Questions & answers

How efficient is the Qcells Q.PEAK DUO BLK-G10+/AC 360?

The Qcells datasheet guarantees at least 20.1% module efficiency for the 360 W class (up to 20.3% for 365 W). 360 W over 1.66 m² equals about 217 W per square meter.

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

PVWatts v8 with typical-year weather gives about 603 kWh per year per 360 W panel in Los Angeles and about 661 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.34 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 17.6% below the STC rating.

What does the warranty cover?

25 years on the product and 25 years linear on performance: at least 98% of rated power in year 1, then no more than 0.5% per year — at least 86% after 25 years (manufacturer datasheet).

Has this panel been reliability-tested?

Q.PEAK DUO BLK-G10+ was a PVEL Top Performer in 2023 (LID+LETID, PID) — a closely related product name.

What fire rating does it have?

UL 61730 fire rating Type 2 per datasheet.
