3.15 — Homer Pro

is a major update to the world’s leading technoeconomic modeling software for microgrids and hybrid power systems. Originally developed at the National Renewable Energy Laboratory (NREL) , this tool has become the global standard for engineers and researchers designing off-grid and grid-connected systems. Key Features in Version 3.15

: This version emphasizes the ability to link with MATLAB to run custom dispatch strategies. Users can write their own control logic in M-files to manage how a system operates, which HOMER Pro then executes during its hourly simulations. homer pro 3.15

Windows 10/11 (64-bit), 8 GB RAM minimum (16 GB recommended for large simulations), 1 GB disk space. No native macOS version, but runs well under Parallels or Wine. is a major update to the world’s leading

Providing power to remote villages where grid connection is not feasible. Users can write their own control logic in

HOMER Pro continues to lead by nesting three powerful capabilities into one interface:

HOMER Pro 3.15 is more than just a calculation tool; it is a strategic asset for the energy transition. By providing a clear financial and technical roadmap for hybrid power systems, it empowers engineers to build cleaner, more resilient energy infrastructures with confidence.

The scripting capabilities in HOMER Pro 3.15 have been significantly upgraded. The Python API now allows for:
