Oregon HB 4080: Proposed Rules for Portable Solar Photovoltaic Devices

Hey there, fellow Oregon landlords, property managers, and real estate investors. Christian Bryant here from the Portland Area Rental Owners Association (PAROA). The 2026 legislative session is off to a quick start, and House Bill 4080 is one of those early filings that touches on energy use in residential properties. Titled "Relating to portable solar photovoltaic energy devices; prescribing an effective date," this bill focuses on giving retail electricity consumers the ability to install and use small-scale portable solar setups.


Mr Portland Landlord reports this article.

As of late January 2026, HB 4080 is newly introduced and sitting at the House Desk, awaiting first reading. No sponsors are listed yet on the official overview, no committee assignment, and no hearings scheduled—it's very much in the beginning phase. The full introduced text is available as a PDF on the Oregon Legislative Information System (OLIS), linked below. The catchline and summary are straightforward: the bill allows a retail electricity consumer to install and use portable solar photovoltaic energy devices with a total maximum generating capacity of 1,200 watts.

Oregon portable solar photovoltaic devices

What exactly are we talking about here? Portable solar photovoltaic devices are those plug-and-play systems—think small panels you can set up on a balcony, windowsill, or yard, connected directly to a standard electrical outlet via an inverter. No roof mounting, no permanent wiring, no big installation crews. These have gained popularity in apartments and rentals elsewhere because they're easy to move and don't require owner permission for structural changes. The 1,200-watt cap keeps it small-scale—enough to offset some appliance use or charging, but not a full home system.

Simple and portable: Up to 1,200 watts allowed under proposed Oregon portable solar photovoltaic devices rules.

Current Oregon law doesn't explicitly prohibit these, but barriers exist. Utilities might have interconnection rules, even for tiny systems. HOAs or landlords could ban them under lease terms or covenants, citing aesthetics, safety, or electrical concerns. HB 4080 appears designed to clear the path, creating a specific right for consumers (which includes tenants) to use these devices up to the wattage limit, potentially overriding certain restrictions.

If passed as introduced, here's how it could play out for us in the rental housing world.


For landlords and property managers: Tenants would gain a clearer legal pathway to deploy portable solar panels without needing your approval for "installation," since these are truly portable and plug-in. That means a renter in a duplex or apartment could set up panels on their balcony or patio, plug them in, and generate a bit of their own power—reducing their utility bill while your property's common systems stay unaffected. On the positive side, it could make your units more attractive to eco-conscious applicants, especially younger renters prioritizing sustainability. Lower individual utility costs might even improve payment stability if tenants have more disposable income.


But let's look at potential challenges. Electrical safety tops the list—plugging into standard outlets assumes the building's wiring can handle it, but older properties might not love extra load or inverter feedback. If a tenant's setup causes tripped breakers or damage, who's liable? The bill doesn't spell out details on responsibility, so we'd fall back on existing landlord-tenant laws: tenants are generally responsible for damage they cause. Still, disputes could arise over whether a setup violates habitability or quiet enjoyment rules.


For multi-family owners and investors: In larger complexes, widespread adoption could mean balconies dotted with panels—aesthetic concerns for some, but perhaps a selling point as "green" features. Utility billing might shift slightly if enough tenants offset usage, potentially affecting any ratio utility billing systems (RUBS) you use. Investors eyeing energy efficiency upgrades could see this as complementary—small tenant-generated power reduces overall demand on building systems.


For single-family rental providers: Less impact in freestanding homes, as owners already have more solar rights under existing statutes. But for rented houses, tenants could deploy portable systems in yards or on porches, giving them renewable options without permanent fixtures that become your property.


For developers: New builds might need to consider outlet placement or balcony designs that accommodate these devices safely. If portable solar becomes common, it could influence energy modeling or compliance with stretch codes aiming for lower carbon footprints.


Common scenarios and pitfalls:

  • A tenant in a Portland apartment building sets up 800 watts of balcony panels. They plug in, start saving on PG&E or Pacific Power bills. You notice during an inspection—do you allow it or challenge? Under this bill, they likely have the right, as long as under 1,200 watts total.

  • Safety issue: Improper inverter causes outlet damage. Tenant liable, but you handle repairs and potential downtime—document everything and consider adding lease language on approved devices.

  • HOA-managed condo rental: Existing covenants might conflict, but state law could preempt for these small systems.

Best-practice tips, whether this passes or not:

  • Update leases with clear policies on portable renewables—require notification, proof of safe equipment (UL-listed inverters), and indemnification for damage.

  • Educate yourself on safe plug-in solar: Recommend tenants use grid-tied inverters that shut off during outages to protect line workers.

  • Inspect outlets regularly in older buildings—consider upgrades to GFCI or higher-capacity circuits.

  • Market positively: Highlight allowance of portable solar in listings to attract sustainability-minded renters.

  • Partner with utilities: Some offer rebates or guidance on small solar interconnections.


This proposal aligns with broader pushes for renewable energy access, especially in rentals where traditional rooftop solar isn't feasible. Portable systems democratize solar a bit—tenants take them when they move, no stranded investment. In a state like Oregon with ambitious clean energy goals, small steps like this add up. That said, the 1,200-watt limit keeps it modest; we're not talking massive offsets here.


Related subtopics: Ties into existing solar access laws (ORS 105.880 et seq.), which protect solar rights but focus more on permanent installations and shading. Utility regulations from the Public Utility Commission might evolve if usage grows. Nationally, similar "plug-in solar" laws exist in a handful of states, often capping at lower wattages.


The bill is brand new, so details could shift—perhaps adding safety standards, utility notification requirements, or explicit landlord protections.

Call to Action Now's the time to weigh in while it's early.
