Knowledge Centre

Practical engineering guides for ground-mount solar screening — written for EPCs, developers, and civil teams. Concepts only; no substitute for project-specific survey or bankable studies.

Screening-grade by design. PVMath modules accelerate early site selection. Commission LiDAR, RTK, or lender-grade yield models before FEED and procurement.
TerrainIQ

Regional DEM routing — EEA, FABDEM, 3DEP

Best public elevation source per location; GLO-30 fallback. Not one global dataset.

TerrainIQ

Native DEM vs 5 m output grid

Why satellite posting (~10–30 m) differs from your 5 m analysis grid spacing.

TerrainIQ

Mean slope vs cross-row slope

When average grade misleads tracker projects — and what to check instead.

TerrainIQ

Reading terrain scores & verdicts

How to use summary indices in executive conversations without over-interpreting them.

TerrainIQ

LandXML, DXF & CAD exports

Importing UTM surfaces, contours, and parcel linework into civil workflows.

SiteIQ

Understanding SiteIQ screening

Solar resource, GIS buildable area, flood flags, regulatory pointers, and PVMath Score.

LayoutIQ

LayoutIQ — auto layout & capacity

Fixed tilt or tracker rows on buildable area — pitch, GCR, 3D preview, DXF export.

YieldIQ

YieldIQ — yield on your layout

PVGIS yield for your LayoutIQ mount — specific yield, PR, and capacity factor.

Screening vs survey-grade data

What you can decide early — and what still requires field survey or bankable models.
