PG&E manages the solar rebate program in Livermore, and it's unfortunately suspended at the moment. You can receive the most up-to-date information on PG&E's solar rebate program at this website.
While you might not be able to claim a rebate, consider that you'll still be able to access a 30% federal tax credit on the cost of your installation. Additionally, solar panel prices have come down a lot on their own, and a new system may not be as expensive as you imagine.
You might also want to ask about leasing or alternative financing options. Either way, installing a solar system in Livermore will save you a lot of money down the line. You can contact some solar installers in Livermore through our listing.
