This translates into meaningfully higher energy yield per m² of roof area. - **Patented Full Screen technology** - 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. - **N-type TOPCon cells – low degradation** - 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. - **30-year linear power warranty** - 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. - **Bifacial double glass – mechanical robustness** - 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. - **Confirmed bankability – BNEF Tier 1** - 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. ## Cons - **Non-standard frameless mounting** - 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. ## About this series 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. ## Notable figures - 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 ## Questions ### What is the warranty on the DAH Solar DHN-54R18/DG(BW) panels? The DHN-54R18/DG(BW) series is covered by a 25-year product warranty against material and workmanship defects. In addition, the manufacturer provides a 30-year linear power output warranty — after 30 years of operation, the module retains at least 87.4% of its nominal power. This is one of the longest power output warranties available on the market, reflecting the manufacturer's confidence in the long-term durability of the system. ### What is the Full Screen technology in the DAH Solar DHN-54R18/DG(BW) panels, and does it genuinely increase energy yield? Full Screen is a patented DAH Solar design that completely eliminates the conventional aluminum frame along the edges of the front glass. As a result, rainwater and dust deposits do not accumulate in the lower frame profile of the module. In practice, this translates into higher energy yields — estimated at several percent per year compared to standard framed modules — while simultaneously reducing maintenance costs. ### Are the DAH Solar DHN-54R18/DG(BW) Bifacial Double Glass panels resistant to extreme weather conditions? Yes. The double-glass (Bifacial Double Glass) construction provides resistance to snow loads of up to 5,400 Pa and wind loads of up to 2,400 Pa. The absence of a plastic backsheet eliminates the risk of delamination and moisture ingress. With module dimensions of 1800×1134×30 mm and a weight of 24.4 kg, these modules are designed for long-term operation in harsh climatic conditions, including the variable snowfall and frost characteristic of the Polish climate. ### What is the maximum power output of the DAH Solar DHN-54R18/DG(BW) panel and what is its efficiency? The DHN-54R18/DG(BW) series was available in variants ranging from 450 to 465 Wp, with the top-tier version achieving 465 Wp. Module efficiency ranges from 22.05% to 22.78% — a level typical of the best N-type TOPCon cells on the market. The power temperature coefficient (-0.29%/°C) is more favorable than that of P-type PERC cells, meaning lower power losses on hot days. ### Do the DAH Solar DHN-54R18/DG(BW) panels generate additional current from the rear side of the module? Yes. Thanks to the bifacial design, the rear side of the panel generates energy from irradiance reflected off the ground or surrounding surfaces. The production gain typically ranges from 5–25%, depending on the type of surface beneath the installation (white gravel, light-colored membrane, grass) and the mounting angle. The bifacial gain is particularly pronounced in ground-mounted systems and on rooftops with light-colored coverings. ### Is the DAH Solar DHN-54R18/DG(BW) series still available for purchase? The DHN-54R18/DG(BW) series has been discontinued and is no longer actively offered by DAH Solar through standard distribution channels. Individual units may still be available from select PV wholesalers as existing stock. If you are planning a new installation, it is advisable to contact your distributor about the current successor model from the manufacturer's newer generation of N-type TOPCon Full Screen modules. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/en-dhn-54r18-dg-bw-450-465w-2a0493d68621.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +50 W, cooler, +2.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +35 W, lighter, +2.3 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +45 W, cooler, +2.2 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +30 W, lighter, +2.0 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +40 W, cooler, +2.0 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +40 W, lighter, +2.0 pp | | [DAH Solar DAS-DH108ND-440W](https://comparepv.com/panel/dah-solar-das-dh108nd-440w) | 440 W | -20 W, lighter, -0.9 pp | | [DAH Solar DAS-DH108ND-445W](https://comparepv.com/panel/dah-solar-das-dh108nd-445w) | 445 W | -15 W, lighter, -0.7 pp | | [DAH Solar DHN-54R18/DG-450W](https://comparepv.com/panel/dah-dhn-54r18-dg-450w) | 450 W | -10 W, -0.5 pp | | [DAH Solar DHN-54R18/DG-455W](https://comparepv.com/panel/dah-dhn-54r18-dg-455w) | 455 W | -0.2 pp | --- Source: https://comparepv.com/panel/dah-dhn-54r18-dg-bw-460w-1 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
