Download Current CSI Data

All data found on the California Solar Statistics site is exported from the CSI incentive application database and made available to the general public through the "Download Filtered Data" links on each figure, as well as through the complete files found on this page. The data is exported each Wednesday evening, and represents the most current and complete California Solar Initiative data available.

Attention Users: Please be aware that starting on August 27th the California Center for Sustainable Energy's (CCSE) recent name change to the Center for Sustainable Energy (CSE) will be reflected in the CSI Working Data Set in the “Agency” field and throughout California Solar Statistics.

Working Data Set

The Working Data Set is the file from which all figures and tables found on California Solar Statistics are generated. A broad set of data tests are applied to the Raw Data Set to remove applications with critical data errors which may compromise the data presented on this site. Typically, less than 0.01% of applications are excluded by these tests. View Excluded Applications.

PLEASE NOTE: If you are using an older version of Excel (2003 or earlier), you will be unable to view all of the data in this file. If you are experiencing this problem, please contact csisupport@energy-solution.com for assistance.


You can also download the current Raw Data Set here. This set represents the data exactly as it exists in the database, including any applications that have been removed from the Working Data Set due to erroneous data. For more information about the difference between the Raw Data Set and the Working Data Set, please go here.

For previous versions of the Raw Data Set, please view the Data Archive.

For data regarding solar projects which were incentivized before 2007 (Pre-CSI) please go here.

Projects that receive Performance-Based Incentives (PBI) also provide monthly system production data, which can be found in the Measured Production Data Set below.
