Their info on Spain is old. As I understand it the cuts have already gone through.  Plus, the information that I got from offical documents is suggesting that there are at least 100,000 solar PV installations in Spain. Which using information from the national system operator suggests an average solar pv installation size of less than 50 watts. So most of these must be roof top units.
