Comparable series from Risen RSM96-11 and SunKean SKT440~460M12-96D4 standardly offer a 25-year power warranty – Aptos extends this period by 5 years. - **Patented DNA technology with 10 bases** - The Dual Nano Absorber technology uses 10 ultra-thin collecting strips instead of the standard 3-5, eliminates corner clipping of solar cell elements (approximately +5% active surface area), and adds a layer of negatively charged atoms that enhance photon capture. This results in lower resistive losses and better shading tolerance compared to a standard PERC cell without this modification. - **Dual-sided operation with potential gains of up to 30%** - The double-sided design allows for the generation of additional energy from reflected radiation from the ground. According to the manufacturer's data, the rear side of the panel, with an albedo of 25%, generates 550-563 W from a 440 W module, which corresponds to a gain of 25-28%. Under mid-European conditions (snow, bright surface), the real annual gain ranges from 5-15%. - **Testing performed 3 times more rigorously than IEC standards** - Aptos Solar subjects its modules to testing that is three times more rigorous than IEC standards (verified by an independent laboratory, certificate from 2020). This distinguishes the brand from typical tier-2 manufacturers and justifies the declared mechanical resistance to extreme wind and snow loads. ## Cons - **Efficiency of up to 21.26% compared to 23% among competitors** - The most efficient variant of the series achieves 21.26%, while comparable models from Risen and SunKean (RSM96-11-440-460BNDG and SKT440~460M12-96D4) achieve 23.00% and 23.02% respectively – this represents a difference of approximately 1.8 percentage points. With a limited roof area (e.g., 30 m²), this translates to a significantly smaller installed power within the same footprint. - **PERC technology instead of N-type** - PERC (Passivated Emitter and Rear Cell) solar cells exhibit a higher light-induced degradation (LID) rate and a lower temperature coefficient of power compared to N-type TOPCon cells of the same power class available from Risen and SunKean. Independent studies indicate that N-type panels generate 1.5–2.5% more energy per year than PERC panels under the same Standard Test Conditions (STC). - **No Tier-1 BNEF status** - Aptos Solar (founded in 2019) is not listed in Bloomberg NEF's Tier-1 category – it is classified as Tier-2. This could make it more difficult to secure project financing (bankability) for commercial installations exceeding 50 kWp and could also reduce the residual value of the system upon property transfer. ## About this series The Aptos Solar DNA 120-Bifacial solar panel series redefines performance standards through the use of **patented Dual Nano Absorber technology**, which minimizes energy losses and significantly increases photon absorption.

The DNA 120-Bifacial series is backed by a dual 30-year warranty covering both the product (physical integrity of the module) and linear power output. The manufacturer, Aptos Solar Technology, headquartered in the United States, guarantees that the module will maintain the required nominal power threshold throughout three full decades of operation. This is one of the longest product warranties currently available in the photovoltaic module market, providing investors with genuine long-term financial security. ### How does the Aptos Solar DNA 120-Bifacial bifacial panel differ from a conventional monofacial module? The DNA 120-Bifacial series generates electricity from both sides of the module simultaneously. The rear surface captures irradiance reflected from the ground, rooftop surface, or surrounding environment, which under optimal conditions can increase energy yield by up to 30% compared to a conventional monofacial panel with a nominal power rating of 460 W. The bifacial gain is most pronounced over high-albedo surfaces such as white roofing membranes, light-colored gravel, or snow. ### What are the dimensions and weight of the Aptos Solar DNA-120-BF10-460W module, and is it compatible with standard racking systems? The DNA-120-BF10-460W module measures 1908 x 1134 x 35 mm and weighs approximately 22.8 kg. This form factor is compatible with standard aluminum rail mounting systems widely available on the market. The half-cut cell architecture featuring ten narrow busbars reduces the risk of microcracks during transport and installation. The module is rated for system voltages up to 1500 V DC, which simplifies the design of larger utility-scale installations. ### Will the Aptos Solar DNA 120-Bifacial panels perform reliably in harsh winter conditions — heavy snow loads and prolonged overcast skies? Yes. The modules are rated for a mechanical load of 5,400 Pa on both the front and rear surfaces, which accommodates extreme snow loads and high wind pressures. The SE-PERC cell technology exhibits strong sensitivity to diffuse irradiance, which is characteristic of overcast sky conditions. Furthermore, the module encapsulation is resistant to potential-induced degradation (PID), salt, acids, and ammonia, ensuring stable year-round performance. ### What is the Dual Nano Absorber technology used in the Aptos Solar DNA 120-Bifacial series, and does it genuinely improve performance? Dual Nano Absorber (DNA) is Aptos Solar's proprietary technology that modifies the surface of the PERC cell at the nanometer scale. The nanostructured absorber layer reduces light reflection and increases the optical path length of photons within the cell, resulting in a module efficiency of up to 21.26%. This translates to higher energy yield from the same roof area compared to standard PERC panels that do not incorporate this technology. ### Is the Aptos Solar DNA 120-Bifacial series suitable for large commercial installations, or is it intended only for residential use? The DNA 120-Bifacial series is engineered for both residential prosumer installations and large-scale commercial projects. Support for a 1500 V DC system voltage enables longer string configurations, reducing balance-of-system (BoS) costs — including cabling and inverter count — in utility-scale deployments. The module holds Miami-Dade certification, confirming its resistance to extreme weather events, which is a key requirement for investors demanding the highest durability standards. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/dna-120-bf10-460w-datasheet-wref-071625-2-cd86974447b3.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +40 W, cooler, +3.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +50 W, cooler, +3.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +35 W, cooler, +3.5 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +45 W, cooler, +3.5 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +45 W, cooler, +3.5 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +45 W, cooler, +3.5 pp | | [Aptos Solar DNA-120-BF10-445W](https://comparepv.com/panel/aptos-solar-dna-120-bf10-445w) | 445 W | -10 W, -0.5 pp | | [Aptos Solar DNA-120-BF10-450W](https://comparepv.com/panel/aptos-solar-dna-120-bf10-450w) | 450 W | -0.2 pp | | [Aptos Solar DNA-120-MF10-460W](https://comparepv.com/panel/aptos-solar-dna-120-mf10-460w) | 460 W | Heavier, +0.2 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +105 W, cooler, +3.8 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +100 W, cooler, +3.6 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +95 W, cooler, +3.4 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +85 W, cooler, +3.4 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +85 W, cooler, +3.4 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | +90 W, cooler, +3.2 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | +90 W, cooler, +3.2 pp | --- Source: https://comparepv.com/panel/aptos-solar-dna-120-bf10-455w Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
