There's no mistaking the growing momentum behind small-scale, low-cost solar panel installations: panels you can plug into a standard wall outlet, without the expense, time, or paperwork of a full rooftop installation.
Now widely established in Europe (where the tech is best known as 'balcony solar'), we're starting to see a wave of American states move towards legalizing these plug-in panels as well. Utah was the first in 2025, and there are now proposals in 30 other states to make the devices available to buy.
