Solar Freaks

hi there every1...

I have a slight problm...
i am working on a dual axis solar tracker..(an aparatus to track the sun and produce maximum output voltage; open circuited)...

now i was thinking whether i should work on the same project and inculcate a MPPT stuff into that so that i have max power deliverd to the load i put...

for that i have chosen a simple dc/dc converter with variable duty cycle..

so how can i implement it...
i am not much into this...

so basics will be very benificial...

thanx...

hey there seniors....

m preparing a solar tracking device that i have to finish within this week..
i have already completed the major portion...
plz see attachment...

bt i want to make two improvements...

1.)incorporate another two LDR's for season mounting...
2.)incorporate a dc to dc converter (variable duty cycle) for MPPT...

the circuit shows for a single motor...
kindly advice...
thanx....
