Solid all-round for its segment
DAH DHN-54R18/DG(BW) panels revolutionize the market thanks to the patented Full Screen technology, which completely eliminates the traditional frame on the edges of the front glass. This solution effectively eliminates the problem of water and dust accumulation at the bottom of the module, which directly translates into higher energy yields by up to several percent annually. The use of advanced N-type TOPCon cells ensures excellent performance in low sunlight and minimal power degradation over time, guaranteeing long-term stability for every investment. The Bifacial Double Glass design with a double layer of glass significantly increases mechanical resistance to extreme weather events and allows for additional power generation from light reflected from the ground. This series is an ideal choice for prosumer installations and modern solar farms, where maximizing efficiency within a limited mounting area is key. A standout feature compared to the competition is the self-cleaning function, which drastically reduces the costs of operating and servicing the system. Thanks to the aesthetic finish and innovative frameless design, these modules combine modern design with uncompromising technology, offering users peace of mind and tangible savings through decades of safe use in harsh environmental conditions.

Signals from the data
Residential and commercial.
The series achieves up to 22.78% efficiency — more than 1.3 percentage points above the comparable Jinko Solar JS182MHC120 (21.48%) and nearly 1.9 percentage points above the Vikram SOMERA (20.91%). This translates into meaningfully higher energy yield per m² of roof area.
Complete elimination of the front-glass frame (DAH Solar global patent application) prevents water and debris accumulation at the module's lower edge. The self-cleaning effect reduces soiling losses — industry-estimated at 2–5% of annual yield — and lowers ongoing maintenance costs.
TOPCon technology delivers a lower light-induced degradation (LID) rate compared to P-type PERC cells used in older competing models. The manufacturer warrants >87.4% of nominal power output after 30 years of operation — an uncommon commitment in this segment.
The power warranty spans 30 years (87.4% after 30 years), whereas most comparable Tier-1 models (Jinko, Vikram) cap out at a 25-year threshold. The additional 5-year coverage directly reduces investment risk for commercial installations and utility-scale PV plants.
The glass-glass construction withstands 5,400 Pa snow load and 2,400 Pa wind load per the series datasheets. Additional generation from reflected irradiance (bifacial gain typically 5–15% depending on ground albedo) increases annual yield without expanding the mounting footprint.
DAH Solar has maintained BNEF Tier 1 status for consecutive quarters (confirmed Q1–Q4 2025), meeting the tightened ≥10 MW project criterion introduced in 2025. This status is a prerequisite for financing from most institutions involved in utility-scale PV projects.
The frameless design requires dedicated edge clamps with rubber adapters in place of standard aluminum mid/end clamps. DAH Solar supplies the adapters in the box; however, not all racking systems available on the Polish market are factory-ready for frameless modules, which may extend the design phase or require a change of mounting structure supplier.
- Efficiency of 22.5% matches the TOPCon 450-500W median
- Power density of 225.4 W/m² matches the TOPCon 450-500W median
- At -0.29%/°C, hot weather performance is typical for TOPCon 450-500W panels
- Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof
- In the top 28% for efficiency among all TOPCon panels
