Solar and battery storage firm Sunrun Inc. is experiencing a rise in battery sales in the US, notably in California, the country’s largest solar market. This surge follows California’s reduction of rooftop subsidies, aimed at promoting backup power as the sun sets.
In the fourth quarter, Sunrun reported that about 45% of its new US sales included both solar and storage, a significant increase from 33% in the previous quarter and 15% at the start of last year.
Approximately 85% of new sales in California involved solar and storage systems over the previous two quarters of 2023, compared to only 20% before the state’s rooftop incentive policy change.
“We’ve moved to a solar-plus-storage company,” Chief Executive Officer Mary Powell said on an investor call Wednesday with Bloomberg.
Powell added that the California solar market is growing faster than the rest of the country for Sunrun due mainly to the company’s increased focus on batteries.
“We called 2023 the year of storage, and we were leading with storage.”
