This directly improves the bankability of long-term installations and reduces the calculated degradation risk in DCF models. - **Low degradation rate: ~0.54%/year** - Thanks to the Dual Nano Absorber technology with active LID and LeTID mitigation, the manufacturer claims a degradation rate of approximately 0.54%/year, compared to the industry average for PERC cells, which is 0.7–0.8%/year. Over a 30-year lifespan, this difference accumulates to several additional percentage points of remaining power compared to competing modules. - **Double-sided bifacial glass construction** - Double glazing eliminates the risk of micro-cracks and moisture permeation, while bifacial modules allow for an additional 15-25% energy yield from reflected light (depending on the surface albedo). In ground-mounted and highly reflective roof installations, the effective power of the module exceeds the nominal STC value. - **Mechanical strength exceeding IEC standards** - The certified load capacity is 5400 Pa for snow and 6200 Pa for wind, which significantly exceeds the basic requirements of IEC 61215 (2400 Pa for wind). This makes the series suitable for installation in challenging climatic zones without the need to use additional reinforcement for the supporting structure. - **Efficiency of 20.9–21.29% at the level of top performers (PERC)** - The performance range is almost identical to that of direct competitors in the segment: Goldi Solar GS10-B144-TF (21.3%), IBC Solar 182M Half Cell (21.28%), and S-Energy SL65-72BGJ (21.3%). The series does not lag behind the leaders in the key conversion parameter, while also offering a longer warranty and a unique design. ## Cons - **PERC Technology – Decreasing Market Advantage** - The large-scale market is dynamically shifting towards N-type cells (TOPCon, HJT), which offer inherently lower LID (light-induced degradation) without additional processing, as well as better temperature coefficients. The DNA 144 series, based on PERC (Passivated Emitter and Rear Cell), may exhibit lower residual losses and limited attractiveness for project financing in the 2026-2028 timeframe, as N-type cell prices become more competitive. - **Not BNEF Tier 1 status** - Aptos Solar does not appear on the BNEF Tier 1 list (a ranking that requires independent bank financing for at least 6 projects exceeding 10 MW within 24 months). This could make it more difficult or increase the cost of project financing for large commercial and PV farm installations, as financial institutions typically require modules from Tier 1 manufacturers. - **A brief overview of the operational history of the manufacturer.** - Aptos Solar was founded in 2019 – the company has only about 6 years of experience in the market and lacks a documented, long-term financial history. The offered 30-year warranty is backed by a relatively new player, which is a standard risk in due diligence for projects with an investment horizon of over 20 years. ## About this series The DNA 144-Bifacial Dual Glass series redefines performance standards thanks to the patented **Dual Nano Absorber** technology, which allows for efficient energy generation even in extremely high ambient temperatures. The **glass-glass** design eliminates the risk of micro-cracks and corrosion, which, combined with bifacial cells, drastically increases the total energy yield per unit area by utilizing light reflected from the ground. These panels effectively solve the problem of light-induced degradation (LID and LeTID), ensuring power production stability over several decades. An advanced anti-reflective coating further supports photon absorption, making these modules some of the most efficient on the market. This solution is primarily dedicated to demanding **commercial installations and photovoltaic farms**, where maximizing the return on investment while reducing maintenance costs is key. What sets them apart from the competition is the unique half-cut cell architecture, which minimizes resistance losses and improves performance in partial shade conditions. Thanks to **exceptional mechanical resistance** to extreme wind and snow loads, this series performs in the toughest weather conditions, offering safety and reliability unattainable for standard monofacial modules. It is an investment in the highest **durability and maximum yield** from every installed kilowatt of power. ## Notable figures - At 21.1% efficiency, this panel is on par with typical \*\*PERC 500-550W\*\* modules - At 211.0 W/m² power density, roof space requirements are typical for \*\*PERC 500-550W\*\* panels - At -0.34%/°C, hot weather performance is typical for \*\*PERC 500-550W\*\* panels - At 32.3 kg (3.9 kg above \*\*PERC 500-550W\*\* median of 28.4 kg), requires checking roof load capacity - Bifaciality factor of 100% can add 5-15% extra yield with reflective mounting surface ## Questions ### What is the actual power output of the Aptos Solar DNA 144-Bifacial Dual Glass panels, and what does bifacial technology offer? The DNA-144-BF10-550W-DG model achieves a nominal peak power of 550 W under Standard Test Conditions. Thanks to bifacial cells, the rear side of the panel absorbs light reflected from the ground surface; with a 25% bifaciality factor, this enables effective power output of up to 688 W per module. In practice, the actual gain depends on ground albedo, tilt angle, and mounting height above the surface. ### What is the Dual Nano Absorber technology used in Aptos Solar DNA 144 panels, and does it genuinely improve performance in high-heat conditions? Dual Nano Absorber is a PERC cell architecture patented by Aptos Solar in which thin-film nanostructures absorb a greater number of photons and reduce efficiency losses at elevated temperatures. Standard panels typically lose approximately 0.30–0.45% of power for each degree Celsius above 25°C. The DNA technology mitigates this effect and sustains higher energy yield on hot summer days, which has a direct positive impact on annual energy production in commercial installations. ### What warranty covers the DNA 144-Bifacial Dual Glass series, and what does the manufacturer guarantee after 25 years? Aptos Solar provides a 30-year product warranty and a 30-year power output warranty. Under the warranty terms, panel power does not fall below 98% of the nominal value in the first year, after which it degrades by no more than 0.54% per year. After 30 years, the panel is guaranteed to produce at least 82.9% of its rated power. The warranty is issued by the manufacturer headquartered in the United States. ### Are Aptos Solar DNA 144-Bifacial Dual Glass panels suitable for utility-scale solar farms, and what mechanical loads can they withstand? Yes, the DNA 144-Bifacial Dual Glass series is designed primarily for commercial installations and utility-scale solar farms. The glass-glass construction withstands snow loads of up to 5,400 Pa and wind loads of up to 4,000 Pa, corresponding to extreme weather conditions. The large module dimensions and high unit power of 550 W reduce the number of panels required per megawatt, thereby lowering the costs of mounting structures and cabling as part of the overall BoS. ### Are the DNA 144-Bifacial Dual Glass panels resistant to LID and LeTID degradation, which affects older PERC cells? Yes, Aptos Solar declares effective mitigation of both Light-Induced Degradation (LID) and Light and elevated Temperature-Induced Degradation (LeTID), the latter being caused by the combined effect of illumination and elevated operating temperature. This is a significant advantage for PERC cells, which without adequate countermeasures can lose several percent of power during the early stages of operation. Stable power generation from the first days of operation translates directly into a better return on investment over the long-term service life of the system. ### How many Aptos DNA 144-Bifacial Dual Glass 550 W panels do I need for a 10 kW system for a business or warehouse? At a nominal power of 550 W, 19 panels are sufficient to achieve almost exactly 10.45 kWp. If the project requires strictly 10 kWp, 18 units (9.9 kWp) will suffice. The final number of modules also depends on cable losses, the inverter's MPPT input range, and the available roof or ground area. Given the large form factor of 550 W class modules, it is advisable to verify the load-bearing capacity and dimensions of the roof section in advance. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/DNA-144-BF10-550W-DG_Datasheet_Ref082724-1b3cb7f13fe2.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +3.9 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +3.7 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +3.7 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +3.6 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +3.5 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +3.4 pp | | [Aptos Solar DNA-144-BF10-540W-DG](https://comparepv.com/panel/aptos-solar-dna-144-bf10-540w-dg) | 540 W | Very close match | | [Aptos Solar DNA-144-BF10-550W-DG](https://comparepv.com/panel/aptos-solar-dna-144-bf10-550w-dg) | 550 W | Very close match | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +105 W, cooler, +4.1 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +100 W, cooler, +3.9 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +95 W, cooler, +3.7 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +90 W, cooler, +3.5 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +85 W, cooler, +3.3 pp | --- Source: https://comparepv.com/panel/aptos-solar-dna-144-bf10-545w-dg 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.
