Runs from LayoutIQ
YieldIQ uses your selected LayoutIQ configuration — mount type (Fixed Tilt or Single-Axis Tracker), portrait count, GCR, pitch, and loss assumptions. It does not ask you to re-enter mount settings.
When you open the Yield step, analysis runs automatically for your layout row. Typical uncertainty vs bankable studies: ±8–15% depending on site and assumptions.
Key outputs
- Specific yield — kWh/kWp/year; normalizes sites for fair comparison
- POA irradiance — plane-of-array resource for each mount type
- Performance ratio (PR) — system efficiency including cumulative losses
- Capacity factor (CF) — annual utilization of nameplate DC capacity
- Shading & total loss — row shading from GCR plus PVGIS physics derates
Ground coverage ratio (GCR)
GCR is module collection area divided by ground footprint. Higher GCR increases DC density but raises inter-row shading. YieldIQ models shading from your GCR sliders; trackers include backtracking benefit versus fixed tilt at the same GCR.
SiteIQ / LayoutIQ capacity screening uses indicative MWp/ha bands — separate from the GCR and pitch in your chosen layout row.
Screening vs analysis profile
SiteIQ uses a lighter PVGIS screening profile for speed in combined reports. YieldIQ uses disclosed soiling, other losses, and GCR shading for a richer analysis profile. Both are preliminary — not substitutes for PVsyst, independent engineer review, or lender models.
