SolTrace 1.0

SolTrace is a software program developed by the National Renewable Energy Laboratory (NREL) that models optical systems and analyzes their performance for concentrating solar power (CSP) applications.

SolTrace is commonly used in the CSP industry, where it assists in the design and optimization of solar collector systems, including parabolic troughs and linear Fresnel reflectors.

SolTrace utilizes a raytracing algorithm to simulate the paths of solar rays as they interact with various optical components such as mirrors, lenses, and receivers. It can accurately predict the distribution of solar energy in a given system.

SolTrace requires inputs such as optical component geometries (curvature, dimensions, etc.), the sun's position, and atmospheric conditions. It also requires information about material properties, reflectivity, transmissivity, etc.

SolTrace provides a range of analysis outputs, including ray paths and intersections, energy fluxes at any point in the system, efficiency calculations, and deviations from ideal optical designs.

Yes, SolTrace is capable of modeling non-linear optical systems, such as those used in point-focus concentrators like dishes or central receivers.

Yes, NREL offers support for the SolTrace software. Users can access the official SolTrace website for documentation, tutorials, and technical support resources.

SolTrace is compatible with Windows, Linux, and macOS operating systems.

Yes, SolTrace is available as an open-source software free of charge.

No, SolTrace primarily operates through command-line inputs and outputs. However, it does come with a basic graphical user interface (GUI) for visualization purposes.
