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 CS6W-580TB-AG?

Calculated from the panel area (2.58 m²): about 22.5% for the 580 W class. 580 W over 2.58 m² equals about 225 W per square meter.

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

PVWatts v8 with typical-year weather gives about 972 kWh per year per 580 W panel in Los Angeles and about 1,064 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 2–10 panels per string (Voc at 2 °C = 55.2 V, Vmp at 74 °C cell = 35.9 V). Final design must follow the inverter manual and NEC 690.7.

How big and heavy is it?

89.7 × 44.6 × 1.57 in (2,278 × 1,134 × 40 mm), 69.7 lb (31.6 kg).

Is it bifacial?

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

Has this panel been reliability-tested?

This exact series is not in published PVEL Top Performer tables; Canadian Solar was named a Top Performer in 5 Scorecards (2020–2026).
