The present invention belongs to the communication technology field, and provides a wireless communication method for photovoltaic generation monitoring and a wireless terminal for photovoltaic generation monitoring. The method comprises: decrypting pre-receiving first linear frequency modulation and spread spectrum signals, obtaining decryption message, extracting user data from the decryption message, determining a target serial port address, assembling the user data to the serial port message according to the pre-obtained serial port protocol format, transmitting the serial port message to a target serial port address, and verifying the monitoring data fed back by the target serial port address, if the verification is successful, packing the monitoring data and the identity identification to data message according to the pre-obtained communication protocol, performing encryption of the data message to form encryption message, and converting the encryption message to second linear frequency modulation and spread spectrum signals for transmission. The wireless communication method for photovoltaic generation monitoring and the wireless terminal for photovoltaic generation monitoring can improve the information transmission efficiency, ensure the transmission distance, avoid damaging of a communication cable and reduce the communication interference and cost.
