3.15: Homer Pro
HOMER, which stands for , was originally engineered by the U.S. National Renewable Energy Laboratory (NREL) . It helps project developers, engineers, and researchers design optimal microgrids by comparing thousands of potential equipment combinations in a single run.

To extract the highest accuracy from your simulations, keep these professional tips in mind:
During the optimization phase, HOMER simulates hundreds or thousands of different system configurations. It filters out unfeasible options (e.g., those that cannot meet the electrical load) and ranks the remaining configurations by Net Present Cost (NPC). This allows users to find the exact combination of solar panels, wind turbines, generators, and batteries that minimizes lifecycle costs. 3. Sensitivity Analysis homer pro 3.15
: The software now allows the electric grid to directly supply power to an electrolyzer, enabling better simulation of grid-connected green hydrogen projects. Electric Load Year
The platform relies on a nested architecture combining three distinct operations to guide users toward the most reliable, lowest-cost energy configurations.
: A 2025 case study in Khlong Ruea, Thailand, used HOMER Pro (Version 3.15.3) to design a 100% renewable microgrid for 306 residents. The optimal system integrated 20 kW of solar PV, 9.42 kW of pico hydro, and 264 kWh of lithium-ion battery storage , proving the software's ability to model complex, off-grid renewable-only systems. HOMER, which stands for , was originally engineered by the U
In the accelerating transition toward renewable energy, designing efficient, cost-effective, and reliable power systems is more complex than ever. Whether for a remote microgrid or a grid-tied industrial complex, engineers need precise tools to simulate performance.
HOMER Pro 3.15 builds upon previous versions by refining calculation engines, expanding component libraries, and improving user workflows. 1. Advanced Battery Modeling
