We have been developing solar energy software since 1975.  Over the years many differents models have been developed.  Some are for solar thermal panels, solar water heaters, solar radiation, shade analysis, and economic analysis.  In addition we have also worked quite a bit with TRNSYS and DOE2.1, a general thermal analysis model and a building model. 

 

At this time we are converting, rewriting, and expanding nearly all previous work to operate over the Internet and run inside browsers, independently of computer type, and in multiple human languages.

Below are links to some of this software.  Please keep in mind that everything is in a developmental form and not ready for prime time, but you can see what is evolving.
