CSLB Disclosure Documents
Solar customers must be provided with these disclosure documents before a contract is signed.
CSLB Disclosure Documents
The Solar Energy System Disclosure Documents from the Contractors State License Board (CSLB) contain key financial information and rights regarding a solar customer’s contract. This includes the total cost of the system, a one-year bill savings estimate, and the three-day right to cancel (five if the customer is over 65 years old). The two Disclosure Documents that customers must receive are:
Both above documents, or their respective accepted versions, must be submitted to a utility for a solar interconnection application to be considered complete. Other acceptable versions of these documents, including documents for contracts with a five-day right to cancel and versions in Spanish, are available on the CSLB’s website. Contractors should not modify the PDF fields of these documents.

Regulatory Overview
Assembly Bill (AB) 1070 (2017, Gonzalez Fletcher) required the Contractors State License Board, in collaboration with the California Public Utilities Commission (CPUC), to develop solar energy system disclosure documents to provide customers with clear and accurate information regarding the installation of their solar systems, including but not limited to financial details of the installation.
The single-page “cover page” of the disclosure document has been in effect since January 1, 2019. The longer Solar Energy System Supporting Information document has been in effect since November 1, 2025.
Energy Division issued an updated version of the Solar Energy System Supporting Information document on July 28, 2025 (version 2). Version 2 of this document must be the version submitted in interconnection applications.

FAQs - Solar Energy System Supporting Information form
Yes, both the cover sheet and the Solar Energy System Supporting Information (SESSI) documents are required to be filled out and given to the customer. Both forms must be uploaded to your utility’s interconnection portal for the project’s interconnection application to be considered complete.
If you are unsure whether a subcontractor will be used at the time the SESSI form is given to the customer and/or uploaded to your utility’s interconnection application, respond with the most likely situation. If your project takes on a new subcontractor after the form is already given out, update your customer with the name, license information, and contact information for the subcontractor.
Fill out the number of full years of the term of the financial product in the “years” section, and include any extra months in the “months” section. For example, if a loan term is exactly 20 years, fill in “20” in the years box and “0” in the months box, or leave the latter blank. A loan term of 20.5 years should be filled in with “20” in the years box and “6” in the months box.
If a customer is using cash and a loan to finance their system, then the total cost box should reflect the cash and loan payments combined. The monthly payment box should reflect what the customer should expect to pay each month. The interest rate box should be filled in as well.
There may be other types of financing that do not neatly fit into the given fields on the SESSI form. In these situations, it is the responsibility of the contractor to represent the financial responsibilities the customer will face as accurately as possible given the existing boxes, and communicate these to the customer. Make sure your customer knows exactly how much they are paying for their solar and/or storage system and how much they should expect to pay in the future.
The Disclosure Documents are not required if a battery storage system is not being connected to an existing or new renewable energy generation system (solar or otherwise).
Resolution 5364 requires the SESSI form to be typewritten. If your form is handwritten, you may be subject to penalties and placed on the CPUC’s Public Watch List of Non-Compliant Solar Providers.
