It is based on a 1960s vintage tv antenna rotator driven by 21st century microcontroller technology.
Build sun tracker solar panels.
Also we explored the benefits of panel mounts that track the sun.
I had seen other solar panel tracking systems on the web based on antenna rotators.
Tom moates guide shows you how to build a manual solar tracker cheap rugged.
It was pretty easy to build.
The solar tracker itself can be built using many different mechanical kits including lego and knex but the servo used here has enough torque to allow the solar panels to be directly mounted to a panel which is then mounted to the servo.
This means that the panels must be angled towards the sun for each season and throughout the day as the sun rises and sets to get the maximum input from the sun.
Place the piece on the solar panel so that the dowel is in the exact center of the array and temporarily tape it in place.
Adjust the panel until the dowel has no shadow whatsoever around it and your solar panel is now facing head on into the sun.
My plan is to make several and have a ground mounted system at my.
This web site shows how i did it.
This is my home made solar panel sun tracker.
