Abstract
Electrical energy and water are two major things
whose demands are very high globally. In order to
meet these demands, the production of electrical
energy has now been shifted more towards
renewable sources of energy like solar, wind, tidal
etc. The crisis of water has also become a global
concern. In this modern era where everything is
getting automated, agriculture is an area where both
electricity and water are very essential. In order to
use electricity and water effectively and efficiently,
an automated solar powered agricultural pumping
system can be fruitful. Cost effective solar power can
be the answer for all our energy needs. Solar
powered smart irrigation system is an answer to the
needs of farmers. This system would control the flow
of water all across the field, from water reservoir to
the crops. It is the proposed solution for the present
situation of agriculture. This system conserves
electricity by reducing the usage of grid power and
conserves water by reducing water losses. This paper
discusses about solar panels, battery, charge
controller, voltage regulator, inverter, submersible
pump, water level controller, microcontroller,
moisture sensor, humidity and temperature sensor
and GSM. The goal is to design such a system which
is capable of using water and electricity as per the
requirements and providing an easy solution to the
existing issues.

1. Introduction
The system consists of electrical part and
mechanical part. The electrical part consists of
photovoltaic solar panels, which is meant to generate
electrical power and the power is stored in the
rechargeable battery.
The power is utilized to operate the pumps. The
mechanical part consists of pumps which will
maintain the flow of water. The parameters in this
work are soil humidity condition, water level
condition and the position of the Sun. The solar
panels are used to generate electrical energy which is
supplied to the entire system and it is much cheaper
than the grid electricity. It is suitable to the rural area
that is why the solar system is used as a power
supplier to replace DC motor electricity source. The
initial cost of solar installation is higher than use of
DC electrical motor but the solar system has no bill
compared to grid electricity which has a bill to pay
every month. It is a versatile source of renewable
energy that can be used in any application. The
system consists of hardware and software. The
integration of the two parts makes the system which
provides the results. The hardware system consists of
the sensors, and drivers. In hardware design, we need
all the components that are necessary to accomplish
the project, and these components are solar panel,
water pump motor, sensors, some controller circuits,
driving circuits and some minor components like
tank and reservoir.
