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 Hyundai Energy Solutions HiS-C275RG(BK)?

The Hyundai Energy Solutions datasheet guarantees at least 17% module efficiency for the 275 W class (up to 17.6% for 285 W). 275 W over 1.64 m² equals about 168 W per square meter.

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

PVWatts v8 with typical-year weather gives about 461 kWh per year per 275 W panel in Los Angeles and about 505 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.35 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 18% 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 3–14 panels per string (Voc at 2 °C = 40.6 V, Vmp at 74 °C cell = 25.8 V). Final design must follow the inverter manual and NEC 690.7.

How big and heavy is it?

64.6 × 39.3 × 1.38 in (1,640 × 998 × 35 mm), 41.2 lb (18.7 kg).

Has this panel been reliability-tested?

This exact series is not in published PVEL Top Performer tables; Hyundai Energy Solutions was named a Top Performer in 5 Scorecards (2017–2025).

What fire rating does it have?

UL 61730 fire rating Type 1 per datasheet.
