Computer implementation of the models in solar energy engineering is very important. This paper summarized the models and realized them by ArcGIS/MATLAB/ SQL Server/ VC++ mixed programming. The experimental results show that it is feasible to apply mixed programming in solar energy engineering. The storage and management of solar energy data are of good performance. The implementation brings convenience for the solar energy reasonably utilization. Further, it puts forward a new direction for solar energy data analysis and calculation.
