4 Solar Panels are plenty, I have 2 and on sunny days you get much more than you can consume. I would recommend just getting 2 aswell (I got 870Watt peak in total) because everything else would require either some form of battery or would involve giving the energy into the power grid. Also in Germany there is a 800W limit for easier registration aswell.
