Questions & answers

How efficient is the Mission Solar Energy MSE380SX5R?

The Mission Solar Energy datasheet guarantees at least 19.1% module efficiency for the 380 W class (up to 19.3% for 385 W). 380 W over 1.99 m² equals about 191 W per square meter.

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

PVWatts v8 with typical-year weather gives about 637 kWh per year per 380 W panel in Los Angeles and about 697 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.36 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 18.7% 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 3–12 panels per string (Voc at 2 °C = 47.5 V, Vmp at 74 °C cell = 29.5 V). Final design must follow the inverter manual and NEC 690.7.

Does it work with Enphase IQ8PLUS-72-2-US microinverters?

Voltage check against the Enphase datasheet: Voc when cold 47.5 V vs max input 60 V; Vmp when hot 29.5 V vs MPPT low 29 V; recommended module power 235–440 W. Confirm on the microinverter maker’s compatibility list.

How big and heavy is it?

75.1 × 41.1 × 1.57 in (1,907 × 1,044 × 40 mm), 48.5 lb (22 kg).

Has this panel been reliability-tested?

This exact series is not in published PVEL Top Performer tables; Mission Solar Energy was named a Top Performer in 2 Scorecards (2024–2025).

What fire rating does it have?

UL 61730 fire rating Type 1 per datasheet.
