Strong in heat, no clear weak spot
The Aptos Solar DNA 120 series is designed to maximize energy yield in locations where standard modules experience the highest losses - in hot weather, under varying conditions, and on roofs with limited surface area. Its key advantage is the patented Dual Nano Absorber (DNA) technology, which ensures stable module operation and helps to more effectively utilize solar radiation in challenging temperature conditions. The use of split cell technology and 10 ultra-thin busbars reduces resistive losses and improves light collection, resulting in more predictable annual energy production. The series also includes bifacial solutions, which allow for better utilization of reflected light on ground-mounted, flat-roof, and carport installations. The entire range is complemented by a 30-year warranty, which is important for investors who prioritize safety and low long-term energy costs.
Ranking
Signals from the data
Residential, commercial, shaded-installations and hot-climate.
Top 1% of the PERC 350-400 W segment, against a median of -0.350. Ranked 1,280th in the whole database.
Top 13% of the PERC 350-400 W segment, against a median of 25 yrs.
The maximum efficiency of the module is 20.29%, while the best comparable product (Solitek SOLID Bifacial) achieves 19.57%, and Silfab Prime NTC – only 18.7%. The advantage of approximately 0.7% over the nearest competitor translates into a higher yield per square meter of roof area, which is particularly important when the installation area is limited.
Aptos Solar offers a 30-year warranty on both the product and the power output – a standard market practice for PERC panels (e.g., Silfab, JA Solar). The guaranteed power output after 30 years is ≥82.4% of the nominal power, with an annual degradation rate of ≤0.54% (after the first year, the degradation is ≤2%).
The Pmax temperature coefficient for the DNA-120 series is -0.35%/°C, which places the series in the upper range of the PERC class. For a typical summer day in Poland (module ~65°C), this corresponds to a loss of approximately 14% compared to ~17–18% for weaker PERC modules with a Tcoeff of -0.40%/°C.
The patented Dual Nano Absorber technology improves photon absorption at low temperatures and in diffuse light. Combined with 10 ultra-thin busbars (10BB) and split-cell solar cells, it reduces resistive losses and increases the module's resistance to partial shading compared to standard 4–6BB configurations.
DNA-120 MF2 panels are manufactured in the United States, which allows commercial projects to receive tax benefits under the Inflation Reduction Act (ITC/PTC bonus for domestically produced components). This is a significant advantage for projects that are exported to the North American market or are funded by funds with the requirement of "Made in USA".
Aptos Solar (founded in 2019) is not listed on the BloombergNEF Tier 1 list for photovoltaic modules (as of Q1 2026), which could make it difficult to secure financing for projects exceeding 1 MW and may increase the perceived risk for insurers and financial institutions in Europe.
PERC cells are more susceptible to LID (Light-Induced Degradation) and have a lower temperature coefficient compared to N-type TOPCon or HJT cells, which are increasingly available in a similar price range. In a 30-year warranty perspective, the real-world degradation of PERC cells may be higher than that of competing N-type models.
The company has been operating since 2019 (approximately 6 years), which is a significant factor to consider when assessing the credibility of a 30-year warranty. For comparison, Silfab (a similar company) has been operating since 1979. There is no documented history of handling warranty claims over a long period.
- Efficiency of 20.0% is 0.6pp above the PERC 0-400W median (19.4%)
- 200.4 W/m² power density - 6.0 W/m² more than PERC 0-400W median (194.4 W/m²), more power per roof area
- Temperature coefficient of -0.27%/°C vs median -0.36%/°C means ~4% less power loss at 65°C
- #12197 for efficiency, #1280 for temperature performance out of 14005 panels
