1. An apparatus for diagnosing an under-performing photovoltaic element, the photovoltaic element functioning to convert solar energy to electricity and including a face receiving the solar energy, the apparatus comprising:

  • a by-pass diode electrically connected in parallel with the photovoltaic element, the by-pass diode operating between first and second states, the first operating state of the by-pass diode corresponding to a functional condition of the photovoltaic element, and the second operating state of the by-pass diode corresponding to a dysfunctional condition of the photovoltaic element; and

    an indicator electrically coupled to the by-pass diode, the indicator including first and second modes, the first mode of the indicator signifying the first operating state of the by-pass diode, and the second mode of the indicator signifying the second operating state of the by-pass diode.
