Consider building a base upon which this can sit so you don't have to stoop too much. Also recommend a solid floor, wood or bricks work. This plus the base, then anchor your kit to it. The lifespan of polycarbonate panels is 5-10 years, and you can reach the upper limit of that if they aren't blowing out all the time; this is nothing that can't be resolved by a generous bead of silicone sealant in the channel you slid them in to.

Edit: to add, I love it and gardening and I'm happy for you. Good luck and bountiful harvests.
