Deploying Site Scoped solutions Farm wide (All Site Collections)

Question

Is it possible to deploy & activate a site scoped wsp to every site collection in a Farm?

I have a VS solution scoped to Site. It creates a pre-populated Choice column. I can build the wsp, Add-Solution via PS, Install-SPSolution via PS.

But it only appears on the Central Admin Site Collection features. I need the feature to be installed & activated on every site collection in the farm and across multiple Web Apps.

try the below script, you have to replace the web application url and feature name below.

Add-PSSnapin microsoft.sharepoint.powershell -ErrorAction SilentlyContinue
 $webs =  get-spsite -webapplication "http://www.yoursharepointURL.com"
 $feature = "YourFeatureName" #this might not be what you expect it to be, best to do get-spfeature | Select displayname

  Foreach ($oneweb in $webs)
  {
    write-host $oneweb
    $siteFeature = get-spfeature -site $oneweb | Where {$_.displayname -eq $feature}
    if ($siteFeature -eq $null)
    {
      Write-Host "Activating Site level Features at $oneweb" -foregroundcolor Yellow
      Enable-SPFeature -Identity $Feature -URL $oneweb.URL -Confirm:$False
    }
    else
    {
      Write-Host "Feature $feature is already activated on $oneweb" -foregroundcolor green
    }
  }
