"If you cover the roof with panels you will be making your own shade."
Provided the panels are well above the roof and well ventilated. Otherwise it would be much like the heat build up that occurs in an attic. Just running an attic fan, and no a/c, can lower house temperature significantly.
I'm looking into actually harvesting this solar heat for winter under-floor hydronic heating. There are solar panels available with built in heat exchangers/collectors. In summer, the heat would be exhausted to the outdoors using a fan/heater core combination.
