But that doesn't mean the same isn't going to happen with solar, luckily PV is spread out all over but weather can over a few hundred kms be quite different.
The connection of PV to the grid is also regulated via the Voltage, regulations allow a fluctuation of 10%, as soon as that 255V barrier is reached the PV plant has to throttle or even switch of.
That's one reason I've put in bigger wires for my own, to keep the Voltage as low as practically possible and continue output for the maximum.
For me it's only a 50mtrs stretch (x2!) but I already gain some 5 Volts, for the power company with kilometers to the next transformer it is standard proper engineering practice.
