Residential solar energy solutions, specifically designed for balconies and decks, are becoming increasingly popular in the United States.
Plug-in Solar Systems Gain Momentum in the U.S.
Plug-in solar systems, often referred to as "balcony" solar kits, are becoming increasingly popular in the United States due to their affordability and simplicity compared to traditional rooftop solar systems. However, their adoption remains less widespread than in Europe due to regulatory and utility policy challenges.
Advantages of Plug-in Solar Systems
These smaller systems offer lower upfront costs, with a small plug-in system costing around $2,000 compared to rooftop setups that can cost tens of thousands of dollars. Installation is also simplified as they can be plugged into a standard wall outlet.
Regulatory and Utility Policy Barriers
Despite their technical distinctions, some utilities apply rooftop solar standards to plug-in kits, complicating approvals and discouraging uptake. The U.S. regulation around plug-in solar remains fragmented, with a lack of standardized, streamlined interconnection procedures limiting broader deployment.
Current Market Scenario
Residential solar overall experienced a slowdown in early 2025 due to high interest rates, economic uncertainty, and federal policy changes. However, utility-scale solar is expanding rapidly, especially in Texas. Solar system prices have seen some fluctuation, but residential system costs remain higher due to smaller scale and system components.
Case Studies
Craig Keenan, a Baltimore resident, installed a plug-in solar system on his balcony in July, expecting it to save him about $40 per year on utility bills, taking him about 10 years to recoup the cost of the kit. Terrence Dwyer, a resident of Oakland, California, recently installed a plug-in solar system on his backyard deck and reports savings of about $35 per month on electricity.
Future Outlook
The future of plug-in solar in the U.S. is expected to increase, particularly as utility and regulatory frameworks evolve to better accommodate these systems. As federal residential rooftop solar tax credits end and economic conditions push users toward lower-cost solar alternatives, consumer interest is likely to rise.
Integration of plug-in solar with battery storage and smarter grid management, as well as lessons from European markets, might drive future policy reforms to facilitate easier interconnection and incentives. Long-term U.S. residential solar capacity could grow substantially by 2050, potentially exceeding present total U.S. power generation capacity as technologies and policies mature.
Manufacturers' Perspective
Kenneth Hutchings, Craftstrom's chief revenue officer, expects demand for plug-in solar to increase further as federal rooftop solar credits expire. Ryan Oliver, a company spokesperson for EcoFlow, stated that plug-in solar technology is ahead of the regulators and expects it to become more mainstream as people understand it better.
The plug-in solar system consists of two 400 watt panels, an inverter, a smart meter, and a circuit breaker. The demand for these systems has been increasing, with some manufacturers seeing positive signs such as a new Utah law streamlining regulations for homeowners to buy and install them.
In summary, plug-in solar systems in the U.S. currently face regulatory and utility policy barriers that slow adoption compared to Europe, though they offer significant cost benefits and growing consumer appeal. The future likely involves gradual policy adaptation and increased market penetration as federal incentives decline and demand for affordable solar solutions grows.
