Solar Tracker

[km]

Can anybody guide me how to design a microcontroller and sensor based Solar Tracker? :idea:

I need to use a microcontroller. Do you have other option? :roll:

hi
wat exactly r u looking for
is it something like a solarpanel which follows the movement of de sun or any light source 8)

i think he is looking for a sun tracking solar panel system which is controlled by microcontroller... anyone can help?? coz i m doing the same project too...

use a comparator that compares the voltage of each solar panel. Simple. You don't NEED a mircocontroller, but having my mind injected with uC thinking, use one! analog is almost useless compared to a uC!

km,

Two LDR's (light dependent resistors) in series as a voltage divider, mounted on a hobby servo. A small panel seperates the LDR's. Feed the junction of the voltage divider to the ADC input of a uC. Drive the servo with the output of the uC. Program the uC to move the servo to point the LDR's at the sun to maintain equal light on both, so the small panel doesn't shadow one LDR. Use PWM, pulse period, DAC, binary or LED/LCD out from the uC to indicate the sun's position...or mount the LDR's directly on a motorized PV array and use the "error" output to move the array...if that's the end product.

Google solar or sun tracker...lots of other approaches.

In addition to what KMoffet says, take a look at the Taos TSL14S-LF light to voltage converter. Very handy package for the A2D input of a uC. Then let the software handle the motor control, hysteresis, etc.

You can use a green LED in place of an LDR for this sort of thing. There is a *lot* of info on trackers, just Google it.
