“It appears that ENPH and SEDG each comprise market share in the mid-teens vs. TSLA in the low- to-mid 40% range,” they explained. “The data would suggest that TSLA is the preferred battery for backup, as it has the highest average kWh installed while ENPH and SEDG only have 7-10% of their installations with more than 10 kWh.”
Meanwhile, battery attach rates continue to climb, with Sunrun (NASDAQ:RUN) leading. While it is even higher than TSLA, it has the lowest average kWh per installation, according to Barclays.
“According to the December data, RUN’s attach rate is at 74%, the highest in the group, with NOVA as the laggard of the group at ~60%,” analysts explained. “However, it does appear that RUN has the lowest kWh, which likely reflects its marketing of Shift at the start of NEM 3.0, its load-shifting product while the other Tier 1 installers don’t really have a similar product.”
