IOT based solar energy prophecy using RNN architecture

Abstract

It is the 21st century and scientists say that by the end of this century, resources will be replenished and the only way the future generations can access energy is through renewable resources— those which are inexhaustible. One such source is sunlight, which has a guaranteed stay in the long run. The energy thus given is termed as solar energy. In the present paper it is tried to solve the issue of limited resources and their adverse effects. Since the power generated from solar energy systems is highly variable, due to its dependence on meteorological conditions, an efficient method of usage of this fluctuating but precious energy source has to come in picture. This requires the scope of reliable forecast information as the development of predictive control algorithms for efficient energy management and monitoring for residential grid connected photovoltaic systems. The paper has given an overview of different applications and models for solar irradiance and photovoltaic power prediction, including time series models based on live measured data from rooftop solar power plant located at 17.5203° N, 78.3674° E. For experimentation, data collected over four years from the solar power plant was used in order to the train machine and understand the characteristics of the solar power plant and gives the predicted energy as the result. The use of Deep Learning is done where LSTM is used for the training and keras and tensorflow are used for obtaining the result. The mean square error thus obtained is 0.015.

Smart Intelligent Monitoring and Maintenance Management of Photo-voltaic Systems

“…Photo voltaic (PV) cell is a major component that is used to harness solar energy. When connected with other components like battery, charge controller, ac inverters, it forms a PV system (PVS) which can be used to convert the sun's energy to alternating current and voltage signals [4]. The major challenge to wide implementation of solar PVs at a very large scale is the initial cost of installation [5].…”

“…In addition, data collection from a solar plant for over five years was carried out and utilized to build a machine learning model in [11], in a bid to understand the characteristics of solar power plants and give the predicted energy results. In this work, deep learning technique was used for training while Keras and Tensor flow were employed for obtaining the results.…”

Investigation of the Impact of Soot on the Efficiency of Solar Panels using a Smart Intelligent Monitoring System

“…A solar module is made up of linked cells mounted on a frame, whereas an array is made up of multiple modules linked together. It is the component responsible for capturing solar energy and converting it into an alternating current and voltage signal [1]. A photovoltaic system has a typical lifespan of 25 years [2].…”
