Not to nitpick here...

Upgrading your service from 100A to 200A will get you only 22kW of total new power, or 17.6kW usable.  Just want to make sure you understand that you're not going to have 24kW available for use out in those sheds, unless of course you don't mind tapping into the original 100A you had in your home already.  You'll need just about 136A out to those sheds to get 24kW of usable power.... this is all assuming you've got 220V service.
