This technological advancement, compared to standard PERC modules without additional passivation, is confirmed by a patent held by the manufacturer. - **30-year performance guarantee with a curve** - The manufacturer guarantees ≥98% power output in the first year, ≥90.7% after 20 years, and ≥85.1% after 30 years, with a degradation rate of ≤0.54%/year. Most of the market only offers 25-year performance warranties, making this series a better option for projects with long-term financing horizons. - **High mechanical strength** - The modules can withstand wind loads of 6,200 Pa and snow loads of 5,400 Pa, exceeding the standard requirements of IEC 61215 (2,400/5,400 Pa). This is a key parameter for installations in Polish climatic conditions, which are characterized by heavy snowfall and strong winds. - **Favorable temperature coefficient** - Pmax = −0.36%/°C performs better than typical PERC modules (−0.38 to −0.40%/°C). At an operating temperature of 70°C, which is typical for Polish summer conditions, this translates to approximately 0.5–1.5% higher power output compared to the average PERC module of the same class. - **Half-cut 144-cell construction** - Dividing the cells into pairs reduces the current in each cell by 50%, which lowers resistive losses and increases resistance to partial shading. The 144-cell format optimizes the power-to-cost ratio for cabling in commercial and PV farm projects. ## Cons - **Performance lower than that of N-type peers** - The 19.75–20.21% range is significantly lower than all comparable products: KDM Kingdom Solar (22.5%), Lina Energy (22.37%), and Luxor Solar (22.86%) – the difference is 2.2–3.1 percentage points. For the same 440 W power output, the DNA 144 series occupies approximately 10–13% more roof space, which is a significant limitation in prosumer installations with limited space. - **P-type PERC vs. N-type TOPCon: A Comparison Among Peers** - All comparable technologies use N-type TOPCon, which exhibits a lower LID (Light-Induced Degradation) and better long-term thermal stability. PERC is a technology of an older generation, which may result in faster real degradation over a 25–30-year lifespan. - **Manufacturer outside the BNEF Tier 1 ranking** - Aptos Solar (founded in 2019) does not appear on the BNEF Tier 1 bankability list according to the BloombergNEF methodology as of March 2026. For commercial and PV farm projects, Tier 1 status is often a formal requirement of financing banks and insurance companies, which can limit the use of this series in large-scale investments. ## About this series The Aptos Solar DNA 144 photovoltaic panel series redefines performance standards thanks to the use of patented **Dual Nano Absorber (DNA)** technology, which allows for efficient energy generation even in difficult lighting conditions and at high ambient temperatures. The innovative approach to split-cell design significantly reduces losses resulting from internal resistance and minimizes the negative impact of partial shading on the operation of the entire string. These modules are characterized by **exceptional mechanical durability**, which, combined with advanced lamination, effectively protects the cells against micro-cracks and potential-induced degradation (PID). DNA 144 is a solution created for **demanding commercial projects** and solar farms, where the priority is to achieve the maximum power density ratio from the available surface. By using the 144-cell format, these panels optimize installation and cabling costs while offering **better performance in full sun** compared to traditional silicon modules. It is an option for investors seeking a balance between modern technology and robust construction, guaranteeing stable yields and **energy security for many years** of operation in the variable Polish climate. ## Notable figures - Module efficiency of 19.8% is 0.9pp below average for \*\*PERC 400-450W\*\* panels (median: 20.6%) - Power density of 197.6 W/m² is 8.6 W/m² below \*\*PERC 400-450W\*\* median (206.2 W/m²) - needs more roof space - Temperature coefficient of -0.35%/°C matches the \*\*PERC 400-450W\*\* median - Weight of 25.1 kg is 3.1 kg above \*\*PERC 400-450W\*\* median (22.0 kg) - verify structural support - In the top 89% for efficiency among all PERC panels ## Questions ### What is Dual Nano Absorber (DNA) technology in the Aptos Solar DNA 144 panels, and does it genuinely improve energy yields? DNA technology is a patented Aptos Solar solution that combines a selective emitter PERC architecture with thin-film nano-absorber layers. The result is enhanced photon absorption under diffuse light conditions, a lower temperature coefficient, and approximately 5% greater active cell area compared to standard PERC cells. In practice, this translates to higher energy yields on overcast days and reduced power losses during summer months when the module temperature on a heated rooftop can be significant. ### What warranty is provided for the Aptos Solar DNA 144 panels, and what exactly does it cover? The manufacturer provides a 30-year product warranty covering material and workmanship defects, as well as a 30-year linear power output warranty. In the first year, the panel retains at least 98% of its nominal power, and annual degradation does not exceed 0.54% — a figure considerably better than the industry-standard range of 0.7–0.8% per year. After 30 years, the module is warranted to produce at least 82.4% of its rated 440 Wp output. ### Are the Aptos Solar DNA 144 440W panels suitable for commercial installations and utility-scale PV farms in Poland? Yes, the DNA 144 series is designed primarily for large-scale commercial projects and utility-scale PV farms. The 144-cell half-cut format optimizes cabling and mounting costs when deploying a large number of modules. The modules withstand snow loads of up to 5,400 Pa and wind loads of up to 6,200 Pa, meeting the requirements of Polish climatic standards. The high power density allows more energy to be harvested from a limited ground or rooftop area. ### How do the Aptos Solar DNA 144 panels perform in summer under high-temperature conditions? PERC cells incorporating the DNA nano-absorber layer exhibit an improved temperature coefficient compared to standard monocrystalline modules. The thin-film absorber technology reduces power losses during heat events, which is particularly relevant in Polish conditions where module temperature can exceed 60°C. The manufacturer emphasizes that DNA 144 modules generate energy more efficiently than conventional monocrystalline silicon panels under extreme ambient temperatures. ### Are the Aptos Solar DNA 144 panels resistant to partial shading, for example from a chimney or antenna? Thanks to the split-cell architecture — 144 half-cut cells — the DNA 144 module is significantly more resilient to localized shading than conventional 60- or 72-cell panels. Splitting each cell in half reduces internal resistance and limits the formation of hot-spots. However, this does not completely eliminate losses under heavy shading; for installations with challenging roof geometries, it is worth considering power optimizers or microinverters. ### Who manufactures the Aptos Solar DNA 144 panels, and is the brand trustworthy? Aptos Solar Technology is a U.S.-headquartered company founded by engineers with backgrounds in the semiconductor industry. The DNA 144 series modules carry IEC and UL certifications, and the manufacturer's panel failure rate is below 0.01%. The company backs its modules with a 30-year product warranty as well as a 30-year linear power output warranty, demonstrating confidence in the long-term durability of its products. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/dna-144-mf26-440w-datasheet-ref-04-09-24-812558928b5f.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A480-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a480-mah54mw) | 480 W | +50 W, cooler, +4.4 pp | | [Gokin GK-5-54HG-480M](https://comparepv.com/panel/gokin-gk-5-54hg-480m) | 480 W | +50 W, cooler, +4.4 pp | | [Jinko Solar JKM480N-48QL6-DB-F2-EU](https://comparepv.com/panel/jinko-solar-jkm480n-48ql6-db-f2-eu) | 480 W | +50 W, cooler, +4.3 pp | | [Gamko New Energy GKA96N-PRO-480W](https://comparepv.com/panel/gamko-new-energy-gka96n-pro-480w) | 480 W | +50 W, cooler, +4.3 pp | | [Aptos Solar DNA-144-MF26-435W](https://comparepv.com/panel/aptos-solar-dna-144-mf26-435w) | 435 W | +0.2 pp | | [Aptos Solar DNA-144-BF26-440W](https://comparepv.com/panel/aptos-solar-dna-144-bf26-440w) | 440 W | +10 W, cooler, +0.5 pp | | [Aptos Solar DNA-144-MF26-440W](https://comparepv.com/panel/aptos-solar-dna-144-mf26-440w) | 440 W | +10 W, +0.5 pp | | [Aptos Solar DNA-144-MF26-445W](https://comparepv.com/panel/aptos-solar-dna-144-mf26-445w) | 445 W | +15 W, hotter, +0.2 pp | | [Aptos Solar DNA-144-BF26-445W](https://comparepv.com/panel/aptos-solar-dna-144-bf26-445w) | 445 W | +15 W, cooler, +0.7 pp | | [Aptos Solar DNA-144-MF26-450W](https://comparepv.com/panel/aptos-solar-dna-144-mf26-450w) | 450 W | +20 W, hotter, +0.5 pp | | [Aptos Solar DNA-144-BF26-450W](https://comparepv.com/panel/aptos-solar-dna-144-bf26-450w) | 450 W | +20 W, cooler, +0.9 pp | | [Gamko New Energy GKA120N-PRO-590W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-590w) | 590 W | +160 W, cooler, +4.1 pp | | [Gamko New Energy GKA120N-PRO-585W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-585w) | 585 W | +155 W, cooler, +3.9 pp | | [Bisol BGO 580](https://comparepv.com/panel/bisol-bgo-580) | 580 W | +150 W, cooler, +3.8 pp | | [Gamko New Energy GKA120N-PRO-580W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-580w) | 580 W | +150 W, cooler, +3.7 pp | --- Source: https://comparepv.com/panel/aptos-solar-dna-144-mf26-430w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
