Response to well a few points...
Solar flares cause power outages by inducing very low frequency potential differences in the earth. These in turn cause low frequency currents to flow in large transmission line transformers which are located sufficiently far apart to experience the potential differences. The currents then cause magnetic saturation in the core of the transformer which causes the excitation current to increase to the point that the protective breakers trip.
Your electronic equipment will be just fine as will your pump motor.
