In April 2024, more than 50% of residential solar photovoltaic installations were paired with battery storage, compared with just over 20% in October 2023. The shift toward more battery storage at solar installations eligible for net metering came after changes to California's compensation structure.
During sunny days, your solar panels often generate more electricity than your home consumes. Without a battery, this excess energy typically flows back to the electrical grid. With a solar energy storage system, you can capture and store this surplus energy for use during evenings, cloudy days, or power outages.
Strong growth occurred for utility-scale battery projects, behind-the-meter batteries, mini-grids and solar home systems for electricity access, adding a total of 42 GW of battery storage capacity globally.
The share of new residential solar photovoltaic systems paired with batteries has increased since we began collecting data in October 2023. In April 2024, more than 50% of residential solar photovoltaic installations were paired with battery storage, compared with just over 20% in October 2023.
