Hello today we will write the powershell script to install the wsp to the sharepoint solution store.

1. Open any text editor.

2. Copy the below lines of script code inside it and save the file as like "Install.ps1".

3. You need to change the current directory path of the wsp inside the script .For that find the "$CurrentDir" and replace it with your existing wsp path.
i.e. if you existing wsp is located to "D:\Solution Package" then value of the $CurrentDir is
$CurrentDir="D:\Solution Package"

4. Once the solution path will modified then change name of your wsp package.For that find the $solutionNameCollection value and replace it with your existing wsp name.
   i.e.if your wsp name is like "Sharepointcustom.wsp" then the value of $solutionNameCollection is
   $solutionNameCollection = @("Sharepointcustom.wsp")
   Note: if tou want to install the multiple wsp to the sharepoint solution store then seperate the wsp with comaa(,)
i.e. $solutionNameCollection = @("Sharepointcustom1.wsp","Sharepointcustom2.wsp","Sharepointcustom3.wsp")

5. Now the time is to change your sharepoint WebApplication url on which you want to install the wsp.For that
   find the $SiteUrl and replace its value with your webapplication url.
   $SiteUrl="http://server:port"
 
6. Install-SPSolution –Identity $solutionName -WebApplication $SiteUrl –GACDeployment -Force:$true
   This line will deploy the wsp on specific web application.If you want to deploy the wsp Globally then folowing command will use.
   Install-SPSolution –Identity $solutionName –GACDeployment -Force:$true

7. Save all the changes and open the "SharePoint Management Shell"  as an administrator mode from
   All Program -> Microsoft Sharepoint 2010 Products -> SharePoint Management Shell
 
8. Change the direcory path with the existing wsp path that you have already set the value of $CurrentDir="D:\Solution Package" in the script.
   From the powershell command propmt type the following command and press enter.
   cd "D:\Solution Package"
 
9. Now type the following command and press enter.
   .\Install.ps1
 
10.Likewise powershell script is used to install the single or multiple wsp packages to the sharepoint solution store
