If you go to the websites of the various fabric manufacturer's, you'll find their free patterns featuring their fabrics. You may not have the same fabrics/panels they've used, but their patterns will give you ideas of things you can do with your panel.
For example, this morning I was looking at this site for ideas and found several cute ones...
I also love the Clever Quilts books by Susan Teegarden Dissmore and have made quilts using panels and her ideas.
Dot Collins has a pattern for a "Tossed Salad" quilt which uses panels with pieced blocks. I bought my pattern at a guild meeting recently...Dot will be coming here to do a workshop on it next month. Here's what it looks like...
It reminds me of the designs in Susan Dissmore's Clever Quilts books.
I also get ideas from the LQS which generally has some darling quilt tops on display that they've made using panels.
I love panels, but I find them much more challenging to use than a lot of traditional patterns. I'm always triple-checking my math to make sure the panels and blocks are going to fit together properly .
Good luck with your endeavor!
