Solar Fan Cap Rerview


This study aimed to found out if solar power can power a fan which can relieve heat from the head by the use of a cap. The energy solar power to chemical energy which is stored in the batteries to wind energy which is the fan to help relieve hotness in the body. The feasibility of a solar fan cap made from cap as a base, solar panels from calculators, and a CPU fan. The cap was cut in the front to place the fan and the solar panels were placed in the topmost portion of the cap.


A solar fan cap can be built from a cap, solar panels and a CPU fan. The person will use the hat in the hot afternoon and turn on the fan for the person’s comfortasbility. The solar panels will charge the batteries and the batteries will power the fan. This project can be easily built by a normal person you just need some time and a good budget.

This solar power is an interesting study in the field of science. We have studied this for almost two months.

  1. Solar Panels: These panels were used to capture light photons and transform it to electricity.
  2. Energy Transmission: Solar Energy to Wind Energy
  3. Renewable Energy: Solar Power


General Objective

This study aims to find out if the sun is enough to power our daily needs and be efficient enough to power the fan which can relieve stress.

Scope and Limitations

This study was conducted for almost 2 months.

Development of solar energy materials were continued in order to be more efficient in the future. It is limited to the availability of the sun rays and light photons.

This project is very simple for us students because new is in. So we like to invent new technology and design new type of products for uniqueness.

This cap can be repurpose from fan cap to charger which can charge our daily gadgets such as cellphones, tablets and gaming devices. It needs a little improvement for its durability and longevity.

Review of Related Literature

Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar energy technologies include solar heating, solar photovoltaics, solar thermal electricity and solar architecture, which can make considerable contributions to solving some of the most urgent problems the world now faces.

Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.



  1. Cap (any type but harder visor is recommended)
  2. Solar Panels (from calculators)
  3. CPU fan


  1. Cut the front visor according to the size of the fan.
  2. Place the fan in the front visor using a hot glue.
  3. Attach the Solar Panels in the topmost portion of the cap.
  4. Connect the panels in a series connection. (This will increase the voltage which will flow to the fan increasing its rpm or speed)
  5. Connect the positive and negative lines to the fan and switch that will regulate the power.

Results and Discussions

After the project is done. We tested it. The results were not great as we expected it appear. The solar panels were charging fast but the fan’s rpm is a little bit slow but there is a flow of air in my head. If I am sweaty enough I would be glad if I had that kind of Equipment which is portable and dual purpose which makes it more interesting.


Our hypothesis was correct. Thou it only produced a small amount of air flow. But in a hot weather it can be useful. Most people will be amazed by this product and try its effectiveness. Because amazingly where did you see a hat with a fan powered by the sun.
