Shading

Shading analysis from real drone data.

Precise shading simulation based on real 3D roof models – not cadastral data or satellite estimates.

Project delivery

Your drone photos. Usable project data.

You provide the imagery. We review the dataset, prepare the right measurement and model data, and deliver it so your team can keep working immediately.

Your input
  • Drone images of roof and surroundings
  • Roof location and orientation
  • Time period for shading analysis (daily/monthly/annual)
  • Optional: RTK coordinates for positional accuracy
Your output
  • 3D model with obstacles (chimneys, dormers, trees)
  • Shading matrix for PV*SOL/PVcase
  • PV software-ready import (3DS format)
  • Annual yield forecast basis
  • Orthophoto + diagnostic report
Target software
  • PV*SOL premium
  • PVcase
  • Eturnity
  • Solar.Pro.Tool

Project use

Why real 3D data beats satellite estimates

Satellite and cadastral data cannot capture local obstacles: not the trees beside the roof, not the structures on the neighboring building, and certainly not the roof-mounted equipment itself. This leads to shading forecasts that can deviate from reality by 20–30%. With real drone data and 3D reconstruction, you capture every shadow-casting object – and achieve a yield forecast accurate to 3–5%.

The result: Better proposals, more satisfied customers, lower risk of claims. Meanwhile, you save time during planning because the shading matrix is already imported into PV software and ready for layout design.

Typical use cases

  1. Yield forecast with real shading data instead of satellite/cadastral estimates

  2. Existing roof analysis including trees and neighboring structures

  3. Quick proposal preparation with pre-calculated shading matrix

  4. Dispute resolution: documentation of actual shading for expert reports
