PVsyst is designed to be used by architects, engineer, and researchers. It is also a very useful educative tool. It includes a detailed contextual Help menu that explains the procedures and models that are used, and offers a user-freindly approach with guide to develop a project. PVsyst is able to import meteo data from many different sources, as well as personal data.

Features
Meteonorm included
Direct search for a location using Google Maps
Full Meteonorm interpolation program for any location on earth
