Workflow

How PVMath works — seven connected steps, one project.

One project setup feeds every step. Each result carries into the next — no re-entry, no rebuilding the site in a different tool.

Step 1 — Project Setup
One login · one project context

Name the project, set the country, and place the site once — draw on the map or upload a KML/KMZ boundary. Every step inherits the same project.

Standard & Agri-PV
SiteIQ — Site Screening
Step 2 · Solar · flood · regulatory · buildable area

Screen solar resource, flood risk and grid proximity, then map buildable area with automatic GIS setbacks from roads, rivers, buildings and more.

TerrainIQ — Slope Analysis
Step 3 · Needs a boundary · CAD exports

Region-routed DEM inside your boundary — slope heatmaps, cross-row grades and engineering verdicts before you order a topo survey.

LayoutIQ — Auto Layout
Step 4 · Layout + electrical

Pick Fixed Tilt or tracker, auto-pack rows with GIS setbacks, then size strings and cables — A1 electrical drawing and a PVsyst input file in the project package.

YieldIQ — Yield Estimation
Step 5 · Auto-runs from your layout

PVGIS yield for your chosen LayoutIQ mount — Fixed 1P–4P or SAT 1P/2P. Runs automatically when you proceed, no re-entry.

RevenueIQ — Economic Screening
Step 6 · Uses LayoutIQ capacity & YieldIQ energy

CAPEX bands, tariff revenue, OPEX, LCOE, IRR, NPV, and payback from your layout and yield — country-aware auction/PPA modes and Agri-PV adjustments.
