For renters
Getting started
What is plug-in solar, exactly?
A small panel, typically 400 watts, that converts sunlight to electricity and plugs into a standard wall outlet. No roof, no electrician in most states, no installer visit. When you move, you take it with you.
How much can I actually save?
At the US average rate of about 15 cents per kilowatt-hour, a single 400W panel saves roughly $5 to $23 a month. In high-rate states it goes further: California is around $13 to $15 per month, New York around $10 to $12, Hawaii around $18 to $19. A single panel typically pays for itself in 3 to 5 years, then keeps saving for the rest of its 20 to 25 year lifespan. Use the Solarly calculator to see your numbers.
Is it legal where I live?
Eight states have enacted laws explicitly protecting plug-in solar and removing the utility approval process: Utah, Virginia, Maine, Colorado, Maryland, Connecticut, Vermont, and New Hampshire. Two more bills are pending governor signatures as of mid-2026: California and New York. In states without a specific law, plug-in solar is not automatically illegal — there is just no framework for it yet. The main legal questions in most states are your utility policy and your lease. Check our Solar Laws by State page for the current picture.
Do I need an electrician or a permit?
In the eight states with enacted laws, no permit and no electrician are required for systems under 1,200 watts connected through a standard outlet (Colorado allows up to 1,920W). Maine requires a licensed electrician for systems over 420W. Virginia’s law and New Hampshire’s law both take effect January 1, 2027. Check your state rules before you buy.
Is plug-in solar actually safe? What certification should I look for?
Certified kits are designed to be safe, with automatic anti-islanding shutoff, overload protection, and automatic disconnect if the grid goes down. Today, look for UL 1741 — the established safety standard for grid-connected inverters. You may also see mention of UL 3700, a newer standard written specifically for plug-in solar; it launched in early 2026, but as of late July 2026 no product has completed certification under it yet — UL Solutions says it expects to certify the first ones soon. UL 1741 (or an equivalent recognized listing, like ETL/Intertek) remains the most widely available certification to check for today.
Will my electricity meter run backwards?
Not reliably. Most modern digital meters do not allow reverse spinning. In states without net metering for plug-in solar, any electricity you generate beyond what you are using at that moment goes to the grid for free. The savings come from using your own solar power in real time instead of buying it from your utility.
Can I take the panels with me when I move?
Yes. A plug-in system is personal property, like a piece of furniture. There is no permanent installation, and nothing to negotiate with your landlord when you leave.
For renters
Talking to your landlord
Do I need my landlord’s permission?
In most states, yes. The laws that have passed remove the utility as a barrier — they do not change your landlord’s authority over the property. Virginia prohibits landlords with 4+ units from refusing, and Colorado prohibits outright bans. Everywhere else, if your lease prohibits exterior modifications or equipment installation, that clause is still enforceable. Ask your landlord before you install anything, even if you think a state law is on your side. In most states, it is not yet.
What is the best way to ask?
A few things that tend to help:
- Ask in writing. Email gives your landlord time to think it through rather than react on the spot.
- Be specific. “I’d like to hang a 400-watt solar panel on my balcony railing, clipped to the rail with no drilling” lands better than “I want to install solar.”
- Get ahead of their concerns. Before they ask, mention that the system is fully removable, that you will restore the balcony when you leave, and that it is UL 1741 safety certified.
- Offer a written addendum. Landlords who are nervous about liability often come around when everything is in writing. You take on responsibility for any damage, and you commit to removing the system when you move out.
- Share this page. The landlord section below addresses the most common concerns with data.
My landlord said no. What are my options?
It depends on where you live. In Virginia, if your landlord owns 4 or more rental units, they cannot legally ban a qualifying plug-in solar device, though they can set reasonable restrictions on placement. In Colorado, landlords and HOAs cannot prohibit compliant systems but can impose safety conditions. In most other states your options are limited:
- Try again with more information. Many landlords say no reflexively. The section below is written to help change that.
- Negotiate a lease addendum. Some renters have added specific solar language when renewing.
- Look into window-mounted panels. A smaller panel that sits inside a window does not affect the building exterior and may not require permission.
- Check community solar. If individual installation is not an option, community solar programs let you buy into a share of a solar farm and get credits on your bill. No permission needed. Check your utility’s website or EnergySage to find programs near you.
My HOA or co-op board said no. What now?
HOA situations are harder. California’s Solar Rights Act limits HOA restrictions on rooftop solar, but it was written for permanently installed systems and almost certainly does not cover plug-in balcony panels. Colorado explicitly prohibits HOA bans on compliant plug-in solar. No other US state currently compels a co-op board or HOA to approve balcony solar. Your options: negotiate, look into a window-mounted system, or explore community solar.
For landlords
Common concerns, straight answers
If your tenant pointed you here, thank you for reading. These are the most common objections we hear, with honest answers and sources. Most landlords who look at the actual evidence end up in a different place than their first instinct.
“What if it falls off the balcony?”
A panel clipped or strapped to a balcony railing using the manufacturer’s hardware is designed to hold up in standard wind conditions. Think of it like a window AC unit, which most leases already allow. A typical panel weighs 4 to 8 kilograms, about the same as a large bag of dog food. If you want to be sure, ask your tenant for the manufacturer’s mounting specifications before you approve. That is a completely reasonable condition to set.
“I’m worried about my building’s wiring.”
There is a real technical issue here worth understanding. Plug-in solar panels push electricity back into your home’s wiring through the outlet, which is the opposite direction from normal appliances. In older buildings, there is a theoretical risk that a breaker might not accurately read the total load on a circuit. Certified systems are designed to stay well within safe limits, and they are required to shut down automatically if the grid goes down. A single 400W panel on a standard 15-amp circuit operates at a fraction of that circuit’s capacity. A space heater or window AC draws significantly more power and is typically allowed under most leases. The key question is whether the system is certified. Ask your tenant to show you UL certification for the inverter — today that means UL 1741, the established standard for grid-connected inverters. You may hear about UL 3700, a newer standard written specifically for plug-in solar; it launched in early 2026, but as of late July 2026 no product has completed certification under it yet — still uncommon enough that requiring it outright would be premature. If your tenant cannot show UL 1741 certification (or an equivalent listing, like ETL/Intertek), that is a fair reason to say no.
“What if my insurance doesn’t cover it?”
Worth checking with your insurer, but most standard landlord policies treat a clipped-on solar panel as tenant personal property, not a building modification. It is not attached to the structure, and it is fully removable. If you want extra protection, ask your tenant to carry renter’s insurance and list you as an additional interested party. That covers both of you. In Germany, where over 1.3 million of these systems are installed in apartment buildings, landlord insurance complications have not emerged as a documented problem.
“I don’t want the building to look like a solar farm.”
One panel on one balcony looks like one panel on one balcony. If you manage a larger property and want consistency, a placement policy works better than a blanket ban. Something like “panels must be mounted below the railing and not visible from the street” gives you control without turning down every request. German courts have ruled that a landlord’s general discomfort with how solar panels look is not a valid reason to refuse. Documented impact on a landmarked building’s street-facing facade is a different matter.
“Won’t this set a precedent?”
Probably yes, and it is worth thinking through what that actually means. Each request is the same: one small panel, standard outlet, removable. Having a clear written policy about what you will approve and what conditions you require is a lot easier to manage than making one-off decisions every time someone asks. Consistency protects you.
“I just don’t want the hassle.”
That is understandable. But it is worth knowing where things are heading. Virginia now prohibits landlords with 4 or more units from refusing these requests. Colorado prohibits bans. More states are moving this direction every year. Germany, which has over 1.3 million installations in apartment buildings, found that the fire risks, electrical concerns, and aesthetic objections landlords raised before adoption never materialized at scale. A simple written policy with clear conditions is probably less work over time than a blanket no that gets harder to justify as the law catches up.
What conditions should I set if I say yes?
Here is what most tenants will readily agree to:
- The system must carry UL 1741 certification (the standard for grid-connected inverters) or an equivalent recognized listing, like ETL/Intertek — UL 3700, the newer standard written specifically for plug-in solar, has no certified products yet as of late July 2026 and is not yet widely available
- It must be installed using the manufacturer’s recommended hardware
- The tenant commits in writing to remove it and restore the balcony on move-out
- The tenant maintains renter’s insurance that covers the system
- The system cannot exceed a specified wattage (800W or 1,200W are common choices)
- Panels must stay within the balcony railing and not extend beyond it
These are easy to add as a lease addendum. LinkSolar has a free landlord policy template you can adapt.
For everyone
How other countries handle this
Why does everyone keep talking about Germany?
Because Germany is the only country that has figured this out at scale. As of mid-2026, Germany has over 1.3 million registered balcony solar systems, and estimates suggest the true number including unregistered units is significantly higher. More than half of Germans rent their homes, so renter solar access is not niche there. It is a mainstream policy issue. They got there in two steps: simplified utility rules in 2024, then gave renters an enforceable legal right to install over a landlord’s objection in October 2024. Adoption accelerated sharply after the tenant rights law passed.
What can the US learn from Germany?
Two things. First, the concerns landlords raised in Germany before adoption — including fire, electrical damage, and aesthetics — did not become real problems at scale. Second, getting from “interesting technology” to mainstream adoption requires both the utility side, which US states are working on, and the property-rights side, which almost no US state has tackled yet. Virginia is closest. It prohibits landlords with 4 or more units from banning balcony solar outright. Colorado prohibits landlord and HOA bans but allows safety-related restrictions. Every other state still leaves the landlord fully in charge.
What do other European countries do?
Most European countries treat truly non-invasive installations (no drilling, railing-clip only) as appliances that do not require landlord permission. France explicitly exempts balcony panels that require no structural modification from the category of home improvements that need landlord consent. The Netherlands works the same way. Belgium legalized the technology in April 2025 but left landlord-tenant relations to contract law. Germany is the only country where tenants have a statutory right that can actually override a landlord’s refusal.
