SUNDI

SUNDI logo.

Developed at the Electrical Machines Institute, SUNDI calculates the irradiance losses due to shading. A simple analysis can be done with sun orbit diagrams. An exact day analysis is possible with this program. Shading situations can be localized exactly. The results can be presented graphically. The irradiance losses can be also calculation for long periods of time. The calculation is very quick. The results are given in a tabular and can be used by other Windows applications.
