Sunlight Availability Data

Can anyone suggest where it is possible to obtain sunlight availability data for Ecotect? The link within the help file takes me to a French website which does not seem to be relevant.
I have tried a myriad of other places and would really appreciate your assistance.

Hi!, I'm having the same problem. Did you find out how to fix it?. I've even try to make a .data file from London in Meteonor but it doesn't work.
