Which Aptos Solar Residential Panel Needs Less Roof for 10 kW, the 440W or the 460W?

Published September 23, 2026 · By the SolarPanelX editors · Prices and specs as of that date, from the pages under Sources

Summary

The lower-wattage 440 W class does. At 10,120 W each (23 of the 440 W modules or 22 of the 460 W modules), the DNA-108 MFN10 array covers about 44.9 m² and the DNA-120 MF10 array about 47.6 m². The 460 W module is 186 mm longer, uses SE-PERC cells, and tops out at 21.26% efficiency.

Three datasheets dated August 2026

Aptos labels each datasheet on its download page as RESIDENTIAL or COMMERCIAL. Here are the two residential models next to the commercial 595 W class.

Model	Label	Cells	Power bins	Dimensions	Weight	Top-bin efficiency	Top-bin Voc / Isc
DNA-108 MFN10	RESIDENTIAL	N-type	440, 445, 450 W	1,722 × 1,134 × 35 mm	21 kg	23.04%	39.29 V / 13.89 A
DNA-120 MF10	RESIDENTIAL / COMMERCIAL	SE-PERC	450, 455, 460 W	1,908 × 1,134 × 35 mm	23.1 kg	21.26%	41.70 V / 14.00 A
DNA-144 BFN10-DG	COMMERCIAL	N-type, dual glass	590, 595, 600 W	2,278 × 1,134 × 35 mm	32.0 kg	23.23%	52.73 V / 14.00 A

The two N-type models list a power temperature coefficient of -0.29% per °C, and the DNA-120 MF10 lists -0.353% per °C. At a cell temperature of 50°C, 25 degrees above the rating condition, that works out to losses of about 7.3% and 8.8%.

The 460 W array is also heavier: 483 kg for 23 of the 440 W modules against about 508 kg for 22 of the 460 W modules.

The warranty years differ from page to page

Where it appears	Product warranty	Power warranty
Home page	25 years	30 years
Company and warranty pages	30 years	30 years
Each datasheet	30 years	30 years

The limited warranty effective April 1, 2023 gives a 30-year product term. It allows 2% degradation in the first year and 0.54% a year from year 2 through year 30, ending at 82.9% of rated power. It does not name the product series it covers.

The company page says Aptos is headquartered in San Antonio, Texas, and that its products are made in factories in multiple countries, without naming them. The datasheets describe Aptos as a "100% American Owned Company."
