battery charge arduino with solar panel and move motor servo

hi ..
I just finished with this project ..http://www.instructables.com/id/Self-Sufficient-Arduino-Board/?ALLSTEPS
but why when i loose the power of the computer and run my project, the servo motor does not move according to my previous projects?? http://www.instructables.com/id/Arduino-Solar-Tracker/
I combine these two projects into one project and run it ..
the question is
why the project is not going to use batteries??
I use ultra accuplus 9V battery or eveready 9V..
thanks in advance

I use ultra accuplus 9V battery or eveready 9V..

Smoke detector yes, servo no.
