Abstract: A photovoltaic module includes: a photovoltaic solar cell module; a junction box disposed on a back surface of the photovoltaic solar cell module, and to convert a DC power from the photovoltaic solar cell module to an AC power; and a first cable electrically connected to the junction box and to output the AC power. The junction box includes an insulating case having an insulating material, and disposed on the back surface of the photovoltaic solar cell module, and a circuit board within the insulating case, and mounted thereon a converter for converting a level of the DC power from the photovoltaic solar cell module, and an inverter for converting a DC power from the converter into an AC power. Th first cable includes first and second conductive lines for outputting the AC power output from the circuit board to the outside, without a grounding line.
