Balcony solar is this year’s clean energy superstar in the US

Balcony solar, small solar panels that hang outside a window or railing and plug straight into a regular wall outlet, is spreading fast across the country. The idea is simple: the panels cut how much power you pull from the grid, lowering your electric bill without any big installation. Germany has used them for years, but at the start of 2026, Utah was the only U.S. state that had legalized them. That's changed quickly. Virginia legalized plug-in solar in April, and Colorado and several Northeast states followed. As of now, nine states have balcony solar laws on the books, with three more bills passed and awaiting governors' signatures. More than two dozen state legislatures have introduced similar bills this year, so the list is likely to keep growing.

Even if your state has legalized the panels, buying them isn't as easy as it is in Germany, where you can pick some up at Ikea. Only a handful of vendors currently sell plug-in solar kits in the U.S., partly because of how state and federal electrical codes are written. Whether more American manufacturers start making these systems, and which state legalizes them next, is still an open question.

If you live in one of the states that has passed a balcony solar law, or in one considering a bill, it may be worth checking your state's rules to see whether plug-in panels are an option for your home and what vendors currently sell them.
