Solar panels are vastly more effective than a shade tree for keeping a home cool.
The geometry of trees and solar panels changes with latitude, but in California you can still have tall trees fairly close to your house while using solar panels. Further, roof panels can also shade your roof though with proper insulation that should not be significant.
