This provides investors with a significantly longer period of protection. - **Patent-protected Dual Nano Absorber technology** - The DNA (Dual Nano Absorber) technology applies passive layers to half-cut PERC cells with 9 connection ribbons, which reduces losses due to partial shading and improves performance at high temperatures. This patented solution – not available from any of the companies mentioned above. - **High mechanical strength** - The module can withstand a snow load of up to 5400 Pa and wind loads of up to 6200 Pa, which meets the requirements of IEC climate zones for Poland (including mountainous areas). The silver-colored aluminum frame provides long-term resistance to corrosion. - **Half-cut cells – lower resistance losses** - The split-cell (144 half-cell) design reduces the working current by half in each row, lowering I²R losses and improving efficiency compared to standard 72-cell full-cell modules. ## Cons - **The product line has been discontinued.** - The DNA 144 Silver Frame is officially discontinued (launched in 2020, production has been confirmed to end). Availability of replacement modules for expanding the installation is limited, and enforcing the 30-year warranty offered by the 2019-founded manufacturer carries a real risk of lacking ongoing service support. - **PERC's efficiency is approximately 3 percentage points lower than that of its peers.** - The maximum efficiency of the series is 20.21%, while comparable models achieve 22.5% (Suntech Ultra V Pro mini) and 23.04% (SunKean/Sunket SKT430–450M10-108D5) at the same 450 Wp power. This means that to achieve 1 kWp, an Aptos installation requires approximately 12–14% more roof space. - **PERC technology – previous generation** - PER (Passivated Emitter and Rear Cell) solar cells are being replaced by TOPCon (Tunnel Oxide Passivated Contact) and HJT (Heterojunction with Intrinsic Thin-layer) technologies, which offer lower LID/LeTID degradation rates and better performance at high temperatures. Even PER cells of the same power rating (450 Wp) are now using newer generation solar cells, which, over a 30-year lifespan, results in a significantly lower cumulative energy yield. - **A brief overview of the market for the manufacturer** - Aptos Solar was founded in 2019, and this particular product line was launched in 2020 and quickly withdrawn from the market. The lack of a long-term track record (unlike Suntech, which has been on the market since 2001) makes it difficult to assess the true durability of the modules and the credibility of the long-term warranty. ## About this series Aptos Solar DNA 144 Silver Frame solar panels utilize patented DNA technology, which eliminates energy losses at the cell level and significantly increases system efficiency in challenging lighting conditions. Thanks to the use of split-cell construction and advanced busbars, these modules exhibit exceptional resistance to high temperatures, which directly translates into stable energy yield even in full sun. Choosing this series is primarily about **maximizing efficiency from limited roof space** and the assurance of a secure, long-term investment. The solid, silver frame provides not only an aesthetic appearance but also **extreme mechanical strength** against snow and wind loads, making them an ideal solution for demanding Polish climatic conditions. The DNA 144 series effectively addresses the problem of premature module degradation through technology that prevents the formation of micro-cracks. It is a product dedicated to conscious prosumers and business investors seeking **above-average reliability confirmed by rigorous quality tests**. Unlike standard solutions, Aptos Solar offers a **patented Dual Nano-cells structure** that optimizes current flow and minimizes the impact of spot shading. This is a solution for those who prioritize the **highest standard of fire safety** and American engineering that goes beyond market standards. ## Notable figures - Module efficiency of 20.0% is 0.6pp below average for \*\*PERC 400-450W\*\* panels (median: 20.6%) - At 204.4 W/m² power density, roof space requirements are typical for \*\*PERC 400-450W\*\* panels - -0.38%/°C temperature coefficient - 0.03pp worse than \*\*PERC 400-450W\*\* median (-0.35%/°C), expect higher hot weather losses - At 24.1 kg (2.1 kg above \*\*PERC 400-450W\*\* median of 22.0 kg), requires checking roof load capacity - In the top 88% for efficiency among all PERC panels ## Questions ### Are the Aptos Solar DNA 144 Silver Frame panels still available for purchase? The DNA 144 Silver Frame series has been discontinued by Aptos Solar and is no longer actively manufactured. Individual units may still remain as residual stock with Polish distributors; however, these panels should not be relied upon for future system expansion. If module compatibility and long-term availability are priorities, we recommend evaluating Aptos Solar's current lineup or an alternative manufacturer. ### What warranty coverage applies to the Aptos Solar DNA 144 Silver Frame panels? The manufacturer provided a 30-year product warranty covering material and workmanship defects, along with a 30-year power output warranty. Under the power warranty terms, the module was guaranteed to retain at least 98% of its nominal rated power in the first year, followed by a maximum annual degradation of 0.54% over the remaining 29 years. This represents one of the most comprehensive warranty standards available in the market. ### What is the Dual Nano-cells technology used in Aptos Solar DNA 144 panels and what are its benefits? Dual Nano-cells is a proprietary Aptos Solar technology that applies ultra-thin passivation layers to half-cut PERC cells in a 144-cell architecture. The result is reduced resistive losses, improved high-temperature tolerance, and minimized impact of partial shading on overall module output. In practice, this translates into higher real-world energy yield compared to standard PERC modules. ### Are the Aptos Solar DNA 144 Silver Frame panels suitable for Polish winter conditions? Yes, the silver anodized aluminum frame of the DNA 144 Silver Frame modules is engineered to withstand significant mechanical loads. The panels are rated for a snow load of up to 5400 Pa and a wind load of up to 6200 Pa, meeting Polish building code requirements for rooftops in high-snowfall zones. The split-cell architecture further reduces the risk of micro-crack formation caused by thermal cycling under fluctuating temperatures. ### What is the power output of the Aptos Solar DNA 144 Silver Frame panel, and is it sufficient for a single-family home? The module's peak power output is 450 Wp under Standard Test Conditions (STC). For a typical single-family home consuming 4,000–5,000 kWh per year, 8 to 12 panels of this rating are generally sufficient, corresponding to a system size of 3.6 to 5.4 kWp. The high power density of the DNA 144 series is particularly advantageous when available roof space is limited. ### Is the Aptos Solar DNA 144 Silver Frame panel bifacial? No, the Silver Frame variant of the DNA 144 series is a monofacial module that generates electricity solely from the front side of the cells. Aptos Solar offers a separate bifacial version designated with the BF suffix, intended for ground-mounted installations or rooftops with a light-colored membrane where albedo reflection from the surface is achievable. For typical rooftop installations on residential homes in Poland, the monofacial version is entirely adequate. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/dna-144-silver-frame-450w-datasheet-ref-04-09-2024-45e155ddea01.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +50 W, cooler, +4.8 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +45 W, cooler, +4.5 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +45 W, cooler, +4.5 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | Cooler, lighter, +4.3 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +40 W, cooler, +4.3 pp | | [Longi Solar LR7-54HJD-495M](https://comparepv.com/panel/longi-lr7-54hjd-495m) | 495 W | +50 W, cooler, +4.3 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +40 W, cooler, +4.3 pp | | [Aptos Solar DNA-144-MF26-430W](https://comparepv.com/panel/aptos-solar-dna-144-mf26-430w) | 430 W | -15 W, cooler, -0.2 pp | | [Aptos Solar DNA-144-MF26-435W](https://comparepv.com/panel/aptos-solar-dna-144-mf26-435w) | 435 W | -10 W, cooler, heavier | | [Aptos Solar DNA-144-BF26-440W](https://comparepv.com/panel/aptos-solar-dna-144-bf26-440w) | 440 W | Cooler, +0.3 pp | | [Aptos Solar DNA-144-MF26-440W](https://comparepv.com/panel/aptos-solar-dna-144-mf26-440w) | 440 W | Cooler, heavier, +0.2 pp | | [Aptos Solar DNA-144-BF26-445W](https://comparepv.com/panel/aptos-solar-dna-144-bf26-445w) | 445 W | Cooler, +0.5 pp | | [Aptos Solar DNA-144-MF26-450W](https://comparepv.com/panel/aptos-solar-dna-144-mf26-450w) | 450 W | +0.2 pp | | [Aptos Solar DNA-144-BF26-450W](https://comparepv.com/panel/aptos-solar-dna-144-bf26-450w) | 450 W | Cooler, +0.7 pp | | [Gamko New Energy GKA120N-PRO-590W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-590w) | 590 W | +145 W, cooler, +3.8 pp | | [Gamko New Energy GKA120N-PRO-585W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-585w) | 585 W | +140 W, cooler, +3.6 pp | --- Source: https://comparepv.com/panel/aptos-solar-dna-144-mf26-445w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
