1. A method for monitoring photovoltaic power generation using remote terminal unit (RTU) comprising:

  • receiving photovoltaic power generation state information via ZigBee wireless communications from a photovoltaic inverter;

    measuring the power of ZigBee wireless communications signals through which the photovoltaic power generation state information is received;

    determining whether the measured power is within a normal range;

    performing transmission power control and low-noise amplifier (LNA) control on the basis of the determination result;

    generating remote message on the basis of the received photovoltaic power generation state information;

    verifying the presence of errors in the generated remote message; and

    transmitting the generated remote message to a monitoring server via Wi-Fi communications in absence of the errors on the basis of the verification result.
