My Solar inverter has been showing a frequency slightly higher than 50Hz (only by a few hundreths of a Hz) but I don't know how good the calibration is in it; perhaps it's a bit optimistic. Of course, it's only measuring during daylight, so no help if the slowdown is happening at night .....

EDIT: If anyone reports a self-correction over the next few days, I'll check my own readings and they should be higher than recently.
