Ni hao Gary, Firstly I am sorry but I know nothing about solar energy except that it must be a good idea in Spain and that the laws are changing to make it compulsory for builders to install it on commercial buildings - maybe houses later.
I had a quick look at your site and it seems that some of your products are for huge commercial projects - the home system did not display any information.
There are lots of advertisements in the Spanish papers for solar so people must be buying it - also lots of people have swimming pools here and a system to heat the water when it is not summer may be a good idea.
I think you are probably in the wrong forum here - I searched on google Solar power in Spain and found this site:
http://energy.sourceguides.com/businesses/byGeo/byC/Spain/byP/solar/solar.shtml
perhaps that will help you to make contacts with companies in Spain who are involved with solar power.
Good luck.
