This translates to a significantly lower investment risk over the entire lifespan of the installation. - **Bifacial with patented DNA technology** - The dual-sided construction, featuring patented Dual Nano Absorber (DNA) technology, allows for the generation of an additional 10 to 25% of power, depending on the surface albedo. Ideal for ground-mounted installations on light surfaces (concrete, gravel, snow). - **Mechanical strength: 5400 Pa** - The panel is certified to withstand snow and wind loads up to 5400 Pa, which is twice the minimum requirements of IEC 61215 (2400 Pa). This is particularly important in areas with heavy snowfall or strong winds. - **Efficiency of up to 21.25% – among the top performers in the segment** - The series achieves a maximum efficiency of 21.25%, placing it among the top direct competitors (LEDVANCE M395~415: 21.25%; Sunova TS-BG54: 21.25%), with only a 0.03% difference compared to AE Solar AURORA. This result is excellent for a premium segment product with an identical configuration of 108 cells. - **Half-cut design + multi-busbar** - Dividing the cells reduces internal resistance and losses under partial shading, while the multi-busbar technology shortens current paths and reduces the risk of microcracks – resulting in more stable performance over the long term without a significant increase in module cost. ## Cons - **The series has been discontinued (2025)** - The production of the DNA 108-Bifacial series was completed in 2025. This means limited availability on the market, potential difficulties in replacing damaged modules, and the risk of a lack of ongoing service support within the 30-year warranty period. - **PERC Technology – Being Replaced by TOPCon** - PERC bifacial achieves a bifaciality ratio of approximately 70%, while TOPCon cells achieve 80–90%. The annual degradation rate for PERC is 0.5–0.7% compared to approximately 0.25% for TOPCon. As of 2024, TOPCon accounts for over 66% of global module production, making PERC a declining technology for new investments. - **UL Class C fire rating** - The module is certified for fire resistance only in Class C (UL 61730), not Class A. This could be a formal limitation in jurisdictions that require Class A for installation on sloped roofs or in dense urban areas – it is necessary to verify local regulations before purchasing. - **Young producer without Tier-1 BNEF status** - Aptos Solar Technology has been operating since 2019 and is not included in the BNEF Tier 1 list (threshold: >1.5 GW annual production). Its shorter track record and smaller scale compared to market leaders (JA Solar, Jinko, Trina) could limit the "bankability" of the project when seeking external financing. ## About this series The Aptos Solar DNA 108-Bifacial panel series is an advanced solution utilizing patented DNA technology, which allows for maximizing energy yields while maintaining exceptional mechanical durability.

The DNA 108-Bifacial series has been discontinued from regular production and is no longer available as a new product through authorized distributors. Remaining units may still be sourced from secondary market intermediaries or distributor warehouse stock; however, availability is limited. If you are planning a new installation, it is advisable to consider currently manufactured Aptos Solar series or comparable bifacial panels from other manufacturers that offer equivalent or superior specifications. ### What warranty terms apply to the Aptos Solar DNA 108-Bifacial panels? The DNA 108-Bifacial series is backed by a 30-year product warranty and a 30-year linear power output warranty. After 30 years of operation, the module retains at least 87.8% of its original rated power. This is among the most comprehensive warranty terms available in the photovoltaic panel market, providing strong assurance of return on investment even over an extended project lifetime. ### What does the bifacial dual-glass construction of the Aptos Solar DNA 108 series mean, and how much additional energy can be gained? Bifacial panels generate electricity from both the front and rear surfaces of the module by capturing light reflected from the ground or surrounding surfaces. In the DNA 108-Bifacial series, the manufacturer claims up to 25% additional energy yield compared to a conventional monofacial panel. The bifacial gain is greatest over high-albedo surfaces such as white gravel, light-colored roofing membranes, or snow cover, which is why these modules are particularly well-suited for ground-mounted installations. ### What is the maximum power output and module efficiency of the Aptos Solar DNA 108-Bifacial panels? The top-tier variant of the DNA 108-Bifacial series delivers a peak power output of 415 W at a module efficiency of 21.25%. The PERC cell technology with selective emitter, combined with a 10-busbar multi-busbar architecture, minimizes resistive losses and maximizes energy extraction from the available cell area. All parameters are measured under Standard Test Conditions (STC); in real-world installations, the bifacial yield raises effective energy production above the nameplate values. ### Can the Aptos Solar DNA 108-Bifacial panels withstand heavy snow loads and high wind pressure? Yes, the DNA 108-Bifacial series meets rigorous mechanical standards: it is rated for a snow and wind load of 5,400 Pa, which exceeds the typical market requirements of 2,400–4,000 Pa. The module frame and dual-glass construction are engineered for demanding alpine locations and high-precipitation climates, ensuring that the installation remains safe and fully operational throughout the entire warranty period. ### Are the DNA 108-Bifacial panels from Aptos Solar suitable for a pitched roof on a residential building? The DNA 108-Bifacial modules measure approximately 1,722 × 1,134 mm and have a weight typical of the premium class, making them compatible with standard racking systems for pitched-roof installations. The 108-cell half-cut cell format provides better partial-shading tolerance than conventional 60-cell full-cell configurations. It should be noted, however, that the bifacial gain on pitched roofs is lower than in ground-mounted systems, since the amount of light reflected from roofing materials is considerably less than that reflected from a high-albedo ground surface. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/DNA-108-BF10-415W_Datasheet_Ref121924-51ae1398a48c.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Luxor Solar LX-440M/182-108+GG](https://comparepv.com/panel/luxor-solar-lx-440m-182-108-gg) | 440 W | +40 W, cooler, +2.6 pp | | [Just Solar JST-EDMH-(445-465)W-TD (450W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-450w-class) | 450 W | +50 W, cooler, +2.6 pp | | [Q-SUN Solar QNN182-HG450-54](https://comparepv.com/panel/qn-solar-pv-limited-qnn182-hg450-54) | 450 W | +50 W, cooler, +2.6 pp | | [Huayao HY440-N108BDD](https://comparepv.com/panel/huayao-hy440-n108bdd) | 450 W | +50 W, cooler, +2.6 pp | | [BYD NLBK-27-450](https://comparepv.com/panel/byd-nlbk-27-450) | 450 W | +50 W, cooler, +2.6 pp | | [Renesola RS41-450NBG-E3](https://comparepv.com/panel/renesola-rs41-450nbg-e3) | 450 W | +50 W, cooler, +2.6 pp | | [Aptos Solar DNA-108-BF10-405W](https://comparepv.com/panel/aptos-solar-dna-108-bf10-405w) | 405 W | +0.3 pp | | [Aptos Solar DNA-108-MF10-410W](https://comparepv.com/panel/aptos-solar-dna-108-mf10-410w) | 410 W | +10 W, +0.5 pp | | [Aptos Solar DNA-108-MF10-415W](https://comparepv.com/panel/aptos-solar-dna-108-mf10-415w) | 415 W | +15 W, +0.8 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +110 W, cooler, +4.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +95 W, cooler, +4.3 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +105 W, cooler, +4.2 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +90 W, cooler, +4.0 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +100 W, cooler, +4.0 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +100 W, cooler, +4.0 pp | --- Source: https://comparepv.com/panel/aptos-solar-dna-108-bf10-400w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
