Saja, I would recommend that you start with JUST Type9 and an online plotter. Use the online plotter to make sure that the data reader is reading what you think it is reading. It can be tricky to get the data reader settings correct. For example, you do not want to interpolate solar radiation readings. You can interpolate temperature and other readings. There are also a number of parameters that tell whether the data in the file is given as average values over the data interval or instantaneous values reported at the end of the interval. Once you are certain that Type9 is reading the file in a way that makes sense then look very carefully at the Type16 parameters, especially if your data file does not start on January 1 at midnight. One of that parameters asks for the starting day of the simulation. Others ask whether the data being read is in solar time or local (standard) time and if it is in local time, what the difference in longitude is between the data file location and the standard longitude for the timezone. These must all be set correctly in order to avoid the kind of problems that you are seeing. If you are really stuck after working to get the parameters set correctly then you should send the project and data file to your distributor for assistance.
