Introduction

Renewable energy source is a practical solution to address the persistent

demand supply gap in the power industry.

Due to the availability of solar energy across the country unlike other

renewable sources which have geographic limitation ,Solar Photovoltaic among

all renewable sources is proving to be most beneficial.

Application of IoT is proving to be beneficial for monitoring power

generation from renewable energy sources.

India is blessed with abundance of solar radiation that attracts massive solar

photovoltaic power plant installation.


Solar Power Plant

• PV modules

• Junction box

• Fuses box

• Wiring

• Inverter

• MPPT

• Temperature sensor

• Reference solar cell

• Pyranometer

Components of grid connected photovoltaic systems


Monitoring goals of a Solar Power Plant

Diagnose performance issues in the PV array or, inverter i.e.,

soiling, incorrect alignment etc.

Optimize solar farm operations and maintenance, mainly panel

cleaning schedule;

Evaluate selection of equipment and installation such as performance

compared to name plate ratings;

Evaluate long-term system reliability i.e., long-term reliability

and performance, inverter failure rate etc.

Evaluate solar power plant design, basically actual solar farm

performance compared to expected

Internet of Things (IoT) The Internet of Things (IoT) is the network of

physical objects or "things" embedded with electronics, software, sensors, and network connectivity, which enables these objects to collect and exchange data.

Relates users and their smart devices along with sensors used in every day actions e.g., Smart phones and wearable devices) .

IoT is expected to greatly transform the energy sector by improving the Consumer side-Generation side relationship.

Background of the Internet of Things


Application of IoT for Solar Power Monitoring and Control

The internet of things has been considered the third revolution in the digital technology after the computer and the internet

•IoT utilizes computing facilities and software systems for information processing and knowledge digging.

•Using IoT Human to Machine and Machine to Machine information exchange and seamless linkage of information flows can be achieved.

•Using IoT real-time control ,accurate management and intelligent decision-making of the physical world can be made.
