"The desert has high albedo for the most part—sunlight bounces back from the light-colored soil and returns to outer space where it cannot warm the planet. Solar panels, on the other hand, are dark. The whole point of them is to absorb, not reflect, sunlight. They get hot. Hotter than the light sand that they are covering. Convection grows more powerful as hotter air rises with greater force. This changes the weather directly."
