• Testing Board
  • Type
    • Schottky diodes
    • Reverse bias to use the reverse leakage current to bypass, Schottky diodes have a relatively large reverse current suitable for this purpose
  • Voltage
    • Solar cells chosen have an open circuit voltage of 2.7V, so 20V breakdown voltage Schottky diodes are chosen lol
  • Thermal
    • Thermal runaway risk of solar cells and power losses from diode
    • No need to be considered for testing board

    • Min quantity 1
    • Capacitance not considered
    • Current needs to be greater than short circuit current
