Solar Panel


I Plan to rotate my solar panels through 90 degrees over an 8 hour period. Then they will return to there starting position.

The next morning they must start a new cycle. What is the correct way to synchronise there timing?

Thank you


Much simpler if you just point them at the sun and don’t bother with timing. If you just want East-West movement a couple of light dependent resistors mounted on the panel and 10 or 15 lines of code should do it. Just move the panel towards the brighter LDR.


The correct way to synchronize their timing is with a Real-Time Clock (RTC) chip. There are many to choose from and many examples of code to read them.
