Questions & answers

How efficient is the Qcells Q.TRON BLK M-G2+ 430?

The Qcells datasheet guarantees at least 22% module efficiency for the 430 W class (up to 22.5% for 440 W). 430 W over 1.95 m² equals about 220 W per square meter.

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

PVWatts v8 with typical-year weather gives about 721 kWh per year per 430 W panel in Los Angeles and about 789 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.30 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 15.5% 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 3–14 panels per string (Voc at 2 °C = 41.5 V, Vmp at 74 °C cell = 27.5 V). Final design must follow the inverter manual and NEC 690.7.

What does the warranty cover?

25 years on the product and 25 years linear on performance: at least 98.5% of rated power in year 1, then no more than 0.33% per year — at least 90.58% after 25 years (manufacturer datasheet).

How big and heavy is it?

67.8 × 44.6 × 1.18 in (1,722 × 1,133 × 30 mm), 46.7 lb (21.2 kg).

Has this panel been reliability-tested?

This exact series is not in published PVEL Top Performer tables; Qcells was named a Top Performer in 11 Scorecards (2016–2026). RETC named Qcells Overall Highest Achiever in 2023, 2026.

What fire rating does it have?

UL 61730 fire rating Type 2 per datasheet.
