The proposed bill establishes a new chapter in Title 19 RCW focused on consumer protections for solar energy systems in Washington State. It aims to ensure that solar energy salespersons and contractors provide accurate information regarding financing terms, total costs, and performance of solar energy systems to help customers make informed decisions. The bill outlines specific definitions related to solar energy systems, including terms such as "customer," "solar energy contractor," and "solar energy installation contract." It mandates that all solar energy installation contracts must be in writing and include detailed provisions, such as itemized costs, financing disclosures, and the contractor's responsibilities.

Additionally, the bill prohibits deceptive practices in the solicitation of solar energy systems and emphasizes that violations of these provisions are considered unfair or deceptive acts under the state's consumer protection laws. It requires that customers be informed of their rights, including a three-day rescission period during which they can cancel the contract without penalty. The legislation also holds solar energy contractors accountable for compliance with these requirements, ensuring that customers have legal recourse for any damages incurred due to non-compliance. Overall, the bill seeks to promote transparency and fairness in the solar energy market, protecting consumers from potential financial hardships.
