Plug-In Solar FAQ: For Renters and Landlords
Solarly is independent and ad-free. We have no financial relationship with any solar installer or kit manufacturer. These answers come from public legislation, utility data, and documented court cases.
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. You don’t need a roof, an installer visit, or (in most states) an electrician. And when you move, it moves 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. The Solarly calculator will show you what it works out to at your rates.
Is it legal where I live?
Nine states have enacted laws explicitly protecting plug-in solar and removing the utility approval process: Utah, Virginia, Maine, Colorado, Maryland, Connecticut, Vermont, New Hampshire, and now New Jersey. Governor Sherrill signed the Garden State Balcony Solar Act on September 1, 2026, and it takes effect March 1, 2027. Two bills are still waiting on governors as of mid-September 2026: California (SB 868, passed the legislature August 26; Governor Newsom has until September 30 to act) and New York (SUNNY Act). In states without a specific law, plug-in solar isn’t automatically illegal; there’s just no framework for it yet. In practice, the questions that matter most are what your utility allows and what your lease says. Our Solar Laws by State page has the current picture.
Do I need an electrician or a permit?
In the nine 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, and Maryland and Virginia require you to notify your utility before you install. Virginia’s law and New Hampshire’s law both take effect January 1, 2027, and New Jersey’s follows on March 1, 2027. It’s worth checking your state’s 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; as of September 2026, two microinverters (the APsystems EZ1 and the Hoymiles HiFlow Pro) have been certified to it by CSA Group, but no complete kit has been certified as a whole system yet. 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, no. Most modern digital meters don’t allow reverse spinning. In states without net metering for plug-in solar, anything you generate beyond what you’re using at that moment goes to the grid for free, so 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, and that’s one of the nicest parts. A plug-in system is personal property, like a piece of furniture. There’s 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, but they don’t change your landlord’s authority over the property. Vermont is the exception today: you can install after giving your landlord 10 days’ notice, and they can respond with reasonable restrictions. Three more states follow. Starting January 1, 2027, Virginia bars landlords with more than four rental units from refusing, and Colorado bars unreasonable bans. New Jersey joins them on March 1, 2027, for tenants who pay their own electric bill. Everywhere else, if your lease prohibits exterior modifications or equipment installation, that clause is still enforceable. So ask your landlord before you install anything, even if you think a state law is on your side; in most states, it isn’t 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 Vermont, you can go ahead after giving your landlord 10 days’ notice; they can respond with reasonable restrictions. Starting January 1, 2027, a Virginia landlord who owns more than four rental units cannot ban a qualifying plug-in solar device, though they can set reasonable restrictions on placement, and Colorado landlords and HOAs cannot unreasonably prohibit compliant systems. New Jersey adds similar protection on March 1, 2027. 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. Vermont’s law already stops covenants from prohibiting plug-in devices. Colorado’s ban on HOA prohibitions starts January 1, 2027, and New Jersey’s Garden State Balcony Solar Act does the same once it takes effect on March 1, 2027. No other US state compels a co-op board or HOA to approve balcony solar. That leaves you with negotiating, looking into a window-mounted system, or exploring community solar.
For landlords
The concerns we hear most, taken seriously
If your tenant pointed you here, thanks for taking the time to read. Below are the objections we hear most often, answered with sources. Most landlords who look at the actual evidence end up somewhere different from 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’s a completely reasonable condition to set.
“I’m worried about my building’s wiring.”
There’s a real technical issue here, and it’s 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’s 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’re 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; only two microinverters carry it so far and no complete kit does, so requiring it outright would be premature. If your tenant can’t show UL 1741 certification (or an equivalent listing, like ETL/Intertek), that’s a fair reason to say no.
“What if my insurance doesn’t cover it?”
It’s 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 isn’t attached to the structure, and it’s 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’s 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’s fair. It’s worth knowing where things are heading, though. Vermont already limits what landlords can do. Starting January 1, 2027, Virginia bars landlords with more than four units from refusing these requests, and Colorado bars unreasonable bans. New Jersey signed the same kind of protection into law on September 1, 2026, effective March 1, 2027. 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?
Most tenants will readily agree to all of this:
- 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, is certified on only two microinverters and no complete kits so far, so it 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 isn’t a niche question there; it’s 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. Vermont is furthest along today: tenants can install after giving notice, and landlords can only respond with reasonable restrictions. Virginia’s law will stop landlords with more than four units from banning balcony solar outright on January 1, 2027, Colorado bars unreasonable landlord and HOA bans from the same date, and New Jersey’s new law does the same starting March 1, 2027. 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.
