Abstract :
Now a days renewable energy systems are becoming best way to generate electricity. With advancement
of technologies the cost of renewable energy equipments is going down globally encouraging large scale solar
photovoltaic installations. Major part of renewable energy is solar energy. Due to its decentralized nature it is
very difficult to monitor solar power plants with existing centralized SCADA(Supervisory Control And Data
Acquisition) systems. We developed a prototype for implementation of new cost effective methodology based
on IoT to monitor a solar photovoltaic plant for performance evaluation using open source tools and resources
like Arduino and Thingspeak. Thingspeak is a SaaS (Software as a Service ) platform which provides space
on Web to monitor our parameters. Thingspeak provides all services for free of cost. Which saves lot of
investment on Website designing and maintenance. We focussed on low cost system with easy interface so
that common people who installs roof top s
