Solar powered motor and timer
                                    Hi,
I am new to this site so please bare with me. 
I am working on a project where I need a way of powering a 7v 165mA water pump for 5 minutes every 3 days. 
I have been using a small solar panel and manually connecting it when I need to run the motor. Now I would like to automate it and introduce a battery and timer circuit in order to completely automate it. 
Any advice on what I would need to build this or on where I may be able to get one made would be greatly received. 
Thanks in advance
