How to to deploy Solution file (WSP) from Central Administration:

        1- Open you power shell using administrator id (run as administrator).

        2- Add WSP to your farm using the following command:
       stsadm -o addsolution -filename

       Ie:

2-   From 'Central Administration', go to 'System Settings' > 'Manage Farm Solutions'

3-  Select your WSP file to deploy

4-  Click 'Deploy Solution'

5-  Configure your Deployment Settings.
