Adopting Renewable Energy technologies is one advance way of reducing the environmental impact. Some of the private industries establishing their own solar energy power plants and they are selling power to Government electricity boards. Government is also Motivating private sectors for start these type of power plants for resolving power crisis problems in state. The prices of this renewable energy equipment are decreased due to advancement of technologies motivating huge scale solar photovoltaic installations. Power generation from the Solar Photovoltaic plants is variable due to changes in solar light intensity, temperature and other factors. Every solar photovoltaic solar array should be monitored to know its current status because monitoring is very essential for performance evaluation as well as controlling panels to work in a better condition. Currently this power plant is monitored by PLC. So, all records of energy are can be monitored only on site or plant on SCADA Device. In this Proposed work, we are going to develop a model of online solar power monitoring as well as controlling so authorized person can monitor or control panels remotely by home also. The performance, monitoring and maintenance of the plant will highly enhance by using the IoT based Technology for observing and controlling solar photovoltaic plant. Internet of things is a combination of various technologies.
