Questions & answers

How efficient is the Canadian Solar CS6.2-48TM-445H?

The Canadian Solar datasheet guarantees at least 22.3% module efficiency for the 445 W class (up to 23% for 460 W). 445 W over 2 m² equals about 223 W per square meter.

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

PVWatts v8 with typical-year weather gives about 746 kWh per year per 445 W panel in Los Angeles and about 817 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.29 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 15% 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 3–15 panels per string (Voc at 2 °C = 37.6 V, Vmp at 74 °C cell = 25.4 V). Final design must follow the inverter manual and NEC 690.7.

What does the warranty cover?

25 years on the product (manufacturer datasheet).

How big and heavy is it?

69.4 × 44.6 × 1.38 in (1,762 × 1,134 × 35 mm), 48.1 lb (21.8 kg).

Has this panel been reliability-tested?

CS6.2-48TM-xxxH was a PVEL Top Performer in 2026 (HSS, LID+LETID, PID, UVID).

What fire rating does it have?

UL 61730 fire rating Class C per datasheet.
