Solar Powered automatic rain operated wiper

Solar Powered automatic rain operated wiper
We have discussed many projects related to solar energy and we are going to discuss many more in the next few months. In this post, we will see how we can use sunlight in an automobile.  

Though this project has been implemented by many companies, it would be great to build one for yourself in a lab or as your final year project. When I was thinking about this project, I thought it would be great if we can build it as an extension of rain sensor wipers project idea. 

It is very easy to build and needs very few components. Rain Operated Motor consists of a conduction sensor(Tough Sensor) circuit, Control Unit, Wiper Motor, and Glass Frame.


We all know that wipers need electricity to move and this electricity has been supplied by a battery inside a car. So, to move wiper using solar power, you just need to supply electricity to this battery or some smaller battery(if you want independent system) using solar panels.

To optimize performance, you can use rain sensor wiper as shown in this video:
