Over a 30-year operating horizon, the cumulative difference translates into a measurably 3–5% higher total energy yield. - **695–715 Wp Power Output on Par with Top Peer Comparables** - The 132-cell G12 format achieves up to 715 Wp at 23.0% efficiency, placing it on par with direct competitors (New East Solar NESE 66THB-G12: 715 Wp / 23.02%; BECSA BEC-HJT: 715 Wp / 23.0%). The high per-module wattage reduces the total number of modules required and lowers BoS costs (cabling, racking), particularly in commercial and ground-mounted installations. - **Bifacial Dual-Glass Construction** - A bifaciality factor of up to 80% enables an additional 5–25% energy gain from ground-reflected irradiance depending on albedo. The glass-glass construction eliminates backsheet degradation risk and EVA corrosion, while the mechanical load ratings — 5,400 Pa snow load, 2,400 Pa wind load — are well suited to Polish climatic conditions, including winter structural loads. - **30-Year Linear Power Output Warranty** - The manufacturer guarantees degradation of ≤1.0% in year 1 and ≤0.40%/year in years 2–30, ensuring a minimum of ~87.4% Pnom after the full 30-year period. Many competing modules offer only a 25-year power warranty with a threshold of ~84.8% Pnom, making this series distinctly more advantageous for projects underwritten over a full depreciation cycle. - **BNEF Tier 1 – Four Consecutive Quarters (2025)** - DAS Solar has maintained BloombergNEF Tier 1 status across all four quarters of 2025. This qualification requires documented participation in at least six projects >10 MW financed by independent commercial banks within a 24-month period, directly confirming the manufacturer's bankability for large-scale project financing. ## Cons - **Large Format – Installation Constraints** - Module dimensions of 2,384 × 1,303 mm and a weight of 37.1 kg per unit effectively preclude use on small residential rooftops with limited load-bearing capacity or narrow roof sections. Installation requires a minimum two-person crew or mechanical handling equipment, which increases the unit labor cost in prosumer projects compared to lighter 182 mm (M10) format modules. ## About this series Panels from the DAH DAS-DH132NC series introduce a new quality to the Polish market thanks to a unique patented design that directly affects the energy yields of the entire system. The most important innovation distinguishing this series is **Full-Screen technology**, characterized by the absence of a protruding frame at the edges. This solution effectively eliminates the problem of water, dust, and dirt accumulation, which in standard modules often leads to the formation of hot-spot phenomena and significant performance drops. The use of modern **N-Type TOPCon cells** ensures that these panels are characterized by an excellent temperature coefficient and increased resistance to degradation, which is key to maintaining efficiency for many years. An additional advantage is the **bifacial design**, allowing for the effective use of light reflected from the ground, which makes this series an optimal choice for demanding ground-mounted installations and large commercial systems. The DAS-DH132NC solves the common problem of power losses resulting from dirt settling near the frames, which significantly reduces maintenance costs and the frequency of system cleaning. Thanks to **high mechanical resistance** and the absence of dead zones on the surface, these modules ensure a maximum return on investment even in variable weather typical for Poland, offering a clear technological advantage over traditional competitive solutions. ## Notable figures - Efficiency of 22.7% matches the \*\*TOPCon 700-750W\*\* median - 226.9 W/m² power density is 3.2 W/m² below \*\*TOPCon 700-750W\*\* median (230.2 W/m²) - requires larger installation area - Temperature coefficient of -0.28%/°C matches the \*\*TOPCon 700-750W\*\* median - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces - In the top 24% for efficiency among all TOPCon panels ## Questions ### What warranty is offered on the DAS Solar DAS-DH132NC panels? The DAS-DH132NC series comes with a 15-year product (materials and workmanship) warranty and a 30-year power output warranty. The manufacturer guarantees that after 30 years of operation the module will retain at least 87.4% of its nominal power. The annual degradation rate is just 0.40%, which is well above average by industry standards and is a direct result of the N-Type TOPCon cell technology used in this series. ### What is the Full-Screen technology in the DAS-DH132NC panels, and does it actually make a difference? Full-Screen technology means the module has no protruding aluminum frame along its edges. In practice, this eliminates the spots where water, dust, and bird droppings accumulate — the primary causes of hot-spot formation in conventional framed modules. Field tests conducted by TÜV Nord confirm higher energy yield compared to standard framed modules. The benefit is especially pronounced in low-tilt installations, where soiling does not drain away by gravity. ### Are the bifacial DAS-DH132NC panels worth installing in ground-mounted systems in Poland? Yes, the 80% bifaciality factor makes the DAS-DH132NC modules an excellent fit for ground-mounted installations. Polish grass, light-colored gravel, or snow reflect irradiance onto the rear side of the panel, generating an additional 20–30% of energy compared to monofacial equivalents. The highest gain is achieved on structures with an adjustable tilt angle, where the rear surface is fully exposed and not shaded by vegetation. ### What is the temperature coefficient of the DAS-DH132NC panels, and do they perform well in summer? The N-Type TOPCon cells in the DAS-DH132NC series have a temperature coefficient of -0.28%/°C — significantly better than the typical -0.35%/°C of older P-Type PERC cells. This means that on a hot day when the panel heats up to 65°C (i.e., 40°C above the STC reference temperature), it loses only about 11% of its power output rather than 14%. In Poland's climate, with its increasingly hot summers, this translates into a measurably higher annual energy yield. ### Are the DAS Solar DAS-DH132NC panels suitable for rooftop installation on a single-family home? The DAS-DH132NC module, rated at 715 W and measuring 2384 × 1303 mm, weighs 37.1 kg. Due to its large format, it is primarily recommended for ground-mounted and commercial installations. Rooftop mounting on a pitched roof is possible but requires a reinforced racking structure and an experienced installation crew. For typical residential prosumer rooftops, the smaller modules within the same series — rated at 695–705 W — may be a more practical choice. ### Is DAS Solar a reliable manufacturer, and do the DAS-DH132NC panels carry the necessary certifications? DAS Solar is a Tier 1 manufacturer, listed by leading PV industry rating agencies, which reflects the company's financial stability and the bankability of projects using its products. The DAS-DH132NC series modules hold IEC 61215 and IEC 61730 certifications — the most important international standards for photovoltaic module performance and safety — as well as ISO 9001, ISO 14001, and ISO 45001. The products have passed triple-round IEC testing, confirming their reliability under demanding weather conditions. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/DAS-DH132NC-EN-695-715-c4c28b3ca723.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | -25 W, lighter, +2.5 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | -30 W, lighter, +2.3 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Cooler, lighter, +2.3 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Cooler, lighter, +2.2 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | -35 W, lighter, +2.1 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | -35 W, lighter, +2.1 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | -35 W, lighter, +2.1 pp | | [DAH Solar DAS-DH132NC-695](https://comparepv.com/panel/dah-solar-das-dh132nc-695) | 695 W | -10 W, -0.3 pp | | [DAH Solar DHN-66Y18/DG-700](https://comparepv.com/panel/dah-dhn-66y18-dg-700) | 700 W | Lighter | | [DAH Solar DHN-66Y18/DG-710](https://comparepv.com/panel/dah-dhn-66y18-dg-710) | 710 W | Lighter | | [DAH Solar DHN-66Y18/DG-715](https://comparepv.com/panel/dah-dhn-66y18-dg-715) | 715 W | +10 W, lighter, +0.3 pp | | [DAH Solar DHN-66Y18/DG-720](https://comparepv.com/panel/dah-dhn-66y18-dg-720) | 720 W | +15 W, lighter, +0.5 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +100 W, cooler, +2.4 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +95 W, cooler, +2.2 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +90 W, cooler, +2.1 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +85 W, cooler, +1.9 pp | --- Source: https://comparepv.com/panel/dah-solar-das-dh132nc-705 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.
