Questions & answers

How efficient is the Heliene 132HC-485 M10 SL?

The Heliene datasheet guarantees at least 20.4% module efficiency for the 485 W class (up to 21.1% for 500 W). 485 W over 2.38 m² equals about 204 W per square meter.

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

PVWatts v8 with typical-year weather gives about 813 kWh per year per 485 W panel in Los Angeles and about 890 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.34 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 17.6% 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 2–12 panels per string (Voc at 2 °C = 48.4 V, Vmp at 74 °C cell = 31.1 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 48.4 V vs max input 60 V; Vmp when hot 31.1 V vs MPPT low 28 V; recommended module power 265–570 W. Confirm on the microinverter maker’s compatibility list.

What does the warranty cover?

15 years on the product and 25 years linear on performance (manufacturer datasheet).

How big and heavy is it?

82.4 × 44.6 × 1.38 in (2,094 × 1,134 × 35 mm), 59.5 lb (27 kg).

Has this panel been reliability-tested?

132HC-M10-SL was a PVEL Top Performer in 2022, 2023, 2024 (HSS, LID+LETID, PID).
