Battery storage FAQs
How do home batteries work?
Your home battery or batteries will allow you to store the electricity your solar energy system produces during the day and use it when you need it most—such as in the evening during the time of use (TOU) peak pricing or when the electric grid fails due to an extreme weather event or physical damage to the equipment. (See below for more information on TOU peak pricing and whether it applies to your jurisdiction).
What are the benefits of home batteries?
A solar battery or batteries can help you maximize the value of solar energy, protect your home from power outages, and help build a sustainable future by supporting the production of renewable energy.
In California, local regulations allow you to do more with your battery. To optimize your system's overall value, we've programmed the battery to automatically help customers get the most out of their solar system by capturing their solar generated electricity and “shifting” it to when they need it most. This innovative solution optimizes potential savings by increasing self consumption during peak hours when rates are highest and reducing low-value exports back to the grid.
And with our expert solar installation, you can ensure that your home is equipped with the best battery system tailored to your energy needs.
Are there solar battery storage incentives available?
Many states and utility companies offer incentives, such as rebates or tax credits.
One such incentive is net metering, which credits any excess power your solar system generates back to your electric bill. However, several states have chosen to adopt Time-of-Use (TOU) rates, which complicate how your net metering credits are calculated. Sunrun Shift can buffer you from peak TOU rates so that you may save even more on your electric bill.
Will an energy storage system allow me to go off grid?
Our rechargeable solar battery systems are designed to keep you on the grid during normal service times while providing reliable backup when the sun isn’t shining or during an outage. This is the most reliable and economical way to use your home battery system.
How much storage does my home need?
Like solar-only systems, the size of your battery system will depend on your unique battery capacity needs. Factors such as the amount of electricity you use at home and the devices and appliances you want to back up will play a key role in selecting your ideal battery storage capacity.
Where will my home battery be placed?
Home battery is a relatively easy installation. Each battery is about size of a water heater, and the battery system is mounted on a wall—typically next to your electrical panel inside your garage or outside your home.
