| Starting in 2023, capacity and customers are now collected for batteries. Prior to 2023, the battery historical data was listed as storage. N/A = Not Available. Total customer count for the years 2007, 2009, and 2010 were revised based on requests from respondents. Capacity and customer count was not collected by technology type before 2010. Starting in 2013, there is no maximum capacity on installed units. Starting in 2016, utilities have the option to report photovoltaic in DC or AC. Values have been converted to AC.
