Python Wrapper for the System Advisor Model

bifacial_radiance

Toolkit for working with RADIANCE for the ray-trace modeling of Bifacial Photovoltaics

wex

WEX, which is short for WxWidgets Extensions, is a cross-platform library of graphical user interface tools that extends the popular open-source project WxWidgets. WEX includes many features including the powerful DView program (https://github.com/NREL/wex/wiki/DView), which provides an easy-to-use way to visualize complex time series data.

elm

ELM is a collection of utilities to apply Large Language Models (LLMs) to energy research.

lk

LK (Language Kit) is a simple but powerful scripting language that is designed to be small, fast, and easily embedded in other applications. The core LK engine, including lexical analyzer, parser, compiler, and virtual machine is only dependent on the Standard C++ Library (STL), making it extremely lightweight and portable.
