What solar system performance data information is needed?
The CPUC's CSI evaluation program needs solar system performance data for systems that were operating anytime between 2007 through the end of 2009. Performance data being sought is the 15-minute electric net generation interval data from any grid-connected solar project that is installed in the territories of PG&E, SCE, and/or SDG&E. For your convenience, the performance data can be in any delimited electronic data format and should contain:

• Site identification including Incentive (CSI, SGIP, ERP, etc.) Application Number, Installer, host or site customer name, site address, and utility account information. The most valuable of these is the Incentive Application Number if it is available (it provides a robust link to other needed site data);
• Time and date for each interval and an indication if this time is the beginning or end of the data collection period; and
• Energy or power generated during each time interval and indication if this data is kW, kWh, etc.

You may submit your production data in any file format (excel, word, pdf, etc.) using the submission form here:
