Rooftop solar system median size up 200%, with storage pairings rising: DOE lab

In 2022, around 10% of all new residential solar installations included paired storage — up from virtually zero in 2015.

Across the U.S. market, California “dominates” in sheer numbers of residential solar installations, according to LBNL. And 11% of those systems have attached storage, a trend Barbose said is driven in part by rebates for storage and by the California Public Utilities Commission’s Self-Generation Incentive Program.

However, system sizes in California only average 7.1 kW – “near the low end of the spectrum,” LBNL said, which pulls the U.S. median downward. While median system sizes in most states are “well above 8 kW, and in many states above 9 kW,” California’s overall share of the market means national median size is 7.2kW.
