I am also currently a CA resident, planning to move as soon as the house is finished. I am installing solar water heating in the HI house. The project qualifies for both Federal and Hawaii tax CREDITS. NOT a rebate, but you can apply the credits respectively to any Federal and Hawaii taxes owed, and can carry forward any excess credit until you use it up.
Hope this helps.
