Generally no. Solar events will affect nothing but long lines, blowing up transformers on the grid. They are very low frequency magnetic field fluctuations which is why the long line is needed to generate current.
EMP is the opposite, extremely high frequency electric fields. EMP can also contain lower frequencies but not significant magnetic fields. The high frequency electric fields can be picked up by very short antennas and damage all sorts of electronics including semiconductors.
They are both serious threats but different and require different mitigation. The best way to mitigate EMP is missile defense.

In light of this information, the Executive Order seems, well, curious....
