Monitoring Photovoltaic (PV) parameters is very important to see the performance of a PV in producing electrical energy. The energy produced from PV is greatly determined by changes in solar radiation and temperature from PV. The energy produced will vary according to the level of solar radiation and temperature changes. Monitoring in real conditions is required to improve reliability, evaluation, implementation and costs. Aside from that, the description of the characteristics obtained is also useful for determining the design of PV installation configurations and the determination of control algorithms to match the load requirements. So that the electric energy produced can be maximized and the efficiency of PV can be increased. This paper describes a technique for monitoring PV parameters (current and voltage generated and temperature on PV) using wireless nRF24L01 as a communication device between PV and PC as host. PV parameter monitoring uses the ACS712 current sensor, the voltage sensor uses the concept of a voltage divider and a DHT11 sensor for temperature detection. The parameters obtained (current and voltage generated and temperature on PV) are processed using Atmel AVR ATmega 328 MCU which is then transmitted to a PC using the nRF24L01 transceiver system as an intermediary. The test results show that the system built can monitor PV parameters in the form of voltage, current and temperature in real time.
