1. A day-night photovoltaic system, comprising:
a solar panel configured to convert solar energy into an electrical energy;
a direct current (DC) power supply part having a positive terminal connected to a negative terminal of the solar panel, a negative terminal which forms an output voltage PV together with a positive terminal of the solar panel, and at least one external input terminal configured to receive an external input voltage,
wherein the DC power supply part comprises a switching mode power supply (SMPS) which is configured to receive the external input voltage, wherein the SMPS is configured to receive an alternate current (AC) as the external input voltage and convert is to a DC current, and the SMPS is configured to receive a DC current as the external input voltage and convert it to an AC current.
