HB39 amends Maryland’s net energy metering law to expressly allow an eligible customer-generator to use a “portable solar” electric generating facility for net metering. The bill defines portable solar as a movable photovoltaic system with an inverter rating up to 120 kilowatts, designed to plug into a standard 120-volt outlet, intended primarily to offset the customer’s own electricity use, and required to meet National Electrical Code and nationally recognized testing standards. In practical terms, the bill expands the types of solar equipment that can qualify for net metering, while keeping the equipment tied to the customer’s premises or contiguous property and subject to the existing framework for interconnection and billing.
The bill leaves the broader structure of Maryland’s net metering program in place, including the requirement that utilities offer standard net metering contracts or tariffs, the treatment of excess generation, and the existing program cap of 3,000 megawatts. It also preserves the current rules on two-way metering, compensation for net excess generation, safety standards, and utility reporting to the General Assembly. The bill does not create a new subsidy program; instead, it clarifies that portable solar systems can participate under the same net metering rules as other eligible renewable systems.
HB39 would affect the Public Utilities Article, specifically Section 7-306, by adding portable solar to the definition of eligible customer-generator and by incorporating portable solar into the list of qualifying generation technologies. It could benefit homeowners, renters with qualifying property access, small businesses, and other customers who want a more flexible solar setup, while also affecting electric companies, electric cooperatives, and the Public Service Commission, which would continue to administer and oversee the program. Because the bill is framed as an amendment to existing net metering law, its legal impact is targeted rather than sweeping.
There is no recorded committee testimony or vote history in the provided materials, so no formal legislative sentiment can be measured from hearings or roll calls. Based on the bill text alone, the measure appears generally supportive of distributed renewable energy and consumer access to solar, with a policy emphasis on encouraging private investment and reducing interconnection barriers. The absence of recorded opposition in the supplied context means any contention is inferred from the subject matter rather than documented debate.
Potential points of contention are likely to center on utility concerns about grid safety, interconnection standards, and whether portable plug-in solar systems should be treated the same as permanently installed rooftop systems. Questions may also arise about how the 120-kilowatt portable-solar definition would be implemented, whether such systems could be used on rental or shared properties, and whether the existing net metering framework adequately addresses billing, inspection, and liability issues for movable equipment.
HB39 would amend Maryland Public Utilities Article § 7-306 to add “portable solar” as a qualifying technology for eligible customer-generators under net energy metering. This would expand access to net metering for movable photovoltaic systems that meet specified capacity, connection, and safety standards, while leaving the rest of the state’s net metering structure intact, including utility tariff requirements, compensation for excess generation, and the 3,000-megawatt statewide cap.
The available context shows no committee transcript or vote record, so there is no documented floor or hearing sentiment to summarize. From the bill’s language, the measure appears broadly pro-renewable and pro-consumer, aimed at making solar participation easier and more flexible rather than changing the overall policy direction of net metering.
No specific opposition is documented in the provided materials. Likely areas of debate include utility concerns about grid reliability, safety, and interconnection for plug-in solar devices, as well as questions about how portable systems would be verified, inspected, and billed under existing net metering rules. There may also be policy disagreement over whether portable solar should receive the same treatment as permanently installed generation.
