The biggest achievement, and also one of the best features of IoT (Internet of Things) is the ability to monitor devices remotely and take necessary action as needed. This monitoring feature has widespread applications, not the least of which being more efficient generation of energy from inexhaustible sources. And what better energy source than the Sun itself.
At present, the solar photovoltaic (PV) energy is one of the pivotal renewable energy sources. Solar energy is becoming a potential solution towards sustainable energy supply in future. As more and more Rooftop Solar PV Systems are getting integrated in the existing grids, there is even more need to monitor real time data from solar PV plants to optimize the overall performance.
Solar power plants require continuous maintenance and are hence limited in scale. However with IoT technology, we can remotely monitor the functioning of the solar power plant.
A monitoring system is an essential part of a PV plant. It allows the yield to be monitored and compared with theoretical calculations, and raise warnings in case of performance shortfall. This helps to rectify and detect faults before any appreciable production loss occurs. This same fault could take months before it is noticed and rectified in absence of a proper monitoring system, which would lead to unnecessary revenue loss.
In general, monitoring systems have to fetch, analyze, transmit, manage and feedback the remote information, by making the best use of the most advanced communication technology available. It also merges comprehensive use of instrumentation, electronic technology and computer software and has a huge potential in the upcoming years.
