INTRODUCTION
A solar inverter helps devices that run on DC power to run in AC power so that the
user makes use of the AC power. If you are thinking why to use solar inverter
instead of the normal electric one then it is because the solar one makes use of the
solar energy which is available in abundant from the Sun and is clean and pollution
free. Solar energy currently represents the most abundant inexhaustible, non-
polluting and free energy resource that could be used economically to supply
man’s increasing energy demand (Nasir, 2004). Over the years, there has been a
grea

Background of study
A solar fan is a mechanical fan powered by solar panels. The solar panels are
eithermounted on the device or are installed types are also used for heating
purposes. It runs the fastest when it is the hottest outside providing savings on
air conditioning costs. Solar-powered fans use a solar panel to generate the
electricity needed to turn the fan motor. One common application is for
attic ventilation. Because the solar panel provides the most energy when the sun
is hottest, the fan moves more air at the time of highest need. Solar panels consist
of photovoltaic cells. As light hits the solar panel, it forces electrons to move
through a circuit, creating electrical energy. Each photovoltaic cell consists of two
layers, which have positive and negative charges like a magnet. The manufacturer
then links enough of the cells together to produce a panel large enough toprovide
the power to turn the fan. Homeowners often prefer using solar fans for attic
space because there is no need to add electrical wiring to power the fan.
Instead, the solar panel provides about 10 volts to operate the motor and turn
the fan blade. Because the installation is on the rooftop, many homes provide the
unobstructed sunlight the fan requires to operate.
Aim and objectives:
The main aim of this project is to ensure steady ventilation in technicaleducation
department offices. The aim of this research work is to develop a solar
poweredstanding D.C. fan that can be used for both urban and rural areas. Also,
this research therefore isaimed at achieving the following objectives:
I. To minimize the problems encountered due to the lack of adequate power
supply.
II. To fully utilize our abundant energy source, that is sunlight.
III. To perform several functions for home owners and office workers.
IV. To determine the efficiency of the design using mathematical model.
V. To reduce the over reliance on alternating current.
VI. To simulate the behavior of solar powered standing D.C. fan design. Client:
The beneficiaries of this project include, Technical education tutorial and non
– tutorial

Working principle:
Its working principle mainly relies on the solar panel to convert light energy into
electrical energy, then store the electrical energy through the battery, and finally
drive the fan motor to operate, thereby generating wind. The solar panel generates
current and voltage under light, charges the battery, and the battery outputs
electrical energy to the load, that is, the fan motor.
When using a solar fan, you need to ensure that the solar panel can receive
sufficient sunlight to avoid shadows. At the same time, the device should be placed
on stable ground or on an appropriate bracket to prevent tipping or damage. Clean
the dust and dirt on the solar panel regularly to maintain its power generation
efficiency. When used in hot weather, pay attention to the operating status of the
fan and avoid prolonged exposure to the sun. When the solar fan is running, do not
touch its moving parts directly to avoid burn accidents.

CONCLUSION:
In this project, a table fan powered with a 30-watt PV module of solar panel was
designed. The design was necessitated by the need to have a fan that could be
powered with a renewable energy source. A 12V DC battery was included in the
design as a source of power backup for use when there is no sunlight-in
the night. In order to achieve a minimum consumption of power, the fan
was made not to oscillate but rather was made such that it could be manually
tilted up and down to change its orientation. The design is quite effective as it
blows a large volume of air (100 cfm) at low speed (500rpm). As a result, the
design is expected to be relatively noiseless and energy efficient
