This bill introduces a new definition for "plug-in solar generation system," allowing each metered customer to install one such system with a maximum inverter output of 1,200 watts AC. The bill exempts compliant systems from utility approval, interconnection reviews, and related fees, provided they meet national safety standards and are installed according to the state building code and manufacturer instructions. The Department of Energy is tasked with maintaining consumer information on plug-in solar generation systems and is authorized to adopt rules consistent with ANSI, UL, and IEEE standards. Additionally, electric distribution utilities are not liable for damages arising from customer-installed systems.

The bill also mandates that the building code review board amend the state building code to address the use of plug-in solar generation systems. It specifies that customers are not required to obtain utility approval or pay additional fees for compliant systems, and it clarifies that connecting unlisted systems may affect insurance coverage. The effective date for the provisions related to the building code will be contingent upon the certification of a nationally recognized standard for safe connections, while the remainder of the act will take effect on January 1, 2027.
