Yeah a solar flare might temporarily blow out power, ignitions and electronics etc which will be fixed sooner or later, it's already happened quite a few times-
Sep 1859- Telegraph wires burst into flames, touching off fires .Telegraph machines scorched paper printouts, stunned operators with electric shocks, transmitted gibberish, and continued working for hours even after being unplugged from the batteries that powered them. The Earth itself was no longer "grounded"!
November 1882- another massive solar flare lit lamps, disrupted telegraph communications, and set off several fires on the Chicago telegraph switchboard, melting instruments.
November 1903- solar storm not only disrupted telegraphs and the transatlantic cable; it even shut down Swiss streetcars.
March 1940- severe solar storm burnt out fuses and damaged hundreds of miles of telegraph and telephone networks.
March 1989- a major solar flare shorted out Quebec's power grid. Circuits also overloaded in Great Britain, New York and Virginia. A critical transformer melted in New Jersey.
November 2003- an "X" solar flare, the strongest of solar storms, temporarily disabled many satellites, killed one satellite completely and and burned out an instrument on a Mars orbiter. The crew of the International Space Station took shelter, reporting elevated radiation readings and "shooting stars" in their own eyes.
September 2005- a string of "X" solar flares caused lesser disruptions to major power grids and knocked out the GPS system completely for ten minutes.
June 2011- a moderate solar flare caused minor satellite disruption, unusual amount of static on phone lines.

What we can do NOW is to flare-proof a radio so that when a flare blows out the electricity, we'll still be able to tune into the world to monitor what's going on.
Below- I proofed my radio by removing the batteries and wrapping it in a plastic bag, then wrapping it in kitchen foil. (the plastic bag is to keep the radio from touching the foil). It now sits on a cupboard shelf waiting to be unwrapped after F-day (flare day)-
