Questions & answers

How efficient is the EMMVEE Photovoltaic Power E565HCMW144-T?

Calculated from the panel area (2.56 m²): about 22.1% for the 565 W class. 565 W over 2.56 m² equals about 221 W per square meter.

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

PVWatts v8 with typical-year weather gives about 947 kWh per year per 565 W panel in Los Angeles and about 1,037 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.289 %/°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 = 53.6 V, Vmp at 74 °C cell = 35.1 V). Final design must follow the inverter manual and NEC 690.7.

Does it work with APsystems (Alt Power System) DS3-L microinverters?

Voltage check against the APsystems (Alt Power System) datasheet: Voc when cold 53.6 V vs max input 60 V; Vmp when hot 35.1 V vs MPPT low 28 V; recommended module power 265–570 W. Confirm on the microinverter maker’s compatibility list.

Has this panel been reliability-tested?

This exact series is not in published PVEL Top Performer tables; EMMVEE Photovoltaic Power was named a Top Performer in 4 Scorecards (2023–2026).
