One of the most promising climate solutions that is in reach for LOTS and LOTS of people in the US is plug-in solar (aka balcony solar). Personally, I couldn’t be more excited about this particular way of reducing emissions, saving money, and democratizing energy!
Plug-in solar systems are small panels that plug-into a regular wall outlet, just like a toaster! You don’t need any fancy equipment or expertise to install them – they’re easy to attach to a balcony or deck railing, a fence, or even just on brackets in your yard. (Though I’m clumsy enough with DIY projects that, if I had a place to put one of these, I’d ask my neighbor Kate to lend me her hands for a few minutes to get the job done well.)
Unlike with large rooftop solar arrays, to get balcony solar, you don’t need thousands of dollars upfront, you don’t need to hire anyone, you don’t need to wait for and pay for a permit, you don’t need access to your roof, and you don’t even need to own your own home. Finally, clean energy generation for us renters of the world!
When the sun shines on them, these systems feed energy into your home to power things like your refrigerator, but without drawing power from the grid. So they reliably save you money and can pay for themselves in just a couple years (timing varies depending on how much sun you get and local electric rates – check out this tool to calculate for yourself).
These systems are safe. There are well over a million in Germany alone, with many more across Europe – and they’ve been in use for years without incident. If the power goes out, they automatically turn off, so they won’t hurt any electric workers doing repairs to get the grid back up. But they can be attached to a battery, which would come in handy during a longer outage!
9 US states currently have laws in place allowing for these systems – Utah was the first to pass that (bipartisan!) legislation (unanimously!) in 2025. In the other states, the only laws on the books regarding solar are old laws, with much bigger systems in mind, which is why so many folks are working so hard to get legal permission for balcony solar systems extended to more states – you can see where things stand in your state here. (Hurry up, Illinois, there are lots of balconies in Chicago that are perfectly suited for these small systems!)
If you’re interested in learning more or buying a plug-in solar kit, I recommend you check out Bright Saver. They are a 501c3 non-profit that educates the public, lobbies for state legislation allowing plug-in solar, and sells plug-in solar systems at cost (with no markup, no profit for themselves)! That makes them the most affordable systems I know of.
If you become a member for $29 (as I did), you can get a 180W system for less than $300. I decided that even though I don’t have a place to put a panel like this right now, I want to support them right now! And full disclosure, that’s a referral link in the previous paragraph, because I definitely want to see massive uptake of balcony solar, and I wouldn’t mind getting a Bright Saver t-shirt as a referral reward and conversation starter.
Because I’ve been talking to folks about balcony solar every chance I get for the last year and a half, and everyone I’ve spoken to gets it right away: plug-in solar is a game-changer. People want these things, and they want them now. Let’s help lots of folks learn about and get them!
