Frequently Asked Questions


 

What's the difference between greenius and FreeGreenius

There is no difference, it is only the name. Actually the software is called greenius and FreeGreenius is the title of a project funded by the German Ministry for Economic Affairs and Energy with the main goal to publish a free version of greenius. Prior to this project a free version of greenius was also available but that free version had a couple of restrictions and was not a full version. Software versions without these restrictions were only given to partners within joint projects or to a limited number of entities.

In order to make the software available for the public, the project FreeGreenius was defined and thanks to the funding by the German Ministry for Economic Affairs and Energy you may now download and utilize the software.

 

Is there a version of greenius available for other OS than Microsoft Windows?

No, greenius is currently only made for Microsoft Windows XP, 7 or 8 and there are no plans to develop it for other operating systems.

 

Has the software been validated?

Yes. it has been validated but not in a sense that it has been used to compare the simulation results to measurements of a whole year for an existing plant. Owners and operators of CSP plants are quite reluctant to publish detailed operating data of existing plants. Therefore we have only a limited number of measured data for model comparison which does not comprise a whole year of operation. Annother problem is that the available performance data is often not complete in the sense that not all necessary input parameters needed for the simulation are logged with the required temporal resolution. One example for this parameters is the cleanliness of the collector field. greenius uses a mean cleanliness but the cleanliness will vary in time and space and the actual mean value for the whole collector field will be not reported, in most cases.

Futhermore we have compared greenius to other simulation tools for annual performace calculation of CSP plants. This has been done several times and with different tools. The results were quite good and in this comparions we observed that the greenius results were often somewhat lower than the median. This might be due to the fact, that greenius considers thermal inertia of HTF and piping, though it is a staedy state model.

 

How accurate are the datasets delivered with greenius?

We are trying to use published data for technical parts like collectors, absorbers, etc. from supplier datasheets or other publications. Furthermore we try to check these data when possible. Nevertheless we cannot give any guarantee for the data. If you are a supplier and you realize any erroneous or outdated data for your product, please send us an This email address is being protected from spambots.

Greenius does not start because MSVCR71.dll is missing. What can I do?

MSVCR71.dll is a standard dynamic link library of Microsoft Windows operating systems. However it is not installed in some cases. In case you encounter this error please install the latest verstion of Greenius. As of version 4.0.6 the dynamic library is not needed anymore. If this does not solve the problem please send us an This email address is being protected from spambots. You need JavaScript enabled to view it..

 

FreeGreenius

This is the homepage of FreeGreenius. Find the latest news on our news page.

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.


 Acknowledgements

The development and extension of greenius has been funded by several public bodies. Their funding is gratefully acknowledged and they are mentioned in the following paragraphs.

Publishing, further development and user support for FREE greenius is currently enabled trough funding by the German Federal Ministry for Economic Affairs and Energy based on a decision by the German Bundestag (Funding reference number: 0325427)

The addition of models for solar cooling with concentrating and non-concentrating collectors was funded by the European Commission under the 7th Framework Programme (Contract no. TREN/FP7EN/218952)

The addition of models for process heat generation with concentrating and non-concentrating collectors was funded by the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety based on a resolution of the German Parliament (Funding reference number: 0329609A)

The extension of greenius for concentrating PV systems was funded by the European Commission under the 6 Framework Programme (Contract no. SES6-CT-2003-502626)

The development and implementation of greenius started in 1999 and funding was provided by the European Commission under the ALTENER II Programme (Contract no. XVII/4.1030/Z/98-268)
