Middle of its segment, modest efficiency
DAH Bifacial Double Glass Module N-Type series photovoltaic panels are a breakthrough solution that effectively eliminates one of the biggest problems of traditional installations - the accumulation of sediment and water on the module edges. Thanks to the use of unique, patented Full Screen technology, which features a completely frameless design on the front side, contaminants are naturally removed by rainfall. This approach drastically reduces the risk of harmful hot-spots and allows for significantly higher electricity production on an annual basis. The use of advanced N-type cells in TOPCon technology translates into higher efficiency in low light and exceptional resistance to light-induced degradation. Additionally, the bifacial double glass design enables active energy generation from both sides of the panel, which is particularly beneficial for systems mounted on bright surfaces with a high albedo coefficient. This series stands out from the competition with its excellent resistance to the PID effect and extreme weather conditions, such as strong winds or snow loads. It is an ideal choice for investors focusing on the highest reliability, fire safety, and maximizing profit per unit of area. These modules are perfect for both aesthetic home installations and large-scale commercial projects, ensuring peace of mind and the highest yields for decades.

Signals from the data
Commercial, utility-scale, cold-climate and hot-climate.
Tight roof space, roofs where every square metre has to count and weight-limited structures.

The frameless front-side design (DAH Solar patent) eliminates water and debris accumulation along panel edges. Natural rain self-cleaning reduces the risk of hot spots and production losses caused by soiling-induced partial shading.
N-type TOPCon cells exhibit significantly lower light-induced degradation (LID) than legacy PERC technology, along with superior performance at elevated temperatures and under diffuse low-irradiance conditions. This translates into a measurably higher annual energy yield under Polish climatic conditions compared to PERC-based modules.
The module harvests energy from both faces — the rear glass layer (replacing a conventional backsheet) delivers long-term durability and moisture resistance. On high-albedo surfaces (albedo >25%), a bifaciality factor of approximately 85% can contribute an additional 5–15% annual energy yield relative to monofacial modules.
DAH Solar provides a 30-year linear power output warranty, one of the longest warranty terms available in this segment. By comparison, many Tier-2 models offer only a 25-year power warranty. An extended warranty horizon is critical for project finance bankability and LCOE calculations on commercial-scale installations.
DAH Solar appears on the BNEF Tier 1 PV Module Manufacturers list across consecutive quarters in 2025 (Q1, Q3, Q4 2025), confirming bankability and enabling access to project financing without the additional credit enhancements typically required for lower-tier manufacturers.
The series reaches a maximum efficiency of 22.7%, while direct competitors achieve measurably higher values — Jinko Tiger Neo 66HL4M at 23.51% and LONGi Hi-MO X10 LR7-72HVD at 23.5% — a gap of approximately 0.8 percentage points. On roof installations with limited available area, this results in a lower peak power density per m².
The product warranty covering manufacturing defects and workmanship is only 15 years, whereas leading Tier-1 manufacturers — LONGi, Jinko, and Trina — standardly offer a 25-year product warranty in this segment. The shorter coverage period may be a material concern in long-term project financing or leasing arrangements.
- At 21.8% efficiency, this panel is 1.0pp below the TOPCon 600-650W median of 22.8%
- Power density of 218.2 W/m² is 9.5 W/m² below TOPCon 600-650W median (227.7 W/m²) - needs more roof space
- Temperature coefficient of -0.30%/°C matches the TOPCon 600-650W median
- At 34.3 kg, this panel is 1.6 kg heavier than the TOPCon 600-650W median (32.7 kg) - more demanding for installation crews
- 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces
