Air conditioners don't need to use fossil fuels. Solar power and AC work really well together because peak solar energy is exactly when you need AC the most.
No heat is created either, that would explicitly violate the first law of thermodynamics. An air conditioner powered by solar energy (or anything solar powered) ends up releasing the exact same amount of "excess" heat as the sunlight would have if it hadn't been absorbed by the panels.
