| Option | Cost | Bill impact | Needs landlord OK? | Needs utility OK? | Moves with you? |
|---|---|---|---|---|---|
| Plug-in balcony kit | $285–1,600 | $100–400/yr | Lease-dependent; protected in CO, VA, NJ | No in enacted states; yes elsewhere | Yes |
| Portable panels + power station | $400–2,000 | Small (you charge devices, not the home) | No (nothing attached) | No (never connects to house wiring) | Yes |
| Community solar subscription | $0 upfront | 5–15% credit on bill | No | Handled by the program | Within the same utility, usually |
| Window-adjacent panel | $200–500 | $30–120/yr | Lease-dependent | Same rules as balcony kits | Yes |
Plug-in laws passed in 2025 and 2026 increasingly include a clause that landlords, HOAs or municipalities cannot ban the devices outright. Here is the language in each enacted or passed law, from our state dataset:
| State | Landlord / HOA provision |
|---|---|
| California | Not addressed in the law |
| Colorado | Not addressed in the law |
| Connecticut | Not addressed in the law |
| Maine | Not addressed in the law |
| Maryland | Not addressed in the law |
| New Hampshire | Not addressed in the law |
| New Jersey | Not addressed in the law |
| New York | Not addressed in the law |
| Utah | Not addressed in the law |
| Vermont | Not addressed in the law |
| Virginia | Not addressed in the law |
Everywhere else, including the 16 states with no bill, your lease and HOA rules decide. State "solar access" laws that stop HOAs from blocking rooftop panels generally do not mention plug-in devices, so do not assume they apply.
Landlords mostly worry about three things: damage to the building, liability if something goes wrong, and whether it is legal. Answer all three in the first email. A template that has worked for readers:
Subject: Request to use a small plug-in solar panel on my balcony
Hi [Name], I'd like to use a small plug-in solar kit on the balcony at [address]. It's a certified product ([brand, model], certified to [UL 3700 / UL 1741] by [lab]) that plugs into a standard outlet; nothing is wired into the building. It mounts to the railing with clamps or straps, no drilling, and I'll remove it and restore everything when I move out. [State] law [cite bill, if any] allows systems up to [X] W without utility approval. I'm happy to add it to the lease as an addendum, carry renters insurance, and show you the setup. Could you confirm that's okay?
If you are in Colorado, Virginia or New Jersey, you can add a line noting the law bars an outright ban and that you will comply with any reasonable placement rules.
Most apartments draw 150 to 400 W continuously during the day (fridge, router, standby loads, a laptop). A 360 to 800 W kit on a south-facing balcony covers most of that and rarely exports much, which is why self-consumption is high in apartments and why a battery usually does not pay for itself. Run your numbers in the calculator with "vertical on a balcony railing" selected.
In Colorado, Virginia (from 2027) and New Jersey (from March 2027), the law bars landlords and HOAs from prohibiting plug-in systems, though they may set reasonable size and placement rules. Vermont requires tenants to give 10 days' notice and lets landlords set reasonable restrictions. In most other states your lease governs, so get written permission before attaching anything to a railing or wall.
No. Railing hooks and clamp mounts, free-standing tilt frames, and weighted ground stands all avoid drilling. Zip-tie and grommet mounts (as used by Bright Saver) are the most lease-friendly option.
You unplug it and take it with you. That portability is the main reason plug-in solar fits renters better than rooftop solar. Check your new state's rules before plugging in again.
If your state has a program (New York, Illinois, Massachusetts, Maryland, New Jersey, Minnesota, Colorado and others), community solar usually saves 5 to 15% on your bill with no hardware and no landlord. It is the better choice for renters who cannot get sun on a balcony. The two are not exclusive.
Products marketed as window panels are mostly small, low-output, and often not grid-tied. Treat them as gadgets. A real 400 W panel hung outside a window on a proper mount is a different thing and falls under the same rules as balcony solar.
