Folding solar panel stand

For camping I need a stand for the panels thats easy to fold away and set up again. I intend to take all three 18w panels next time I go so I need a stand to hold them when they're in use. I came up with this idea with a little help from my Grandad who suggested the tent peg feet feature (thanks Grandad!).

Its a simple 'A' frame design which will be made easy to take apart, fold up and fit in the boot of the car. The cost will be minimal since its only a few pieces of wood, string and bolts. All-in-all, it should be up for the job!
