Data Downloads

California Solar Statistics publishes all IOU solar PV net energy metering (NEM) interconnection data per CPUC Decision (D.)14-11-001, and all IOU data from the California Solar Initiative incentive program per California Senate Bill 1 (SB-1).

Currently Interconnected Data Set

The Currently Interconnected Data Set provides a full view of all interconnected solar PV (NEM) systems within PG&E, SCE, and SDG&E service territories. This dataset contains all interconnected (excluding pending and decommissioned) projects with one row per interconnection address/project site. It is updated monthly.

Interconnection Applications Data Set

The Interconnection Applications Data Set contains all interconnection applications including those that are pending or decommissioned. When a project is modified a new interconnection application must be submitted to the IOUs, which means some projects will have multiple interconnection applications.

California Solar Initiative Data

All charts and tables found on the California Solar Statistics site are created 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.

CSI Working Data Set

All figures and tables found on California Solar Statistics are generated from the CSI Working Data Set. 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.

CSI Raw Data

This set represents CSI data exactly as it exists in the database, including any applications that have been removed from the Working Data Set due to erroneous data. Please see the FAQ for more information about the differences between the CSI Working Data Set and CSI Raw Data.

CSI Measured Production Data Set

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