Strong in heat, heavy for its output
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.

Aptos Solar offers a 30-year warranty on both the product and the power output – a rarity in the PERC segment, where most direct competitors (Goldi Solar GS10-B144-TF, IBC Solar 182M, S-Energy SL65-72BGJ) typically offer a standard 25-year warranty. This directly improves the bankability of long-term installations and reduces the calculated degradation risk in DCF models.
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 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.
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.
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.
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.
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.
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.
- 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
