Super interesting! With such a big solar system, the self-consumption is already quite high. With a smaller solar system, the ROI for a battery would probably be higher.
So in itself a big solar system is a nice alternative to batteries.
Curious about the details of the 30kWP solar setup!
The thief of the Ghent Altarpiece was a big fan of the detective books on Arsene Lupin. In real Lupin style, he sent 14 letters to the paintings' owners containing all kinds cryptic hints about the location of the work, before dying unexpectedly. Right before his dead, the thief confesses to his lawyer he had stolen the work. He still tries to give some more details, but it is too late and he passes away.
