This solar tracker system uses the Arduino UNO board, a servomotor, 2 LDRs and 2 resistors to rotate the solar panel towards the Sun or a source of light. Here https ...

The solar panels are operating at optimal parameters when they are at the perfect right angle to the sun. Unfortunately this is accomplished only if solar panels are rotated by the sun. This is the ...

Let’s face it — solar panels still aren’t that efficient. So why not pump as much juice out of them as possible? Building a 2-axis solar tracking unit can increase daily power output by around 30%!
