Warranty pick, no clear weak spot
The Aptos Solar DNA 120-Bifacial solar panel series redefines performance standards through the use of patented Dual Nano Absorber technology, which minimizes energy losses and significantly increases photon absorption. A key differentiator of these modules is their bifacial design, allowing for the generation of additional yield from reflected radiation, which in optimal conditions increases system efficiency by up to 30 percent. These panels effectively solve the problem of limited mounting space and unfavorable shading thanks to advanced split-cell architecture with ten thin busbars. Designed for harsh climatic conditions, the DNA 120-Bifacial series is engineered to offer extreme mechanical resistance to wind and snow loads, significantly exceeding market standards. It is a solution dedicated to conscious investors seeking maximum bifacial performance and an elegant finish that blends perfectly with modern architecture. What sets them apart from the competition is exceptional operating stability at high temperatures and a 30-year linear power output warranty, ensuring investment security for decades. By choosing this series, users receive a product that combines Silicon Valley innovation with uncompromising durability, ideal for both demanding residential installations and extensive commercial projects focused on long-term reliability and a fast return on investment.

Aptos Solar offers both a 30-year product warranty and a 30-year power warranty, with a maximum annual degradation of 0.54%, ensuring a minimum of 82.4% of the nominal power after 30 years. Comparable series from Risen RSM96-11 and SunKean SKT440~460M12-96D4 standardly offer a 25-year power warranty – Aptos extends this period by 5 years.
The Dual Nano Absorber technology uses 10 ultra-thin collecting strips instead of the standard 3-5, eliminates corner clipping of solar cell elements (approximately +5% active surface area), and adds a layer of negatively charged atoms that enhance photon capture. This results in lower resistive losses and better shading tolerance compared to a standard PERC cell without this modification.
The double-sided design allows for the generation of additional energy from reflected radiation from the ground. According to the manufacturer's data, the rear side of the panel, with an albedo of 25%, generates 550-563 W from a 440 W module, which corresponds to a gain of 25-28%. Under mid-European conditions (snow, bright surface), the real annual gain ranges from 5-15%.
Aptos Solar subjects its modules to testing that is three times more rigorous than IEC standards (verified by an independent laboratory, certificate from 2020). This distinguishes the brand from typical tier-2 manufacturers and justifies the declared mechanical resistance to extreme wind and snow loads.
The most efficient variant of the series achieves 21.26%, while comparable models from Risen and SunKean (RSM96-11-440-460BNDG and SKT440~460M12-96D4) achieve 23.00% and 23.02% respectively – this represents a difference of approximately 1.8 percentage points. With a limited roof area (e.g., 30 m²), this translates to a significantly smaller installed power within the same footprint.
PERC (Passivated Emitter and Rear Cell) solar cells exhibit a higher light-induced degradation (LID) rate and a lower temperature coefficient of power compared to N-type TOPCon cells of the same power class available from Risen and SunKean. Independent studies indicate that N-type panels generate 1.5–2.5% more energy per year than PERC panels under the same Standard Test Conditions (STC).
Aptos Solar (founded in 2019) is not listed in Bloomberg NEF's Tier-1 category – it is classified as Tier-2. This could make it more difficult to secure project financing (bankability) for commercial installations exceeding 50 kWp and could also reduce the residual value of the system upon property transfer.
- At 21.0% efficiency, this panel is on par with typical PERC 450-500W modules
- At 210.3 W/m² power density, roof space requirements are typical for PERC 450-500W panels
- Temperature coefficient of -0.35%/°C matches the PERC 450-500W median
- 22.8 kg weight - 1.7 kg lighter than PERC 450-500W median (24.5 kg), reducing installation effort
- Ranked #9671 out of 14005 panels for efficiency in the database
