    Are PV panels suceptable to EMP?

    Not in New Hampshire. Not enough EM.

    Good to hear! Panels will be in Warner, NH.

    I know. I should have written *Especially* in Warner.

    You obviously know nothing about the physics of high altitude air bursts...

    Bob, I was pulling you leg with my answers. Forgive me for that.

    The professionals here know what it is all about, but, I can agree with
    them about the susceptibility. You probably only need a few inches of
    wire attached to something to cause havoc in the case of an EMP.

    If you get one, please let us know and we will go underground :)

    EMP is mostly very strong HF, with a initial DC like surge.
    Depending on your distance to the blast, lots of things with a small
    capture area can/will survive. Things like two meter HTs and small
    cell phones are very hard to zap with EMP simulators in the far

    ARRL had a excellent multi-month write-up on this some time. Find all
    three parts of "Electromagnetic Pulse and the Radio Amateur."

    Doing things like wrapping boards in copper foil, and then setting
    them on a insulator inside of a large metal cabinet with bonded doors,
    does wonders.

    And how does it respond to a 50 k volts/meter electric field?

    I have an Alps AP-KC40W/12V here with a label which says:

    Peak Power: 40W
    Maximum Power Voltage: 17.8
    Maximum Power Current: 2.3
    Open Circuit Voltage: 21.6
    Short Circuit Current: 2.5

    Conversion efficiency: 14-16%
    Cells per Module: 36
    Tolerance: +/- 10%

    Dimensions (mm); 651 x 526 x 35

    I measured what I think is the active area. I got 24.75 inches by 18.25

    Measured capacitance:

    F C
    100Hz 215nF
    120Hz 206nF
    1000Hz 117nF
    10kHz 104nF

    I'm sure you are capable of scaling the capacitance vs area. If not,
    someone here can help.

    Please show your reasoning and your calculations.

    The idea is two of everything. You wait till the shooting stops and
    switch to the "B"urried unit.

    I doubt ITO glass has good enough conductivity to be part of a EMF
