Questions & answers

How efficient is the Mission Solar Energy MSE385SR9S?

The Mission Solar Energy datasheet guarantees at least 19.1% module efficiency for the 385 W class (up to 19.4% for 390 W). 385 W over 2.02 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 645 kWh per year per 385 W panel in Los Angeles and about 706 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.38 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 19.4% 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 = 51.7 V, Vmp at 74 °C cell = 32.4 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 51.7 V vs max input 60 V; Vmp when hot 32.4 V vs MPPT low 29 V; recommended module power 235–440 W. Confirm on the microinverter maker’s compatibility list.

What does the warranty cover?

12 years on the product (manufacturer datasheet).

How big and heavy is it?

78.7 × 39.7 × 1.57 in (1,999 × 1,008 × 40 mm), 50.7 lb (23 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).
