Cost of Energy (COE): The average cost per kWh of useful electrical energy produced.

Levelized Cost of Electricity (LCOE): A measure used to compare different methods of electricity generation.

Reliability & Sustainability: Assessments of system availability and environmental impact, such as greenhouse gas emissions reduction. Use Cases in Research

HOMER Pro 3.15 has been applied in various recent feasibility studies (2023–2026), such as:

Electric Vehicle (EV) Infrastructure: Optimizing renewable energy integration for EV charging stations, targeting specific grid-to-battery efficiency.

Hydrogen Integration: Modeling PV-hydrogen-diesel hybrid systems for stand-alone residential use in harsh climates like Canada.

Rural & Urban Microgrids: Investigating the shift from diesel-only systems to hybrid wind-solar-diesel configurations to reduce grid dependency and operational costs. Comparative Context

While highly effective, tools like iHOGA are sometimes cited as alternatives because they offer multi-objective optimization (e.g., minimizing both cost and CO2 emissions simultaneously), whereas HOMER Pro often focuses on cost-minimization as the primary driver for its optimization logic.


4. Global Solar Atlas & ERA5 Weather Data Integration

Weather data accuracy is foundational to any renewable energy model. In 3.15, HOMER Pro has streamlined its access to high-quality datasets:

Why this matters: Older versions required manual download and formatting of TMY3 or NSRDB data. 3.15 automates this process, reducing setup errors and improving simulation realism, especially in remote or developing regions where ground data is scarce.
