CanadianSolar/CASSYS

CASSYS is a photovoltaic simulation engine that models energy yield for both standard and bifacial solar systems. It calculates back-side irradiance and applies spectral corrections to improve prediction accuracy. The system includes a VBA-based interface for data entry and charting, along with pre-configured sample sites and climate data for immediate use.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 3 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit b5487bb4e9 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
