Bying a solarpanel

There was a huge solar panel standing on the Zand square in Bruges. In short, one can invets in solar panels which are placed on the roof of a compagny. In toatal there are more then 3000 panels for sale. You can buy min 4 and maximum 16. From this you will get the benefit of the produced electricity without having them on your own roof , which i think is a good alternative.
