The California Solar & Storage Association works to uphold the highest industry standards by promoting best practices and protecting consumers.

All members must comply with our Code of Ethics as well as our NEW Consumer Protection Rules to be considered in good standing. An Ethics Committee investigates complaints from customers and engages the appropriate state authorities when necessary.

Our Code of Ethics

NEW! Consumer Protection Rules

INTRODUCTION: These rules, and the principles on which they are based, do not constitute legal advice.  Each Member should consult its own counsel in connection with the items mentioned below.  Where rules reference compliance with existing law, they do so for educational purposes and to bring heightened awareness to members.  These rules are mandatory and apply directly to Members. CALSSA recognizes that Members hire subcontractors and vendors to provide goods and services for their projects and their business (“Vendors”).  Members shall be held accountable for any violation of these Consumer Protection Rules.

General Rules

All CALSSA Members Must:

  1. Meet all applicable licensing and registration requirements, such as

    1. Home Improvement Salesperson (“HIS”) registration with the California Contractors State License Board (“CSLB”);

    2. CSLB licenses in the appropriate classification for the work performed; and

    3. Lender license requirements, as applicable.

  2. Respect consumer privacy, including complying with all applicable privacy, telemarketing, door-to-door sales, and email solicitation laws and regulations.

  3. Consider a consumer’s mental capacity and ability to understand the terms of a contract and adjust their approach in response to that capacity.

  4. Not mislead or deceive consumers (directly or by omission). Special attention must be paid to material aspects of a solar offering, such as

    1. Pricing;

    2. Performance;

    3. Warranties; and

    4. Company affiliation or endorsements.

Lead Generation Consumer Protection Rules

NOTE: While CALSSA cannot address every claim or circumstance that may arise, the following rules are based on the above “General Rules” and provide guidance on specific topics.  These rules should be interpreted broadly to fulfill the intent of their consumer protection focus, the Code of Ethics, and the General Rules stated above. 

At a minimum, Members shall take reasonable steps to oversee lead generation Vendors who have contact with consumers, including by:

  1. Verifying that the Vendor understands and is capable of complying with relevant laws as well as the CALSSA Code of Ethics and these Lead Generation Consumer Protection Rules (“Consumer Protection Rules”).

  2. Requesting and reviewing the Vendor’s policies and procedures and training materials and identifying any inconsistency with these Consumer Protection Rules.

  3. Including clear expectations in its Vendor contracts regarding compliance with applicable law and these Consumer Protection Rules.

    2. Allow the Member to withhold compensation or terminate any Vendor who is discovered making unsolicited telemarketing calls in violation of the TCPA.

    3. Allow the Member to require any Vendor who is the source of ten or more complaints made to the Member within one month to retain, at the Vendor’s expense, a reputable, third-party to audit the Vendor’s practices.

    4. Require the Vendor to identify itself by name on all telemarketing calls it refers to the Member and otherwise refrain from attempting to mislead consumers about the origin or nature of the call.

    5. Require the Vendor to comply with rules governing registration of fictitious names.

  5. At least twice each calendar year, Members shall conduct a random audit of all their telemarketing Vendors to confirm the Vendor is complying with applicable law and is not causing the Member to violate these Consumer Protection Rules.

Advertising Rules

  1. Prior to contracting with a lead generation Vendor, Members should conduct a reasonable due diligence investigation to ensure that the Vendor does not use misleading tactics or materials, including without limitation:

    1. Use of the term “free” (or any similar phrasing including “pay nothing” or “eliminate your bill”) unless the consumer will truly pay nothing for the solar energy system or the energy it generates.

    2. Claiming that the Vendor has a relationship with, or is endorsed by, any entity with which it has no formal relationship or has not received an endorsement, including any utility or governmental entity. This rule includes claims that the government “wants you to go solar,” using photographs of elected officials to imply a relationship or product endorsement, or any other similar misleading statement.

    3. Misleading or inaccurate claims about net energy metering or the availability of rebates or incentives (such as the expiration or value of the ITC).

    4. Characterizing any rebate, credit or incentive as “guaranteed” if the rebate, credit or incentive includes conditions and requirements (which most, if not all, do).

    5. Advertising the inclusion of “free" items (such as vacations or benefits unrelated to home improvement) that have no direct relationship with the solar/storage contract and/or the cost of which is included with the solar/storage contract, but not separately identified.

  2. To encourage Vendors’ compliance with these Advertising Rules, Members should consider including provisions in their contracts with lead generation Vendors that:

    12. Confirm the customer understands what warranties are included and their responsibilities under those warranties.

    13. Confirm that the customer understands what may happen if the home is sold.

    14. If the project includes a battery storage system, confirm the customer understands:  that the installation process may require additional steps, what in their home will be backed up, and how to use the backup outlet in case of an outage.

  5. Members who provide their customers financing to purchase solar electric home improvements (as defined in BPC section 7151) must conduct recorded confirmation calls (“Lender Confirmation Call”). A Lender Confirmation Call must take place before the start of construction and customers must be permitted to cancel the project contract any time during the call. Lender Confirmation Calls must include at least the following topics:

    1. Questions verifying the customer’s identity and contact information.

In some cases, your first payment may come due before your solar system is producing electricity and this can result in you having two bills.)

    4. Payment Method (Check/ACH) (i.e. addressing ACH interest rate).

  6. Unless the contractor provides payment and performance bonds per Business and Professions Code § 7159.5, contractors may not (under § 7159) charge for work not yet performed, collect deposits greater than permitted by law, or request payment in full until the project has passed inspection by the local building department. 

  7. In calculating estimated customer savings, projections should be based on the customer’s specific utility[4] and any annual utility escalator rate should not exceed the U.S. Energy Information Administration California residential electricity price increases over the previous ten years, or the CPUC’s standardized inputs per AB 1070 once they are available.
