Quick read
- SB 868, the Plug and Play Solar Act by Senator Scott Wiener, was signed September 30, 2026 and takes effect January 1, 2027.
- A certified plug-in solar device up to 1,200 watts per dwelling is exempt from every utility interconnection rule. PG&E can't require approval, charge a fee, or demand extra equipment. It may ask you to register the device online.
- The law says nothing about landlords, leases, HOAs, or CC&Rs. On the Peninsula, that's where the real question sits for most condo owners and renters.
- The exemption expires January 1, 2030 unless the Legislature extends it, a sunset added at the utilities' request.
- A portable device is generally treated as personal property that leaves with the owner.
Rooftop solar in California is hard-wired, permitted, inspected, and connected to the grid through an interconnection agreement with the utility.
SB 868 carves out one small exception. A portable device plugs into an ordinary wall receptacle, stays under 1,200 watts, and carries the right safety certification. That device can now skip the process entirely.
The bill's author, Senator Scott Wiener, represents San Francisco and the northern end of San Mateo County. The Peninsula is squarely in the audience he wrote it for. His office framed it around rising PG&E bills, and around the roughly 40 percent of California households that rent and have no roof to put panels on.
What follows is the law as written and what it leaves untouched. Then, how to think about it if you own a condo in Foster City, rent in downtown San Mateo, or already have a rooftop system in Palo Alto.
Pick the situation closest to yours. Each note is short, and the full detail follows below.
From January 1, 2027, PG&E can't stand between you and a certified device. Your association can, on anything mounted to a railing, patio, or exterior wall it classifies as common area.
If your CC&Rs don't mention plug-in solar, the board decides case by case until it adopts a rule. Ask in writing before you buy, and keep the answer with your closing documents.
The law was written with you in mind, and it removes the utility hurdle completely. It doesn't touch your lease.
A device that sits on a balcony floor and plugs into an interior receptacle is the easiest ask. Anything clamped to a railing or visible from the street may need the owner's written consent. The California Apartment Association registered support for the bill, a fact worth raising when you ask.
If you already have rooftop panels under a net metering or net billing agreement, you have signed an interconnection contract with PG&E that governs generation at your address.
The Senate committee analysis flagged adding a plug-in device on top of a NEM system as a gray area the agreement may not allow. Whether your existing agreement allows a plug-in device is a question for PG&E. Ask in writing before you add one.
Nothing in SB 868 requires you to permit a tenant's device, and nothing prohibits you from allowing one.
The practical move is a short written policy: where a device may sit, what certification it must carry, who is responsible for the receptacle, and what happens at move-out. A tenant who can trim a PG&E bill with a $400 to $2,000 kit has one more reason to renew, and a clear policy keeps the balcony from becoming a dispute.
What Does California's SB 868 Plug-In Solar Law Actually Do?
The statute is narrow on purpose. It adds a short chapter to the Public Utilities Code, starting at section 8530, that defines a "portable solar generation device" and then exempts that device from interconnection. Everything turns on the definition. A qualifying device, or combination of devices:
- Has a maximum aggregated AC output of 1,200 watts per dwelling.
- Is designed to be connected to and disconnected from the building's electrical system through a receptacle.
- Is intended to offset the customer's own onsite electricity use.
- Meets the current National Electrical Code and California Electrical Code.
- Is certified as a plug-in photovoltaic system by Underwriters Laboratories or an equivalent nationally recognized testing laboratory.
- Includes a certified feature that isolates the device from the building's wiring so it cannot backfeed the grid during a power outage.
For a device that meets all six, the utility loses three levers.
It can't require approval before you install or use the device. It can't charge a fee tied to the device or the electricity it feeds into your home. It can't require controls or equipment beyond what is built into the device.
What it may do is ask you to register the device through a simple online form giving the address, make, model, and size. Registering is notice only. It can't be turned into an approval step.
What the law does
- Exempts a certified device up to 1,200 W from all interconnection rules, state and local.
- Bars PG&E and municipal utilities from requiring approval, fees, or extra equipment.
- Allows a simple online registration requirement.
- Sets the safety floor: UL or equivalent certification plus outage shutoff.
- From 2030, bans the sale of plug-in kits that miss that floor.
What the law leaves alone
- HOA rules, CC&Rs, and leases. The bill never mentions them.
- Your existing rooftop interconnection agreement, if you have one.
- Building code: a companion bill, AB 2612, stalled in August.
- Devices that fail the definition. Those stay under the old rules.
How SB 868 Moved From Introduction to Signature
The bill moved through a single session, which for an energy bill opposed by PG&E is quick. The utilities, several IBEW locals, and the National Electrical Contractors Association opposed it on safety grounds.
The sponsor was the Environmental Working Group. Dozens of groups joined in support, including the Abundance Network, the California Solar and Storage Association, Sustainable San Mateo County, and Peninsula Interfaith Climate Action.
- January 5, 2026Senator Wiener introduces SB 868, the Plug and Play Solar Act.
- March 17, 2026Senate Energy, Utilities and Communications Committee hearing. Staff recommend a utility registration option and a reference to the National Electrical Code. Both end up in the bill.
- May 19, 2026Senate passes the bill 35 to 1.
- June 10, 2026Assembly Utilities and Energy Committee hearing. Staff ask for the 1,200 W cap to read per dwelling and for make-and-model registration. Both end up in the bill.
- August 2026Assembly Appropriations adds the January 1, 2030 sunset on the interconnection exemption, language the utilities sought. The Assembly passes the bill August 25, and the Senate concurs 36 to 4 on August 26.
- September 30, 2026Governor Newsom signs SB 868 on the last day to act on the session's bills.
- January 1, 2027The law takes effect. Certified devices need no utility approval from this date.
- January 1, 2030The exemption and the no-approval rule expire unless the Legislature extends them. From the same date, a plug-in kit without the required code compliance and UL certification can no longer be sold in California.
Because plug-in systems are small and portable, they expand the solar market, especially to renters, condo owners, and people with balconies, small backyards, or patios.Senator Scott Wiener, author's statement, Assembly committee analysis, June 10, 2026
What a Plug-In Solar Kit Costs and What It Can Save on a PG&E Bill
The numbers below come from the bill's sponsors and the legislative analyses, so read them as the sponsors' case for the bill.
The committee staff made the same point: when they wrote their analysis, no complete kit on the market had yet earned the full UL system certification the law requires. The first certified kits are expected to follow the market the law creates.
| Figure | What was reported | Source |
|---|---|---|
| 200 W kit, no battery | About $400 | Senator Wiener's office |
| 800 W kit, no battery | Up to $2,000 | Senator Wiener's office |
| Share of a home's electricity | 14 to 20 percent, proponents' estimate | Senate committee analysis |
| Annual savings, small apartment | $400 to $500, proponents' estimate | Senate committee analysis |
| Average California home use | 6,000 to 8,000 kWh a year, apartments at the low end | Senate committee analysis |
| PG&E average residential rate | 40.60 cents per kWh, bundled non-CARE, effective March 1, 2026 | PG&E rate advisory |
One detail matters more than the headline savings. A plug-in device offsets what you use while the sun is up. There is no net metering credit for a plug-in kit, and the law doesn't create one.
A household that runs its dishwasher, laundry, and EV charger in the evening will see less benefit. One whose daytime load is a refrigerator, a home office, and a window air conditioner in a Redwood Shores summer will see more. The 1,200-watt ceiling is the point. The Assembly committee estimated average household demand at roughly 700 watts, so the cap is sized to cover daytime use with little left over to export.
Seven Questions to Answer Before You Plug In
Copy this list and work it from the top. Most of the questions have nothing to do with the utility, which is exactly why the law alone doesn't settle them.
Who controls the surface you want to mount on?
Balcony railings, patios, and exterior walls in a Peninsula condo are usually common area or exclusive-use common area under the CC&Rs, which puts them under the board.
A single-family lot in Burlingame is yours. A rental is the owner's. Settle this first, in writing.
Does the kit carry full system certification?
The law requires the whole plug-in photovoltaic system to be certified by UL or an equivalent lab, with a certified outage shutoff. Ask the seller for the system-level certification by name, and confirm it with the testing lab.
Do you already have an interconnection agreement?
Rooftop solar owners under NEM 2.0 or the current net billing tariff have a contract with PG&E. The Senate analysis called stacking a plug-in device on top of it a gray area. Ask PG&E in writing before you buy.
Which circuit will it share?
The device feeds the branch circuit it plugs into. The safety debate in Sacramento centered on overload risk when generation and a heavy appliance share one 15-amp circuit.
A receptacle that serves a refrigerator and a space heater is a poor choice. A licensed electrician can tell you which receptacle in an older Peninsula home can take the load.
What does your daytime load look like?
Pull a year of PG&E interval data from your account. If most of your use lands after 6 p.m., a 1,200-watt device with no battery will offset less than the sponsors' range suggests. The savings figures assume a daytime load to absorb the output.
Will PG&E ask you to register it?
The law lets a utility require a simple online registration giving the address, make, model, and size of the device. PG&E has not yet said whether it will require registration. Registering is the one obligation the law leaves on your side.
What is your plan for 2030?
The exemption is scheduled to expire January 1, 2030. The Legislature may extend it. Uncertified kits can't be sold in California from that date, so a certified kit is the one that ages well.
Whether a kit pays for itself before 2030 depends on its cost and your daytime use. Run your own numbers against your PG&E bill.
Does SB 868 Change What a Peninsula Home Is Worth?
By itself, no. A portable device is generally treated as personal property that leaves with the owner.
It's closer to an appliance than to a rooftop system. Ask your county assessor and your agent how a specific device would be handled.
What the law may change, slowly, is the conversation around condo and townhome ownership on the Peninsula. A buyer looking at a two-bedroom in Foster City or a townhome in Redwood Shores has never had a solar option.
From 2027 there is one, and a board that has written a clear balcony policy will be easier to sell into than one that hasn't. Expect "what's the HOA's position on plug-in solar" to join "what are the dues" on the list of questions a careful buyer asks. The HOA cost estimator covers the dues side; the solar side is a question for the board.
For single-family owners, the calculus is unchanged. A permanent rooftop system with a battery, documented and transferred with the home, is part of the home's energy picture in a sale. A plug-in kit is a bill tool for the years you live there.
What SB 868 Does Not Settle, and Why It Matters More Here
Three gaps remain open.
HOAs and leases. The statute governs the utility relationship and nothing else. California's solar rights law limits unreasonable HOA restrictions on solar energy systems. Whether a movable device clamped to a balcony railing falls inside that protection hasn't been tested, and the Legislature didn't address it in SB 868.
For now, the CC&Rs and the board's rules govern. Expect case-by-case answers from any board that hasn't adopted a policy.
Building code. A companion bill, AB 2612, would have directed the Building Standards Commission to adopt standards for electrical circuit features that let plug-in solar work safely in new construction. Its author, Assembly Member Schultz, is also SB 868's principal coauthor. It stalled in the Senate in August and will need to be reintroduced. Until then, a device plugs into the receptacle you have, and the overload questions the IBEW raised are yours to manage.
The sunset. The 2030 expiration applies to the interconnection exemption and the no-approval rule. The sales ban on uncertified kits that starts the same day has no end date. If it lapses, a device bought in 2027 would fall back under whatever rules the CPUC adopts for these devices in the meantime. The CPUC has already opened a proceeding, R.25-08-004, that asks whether plug-in solar belongs under Rule 21, its interconnection tariff, so the ground won't be empty in 2030.
Already have rooftop solar and thinking about selling in the next year? How the system, the battery, and the net metering agreement transfer belongs in the pricing conversation before you list. Lisa's Page One shows a seller where the home sits inside this month's numbers before anything is listed.
What this means for you
If you own a single-family home, SB 868 changes little. Your rooftop options were already open, and a plug-in kit is a small supplement at most.
If you own a condo or townhome, or you rent, the utility door opens January 1, 2027, and the HOA or lease door is the one to knock on now. Ask the question in writing this fall, so you have an answer before the first certified kits ship.
If you're buying into an association in 2027, add the board's plug-in solar position to your due diligence list. A written policy, either way, is a sign of a board that reads the mail. Talk with Lisa about the HOA questions to raise before you write an offer.
Frequently Asked Questions
What does California's SB 868 plug-in solar law actually do?
SB 868 exempts a defined portable solar generation device from every interconnection requirement imposed by state law, the CPUC, PG&E, or a municipal utility. A qualifying device connects to the home's wiring through a receptacle, has a maximum aggregated AC output of 1,200 watts per dwelling, is certified as a plug-in photovoltaic system by UL or an equivalent lab, and includes a certified feature that stops it from backfeeding the grid during an outage.
The utility can't require its approval, charge a fee, or demand extra equipment. It may ask you to register the device through a simple online form. Governor Newsom signed the bill on September 30, 2026, and it takes effect January 1, 2027.
Does SB 868 override my HOA rules or my lease?
No. SB 868 governs the relationship between you and your electric utility. It doesn't mention landlords, leases, homeowners associations, or CC&Rs. A condo owner in Foster City or a renter in San Mateo still answers to the governing documents or lease on anything mounted to a balcony railing or visible from the street.
California's existing solar rights statute limits unreasonable HOA restrictions on solar energy systems, but whether a plug-in device on a railing falls inside that protection hasn't been tested. Read the documents, and ask before you buy.
When can I legally plug in a balcony solar kit in California?
The law takes effect January 1, 2027. The interconnection exemption and the no-approval rule are scheduled to expire January 1, 2030 unless the Legislature extends them, a sunset the Assembly added in August 2026 at the utilities' request.
How much does a plug-in solar kit cost and what can it save on a PG&E bill?
Senator Wiener's office cited roughly $400 for a 200-watt kit without a battery and up to $2,000 for an 800-watt kit. The Senate committee analysis reported proponents' estimate that a kit can meet 14 to 20 percent of a home's electricity needs and save $400 to $500 a year for a small apartment.
Those are the sponsors' figures, and the committee flagged that no complete kit had yet earned full UL system certification when it wrote the analysis. Treat the savings as a range to test against your own bill, which PG&E reported averaging 40.60 cents per kilowatt-hour for bundled residential customers as of March 1, 2026.
Does a plug-in solar device change what a Peninsula home is worth?
By itself, no. A portable device is generally treated as personal property that leaves with the owner. Ask your county assessor and your agent how a specific device would be handled.
What matters in a sale is the home's documented energy picture: an existing rooftop system and its net metering status, a battery, panel capacity, and whether the HOA has written rules on balconies. A plug-in kit is a bill tool for the years you live there, and it can be a useful one for a condo owner or renter who could never put panels on a roof.
