The DAS-DH108ND series consists of advanced photovoltaic modules utilizing N-type cell technology, which forms the foundation of modern and efficient solar energy. Thanks to the use of innovative TOPCon architecture, these panels offer significantly higher energy conversion efficiency than traditional P-type solutions. A key advantage of this series is its exceptional resistance to light-induced degradation, which guarantees stable electricity production for decades. The glass-glass design not only strengthens the module's mechanical structure, protecting it from extreme weather conditions, but also allows for the utilization of bifaciality. This means that the panels generate energy from both sides, maximizing yields especially on surfaces with high albedo. DAS-DH108ND is characterized by a low temperature coefficient, which ensures the system operates effectively even during hot summer days when standard panels lose efficiency. It is an ideal choice for investors seeking compact solutions for the roofs of single-family homes and commercial buildings, where every square meter of surface area counts. By choosing this series, you gain the assurance of long-term reliability confirmed by rigorous quality tests, placing the DAS Solar product at the forefront in terms of investment profitability in the Polish climate.

What owners get
N-type TOPCon – Higher Efficiency and Lower LID

N-type TOPCon cells exhibit near-zero light-induced degradation (LID <1%) and a low temperature coefficient (typically -0.30%/°C for TOPCon vs. -0.35%/°C for PERC). This translates into measurably higher annual energy yield in Poland's climate, which sees strong summer irradiance.

Efficiency Up to 22.5% – Above Market Average

The efficiency range of 21.6–22.5% places this series well above peer Zonergy ZPM MH3-72 (21.16%), delivering more power from the same roof area. For a 30 m² installation, this difference amounts to a real-world gain of approximately 10 Wp per module compared to lower-cost alternatives.

Glass-Glass Construction + Bifacial Design (Yield Gain Up to +30%)

The rear glass layer replaces the conventional EVA backsheet, extending module service life and eliminating the risk of encapsulant yellowing. The bifacial design enables additional energy harvest from the rear side — the manufacturer rates the power gain at up to 30% on high-albedo surfaces such as light gravel, snow, or light-colored metal roofing.

30-Year Power Output Warranty

The linear power output warranty covers a full 30 years, whereas 25 years remains the mid-range segment standard (e.g., Risen RSM96-11, Zonergy ZPM MH3-72). The extended warranty horizon reduces investment risk when structuring installations under lease agreements or project finance.

BNEF Tier 1 – Fourth Consecutive Quarter in 2025

DAS Solar maintained Tier 1 status according to BloombergNEF for four consecutive quarters in 2025 — a designation requiring six independent projects (minimum 10 MW each) financed on a non-recourse basis by six different banks. This status directly improves access to insurance products and project financing for commercial installations.

Trade-offs
Efficiency Below Segment Leaders

The maximum efficiency of 22.5% trails direct peer comparables by approximately 0.5 percentage points: Risen RSM96-11 (23.0%) and SunKean SKT440–460M12-96D4 (23.02%). For roof-constrained installations, this translates to a real-world shortfall of roughly 2–3 Wp per module relative to those alternatives.

Limited Manufacturer Track Record (Founded 2018)

DAS Solar has been in operation for only 7–8 years, whereas direct competitor Risen Energy has been manufacturing PV modules since 2002. The absence of a 20-year track record makes it harder to assess the manufacturer's long-term service quality and financial stability — a material consideration given the 30-year warranty horizon.

Common questions

6 answered
What warranty does the DAS Solar DAS-DH108ND series come with?
The DAS-DH108ND series is backed by a 25-year product warranty covering material and workmanship defects, along with a 30-year power output warranty. The power warranty guarantees that after 30 years of operation the panel will retain at least 87.4% of its nominal rated power. This power warranty term significantly exceeds the current market standard and reflects the manufacturer's high confidence in the long-term durability of N-type TOPCon cell technology.
Do the DAS-DH108ND panels perform efficiently during summer at high temperatures?
Yes. The DAS-DH108ND modules feature a low temperature coefficient, characteristic of N-type TOPCon cells, which means they experience smaller power losses as temperature rises compared to conventional P-type panels. In practice, on hot, sun-exposed residential rooftops, this series loses significantly less energy than older technologies, resulting in higher annual energy yields.
What does the glass-glass construction of the DAS-DH108ND series mean, and does it complicate installation?
Glass-glass construction refers to dual-glass encapsulation of the module in place of a traditional polymer backsheet. This design improves mechanical strength, provides superior moisture resistance, and extends the service life of the panel. The DAS-DH108ND module weighs approximately 21.7 kg with dimensions of 1800×1134×30 mm, which is well within industry norms. Installation does not require specialized mounting hardware, although a two-person installation crew is recommended, as it is for any module in this class.
How much additional energy do I gain from the bifacial design of the DAS-DH108ND panels?
The DAS-DH108ND panels capture light on both sides thanks to their transparent rear glass. On a typical light-colored or white surface — such as gravel, a white roofing membrane, or snow — the additional energy gain from the rear side is generally 5–15% relative to a conventional single-sided installation. The bifacial gain is more pronounced in ground-mounted systems with clearance beneath the modules than in flush roof-mounted configurations on dark roofing materials.
Is DAS Solar a reliable manufacturer, and is the DAS-DH108ND series still available in Poland?
DAS Solar (DAH Solar) appears on the Tier 1 lists published by leading industry analysts, confirming its financial stability and manufacturing quality. The DAS-DH108ND series is currently active and available on the Polish market through renewable energy distributors. The manufacturer is based in China, which is standard across the photovoltaic panel industry — the critical indicators are IEC certification and Tier 1 status, both of which this series holds.
What system size using DAS-DH108ND panels is needed for a typical single-family home?
For an average household consuming 3,500–4,500 kWh per year, a system of 8–12 DAS-DH108ND panels rated up to 460 Wp each is typically sufficient, yielding an installed capacity of 3.7–5.5 kWp. The compact module dimensions of 1800×1134 mm make it easier to fit more modules on a limited pitched-roof surface. The exact system sizing should always account for roof orientation, tilt angle, and local shading conditions.
