Metering of surplus energy on PV systems using ZigBee Wireless Technology

The method of collecting of Net meter readings by the Distribution Company becomes more problematic and costly when readings have to be collected from vast, and often scattered rural areas. Net Meter readers will commonly submit inaccurate estimations of the energy consumption and export energy. The main objectives of the study is to integrate the surplus energy meter of PV system using zigbee wireless technology. The study was conducted by analyzing the concept of the net metering system and the researchers focus only on measuring the surplus energy to be export. The ZigBee technology was integrated with the meter to measure and monitor the surplus energy produce by the solar panel wirelessly. The ZigBee technology is indeed a convenient way of monitoring and measuring the meter reading wirelessly since it is accurate and reliable based on its performance during the prototype testing. The PV Systems can produced an average daily surplus energy of 0.22489 kWh which can have a peso savings of 1.08835 per day. Overall, the solar panel can produce a total monthly kWh surplus energy of 7.00982 kWh with a total monthly savings of 33.73898 pesos.
