Helionyx MCP

Helionyx is an open-source MCP server that performs techno-economic sizing of hybrid renewable energy systems. It simulates hourly dispatch for solar PV, wind, battery, diesel, and grid connections, ranking designs by net present cost while respecting constraints. It supports sensitivity analysis, Pareto trade-offs, and exports reports for pre-feasibility studies and rural electrification planning.
