How much will I save by installing a solar and/or battery storage system?

The Solar Cost Calculator Tool provides an estimate of savings you could realize by installing a rooftop solar system and compares your solar financing options side by side. Results are based on your rooftop characteristics, your electricity use, City of Palo Alto Utilities (CPAU) electricity rates, and available tax credits and rebates.

What other programs and rebates can help me save on my solar installation?

  • Free Energy Advice - When sizing your system, it's important to think about how your electricity needs may change over time. CPAU's Home Efficiency Genie offers free phone-based advice on topics that impact your electricity needs, like home efficiency upgrades, EV charging equipment and new technologies for space and water heating with high-efficiency electric appliances. Call the Genie at (650) 713-3411.
  • Federal Tax Credits - Take advantage of the 26% Federal Renewable Energy Tax Credit for solar and battery storage systems installed by December 31, 2022. The tax credit drops to 22% for systems installed during 2023 and expires for systems installed after December 31, 2023.
  • Heat Pump Water Heater Rebate – Pairing an electric heat pump water heater (HPWH) with solar could reduce the cost of running the HPWH, compared to running it without solar. Apply online for a heat pump water heater rebate of up to $1,500.
  • Energy and Water Rebates  CPAU energy and water Programs and Rebates can help you save money and increase the comfort of your home.

How can I further reduce my home’s greenhouse gas emissions?

CPAU encourages customers to consider electrification, a shift from fossil fuels to electricity for space and water heating, transportation, cooking and clothes drying. CPAU's electricity is sourced from renewable and hydroelectric resources, but natural gas is a fossil fuel that is a potent greenhouse gas itself and that also produces greenhouse gas emissions when burned. In Palo Alto, an all-electric lifestyle is cleaner and healthier than using fossil fuels.
