Strong in heat, heavy for its output
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.
Ranking
Signals from the data
Utility-scale, commercial and hot-climate.
Weight-limited structures, roofs where every square metre has to count and tight roof space.
Top 11% of the TOPCon 700-750 W segment, against a median of -0.290.
Bottom 12% of the TOPCon 700-750 W segment, against a median of 52.9.
Bottom 21% of the TOPCon 700-750 W segment, against a median of 230.2.
Bottom 23% of the TOPCon 700-750 W segment, against a median of 23.00%.
N-type TOPCon technology delivers a degradation rate of ≤0.40%/year (years 2–30), compared to the typical ≤0.45–0.55%/year for PERC modules, along with a superior Pmax temperature coefficient (approx. -0.30%/°C vs. -0.35%/°C for PERC). Over a 30-year operating horizon, the cumulative difference translates into a measurably 3–5% higher total energy yield.
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.
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.
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.
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.
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.
- 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
