SOLAR PV CONTROL SYSTEM.pdf

CHAPTER 1
Introduction
The Solar PV (photovoltaic) control System with Zigbee module, aim of the project is
to utilize the solar energy, monitor the energy generated and incorporate its usage
in the grid system. In this project I shall be using various sensors, controlling and
display.
However, in this project work the basic signal processing of various
parameters are temperature, lux readings, panel position, and energy produced
which are the key elements for the grid implementation. For measuring various
parameters values, various sensors are used and the outputs of these sensors are
converted to control the parameters of the panel and data analysis. The control
circuit is designed using micro-controller (Arduino). The outputs of all the three
parameters are fed to micro-controller. The output of the micro-controller is used to
drive the PV panel.
I shall be developing new control systems using advanced communication and
information technologies to manage and use energy more intelligently. Intelligent
control can allow energy systems to respond to their environment and make
operating decisions based upon achieving specific energy goals.
Statement of Problem
Solar P.V systems are widely used in the world. In high altitudes (like Nyeri), receive
minimal sunlight thus resulting to underutilization of P.V capabilities. It’s also hard
to monitor the usage of the energy stored and its use in a household or institution
thus reducing its efficiency.
Reliable electricity in Kenya is an oxymoron. Blackouts have been a norm in Kenya
due to inconsistent supply of energy (electricity) and high demands. Due to this,
solar power can be implemented in the grid system for constant supply and energy
efficiency. It is also a cheaper way to produce energy as solar energy is renewable.
