Efficiency leader, no clear weak spot
The DAS-DH108NA photovoltaic module series redefines efficiency standards thanks to the use of breakthrough N-type TOPCon cell technology. The bifacial double glass construction ensures that these panels absorb not only direct light but also energy reflected from the ground, which significantly increases real yields in ground-mounted and rooftop installations. The use of N-type cells eliminates the common problem of light-induced degradation, offering minimal power loss over time, translating into a longer lifespan for the entire installation. This series stands out from the competition with its excellent performance under low irradiance, allowing for power generation even on cloudy days. Thanks to the use of SMBB technology, these modules conduct current better and are less prone to the formation of harmful hot spots. It is an ideal solution for demanding residential users and commercial investors who want to maximize profits from every square meter of surface area. The solid, double-glass housing guarantees exceptional mechanical resistance to snow and wind loads, ensuring peace of mind for decades of operation. By choosing DAS-DH108NA, the investor opts for the highest build quality that effectively competes with premium segment brands, while offering unrivaled temperature stability during summer heatwaves.
Ranking
Signals from the data
Residential, commercial, cold-climate and hot-climate.
Top 1% of the TOPCon 400-450 W segment, against a median of 22.00%. Ranked 2,714th in the whole database.
Top 2% of the TOPCon 400-450 W segment, against a median of 220.2. Ranked 2,790th in the whole database.
Top 6% of the TOPCon 400-450 W segment, against a median of 51.4. Ranked 972nd in the whole database.
The -0.30%/°C temperature coefficient outperforms a typical PERC module (-0.34%/°C), translating into measurably higher energy yield during summer months — at a module temperature of 70°C, power loss is approximately 12% versus ~14.4% for PERC. N-type TOPCon cells also eliminate Light-Induced Degradation (LID), a phenomenon that can reduce output by 1–3% in P-type modules within the first weeks of operation.
The manufacturer guarantees degradation of ≤1% in year one and ≤0.4%/year from year two onward, ensuring ≥87.4% of rated output after 30 years. Peer comparables — Luxen LUXPOWER N5, ZNShine ZXM7-UHLDD108, and Solitek SOLID Blackstar — offer the same 435 Wp power class; the segment standard is 25–30 years, and DAS Solar sits at the upper end of that range.
The 435 Wp variant achieves 22.3% module efficiency, edging out direct peers: Luxen N5 and ZNShine ZXM7-UHLDD108 (both at 22.28%) and Solitek SOLID Blackstar (22.27%). SMBB (Super Multi Busbar) technology reduces series resistance and minimizes hot spot formation, helping sustain efficiency over the long-term operational horizon.
The dual-glass design (1.6 mm + 1.6 mm) with bifaciality up to 80% increases energy yield in ground-mounted systems by 5–15% compared to monofacial modules. The module carries IEC 61215, IEC 61730, IEC 61701 (salt mist corrosion resistance), and IEC 62716 (ammonia resistance) certifications, along with an IP68-rated connector and 3 bypass diodes — a complete compliance package for deployment in harsh environments.
DAS Solar appears on the BNEF Tier 1 PV Module Manufacturers list (confirmed at least through Q2 2025), meaning the manufacturer has independently financed at least six projects exceeding 10 MW within a 24-month period. Tier 1 status is a standard requirement for project finance on utility-scale PV farms and reduces the perceived investment risk compared to manufacturers outside the ranking.
DAS Solar has been operating since August 2018 — only 7–8 years in the market against the 30-year power warranty it provides. By comparison, Trina Solar was founded in 1997 and JA Solar in 2005. Institutional risk is partially mitigated by BNEF Tier 1 status and the backing of strategic investors (China Merchants, Three Gorges Capital); however, investors requiring a complete manufacturer financial history may need to conduct additional due diligence.
- 22.8% module efficiency - 0.8pp better than the TOPCon 400-450W median of 22.0%
- 227.9 W/m² power density - 7.7 W/m² more than TOPCon 400-450W median (220.2 W/m²), more power per roof area
- Temperature coefficient of -0.30%/°C matches the TOPCon 400-450W median
- 20.5 kg weight - 1.5 kg lighter than TOPCon 400-450W median (22.0 kg), reducing installation effort
- 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces
