I am not totally certain why you should choose the middle of an array of solar panels to have a brawl, but if that's your intention - or you can come up with another need of a battlemap depicting this scene - well, here's a very nice one.
Depicted in Hollnbuchner's clean crisp style, the plan depicts serried ranks of solar panels between two dirt tracks. Viewed top-down, shadows are used to create depth for the panels. As the dirt tracks run through grass, this is suggested to be a rural area - solar power plants tend to need plenty of space after all - but temperate rather than desert.
Although it's pretty obvious what you need to do, assembly instructions are included. You will need to figure out a way to mark which solar panels get broken, assuming you are staging a combat scene here. Remember that some use quite nasty chemicals, as well as the more mundane problem of broken glass!
So if your intention is to disrupt power supplies, or you just happen to be mooching around a solar plant when your enemies catch up with you... or maybe something has been hidden out here that you want to find... here's the battlemap for you.
