What screening-grade is good for
- Portfolio ranking and go/no-go conversations
- Client and landowner meetings with credible maps and metrics
- Early layout exploration and CAD starter surfaces
- Comparing fixed tilt vs tracker configurations at a location
- Identifying sites that deserve deeper spend on survey and studies
What screening-grade is not
- Stamped civil grading or pile foundation design
- Official flood zone determination
- Legal or planning approval
- Lender or tax-equity bankable energy assessment
- Sub-centimetre as-built verification
Typical upgrade path
- PVMath screening — SiteIQ + TerrainIQ + LayoutIQ + YieldIQ on shortlisted sites
- Field survey — LiDAR or RTK for terrain; boundary confirmation
- Specialist studies — hydrology/flood, geotech, interconnection
- Bankable yield — PVsyst or IE-reviewed model with confirmed layout
- FEED / procurement — detailed design on survey-grade inputs
Every PVMath PDF and export includes screening disclaimers. Treat them as part of the
product design — they protect your team and set client expectations correctly.
Module-specific limits
TerrainIQ: Region-routed public DEM (~10–30 m native); 5 m grid is resampled output.
LayoutIQ: Conceptual row packing — not detailed electrical or civil design.
SiteIQ: Flood flag is heuristic; regulatory text is indicative.
YieldIQ: PVGIS-based; shading from GCR engineering approximations.
