The purpose of the workshop is to present a summary of proposed changes to the adopted SB 1 Guidelines and to solicit comments from interested parties. The document, Draft Guidelines for California's Solar Electric Incentive Programs Pursuant to Senate Bill 1, Second Edition, publication # CEC-300-2008-007-D, contains the proposed modifications and the Acrobat PDF file can be downloaded from the Energy Commission website at: [/ (PDF file, 104 pages, 1.4 MB)].

The Energy Commission document, Guidelines for California's Solar Electric Incentive Programs Pursuant to Senate Bill 1, established eligibility criteria, conditions for incentives, and equipment rating standards for all ratepayer-funded solar energy system programs in California. The guidelines established minimum program requirements to be met by January 1, 2008 and allowed for a transition period for full compliance by January 1, 2009. Publicly owned utilities with peak demand of 200 megawatts or less (as reported for calendar year 2006) may delay implementation of requirements in Chapters 4 and 5 no later than January 1, 2010.

Please note that the workshop was originally scheduled to be held on Monday, September 8, 2008, and is now re-scheduled for Monday, September 29, 2008.

Summary of Proposed Changes


  1. (Chapter 1) Add audit requirement that will facilitate the Energy Commission to conduct random audit annually to evaluate operational performance of systems so that utilities are informed.

  2. Extend implementation date from January 1, 2009, to July 1, 2009, for Chapters 3, 4, and 5.

  3. (Chapter 2) Address other covered solar electric generating systems under Solar Energy System Definition and Solar Energy System Components.

  4. (Chapter 3) Eligibility requirements for other Solar Electric Generating Systems Component.

    These technologies are proposed to be listed as eligible for Performance Based Incentives only, with a requirement for safety certification testing from a Nationally Recognized Testing Laboratory.

  5. (Chapter 4 and Appendix 2) Shading and incentive calculation tolerance. Address shading estimation and methodology for retrofit and larger commercial scale systems. Allow Program Administrators or utilities up to 5 percent tolerance related to incentive calculation, claim and field verification.

  6. (Chapter 4 and Appendix 2) Field verification requirement for PV installers.

    Offer program administrators the option to exempt the PV installers under their program implementation from performing the detailed field verification protocol and follow the alternate protocol for installers or perform 100 percent field verification. Require some PBI systems to be field verified.

  7. (Chapter 5) Update the newly constructed buildings' energy efficiency requirements by defining the Tier I and II levels to reflect the adopted 2008 Title 24 (Part 6) Building Energy Efficiency Standards which will take effect July 1, 2009 onwards.

  8. (Chapter 5) Remove the benchmarking exemption for Performance Based Incentive applications.


  1. (Chapter 1) Clarify schedule.

    Chapter 6 should not be included in the January 1, 2008 requirement and only applies to publicly owned utilities.

  2. (Chapter 2) Clarify system warranty.

    The ten-year warranty requirement is optional for stand-alone performance meters and program administrators have discretion over how the 10-year warranty provisions would be applied under their respective solar programs.

  3. (Chapter 3 and Appendix 1) Adopt the 5 percent inverter-integrated meter testing protocol for performance meters developed by the California Solar Initiative metering working group to be implemented by January 1, 2010.

  4. (Chapter 5) Clarify language under Alternative Portfolio Energy Savings.

  5. (Chapter 6) Modifications beginning in 2009 reporting requirements and forward: clarify that rejections include cancellations under number of submitted applications, clarify public goods charge funds as solar funds, itemize solar incentive expenditures by category, provide breakdown of installed systems for Tier I and II levels for new construction buildings, modify amount of added solar capacity and expected generation for all solar energy systems and provide description of other solar electric generating systems deployed, remove goals for each reporting period in terms of capacity (kilowatt), and remove solar energy system and energy efficiency implementation impacts. Only require submission of report electronically.


Senate Bill 1 (Murray, Statutes of 2006, Chapter 132) requires the Energy Commission to establish eligibility criteria, conditions for incentives and equipment rating standards for all ratepayer funded solar energy system programs in California, pursuant to Public Resources Code Section 25782. These ratepayer funded programs include those implemented by the California Public Utilities Commission (CPUC) and by local publicly owned electric utilities pursuant to Public Utilities Code Sections 2851 and 387.5, respectively. Senate Bill 1 identifies the following conditions for receiving ratepayer funded incentives under the law: 1) high quality solar energy systems with maximum system performance to promote the highest energy production per ratepayer dollar, 2) optimal system performance during periods of peak demand, and 3) appropriate energy efficiency improvements in the new and existing home or commercial structure where the solar energy system is installed.

Two Committee workshops were held on August 22, 2007, and October 4, 2007, to solicit comments on the staff report, publication # CEC-400-2007-014 and the draft Guidelines, publication # CEC-300-2007-012-D, respectively. As a result of these workshops, staff issued the final Guidelines, publication # CEC-300-2007-012-CMF, and the document was adopted at the Energy Commission's Business Meeting on December 19, 2007. The document is organized into sections addressing Senate Bill 1 mandates for solar energy component standards, solar energy system installation standards, energy efficiency, reporting requirements, effective dates, and other eligibility criteria established in statute.
