In greater scale, meaning power plants not the PV installed at houses, these things are taken more seriously and after purchase of equipment the control and automation of plant are in your hands. For example, Woodward, ABB have products with capacity up to 0.5 MW of single inverter.
Micro inverter for each panel would be very costly. In 1 MW plant you will have around 4000 panels, communicating with that amount electronic devices would be a headache.
