It could be a fancy cover on a sliding track or as simple as a heavy tarp that you tie over it, but an overhang is going to give you good passive shading.
Most people however install a dump loop of some sort so they can dump the extra heat in to the ground, doing this still allows you to use you to get solar heated water in the summer without worrying about over heating your system, if you have a pool or a hot tub then they would be the perfect heat dump, otherwise just a loop of pex dug in to the back yard works really well.
