Plug-in solar, explained plainly.
An independent US guide to the small solar kits that plug into your home: what’s legal, what’s safe, and what’s worth buying.
Plug-in solar is new in the US. Rules differ from state to state and change quickly, and the products on sale range from certified systems to listings with vague claims. Borizo exists to answer three questions in plain English.
What we help you figure out
Is it legal where I live?
Our state pages link straight to the law or bill text and show the date we last checked it.
Is it safe?
We explain wattage limits, circuits and certifications like UL 1741 and UL 3700, and what they do and don’t mean.
Is it worth buying?
Our calculators estimate savings and payback using your own electricity rate and sun hours.
Who we are
Borizo is written and maintained by the Borizo Editorial Team. We are publishers and researchers, not electricians or lawyers, and nothing on this site is legal or electrical advice.
How we compare products
Unless a page clearly says otherwise, our kit comparisons are spec-based: we compare published specifications, certifications and listing details. We never claim to have tested a product we have not tested.
