How Solar Panels Track The Sun

The principle on which these work is that their resistance decreases as the light intensity increases.

How solar panels track the sun. Understanding the sun s behavior is an important part of life in our solar system. Scientists use sunspots to track solar cycle progress. Check out this video of a system designed by arizona man mike davis to have solar panels follow the sun across the sky. Since we want to be able to track the sun we need some form of light detector.

The dark spots are associated with solar activity often as the origins for giant explosions such as solar flares or coronal mass ejections which can spew light energy and solar material out into space. Sunspot number over the past five solar cycles. There are a number of alternatives here but the simplest is an ldr light dependant resistor. Scientists use several indicators to track solar cycle progress.
