As part of the June 23, 2010, business meeting, the Energy Commission will consider adopting revisions to the Guidelines for California's Solar Electric Incentive Programs (Senate Bill 1), Second Edition. These guidelines establish eligibility criteria, conditions for incentives, and equipment rating standards for all ratepayer-funded solar electric programs in California.

At the direction of the Energy Commission's Renewables Committee, proposed changes, of limited scope, have been made to the guidelines to clarify eligibility criteria, conditions for incentives, and equipment rating standards for all ratepayer-funded solar electric programs in California.

The proposed changes to the Guidelines for California's Solar Electric Incentive Programs (Senate Bill 1), Second Edition are:

  • Change of the effective date to July 1, 2011, by when all eligible inverter-integrated meters shall be tested to ± 5 percent accuracy by a Nationally Recognized Test Laboratory in accordance with the "Inverter Integral 5% Meter Performance Specification and Test Requirements" adopted by the California Public Utilities Commission.
  • Revision of the effective date stated in the guidelines for the 2008 Building Energy Efficiency Standards to be consistent with the Commission's separate decision to revise that date to January 1, 2010.
  • Clarification of photovoltaic module eligibility requirements including: requiring photovoltaic modules with different power ratings to have unique model numbers for incentive purposes, updating references to current versions of International Electrotechnical Commission (IEC) Standards 61215 and 61646, and inclusion of optional submission of data for additional performance parameters.
  • Clarification of the use of the Shade Impact Factor when accounting for shading using Monthly Solar Availability. The proposed clarifications modify the guidelines to indicate that the calculations using the Shade Impact Factor belong in the incentive calculation, not in the output data from a solar assessment tool.
  • Modification of the Installer System Inspection alternate field verification protocol for multi-string arrays so that photovoltaic system tests and measurements may be performed simpler and potentially safer.
  • Minor grammatical and editorial changes.

The Energy Commission Renewables Committee is publishing the proposed guideline revisions (Publication No. CEC-300-2010-004-CTF) for public review. They are available online at The Energy Commission is addressing only these changes at this time but is planning a workshop for later this year to discuss additional changes to the guidelines.

Note that the Solar Offset Program is a separate proceeding (Docket# 09-SOPR-1). The purpose of the Solar Offset Program is to develop regulations governing the requirements for alternatives to offering solar energy systems as an option for new production homes, as required by Public Resources Code 25405.5 (c).
