California Solar & Storage Association (CALSSA) Annual Solar Data Shows Record Year in 2022

Complete interconnection data for 2022 has just been released. It shows that California customers installed more solar and storage last year than ever before. CALSSA has prepared data analysis on market totals and the market leaders.
The total for behind-the-meter solar was 2080 MW, including 1716 MW for residential customers and 364 MW for commercial, industrial, and agricultural customers. This was a small step backward for commercial solar statewide but a big step forward for residential solar. Together it is a 75% increase over the 2016-2020 average.
The tally by number of systems is equally impressive. More than a quarter million customers installed solar in 2022. That is the equivalent of a system every two minutes, around the clock for the entire year.
California customers installed 262 MW of energy storage, nearly the same amount as the previous year. The commercial market increased 43% to 48 MW, while the residential market shrank 9% to 215 MW. We installed batteries for 36,000 customers. These numbers are for final interconnection, so they do not reflect commercial projects that are recently contracted with long development cycles.
Cumulative installations of behind-the-meter energy storage installations have surpassed 1 GW, and are increasing by 22 MW every month. A total of 2400 contractors installed at least one solar system last year, and 920 contractors installed at least one storage system. 197 contractors installed more than 1 MW of residential solar systems, and 72 contractors installed more than 1 MW of commercial solar.
