[RE-wrenches] Solar flares

2012-04-28 Thread Hilton Dier III
It's my understanding that the threat of solar flares primarily to the grid and devices connected to the grid. When the charged particles from the sun hit our magnetosphere that induces voltage in long power lines. Since we have satellites (SOHO and ACE) at the first Lagrange point in between t

Seems the predicted 2012 Carrington Event could have some "interesting" side effects. Wondering how PV panels themselves might respond, and if the existing input stage protection (6 kV IIRC) on charge controllers and inverters would protect them? http://www.newscientist.com/article/mg20127001.
