not if your getting it anyway. if the cost is worthwhile for the cooling and defrost qualities anyway and you get some energy for free then even a little is fine. Its like the old prius that had solar panels to help with ac but it would not power the car.
Could be significant. The main reason I have to put on heat is to defrost and the rear window defrost is pants. then passive summer cooling could reduce ac quite a bit.
