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 FLEX60-170W-M20-A?

Calculated from the panel area (1.64 m²): about 10.4% for the 170 W class. 170 W over 1.64 m² equals about 104 W per square meter.

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

PVWatts v8 with typical-year weather gives about 285 kWh per year per 170 W panel in Los Angeles and about 312 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.
