Questions & answers

How efficient is the Aptos Solar DNA-120-BF10 460?

The Aptos Solar datasheet guarantees at least 21.3% module efficiency for the 460 W class. 460 W over 2.16 m² equals about 213 W per square meter.

How much energy does one panel produce in Los Angeles or Palmdale?

PVWatts v8 with typical-year weather gives about 771 kWh per year per 460 W panel in Los Angeles and about 844 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.35 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 18.1% below the STC rating.

How many panels fit on one string?

With the Tesla 1538000-xx-y (max DC 600 V, MPPT from 60 V, datasheet) in Los Angeles the calculator gives 3–13 panels per string (Voc at 2 °C = 44.1 V, Vmp at 74 °C cell = 27.6 V). Final design must follow the inverter manual and NEC 690.7.

What does the warranty cover?

30 years on the product (manufacturer datasheet).

How big and heavy is it?

75.1 × 44.6 × 1.38 in (1,908 × 1,134 × 35 mm), 51 lb (23.1 kg).

Is it bifacial?

Yes. Rear gain depends on mounting height and ground reflectance.

What fire rating does it have?

UL 61730 fire rating Type 1 per datasheet.
