Plugin solar is entirely different.

My family got an fixed three phase setup with a 12kWp, 8 kWh battery (BYD) and a Hybrid Inverter (SMA) alongside a Level 2 22 kW EV charger for a grand total of 16.000€.

My plugin solar setup was a DIY with 1kWp of panels + an 800W inverter and did cost a total of 350€, including the mounting hardware.
