The SolarLab Simulator

Model the plant before you build it.

Configure a site, test the energy path and receive a transparent preliminary yield estimate.

Illustrative SolarLab simulation output showing a utility-scale solar plant with resource, array, storage, grid and site annotations — Preliminary plant overview · illustrative output

Build a scenario

Set the assumptions. Watch the complete solar cycle.

Configure the plant in the collapsible panel, then follow the sun and moon along the same energy path while the model is calculated.

A useful first answer, with its limits visible.

The model combines PVGIS 5.3 multi-year resource data with a representative hourly profile, then applies editable SolarLab assumptions in sequence. Storage dispatch follows physical power, energy and state-of-charge constraints.

Detailed horizon and shading geometry, terrain, manufacturer curves, lifetime degradation, grid studies and uncertainty analysis require a project-specific engineering assessment.
