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