You also need to transport the power to where it’s needed, and transporting electricity over vast distances is a bit of a challenge that incurs inefficiencies such as power lost to heat.
More importantly though, if you install the solar panels in Spain, then pipe the electricity to Germany, where it’s consumed in factories, then germany would effectively make itself dependent on Spain and every country between spain and germany (for the cables). That’s a geopolitical risk, in case an international conflict ever breaks out again.
