Monitoring and Control of Residential Roof Top Solar PV power plant through IoT

Abstract

The objective of the proposed work is to collect, analyse and control number of parameters being
measured from a residential rooftop solar photo voltaic (PV) power plant and to intimate its performance to the
user with the help of arduino and raspberry pi. In order to ensure the stable and reliable operation of a PV system
an effective monitoring system is most vital. The monitoring system has to keep track over various indices and
fault occurrences. Major aspects of a PV monitoring system are sensors and their working principle, certain data
acquisition system and, transmission methods and its storage. Sensors such as Light Dependent Resistor (LDR),
Thermistor and Gravity Tilt Module are used to track data from the solar panel and connected to arduino for
buffering. Then, data obtained continuously from the solar panel will be transmitted to raspberry pi after arduino.
User friendly information is transmitted with the help of raspberry pi. If user desires he can control the PV system
via Wi-Fi module in the raspberry pi or through Internet of Things (IoT).
