PV Shade Profile
Shade Block Coordinate Generator
Calculates solar shade block coordinates for use in AutoCAD and design drawing packages. Outputs a complete set of coordinate points for a given obstruction geometry.
  • Solar geometry — altitude & azimuth based
  • AutoCAD-ready coordinate output
  • Adjustable tilt, row spacing, and obstruction height

Built for practical use

These tools are inspired from programs I initially developed for my personal use over years to support my solar PV design and analysis work. I thought it would be useful to the community as a whole so I have built new lightweight browser-based versions for public use. They run entirely in the browser — no account, no server, no data collection. Results are estimates based on modelled inputs and should be independently reviewed before use in design decisions.

Developed by Taylor Scott, solar PV professional / consultant based in Ontario, Canada.
