Some States Now Allow Solar Panels to Be Plugged Into a Wall Outlet

Plug-in solar setups are compact, yet they can help renters and homeowners save hundreds of dollars each year.

When you purchase a new refrigerator, you simply plug it in and use it right away.

In an increasing number of states, adding a few solar panels is becoming nearly as straightforward.

Plug-in solar systems connect to a standard outlet and send electricity directly into a home. Liz Veazey works with the nonprofit Solar United Neighbors.

Veazey said the group is encouraged by plug-in solar because it can expand access for people who cannot install rooftop systems. That may include apartment renters or homeowners whose roofs are too shaded, but who may still have a porch or another spot for a few small panels.

These systems are usually modest, with only two or three panels. Even so, that setup can reduce utility costs by several hundred dollars a year.

Veazey called it a simple way to bring down energy bills with solar power.

Plug-in solar remains uncommon in the U.S. because most states still lack a legal structure for regulating these small systems.

That is beginning to change. More than eight states have adopted policies that allow and oversee plug-in solar systems, and bills have been introduced in several others.

As those rules spread, more people may soon be able to plug in a solar panel and begin producing clean energy at home.
