PVWatts models a standard roof-mounted module; integrated roof products are not modeled separately.

Estimate for comparison, not a quote: shading, roof orientation and local losses change real output. Roof mount, 20° tilt, south, 14% system losses.

Questions & answers

How efficient is the Sunflare FLEX60 177?

Calculated from the panel area (1.64 m²): about 10.8% for the 177 W class. 177 W over 1.64 m² equals about 108 W per square meter.

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

PVWatts v8 with typical-year weather gives about 297 kWh per year per 177 W panel in Los Angeles and about 325 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.385 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 19.9% below the STC rating.
