Do Solar Flares Effect Solar Panels?

Question:

Dear 360Chestnut,

I've been wondering...Do solar flares have any negative or positive effects on solar panels?

Thanks,

Herb



Expert Answer: 

Herb,

The short answer is no, solar flares will have no effect on solar panels. 

The longer answer is not that much different.  Here is what we do know: a solar storm can reduce solar panel performance on a satellite that is orbiting earth by 3% to 5% in a day.  Given that such solar storms are very rare and that satellites are way out in space, closer to the sun, the effect of a solar flare on a terrestrial panel (like on your roof) is between, none and tiny.  The danger of the panel being damaged by wind, rain, snow, a tree branch, an errant ball is far greater than the danger of solar flares. 

I hope this helps,

Harold
