AeroStealth lives north of Las Cruces, and he always observes reduced output from his PV array because of summer temps.
A neighbor where I live had a solar-tracker mount for his PVs, which had two degrees of freedom, vertical and horizontal. as it followed from sunrise to sunset. Same deal with summer performance.
Mine were fixed at 33-degrees for my latitude, at true-south, and also fell off in the summer.
