Solar: What model of blocking diodes??

Discussion in 'General Questions' started by Cottersay, Dec 4, 2018.

  1. WindyNation has a great FAQ on replacing a faulty blocking diode on a solar panel, yet they do not mention with what model or even what specifications the diode should be!
    I have (twin) 100W poly panels with the 20 amp PWM controller; what spare part diodes should I purchase? Thank you!
  2. Does WindayNation not monitor their own forums?? This seems like a really easy question to answer.

    I'm not on here too much.
    A 10 amp 1000 volt diode will work just fine.
    1 for each panel.
    Some panels use more than 1 blocking diode.
