IMPORTANT NOTICE

The Energy Commission is adding Inverter and Energy Storage Systems based Power Control System (PCS) data into our solar equipment lists. This PCS information will be detailed in a supplemental listing to our Inverter and Energy Storage Systems lists.

The PCS supplemental listing template, the listing request form and instructions are accessible from the Grid Support Inverters and from the Energy Storage Systems sections identified on our Solar Equipment Lists webpage.

Our solar equipment lists will be populated with the PCS data supplemental listing as we receive and process PCS data requests.

For additional information, please contact the Solar Equipment Call Center at (916) 654-4120, or SolarEquipment@energy.ca.gov

The Energy Commission's Solar Equipment Lists include PV modules, inverters (including smart inverters), meters, battery and energy storage systems, and related equipment. The Solar Equipment Lists are updated three times a month, typically on the 1st, 11th, and 21st of the month, or the first business day thereafter.

Forms and instructions on how to be listed can be found in the appropriate section below for each technology type (PV Modules, Grid Support Inverters, Batteries, Energy Storage Systems, Other Solar Generating Technologies, and Performance Monitoring Reporting Service Providers) .

Submitted information is reviewed by the California Energy Commission prior to equipment being added to the Energy Commission's Solar Equipment Lists, manufacturers’ self-reported information is not confirmed. Please note that equipment on the Energy Commission’s Solar Equipment Lists has reportedly undergone tests to achieve minimal safety and performance standards. The California Energy Commission makes no claim or warranty on the equipment and its safety, performance, or durability.

The CEC developed the Solar Equipment Lists under Senate Bill 1 (Murray, Chapter 132, Statutes of 2006), establishing criteria and standards for solar incentive programs under the California Solar Initiative, such as the New Solar Home Partnership Program (NSHP). The lists helped ensure the solar equipment met minimum safety and performance standards.

The purpose and use of the Solar Equipment Lists have expanded over time from initially supporting solar incentive programs. Information and data on these lists are used for purposes including researching, modeling, validating interconnection requirements by utilities, integrating smart inverters, and supporting other incentive programs.

The CEC supports the interconnection portion of Rule 21 by maintaining the Solar Equipment Lists and participating in Rule 21 working groups. Rule 21 is an electric tariff that describes the interconnection, operating and metering requirements for generation facilities to be connected to a utility’s distribution system.

The SB 1 guidelines established eligibility criteria, conditions for incentives, and rating standards for California solar energy system incentive programs overseen by the CEC, the California Public Utilities Commission (CPUC), and local publicly owned electric utilities (POUs).

Resolution Regarding Revisions to the Guidelines for California’s Solar Electric Incentive Programs (Senate Bill 1), 7th Edition - PDF
The resolution adopted at the July 15, 2019 CEC business meeting was effective immediately. It will be incorporated into the next revision of the SB 1 Guidelines.

Guidelines for California’s Solar Electric Incentive Programs (Senate Bill 1), 7th Edition - PDF
These guidelines are an available resource for learning about the requirements for the solar equipment lists.

The sections identified below by equipment type provide access to the current lists of equipment as well as request forms for new listing requests and instructions for submitting requests for equipment additions and revisions. 

List of PV Modules

There are two versions of the list of PV modules available for download - Simplified and Full Data. The Simplified version is intended to show only basic information about the PV modules such as manufacturer, model number, description, and PTC value. The Full Data version contains all the information in the Simplified version plus information such as reported nameplate ratings and temperature coefficients that may be of interest to stakeholders.

 Grid support inverters are inverters that include advanced functionality and communication abilities and are commonly known as “smart inverters”.  The Grid Support Inverter List includes information for solar and battery inverters.

List of Grid Support Inverters

There are two versions of the list of inverters available for download - Simplified and Full Data. The Simplified version is intended to show only basic information about the inverters such as manufacturer, model number, description, and weighted efficiency. The Full Data version contains additional information such as certification dates, reported nameplate ratings and efficiency measurements that may be of interest to stakeholders.

Inverter Manufacturer Attestation Form

To reflect the advanced inverter functions of Monitoring Data and Scheduling on the Solar Equipment Lists the manufacturer must provide a completed attestation. A copy of the attestation form can be found on the IOUs websites. All forms are identical.

Inverter Test Protocol

Utility interactive inverters are inverters that do not have advanced functionality or communication abilities and are commonly known as “non-smart inverters”.

The CEC no longer updates the non-smart inverter list. Data submitted to the CEC and approved for listing as of February 3, 2020, is provided in this list.

List of Utility Interactive (Non-Smart) Inverters

There are two versions of the list of inverters available for download - Simplified and Full Data. The Simplified version is intended to show only basic information about the inverters such as manufacturer, model number, description, and weighted efficiency. The Full Data version contains additional information such as certification dates, reported nameplate ratings and efficiency measurements that may be of interest to stakeholders.
