About Can I Plug In Solar
Can I Plug In Solar is built and run by one person, Jose Pollman. It answers two questions for renters, condo owners and homeowners in the US: is plug-in (balcony) solar legal in your state, and what would a kit on your balcony, patio or yard actually save?
States have been passing plug-in solar laws quickly since 2025. Most coverage of them quotes one statewide savings figure. But a north-facing railing and a south-facing patio can differ several times over, and a kit only saves money on power your home uses while the sun is up. So this tool runs an hourly model for your direction, tilt and utility rate, and shows how much of the output you'd simply give away.
Everything it uses is public: the US Census Geocoder, NLR PVWatts, the OpenEI Utility Rate Database and EIA price data. See how the site is paid for.
How we check the law
Each state's entry is read in the law itself: the statute or enacted bill text, and the legislature's own bill pages for status and dates. Where a law points to utility rules, we read the utility's tariff or the state regulator's page. News stories and summaries only tell us where to look.
We re-read every state at least once a month, and bills that are moving more often. Each state page links its source and shows the date we last checked it; the newest check across all states was . A detail we haven't read in the statute itself shows as "Not verified yet" and is left out of the calculator. See all 50 states and DC.
How we calculate
Every result, and every number in our guides, comes from the same model: hourly solar output for your spot, what your home uses as it's made, and your utility's rate. Each step and assumption is on how we calculate.
Corrections
Laws change and tariffs are messy. If a law card or a rate is wrong, please tell us: hello@canipluginsolar.com. Include the state or ZIP and, for a law, a link to the source.
When a state's law changes, or we correct one, we update that state's page and add the change to its key dates, with the date.
