A portion of that is items that previously weren't on the military line, but now are. Take your solar example. That has nothing to do with the military (or military readiness, in particular), but it is bought with a military colored dime.
As to your mention of $1000 toilet seats, those things do happen. They are a result of all of the political rules attached to acquisition.
There is no doubt that true military readiness could be had for much less that we spend today. However, the services have little control over the processes that could truly slash the budget while maintaining readiness.
