People across the US have started to use small plug-in solar panels as an affordable way to cut electric bills
Across the country, Americans are discovering that plug-in solar panels are making solar power cheaper and easier than ever.
Instead of spending tens of thousands of dollars on rooftop systems, some households are turning to compact kits that cost a few hundred dollars and take less than an hour to set up.
The idea is simple: mount a small panel on a balcony, backyard wall, or carport and plug it into a standard outlet.
Just like that, you are generating your own electricity.

This is perfect for those who can’t afford fancy rooftop systems
The concept has already taken off in Germany, where so called ‘balcony solar’ systems are common.

Now, the trend is gaining traction in the United States.
For retirees like Agnes Chan in Berkeley, California, the appeal is obvious.
Living on a fixed income, she wanted rooftop solar but could not afford the steep upfront cost.
Instead, she bought a $400 plug-in system that she expects will pay for itself in just two to three years.

Her goal is simple: lower bills that run into the hundreds of dollars and make her drafty home a little more comfortable in winter.
Plug-in solar systems are small and modular.
You can start with one panel and add more over time.
That flexibility makes them attractive to renters and people in multifamily housing who have traditionally been locked out of rooftop solar.
Joe Tenenbaum, another California resident, opted for $1,600, 800-watt plug-in solar panels after realizing a full rooftop installation would require replacing the roof and investing close to six figures.

Since he does not own the house, that was not realistic.
His plug-in setup will not power everything, but it can keep the refrigerator running and small appliances charged, trimming about 5 to 10 percent off his monthly bill.

Plug-in solar panels still face several hurdles
In much of the US, simply plugging in a solar panel is not technically legal without going through the same registration process required for rooftop systems.

Utilities argue that oversight helps them manage grid safety and demand.
Some engineers warn that uncertified systems could pose risks, such as energizing downed power lines.
However, experts say modern micro-inverters and existing electrical codes can address many of these concerns, and new safety standards are in development.
A few states are already moving forward to legalize this new technology.
Utah recently passed legislation allowing plug-in solar without registration when certain safety standards are met.
Lawmakers in other states are considering similar measures.
Even if plug-in solar only covers a slice of national energy demand, supporters say every watt of renewable energy counts.
And for many Americans, opening a box and seeing their own panel generate power feels a bit like unwrapping a very practical gift.
