Is battery storage right for you?

Battery storage is a way to have additional control over powering your home. PG&E is here to provide helpful information on whether battery storage is right for you, answer your questions and help you understand the steps to get started.

Understand if battery storage could benefit your home

Battery storage today is not about savings, but you may be considering it for peace of mind. Batteries have the most benefit if you have solar, are on a PG&E time-of-use rate or electric vehicle rate, or if you need continuous power for certain appliances or medical devices. The majority of residential customers today won’t see bill savings from storage, but as battery prices come down over the next few years, storage will help more customers save money.

  • Potentially maximize your solar investment: If you have solar photovoltaic (PV), having a battery can help optimize carbon reduction impacts and energy bill savings.
  • Potentially reduce your energy costs: If you are on a time-of use-rate or an electric vehicle rate, your battery can charge when energy is cheaper (for example at night) and discharge energy when energy is more expensive. PLEASE NOTE: Given the large initial investment in a battery, it is not likely that this method will save you money over the long-run.

  • Backup power: For solar customers, the grid acts as a battery under the Net Energy Metering program. If you feel you lose power multiple times per year, a battery storage system is capable of providing emergency power to an individual’s home for several hours. PLEASE NOTE: Incentives are not available for backup-only purposes.

Battery technology performs two main functions:

  • Charging: from either your private rooftop solar system or from the PG&E grid to be stored and used at a later time.
  • Discharging: using the energy stored by the battery to either power your home or return back to the PG&E grid.

Rooftop solar panels on your home feed your storage batteries. The batteries then send power back to your home or to the PG&E grid.Opens in new Window.
  • Smart Management Software: This software is included with every battery to automate the charging and discharging process and monitor system performance to help product safety and reliability. Smart home apps are available for many batteries help customers monitor energy. The software can be programmed to automatically charge the battery when energy is cheaper and discharge when it’s more expensive.
  • Inverter: Inverters are necessary to convert stored energy from your battery to your home or back to the PG&E grid. Inverter installation will be included when the battery is installed by your contractor.
  • Battery Maintenance Energy: Batteries use a small amount of energy to stay in an operational state whether or not they are being discharged. This may have a small impact on your monthly energy usage and bill.
