API calculation

SolarFarmer API v7 was released.

New features

• Custom tracking rotations can now be provided directly via the API — per-tracker for 3D calculations, per-layout for 2D (docs)
• New CSV output files for tracker rotation and incidence angles (available for both custom and default rotation algorithms)
• Performance and scalability improvements for large 3D simulations
• DC ohmic resistance can now be specified in API inputs for more accurate wiring loss calculations

Bug fixes

• Fixed incorrect transformer loss attribution in multi-transformer 3D calculations (API v6)
• Fixed failures in IV curve aggregation for 3D workflows with power optimisers
• Fixed overestimation of DC ohmic resistance in 3D calculations with power optimisers

Deprecations

• API versions 3 and 4 have been removed
