CSP Library


Publishing date: February 2014

FreeGreenius is the freely available version of the software greenius which has been developed at the Institute of Solar Research of the German Aerospace Center (DLR) since several years.

It is made for fast and simple performance calculations of Concentrating Solar Power (CSP) and other renewable energy systems based on hourly plant performance simulations. The initial focus was on renewable electricity generation with emphasis on concentrating solar power generated by parabolic trough plants. Greenius is continuously extended e.g. to simulate also solar towers, solar process heat generation and solar cooling. It offers a combination of fast technical performance calculations, economical calculations and user interfaces for parameter manipulation and analysis of the results. Third party meteorological data and performance maps generated with other software tools may be integrated easily.

In the past the publicly available version was restricted in modeling capabilities and only those users who have bought a full version had access to all options. We had many requests from potential users but due to limited resources we could not distribute it. Now we can offer a full version of Greenius for everybody free of charge.
