Balcony solar for renters and apartments — where it is legal, what it produces, when it pays back. Every figure sourced and dated.
The same three questions come up before every balcony solar purchase. Each of these answers one of them, on your own numbers, in about a minute.
Build PlannerPick a panel and a microinverter. Every pairing is checked against the published datasheets — voltage, current, and the watt cap your state actually allows.

Load calculatorTick the appliances you own. It works out how much of your own daytime use the kit offsets — and how much you hand back to the grid for nothing.

Kit finderThree questions about your balcony — which way it faces, how much railing you have, what you are allowed to drill. Then only the kits that survive.
Open it→Interconnection rules were written for rooftop arrays, not for a 400W panel clamped to a railing. Most states have never written a rule for plug-in solar at all — that is a gray zone, not a ban, and the rule that actually binds you is usually in your utility agreement or your lease. We track the statute, the cap and the utility position for all 51 US jurisdictions, each with the date we last checked it.

The guides published so far, plus the tracker that answers the question every buyer asks first.
Every number traces back to a datasheet, a statute or a published price — with the date we checked it.
Three questions about orientation, railing width and whether you rent. The finder rules out what physically will not work before it shows you anything else.

In the order that actually matters. Get the first one wrong and the other two do not apply.
Start with your state, then your utility's interconnection terms, then your lease or HOA. State law is usually silent — the rule that binds you is almost always the utility agreement.
Orientation and shade move the number more than the panel does. An 800W kit hung flat against a south-facing railing under clear sky makes about 751 kWh a year; a tilted bracket adds roughly 18%, and the same kit in shadow makes a fraction of it.
The same kit pays back in roughly two years in Hawaii and eight in Washington. Your electricity price decides it, not the hardware.
We publish the arithmetic, not just the answer. Every tool on this site shows the assumptions behind its number.
Output comes from NREL sun-hour data, electricity prices from EIA residential averages, and legal status from state statute and published utility tariffs. Where a source may have moved, the page says when we last checked it.

Questions
If yours is not here, the state tracker and the calculators answer most of them with your own numbers.
Open the toolsOne or two panels that hang on a balcony railing, a wall or a flat roof and plug into a normal outlet through a microinverter. No electrician, no roof work, and the kit comes with you when you move. They are also sold as balcony solar.
It depends on your state and your utility, and the rules are changing fast. Utah led with HB 340 in 2025, Maine followed with LD 1730 in 2026, and Virginia's law takes effect in January 2027. We track all 51 US jurisdictions — check the state guide for where yours stands today.
The panel feeds a microinverter, which converts DC to household AC and pushes it into the circuit your plug sits on. Your appliances draw that power first and pull the rest from the grid, so the meter simply sees you using less.
An 800W kit hung flat against a south-facing railing under clear sky makes roughly 751 kWh a year. A tilted bracket adds about 18%. Orientation and shade move that number far more than the panel does — the same kit in shadow makes a fraction of it.
Most 800W setups take $100–$250 a year off a US electricity bill, so payback usually lands between four and eight years. Your electricity price decides it, not the hardware: the same kit pays back in about two years in Hawaii and eight in Washington.
400W suits a balcony under 6 ft, 800W is the usual ceiling and wants roughly 6–8 ft of railing, and 1600W needs a wide balcony or a terrace. Wattage caps vary by state and by utility, so confirm yours before you buy.
Panels, a microinverter, the brackets or clamps that fit your railing, and a cable ending in a normal plug. Some kits add a monitor or an app. Nothing in the box needs an electrician to plug in, though your utility may still need telling.
The microinverter is the safety device: it is designed to shut down when it stops sensing grid voltage, so a cable pulled from the socket is not left live. Safety comes down to using a certified inverter and plugging into its own outlet rather than through an extension lead.
