California Copies Germany’s Balcony Solar With a 2030 Sunset

Governor Gavin Newsom signed California’s balcony solar law on September 30, capping plug-in kits at 1,200 watts per home. The Plug and Play Solar Act, written by state Sen. Scott Wiener, lets a certified device feed a standard outlet without a utility interconnection agreement.

Germany already runs this as a mass product, with 1.5 million systems on the books. California is the 10th U.S. state to sign a dedicated plug-in law, and the easy utility rules expire on January 1, 2030.

What a 1,200-Watt Plug-In System Can Power

SB 868, now Chapter 985 of the Statutes of 2026, treats a qualifying kit more like an appliance than a power plant. The device, or several of them added together, must stay at or under 1,200 watts of AC output per dwelling. It has to plug into a receptacle, meet the National Electrical Code and the California Electrical Code, and shut itself off if the grid dies, so it cannot energize a dead line.

Wiener, in the bill analysis submitted under his name, said the act “will give renters and homeowners a simple, low-cost tool to reduce their energy bills and reduce pollution.” The Environmental Working Group and the Abundance Network sponsored the measure. It does not create a rebate, a tariff, or a credit for leftover watts. Power you do not use while the sun is up is worth nothing to the account.

THE 1,200-WATT CAPSULE

• The cap: Combined AC output may not exceed 1,200 watts per dwelling, so stacking extra kits does not reset the limit.
• The price band: Solar United Neighbors puts typical plug-in kits between $400 and $2,000, with or without a small battery.
• The rooftop gap: A common home array runs 3,000 to 9,000 watts, which is why a balcony kit covers a fridge and lights, not the whole house.

That group’s payback estimate is about five years, and only on electricity the household actually consumes in real time. Midday solar is already plentiful on California’s grid, so extra balcony watts mostly shrink the owner’s bill in sunny hours rather than filling a system shortage. For a renter paying steep peak rates, that household math can still hold even when the grid does not need another noon panel.

Germany Already Has 1.5 Million of These

Paul Gipe, writing up an annual count by analyst Alexander Jacob, reported on September 22 that registered German balcony systems had topped 1.5 million. The fleet can make more than one terawatt-hour a year, about 1.1 percent of the solar electricity Germany produces.

Berlin got there by shrinking the paperwork, not by inventing a new panel. Solarpaket I, in force since May 16, 2024, lifted the inverter cap from 600 watts to 800 watts and set module capacity at 2,000 watt-peak. Registration is a single free filing in the federal Marktstammdatenregister within a month. The local grid operator is copied automatically and cannot stall a qualifying kit. Since October 2024, German tenants have also had a civil-law claim to install, and a landlord may refuse only for important reasons.

HOW THE RULES COMPARE

Utah was first in the United States. Colorado later set a higher mark, at 1,920 watts. California’s AC number beats Germany’s inverter cap on paper. The German package is the one that already turned into a consumer product, with a tenant right and no 2030 fuse.

Utilities Forced a 2030 Expiration Date

The Assembly did not just tidy the safety language. It added a clock that investor-owned utilities had asked for, including San Diego Gas & Electric and its parent Sempra. The sunset on the interconnection exemption is January 1, 2030, unless lawmakers extend it. After that date, a utility can again demand a full interconnection file, advance approval, and device fees.

The same deadline has a second edge. Beginning January 1, 2030, it becomes illegal to sell a plug-in photovoltaic device in California that uses a receptacle and fails the bill’s definition. Safety certification and the 1,200-watt cap remain as a product rule even if the easy interconnection path dies. Pacific Gas & Electric fought the bill on reliability and cost-shift grounds. Southern California Edison dropped its fight after the text was changed to let utilities confirm certification.

HOW SB 868 BECAME LAW

1. May 19, 2026: The Senate passes the bill 35 to 1.
2. August 25, 2026: The Assembly passes it 73 to 0, with the 2030 sunset in the text.
3. August 26, 2026: The Senate concurs in those amendments, 36 to 4.
4. September 30, 2026: Newsom signs. The measure is chaptered as Chapter 985. With no urgency clause, it takes effect January 1, 2027.

Utilities may still require a simple online notice listing the address, make, model, and size. They may not charge a device fee, demand extra hardware beyond what is built into a certified kit, or make the customer wait for permission to operate. That bargain holds for three years after the law goes live.

Landlords and Fire Codes Remain in Charge

The enrolled digest never grants tenants a right to mount a panel. It binds electrical corporations and publicly owned utilities. It does not rewrite a lease, a CC&R, or a fire code. The Southern California Rental Housing Association opposed the bill on the ground that generating gear could be added without notice to the owner, and without a check that the building’s wiring or the lease could take it.

California’s Solar Rights Act still stops a homeowners association from banning rooftop solar, and it caps “reasonable” HOA conditions at $1,000 of extra cost or a 10 percent output cut, with a 45-day clock. Those Civil Code tests were written around roof systems, not a railing kit on a shared-wall balcony. An HOA that cannot outlaw rooftop panels can still police clutter, color, and cable runs on a balcony. A lease that bars fixtures can still bar fixtures.

City rules on balcony obstructions and egress also survive. Those codes differ across Los Angeles, San Diego, and San Jose. A renter who plugs in without looking at the lease and the fire exit path is betting the new statute covers a fight it never mentions.

Certified Kits Have Not Reached Store Shelves

Qualifying devices must be certified as plug-in photovoltaic systems by Underwriters Laboratories or an equivalent nationally recognized testing laboratory, with a listed feature that isolates the kit in an outage. UL published UL 3700 certification criteria on December 11, 2025. Solar United Neighbors, writing with Bright Saver on September 3, said no plug-in system in the United States had yet received UL or other NRTL certification.

That gap is why a September 30 signature does not put a legal kit on a balcony this fall. The statute itself waits until January 1, 2027. Manufacturers still have to finish the lab queue. Until a listed product exists, the interconnection holiday is a rule without a device that can use it.

WHAT STILL BLOCKS A PLUG-IN KIT

• The lab: No U.S. plug-in kit had UL or equivalent certification as of early September, so retailers have nothing that meets the statute’s test.
• The calendar: The law takes effect January 1, 2027, because it carries no urgency clause.
• The building: Leases, HOA appearance rules, and local fire and egress codes are outside the utility exemption.
• The meter: There is no export payment, and the kit must go dark in a blackout, so it is not backup power.

People already bought gray-market porch panels while the rules were unsettled. Those units do not become legal appliances until they match the definition, including the isolation feature. A battery packed with a kit is a separate product, and it is the battery, not SB 868, that can keep a fridge running when the feeder fails.

Two Other Bills Target the 89 Percent Rate Jump

Newsom signed two Josh Becker bills the same day, aimed at the wires and at gear Californians already own. The Climate Center, co-sponsor of SB 913, notes that rates for customers of Southern California Edison, San Diego Gas & Electric, and Pacific Gas & Electric have risen an average of 89 percent over the last decade, citing the Public Advocates Office. Kat Lockwood, the group’s CEO, said the new laws offer bill relief and a foundation the next governor can use.

Californians have already invested in millions of batteries, electric vehicles, smart thermostats, and other technologies that can help keep our grid reliable. We should be putting them to work. Instead of simply building more expensive infrastructure and passing those costs on to ratepayers, SB 913 helps us get more out of resources Californians have already paid for.

Josh Becker, state senator, D-Menlo Park, statement on the Clean Local Power Act

SB 913, the Clean Local Power Act, tells the California Public Utilities Commission to fix the path so coordinated home batteries, EVs, and thermostats can count toward Resource Adequacy, the obligation to have power on hand when customers need it. Regulators have until June 30, 2028. Becker’s office, citing the commission, says installers are adding more than 8,000 customer batteries each month, totaling over 100 megawatts, enough in that framing to replace a peaker plant on a monthly cadence. The state’s Demand Side Grid Support program has already unlocked more than 1,000 megawatts from customer devices. Electricity demand is projected to grow by as much as 61 percent over the next two decades.

SB 905 pushes the large investor-owned utilities to publish how heavily local circuits are used, how much room they have off-peak, and where capacity is tight. They must also test whether batteries or load-shifting could meet a local need more cheaply than a traditional upgrade. The commission is to consider lower shareholder returns on some investments and cheaper ways to finance wires, and to report to the Legislature by December 31, 2028. The savings, if any, depend on those later rulings, not on the signing photo.

The balcony kit is the part of the package a renter can picture. The Becker bills are the part that has to move money inside the Resource Adequacy market and the capital budget for poles. On January 1, 2027, the outlet becomes legal for a listed 1,200-watt device. On January 1, 2030, the easy interconnection rules expire unless the Legislature votes again.

Frequently Asked Questions

When Does California’s Balcony Solar Law Take Effect?

January 1, 2027. California bills without an urgency clause wait until the next January 1, so a September 30 signature still leaves the fall of 2026 under the old interconnection rules. Until that date, a plug-in kit is still treated as grid-tied generation that needs utility permission.

Can a Landlord or HOA Block a Plug-In Kit?

Yes, in practice, because SB 868 never created a tenant installation right. German civil law did that in 2024; this statute did not copy that chapter. An HOA can still enforce balcony appearance and cable rules, and the Solar Rights Act’s $1,000 and 10 percent tests were written for rooftop systems, not railing mounts.

Does Balcony Solar Keep Working in a Blackout?

No. A qualifying device must include a certified isolation feature that cuts it off when the grid goes down, so lineworkers are not fed from a balcony. Anyone who wants a running fridge during an outage needs a battery product, which is outside this exemption.

What Is UL 3700 and Why Does It Matter?

UL 3700 is the U.S. evaluation framework for interactive plug-in photovoltaic equipment, released on December 11, 2025. SB 868 only exempts devices certified by UL or an equivalent nationally recognized testing laboratory, so a kit without that mark cannot use the new interconnection holiday even after January 1, 2027.
