The DAS-DH144PA series is currently available for purchase and has not been discontinued. Modules in this series with power outputs of up to 560 Wp can be sourced from European distributors, including those operating in Poland. ### What is the efficiency of the DAS Solar DAS-DH144PA 560W module, and how does it compare to the market? The DAS-DH144PA 560W model achieves a module efficiency of up to 21.7%, which is a solid result for P-type PERC technology. For comparison, newer N-type TOPCon modules reach 22–23%, but at a higher purchase cost. The DAS-DH144PA series remains competitively priced in the large-format bifacial module segment intended for commercial and ground-mounted installations. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/das-dh144pa-en-540-560-ef-bc-882278-1134-30-ef-bc-89-e5006859b737.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +4.1 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +3.9 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +3.9 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +3.8 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +3.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +3.6 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +3.6 pp | | [DAS Solar DAS-DH144PA-545W](https://comparepv.com/panel/das-solar-das-dh144pa-545w) | 545 W | +0.2 pp | | [DAS Solar DAS-DH144PA-550W](https://comparepv.com/panel/das-solar-das-dh144pa-550w) | 550 W | +10 W, +0.4 pp | | [DAS Solar DAS-DH144PA-555W](https://comparepv.com/panel/das-solar-das-dh144pa-555w) | 555 W | +15 W, +0.6 pp | | [DAS Solar DAS-DH144PA-560W](https://comparepv.com/panel/das-solar-das-dh144pa-560w) | 560 W | +20 W, +0.8 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +110 W, cooler, +4.3 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +105 W, cooler, +4.1 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +100 W, cooler, +3.9 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +95 W, cooler, +3.7 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +90 W, cooler, +3.5 pp | --- Source: https://comparepv.com/panel/das-solar-das-dh144pa-540w 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.
