//Using batch file to run the above script which we will name as InstallSite.ps1
Call it using batch file (.bat) which would contain follwoing code to run:

@echo off
@echo Creates and deploys Test.wsp
@echo args are folder path for solution file

C:\Windows\System32\WindowsPowerShell\v1.0\PowerShell.exe  " & ' C:\ Test \ Test \Deployment\Sites\InstallSite.ps1'

@Pause



Similarly the webparts can be deployed just we need to check the scope of the webpart. and deploying site section wont be included.
