WA Consumer Protections for Solar: Understanding House Bill 2156


The passing of House Bill 2156 is an exciting and significant milestone for WA state’s solar industry. This landmark legislation introduces comprehensive consumer protections addressing long-standing concerns about misleading sales practices and faulty installations. The bill includes requirements for solar energy contractors to ensure that solar customers are provided with clear and accurate information before making a solar installation decision. The legislation includes licensing requirements, along with specific contract language requirements and energy savings estimates. House Bill 2156 currently awaits Governor Jay Inslee’s signature and is anticipated to go into effect June 2024.

Key Highlights of HB 2156

Licensing Requirements:
  • Solar contractors must be licensed as per RCW 19.28.041
  • Design professionals involved in solar system design must also hold the appropriate professional licenses.
Contract Transparency and Financial Disclosures:
  • Detailed, written contracts are mandatory, including specifics like work to be performed, system components, performance expectations, and financing terms.
  • Contracts must be presented in the language used during the sales presentation.
  • Customers have a three-day right to cancel the contract without penalties.
  • Financing details must be clearly outlined, adhering to state and federal consumer loan regulations.
  • Contracts must disclose any dealer fees paid to lenders.
  • Contractors must inform customers about the potential effects of solar systems on property taxes
System Specifications, Warranties and Maintenance:
  • Itemized list of major system components to be installed and any necessary upgrades.
  • First-year annual production projections based on site-specific considerations.
  • Provide a good faith estimate of the first year’s electricity bill savings
  • A cost per watt calculation.
  • Disclosure of manufacturer warranties for major components
  • Outline of any ongoing maintenance costs.
Utility Interconnection and Code Compliance:
  • An approved interconnection application from the utility is required before installation.
  • Contractors are responsible for notifying utilities about equipment or design changes.
  • Contractors must disclose the requirement for system disconnect during power outages unless backup solutions are included.
Legal Responsibilities:
  • Entities purchasing or assuming solar installation contracts are subject to all customer claims against the original contractor.
  • Non-compliance with the law’s provisions subjects contractors to liability for actual damages sustained by the customer.
