Microinverters (one per panel)

No microinverter in the reference set lists this power class in its recommended module power range.

Voltage check against the microinverter datasheets — confirm the pairing on the manufacturer’s module compatibility list. Rows appear only when the panel’s power is inside the microinverter’s recommended module power range.

SolarEdge and other optimizer-based systems size strings by the optimizer rules — use the manufacturer’s designer. Reference inverters: most named in SoCal permits since Oct 2024.

Questions & answers

How efficient is the Canadian Solar CS6.2-66TB-605H?

Calculated from the panel area (2.7 m²): about 22.4% for the 605 W class. 605 W over 2.7 m² equals about 224 W per square meter.

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

PVWatts v8 with typical-year weather gives about 1,014 kWh per year per 605 W panel in Los Angeles and about 1,110 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 2–11 panels per string (Voc at 2 °C = 50.5 V, Vmp at 74 °C cell = 33.9 V). Final design must follow the inverter manual and NEC 690.7.

How big and heavy is it?

93.8 × 44.6 × 1.57 in (2,382 × 1,134 × 40 mm), 73.6 lb (33.4 kg).

Is it bifacial?

Yes, bifaciality 80%. Rear gain depends on mounting height and ground reflectance.

Has this panel been reliability-tested?

CS6.2-66TB-xxx was a PVEL Top Performer in 2025 (LID+LETID, PID, TC) — a closely related product name.
