This is basically baking your plant if it's getting light/heat from the sun and then reflected back upon form those 2 fences.
If you can't or don't want to move the plant I woudl suggest getting some shade clothe and hanging it on the fence to dampen the heat and light.
I've had to do this myself as this was killing both Banana plants and tomato plants in my grow area.
