In typical Polish summer conditions (where panels reach temperatures of 60-70°C), the difference of 0.03-0.04%/°C translates into a real increase of 1-2% in daily energy yield compared to the average PERC module. - **Tensile strength of 5400 Pa (snow and wind)** - The modules can withstand both front and rear loads up to 5400 Pa, which is more than twice the minimum specified in IEC 61215 (2400/2400 Pa). This is a significant advantage for Polish rooftop installations that are exposed to heavy, wet snow and strong winds in mountainous and coastal regions. - **DNA Technology – 10 multi-busbar system** - The patented Dual Nano Armor construction, featuring 10 ultra-thin busbars, reduces mechanical stress within the cells, thereby minimizing the risk of micro-cracks. The additional active surface area (approximately 5% more than in standard cuts) improves performance without increasing the module's size. - **Half-cut cells + 6-class salt resistance** - The use of half-cut cells reduces the working current by half (lower resistive losses) and limits the impact of partial shading on the entire string. The achieved level of 6 salt spray resistance (according to IEC 61701) enables installation in marine and industrial environments. - **30-year power guarantee, degradation rate of 0.54% per year** - The manufacturer guarantees a minimum 82.4% of the nominal power output after 30 years, with an annual decrease of ≤0.54% (after the first year). A comparable product from Risen, the RSM96-11-440-460BNDG, also offers a 30-year lifespan, but the DNA-120 series remains competitive in this regard as a monolithic PERC with extended protection. ## Cons - **Performance is approximately 1.8 percentage points lower than that of competitor's TOPCon devices.** - The best efficiency achieved in this series is 21.26%, while the Risen RSM96-11-440-460BNDG (n-type TOPCon, with the same power range) achieves 23%, and the SunKean SKT440~460M12-96D4 – 23.02%. A difference of approximately 1.8% indicates the need to install approximately 8-9% more module area to achieve the same peak power, which could be a limitation in projects with limited roof space. - **Tier 2 manufacturer, market history since 2019** - Aptos Solar (founded in 2019, based in the USA) is not listed on the BNEF Tier 1 Q1 2026 list. This essentially means that it would face difficulties in obtaining bank financing for large commercial installations, where lenders typically require Tier 1 status. A comparable, established company is Risen Energy, which has a long-standing presence in global markets. - **30-year product warranty as a paid option** - The standard factory warranty covers the product for 15 years and the power output for 25 years. Achieving a 30-year product warranty requires purchasing an optional upgrade package. Investors who do not purchase this package receive a shorter product warranty than the marketing materials suggest, which should be verified before making a purchase. ## About this series The Aptos Solar DNA-120-Monofacial panel series is an advanced solution designed to maximize energy yields while maintaining extreme mechanical resistance for every module.

DNA (Dual Nano Armor) is a proprietary Aptos Solar technology combining advanced PERC cells with thin nano-absorptive layers and 10 ultra-thin busbars. The result is greater heat tolerance, lower resistive losses, and approximately 5% more active cell area compared to standard modules. In practice, this translates into higher efficiency (up to 21.26%) and more stable output during summer heat. ### What warranty does the Aptos Solar DNA-120-Monofacial series carry? The DNA-120-Monofacial series is covered by a 30-year product warranty (materials and workmanship) and a 30-year power output warranty. The manufacturer guarantees retention of at least 98% of rated power after the first year of operation, followed by an annual degradation rate of no more than 0.54%. After 30 years, the panel should still produce at least 82.34% of its nominal 460 W power output. ### Do the Aptos Solar DNA-120-Monofacial 460W panels handle partial shading well on pitched roofs? Yes. The use of half-cut cells — each cell being half the standard size — divides the module into two independent electrical sections. As a result, shading of even half the panel by a chimney, dormer, or antenna does not cause severe output losses across the entire module. This is a significant advantage for typical Polish gabled roofs with multiple architectural obstructions. ### How do the DNA-120-Monofacial panels withstand Polish winters — heavy snow loads and strong winds? The DNA-120-Monofacial series has passed load tests three times more stringent than required by the IEC standard. The modules withstand snow loads up to 5,400 Pa and wind loads up to 6,200 Pa. For comparison, typical market requirements are usually 2,400 Pa. The reinforced aluminum frame and tempered front glass make the panels well suited to Poland's variable climate, including heavy snowfall in mountain and sub-mountain locations. ### How much power does the Aptos Solar DNA-120-Monofacial panel lose at high summer temperatures? The power temperature coefficient is -0.35% per degree Celsius above 25°C (STC conditions). This is among the better results in the PERC module class — many competing panels achieve -0.38% to -0.40%/°C. In practice, on a hot day with a cell temperature of around 65°C, the panel loses approximately 14% of its power output, compared to 17–18% for thermally inferior modules. ### Are the Aptos Solar DNA-120-Monofacial panels suitable for both residential and commercial installations? Yes. The module dimensions of 1908 × 1134 mm and a weight of approximately 24 kg fall within the standard for residential installations, while the 460 W output and 1500 V system voltage make them an efficient choice for larger utility-scale farms and commercial facilities. The manufacturer — Aptos Solar, headquartered in the USA — offers purchase in individual pallets (31 units) and bulk containers (744 units), making it straightforward to scale any project. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/DNA-120-MF10-460W_Datasheet_Ref121924-81965aa158f1.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +45 W, cooler, +4.0 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +40 W, cooler, +3.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +50 W, cooler, +3.7 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +50 W, cooler, +3.7 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +50 W, cooler, +3.7 pp | | [GCL GCL-NR10R/54BGDF](https://comparepv.com/panel/gcl-gcl-nr10r-54bgdf) | 500 W | +50 W, cooler, +3.7 pp | | [Aptos Solar DNA-120-BF10-445W](https://comparepv.com/panel/aptos-solar-dna-120-bf10-445w) | 445 W | Lighter, -0.2 pp | | [Aptos Solar DNA-120-MF10-455W](https://comparepv.com/panel/aptos-solar-dna-120-mf10-455w) | 455 W | +0.2 pp | | [Aptos Solar DNA-120-MF10-460W](https://comparepv.com/panel/aptos-solar-dna-120-mf10-460w) | 460 W | +10 W, +0.5 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +110 W, cooler, +4.0 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +105 W, cooler, +3.8 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +100 W, cooler, +3.6 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +90 W, cooler, +3.6 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +90 W, cooler, +3.6 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | +95 W, cooler, +3.5 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | +95 W, cooler, +3.4 pp | --- Source: https://comparepv.com/panel/aptos-solar-dna-120-mf10-450w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
