10 States Now Allow Plug-In Solar Panels for Apartments

Imagine generating your own solar power without spending tens of thousands of dollars or even owning your home. That's exactly what's happening as plug-in solar panels transform how Americans access clean energy.

Andrew Leon and Victoria Mauro plugged three small solar panels into an outlet outside their Utah home, and now they're powering their laptops, lights, and refrigerator with sunlight. No complicated installation, no rooftop drilling, just simple panels that work like any other appliance.

California just joined nine other states making these systems legal and easy to install. Utah led the way in spring 2025, followed by Colorado, Connecticut, Maine, Maryland, New Hampshire, New Jersey, Vermont, and Virginia. New York's bill awaits the governor's signature, while nearly two dozen more states are considering similar laws.

The setup is remarkably simple. One to three panels connect to a small metal inverter box that plugs into any standard outlet. The electricity flows to other outlets throughout your home, typically covering 10 to 30 percent of an average household's power needs.

Nick Danz spent under $300 for a single panel he clipped to his Fort Collins apartment balcony. Working as a train conductor four days a week, he's already saved more than $300 since August because the panel runs all his standby appliances while he's away.

Europe has already embraced this technology enthusiastically. Germany alone has installed more than a million units in recent years, and Swedish furniture giant IKEA now sells plug-in solar kits there.

The appeal goes beyond environmental benefits. Electrical engineer Joshua Pearce calculated Americans could save $13 billion yearly in electricity costs with widespread adoption. That figure has likely grown as electric rates continue rising.

The Ripple Effect

This technology opens solar power to millions who couldn't access it before. Renters no longer need landlord permission for expensive rooftop installations. Apartment dwellers with sunny balconies can start generating clean energy today.

Safety concerns have been addressed through rigorous testing. UL Solutions set safety standards this year and has already certified manufacturers. Despite widespread European use, plug-in systems have never caused the house fires some worried about.

The movement builds momentum as more products reach the market and states eliminate regulatory barriers. Jennifer Eden from Utah Clean Energy notes people are especially excited about "an entry point into solar that doesn't cost tens of thousands of dollars and can be used by people who don't own their home."

As solar panels become as easy to install as window air conditioners, clean energy is finally becoming accessible to everyone with a sunny window or balcony.
