I think no need for WSP solutions, the SharePoint already handles this operation by adding the deleted site collection in the Second stage when a user accidentally deletes a site collection from GUI Central Admin.

How to Restore Deleted the Site Collection

If you've accidentally deleted a site collection, you can restore it back within 30 days depends on the Site Quota using Restore-SPDeletedSite PowerShell.

But if you need to keep the backup for a long time (> 30 days), you can handle this through the code, by developing your own Event Receiver to perform a backup when a site collection is being deleted

enter image description here

Now, you just need to know How to perform a backup to a site collection

Backup Site collection C# Code

SPFarm myFarm = SPFarm.Local;
SPServiceCollection myServices = myFarm.Services;
Guid serviceID = new Guid("21d91b29-5c5b-4893-9264-4e9c758618b4");
SPWebService webPubService = (SPWebService)myServices[serviceID];

// Get a reference to the Web application that hosts the 
// site collection.
SPWebApplicationCollection myApps = webPubService.WebApplications;
Guid appID = new Guid("10ea4e6f-ae37-4909-b04f-f516c066bc37");
SPWebApplication myApp = myApps[appID];

// As alternative to the preceding three lines, you can use
// the following when you know the URL of the Web application:
//     SPWebApplication myApp = SPWebApplication.Lookup(url_of_Web_app)

// Get a reference to the Web application's collection of 
// site collections. 
SPSiteCollection mySiteCols = myApp.Sites;

// Back up a specified site collection. 
mySiteCols.Backup(@"http://Server/sites/MySiteCollection", @"\\OtherServer\WSSBackups\SiteCollections\BackupOfMySiteCollection", true);
