How to Deploy Multiple WSP Solutions using PowerShell in SharePoint?

Requirement: Have a bunch of WSP solution packages and had to add and deploy all of them to a cloned SharePoint environment.

Solution: Lets bulk deploy all WSP solutions from a folder to SharePoint using PowerShell.

PowerShell script to bulk add Multiple solutions:

Add-PSSnapin Microsoft.SharePoint.PowerShell -erroraction SilentlyContinue

Function WaitForInsallation([string] $SolutionName)
        Write-Host -NoNewline "Waiting for deployment job to complete" $SolutionName "."
        $WSPSol = Get-SPSolution $SolutionName
            sleep 2
            Write-Host -NoNewline "."
            $wspSol = Get-SPSolution $SolutionName
        Write-Host "job Completed" -ForegroundColor green

Function Deploy-SPSolution ($WSPFolderPath)
    #Get all wsp files from the given folder
    $WSPFiles = Get-childitem $WspFolderPath | where {$_.Name -like "*.wsp"}

    #Iterate through each wsp and Add in to the solution store
    ForEach($File in $wspFiles)
        $wsp = Get-SPSolution | Where {$_.Name -eq $File.Name}

        if($wsp -eq $null)
            write-host "Adding WSP solution:"$File.Name
            Add-SPSolution -LiteralPath ($WspFolderPath + "\" + $file.Name)
            write-host "solution already exists!"


        Deploy-SPSolution "C:\WSPFiles"
    write-host $_.exception

Once added to the SharePoint solution store, You can either deploy them to the targeted web applications/globally using PowerShell,

Install-SPSolution -Identity "Solution-Name" -Webapplication "Web-App-URL" -GacDeployment -Force

or use the below code to deploy all solutions in one go:

#Deploy all installed solutions in the farm
Get-SPSolution | ForEach-Object { if (!$_.Deployed) {
 If ($_.ContainsWebApplicationResource -eq $False) {
    Install-SPSolution -Identity $_ -GACDeployment 
else {
    Install-SPSolution -Identity $_ -AllWebApplications -GACDeployment 

Deploy SharePoint Solution Manually:

You can deploy from the SharePoint Central Administration site manually.

  • Navigate to SharePoint 2013/2016 Central Administration site.
  • Click on System Settings >> Manage Farm Solutions under Farm Management
  • Pick the relevant solution from the solution store
  • Click on “Deploy Solution” to start deploying the solution.
    sharepoint powershell deploy multiple solutions
    You may also have to activate necessary features that came through deployed solutions!

    This solution does not overwrite and update existing WSPs on sharepoint farm. Only non existing solutions will be deployed. For me, this did’nt help.
