As New England grapples with rising energy costs, a new wave of renter-friendly energy technologies is gaining traction, particularly the innovative concept of plug-in solar panels. These small-scale solar systems, designed to be easily installed and used by renters and apartment dwellers, are expected to become a more prevalent option in the region as state legislators across Maine, Massachusetts, Vermont, New Hampshire, and Rhode Island explore supportive legislation.
Plug-in solar units, which typically range from 200 to 1,200 watts, could provide a viable energy solution for many who have historically been excluded from the renewable energy transition. According to Maine State Senator Nicole Grohoski, a Democrat sponsoring a plug-in solar bill, these systems aim to level the playing field: “For many of my neighbors, especially renters, solar panels can experience like they’re meant for someone else. It’s about giving someone in a third-floor apartment the same chance to lower their electricity bill as a homeowner with a south-facing roof.”
Currently, most states prohibit these plug-in solar units due to existing electrical codes that assume a one-way flow of electricity from the grid into homes. However, the new systems allow electricity to flow back into a household’s electrical system through a standard outlet, reversing this traditional model. This innovative approach could help expand access to renewable energy.
Legislative Momentum and Market Potential
The push for plug-in solar technology is part of a broader movement in the United States, with at least two dozen states considering legislation this session. Utah became the first state to formally permit plug-in solar in 2025, marking a significant step forward. In Europe, the technology is well-established, with 25 of the European Union’s 27 countries allowing plug-in solar installations.
As the technology gains traction, major retailers like Home Depot and Costco remain hesitant to sell these units due to regulatory barriers. Proposed legislation aims to eliminate the need for special agreements with utility companies, which often arrive with significant costs and delays. By updating electrical codes, state lawmakers hope to lower the barriers that have previously hindered the adoption of these systems.
A recent study from Germany found that plug-in solar systems can pay for themselves in as little as two-and-a-half years, depending on usage and electricity rates. The costs for these units vary, with single 400-watt panels priced around a few hundred dollars, while larger 1,200-watt setups can exceed $2,000. After covering the initial investment, households could save hundreds annually on their electricity bills.
Benefits and Challenges for Renters
For renters and those unable to invest in rooftop solar installations, plug-in solar units represent a more accessible entry into clean energy. They require no permanent modifications to a property and can be taken along when moving. According to the Natural Resources Council of Maine, a 1,200-watt plug-in solar unit could potentially cut the average Central Maine Power customer’s electricity bill by approximately 21 percent.
However, critics caution that while these systems can provide renewable energy, they only contribute a modest portion of a household’s total energy needs. At prices up to $2,000, they may still be financially out of reach for many residents. “We see not a solution for low-income Vermonters,” stated TJ Poor, director of regulated utility planning at the Vermont Public Service Department, highlighting the financial barriers that still exist.
Safety Concerns and Future Developments
Safety remains a significant concern regarding plug-in solar technology. If these units send electricity back into an already utilized circuit, it could overload without the circuit breaker tripping as expected. Advocates argue that establishing clear rules and standards is essential to address these safety issues and facilitate the widespread adoption of the technology.
As New England states move forward with proposed legislation, the landscape for renewable energy is shifting. In Boston, for instance, a pilot program is testing window-mounted heat pumps, which could further enhance energy efficiency in urban settings. The legislative efforts in Maine, Rhode Island, New Hampshire, and Vermont are gaining traction, with several proposals advancing through committees, and Vermont’s bill already passing the Senate. Massachusetts is also examining plug-in solar as part of a broader climate bill.
Even with legislative support, the availability of plug-in solar units may hinge on national electrical safety certifications, a process that is underway and expected to conclude within the next year. If successful, these developments could represent a significant shift in how clean energy is accessed, making renewable energy more attainable for those traditionally left out of the solar movement.
As states continue to evaluate and potentially pass plug-in solar legislation, the implications for renters and the broader energy market could be profound. This technology could set a precedent for how clean energy is integrated into urban living, paving the way for a more inclusive and sustainable energy future.
