Theo, Harry and Timofei in Italy created an efficient and affordable solar panel

The students designed the panel to make reusable energy more appealing. Using the BBC micro:bit’s light sensors and servos, their solar panel moves to always face the sun, improving productivity and efficiency. The do your :bit judges felt this was a smart, scalable solution.

Theo, Harry and Timofei won the working micro:bit category for 8 to 14-year-olds in Europe. They aimed to solve a problem related to Global Goal 13, Climate Action.

Students with micro:bit

We see these solar panels everywhere now. Normally they are fixed in one place. So they don’t always face the sun. We wanted a way to make them track the sun, to follow it in the sky, just as some plants do.
