The bill proposes the addition of a new chapter, Chapter 36, to Title 39 of the General Laws, which focuses on "Portable Solar Generation Devices." This chapter defines key terms related to portable solar generation, including "annualized billing period," "customer-generated electricity," "customer generation system," and "portable solar generation device." A portable solar generation device is defined as a moveable photovoltaic generation device with a maximum power output of not more than 1,200 watts, designed to connect to a building's electrical system through a standard 120-volt alternating current outlet. It is intended primarily to offset part of the customer's electricity consumption and must meet the standards of the most recent version of the National Electrical Code, as well as be certified by Underwriters Laboratories or an equivalent nationally recognized testing laboratory.

The bill outlines that a portable solar generation device is exempt from the interconnection requirements described in chapter 26.4 of title 39 and from the requirement to enter into an interconnection agreement pursuant to that chapter. It mandates that these devices include a feature that prevents the system from energizing the building's electrical system during a power outage. Furthermore, it specifies that an electrical corporation may not require a customer using a portable solar generation device to obtain the corporation's approval before installation or use, pay any fees or charges related to the system, or install any additional controls or equipment beyond what is integrated into the system. Additionally, the bill clarifies that electrical corporations are not liable for any damage or injury caused by the use of portable solar generation devices. This legislation aims to facilitate the adoption of small-scale solar energy solutions for residential customers.
