And if there's too much sun, where's the extra power dissipated?
You can just open the circuit to disconnect a solar panel from the external load. The panel will get slightly warmer in full sunlight when it's not connected to a load, but there's no harm to it. Since there is no rotating mass or hot steam with accumulated energy in a solar farm, you can shut it down completely in seconds if necessary. Solar PV can safely go from 100% output to 0% faster than any other electricity source.
