This places the module firmly among the highest-performing large-format panels currently available on the market. - **N-Type TOPCon: Degradation Rate –0.40%/Year** - N-type TOPCon cells exhibit an annual power degradation rate of –0.40% and a first-year LID of just –1.0%, compared to –~0.55%/year and –2–3% in the first year for standard P-type PERC modules. Over a 30-year project lifetime, the difference in cumulative energy yield can amount to several percentage points, with a direct impact on the project's LCOE. - **Bifacial Glass-Glass Construction, Bifaciality 80%** - The glass-glass construction with a bifaciality factor of up to 80% enables absorption of reflected albedo irradiance, which in ground-mounted applications (utility-scale PV farms, agrivoltaic systems) can translate into an additional 10–30% energy yield compared to monofacial modules. The dual-glass encapsulation also provides resistance to snow loads of 5,400 Pa and wind loads of 2,400 Pa, critical for projects in challenging climatic locations. - **30-Year Linear Power Output Warranty** - The manufacturer offers a 30-year linear power output warranty (alongside a 15-year product warranty), which meets the standard required for utility-scale project financing by banks and infrastructure funds. This confirms the module's bankability status: DAS Solar appears on the BNEF Tier 1 list and received an 'A' rating in the PV ModuleTech Bankability Ratings Q2 2025 report (PV Tech). - **Certified Bankability: BNEF Tier 1 + 'A' PV ModuleTech Rating** - Independent verification of financial credibility through two distinct methodologies — BloombergNEF Tier 1 (criteria: module supply to ≥6 projects ≥10 MW financed on a non-recourse basis by ≥6 banks) and an 'A' rating in PV ModuleTech Q2 2025 — reduces project risk and facilitates debt financing for large commercial installations. ## Cons - **Limited Manufacturer Track Record (Founded 2018)** - DAS Solar has been in operation for approximately 7 years while offering a 30-year power output warranty. By comparison, direct segment competitors such as Jinko Solar (2006), Trina Solar (1997), and Canadian Solar (2001) have significantly longer documented operational histories. For large externally financed projects (project finance), the manufacturer's short operational track record may be flagged as a risk factor during lender due diligence, despite the company's BNEF Tier 1 status. - **Module Weight ~37.1 kg — Limiting Factor for Rooftop Installations** - The glass-glass construction results in a module weight of approximately 37.1 kg, roughly 30–40% heavier than comparable glass-backsheet modules (approx. 26–28 kg). For rooftop applications, this requires structural load capacity assessment and often reinforcement of the mounting system, increasing the CAPEX of residential and commercial rooftop installations. The series is positioned by the manufacturer as dedicated to ground-mounted projects (utility-scale PV farms), where this factor does not represent a barrier. ## About this series Photovoltaic panels from the DAS-DH132NC series utilize advanced **N-type TOPCon cell technology**, which forms the foundation of their advantage over older P-type solutions. Thanks to the near-total elimination of light-induced degradation, these modules guarantee exceptionally stable energy production for many years, which directly translates into a faster return on investment. A key differentiator of this series is the **bifacial glass-glass design**, which ensures not only extreme resistance to external factors but also enables active energy harvest from both sides of the module. This solves the problem of limited performance in difficult conditions, offering a **high bifaciality factor** that outperforms single-sided counterparts in ground-mounted installations. This series also stands out for its **excellent efficiency under low light intensity**, which is critical for yields in the Polish climate, especially during transitional periods. The product is dedicated to large commercial projects and solar farms, where the priority is minimizing the LCOE cost. Robust construction and innovative cell architecture make the DAS-DH132NC a solution that sets new standards for durability and efficiency in modern photovoltaics, offering significantly higher yields than standard monocrystalline panels. ## Notable figures - At 22.7% efficiency, this panel is on par with typical \*\*TOPCon 700-750W\*\* modules - Power density of 226.9 W/m² is 3.2 W/m² below \*\*TOPCon 700-750W\*\* median (230.2 W/m²) - needs more roof space - At -0.28%/°C, hot weather performance is typical for \*\*TOPCon 700-750W\*\* panels - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces - #3307 for efficiency, #1309 for temperature performance out of 14005 panels ## Questions ### What warranty is provided for the DAS Solar DAS-DH132NC panels? The DAS-DH132NC series comes with a 15-year product warranty covering material and workmanship defects, as well as a 30-year linear power output warranty. Thanks to N-type TOPCon technology, the annual degradation rate is exceptionally low, meaning the module retains a significantly higher percentage of its nominal power after 30 years compared to legacy P-type cells. Both warranties are issued directly by the manufacturer, DAS Solar, which is classified as a Tier 1 module supplier. ### How does the N-type TOPCon technology used in the DAS-DH132NC series differ from standard P-type cells? The N-type TOPCon cells used in the DAS-DH132NC series exhibit near-zero susceptibility to LID (Light-Induced Degradation), a phenomenon that causes measurable power loss in conventional P-type cells within the first weeks of operation. This translates into higher module efficiency — up to approximately 23.2% — and consistently greater energy yields throughout the entire system lifetime, which directly reduces the LCOE in large-scale PV projects. ### Are the DAS-DH132NC panels suitable for commercial rooftop installations, or are they intended exclusively for ground-mounted PV farms? The DAS-DH132NC series, with a peak power output of up to 715 Wp and dimensions of 2384 × 1303 mm, is primarily designed for large commercial installations and utility-scale PV farms where minimizing LCOE is the primary driver. The module weight of approximately 37.1 kg requires a structurally robust rooftop mounting system. The bifacial glass-glass construction delivers its greatest yield gains in ground-mounted configurations where sufficient albedo reflection from the ground surface is available. ### What is the bifaciality factor of the DAS-DH132NC panels, and what does it mean in practice? The DAS-DH132NC panels achieve a bifaciality factor of up to 80%, meaning the rear side of the module generates up to 80% of the power produced by the front side. In ground-mounted installations or on highly reflective surfaces such as concrete, gravel, or snow, real-world energy yield can be 10–20% or more higher than that of a comparable monofacial module. This effect is especially pronounced in winter, when snow-covered ground reflects irradiance intensively onto the rear surface of the module. ### Do the DAS Solar DAS-DH132NC panels perform well under overcast conditions and in the Polish climate? Yes, the DAS-DH132NC series is optimized for low-irradiance operation, which is critical in Polish climatic conditions — particularly during autumn and winter. N-type TOPCon technology delivers superior low-light performance compared to P-type cells, enabling higher energy yields under diffuse irradiance. Additionally, the glass-glass construction withstands snow loads of up to 5,400 Pa and wind loads of up to 2,400 Pa, ensuring reliable and safe operation under demanding weather conditions. ### Are the DAS-DH132NC modules compatible with popular inverters such as SMA, Fronius, and Huawei? Yes, the DAS-DH132NC panels are equipped with Stäubli MC4 connectors, the industry-standard connector type, making them compatible with virtually all widely used inverter brands, including SMA, Fronius, Huawei, and SolarEdge. The maximum system voltage of 1,500 V allows for longer string configurations, which simplifies the electrical design of large commercial installations and utility-scale PV farms while reducing overall BoS costs. ## 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 | | [DAS Solar DAS-DH132NC-695](https://comparepv.com/panel/das-solar-das-dh132nc-695) | 695 W | -10 W, -0.3 pp | | [DAS Solar DAS-DH132NC-700](https://comparepv.com/panel/das-solar-das-dh132nc-700) | 700 W | Very close match | | [DAS Solar DAS-DH132NC-710](https://comparepv.com/panel/das-solar-das-dh132nc-710) | 710 W | Very close match | | [DAS Solar DAS-DH132NC-715](https://comparepv.com/panel/das-solar-das-dh132nc-715) | 715 W | +10 W, +0.3 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 | | [Trina Solar TSM-NEG21C.20Q-760](https://comparepv.com/panel/trina-solar-tsm-neg21c-20q-760) | 760 W | +55 W, cooler, +1.8 pp | --- Source: https://comparepv.com/panel/das-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.
