"Albedo" may be a part of the solution : find something clear that reflect the sun and cover the ground around the panels. Not only the panels will receive more indirect light, but the surrounding will be more cool and the panels less hot.
Hope I'll be able to take picture of what we installed lately to shade the office bay and the kitchen window. Not only they permit the office and the kitchen to not be hot, but the ground is more cool so the air at the base of the panels. I have only the feeling that it helps a little in my case, but I'm working on trying to find the way to show it without having to remove the shades.
Ventilation is also important. This is noticeably important for roof integration as I have and as it's privileged in France by better buying rates. Finding a more ventilated place could be a solution.
Water is certainly bad as it will make things to depose on the panels and will not remove so much heat. A way to remove more heat with water would be to mist it (make very small drops that instantaneously evaporate and absorb "a lot of" heat).
At least don't put them under some trees as I have seen it in a US TV series lately
