Construction of a 12V Standalone Solar Powered DC fan for Solar Energy Utilization

Abstract

This project was embarked on construction of a 12 volts standalone solar powered DC fan for solar energy utilization using constructed DC fan, solar photovoltaic panel illuminated by solar radiation, 12 volts DC battery and connectors. After construction of DC fan, measurements were carried out using 25 volts adjustable DC regulated power supply system to feed in variable voltage and determine the output voltage and the speed of fan at different distance using hand held anemometer. The rate of blowing air of air determined at different input voltage and distance determines its performance ability. Therefore, the performance ability of DC fan determined upholds its utilization at home and office, both in urban and rural areas where grid electricity is not regular or unavailable.
