As of June 2026, California does not have a dedicated plug-in solar law. SB 868 — the "Plug and Play Solar Act" — passed both chambers of the California Legislature in June 2026 and is sitting on Governor Newsom's desk. Until he signs it, the legal landscape for balcony and plug-in solar in California is a gray area governed by existing utility rules and the California Solar Rights Act.
Here's what's actually legal right now, what changes when SB 868 is signed, and what the honest caveats are.
Where Things Stand: SB 868 Is Not Yet Law
Bill: SB 868 (Senator Scott Wiener, D-San Francisco) Title: "Plug and Play Solar Act" Status: Passed Senate and Assembly; pending Governor's signature as of June 2026 What it would do: Exempt plug-in solar devices from all CPUC interconnection rules (including Rule 21), from utility interconnection agreements, and from net metering eligibility requirements. Devices would be classified as appliances, not power generation facilities. Wattage limit proposed: Not a single hard cap — the bill defers to UL 3700 or equivalent NRTL certification as the qualifying criterion.
Until SB 868 is signed, none of these exemptions apply.
What Governs Plug-In Solar in California Right Now
NEC 705.12 (the 120% rule) is the de facto federal floor. For any grid-tied solar connection — including plug-in systems — the sum of 125% of the inverter's AC output current plus the main breaker rating cannot exceed 120% of the busbar's rated ampacity. For a standard 200A panel with a 200A main breaker, this limits inverter-connected solar to roughly 40A AC output, or about 4,800W at 120V. A typical 600–800W plug-in system is well within this limit.
California Electrical Code (CEC) follows NEC with state amendments. PG&E, SCE, and SDG&E each apply their own interconnection tariffs (Rule 21 for investor-owned utilities) on top of the CEC. Rule 21 is what SB 868 is trying to exempt plug-in solar from.
CPUC Rule 21 currently applies to all solar systems that interconnect with the grid — including plug-in units. PG&E interprets this as requiring registration for any system that can export power. The registration process costs $100–$800 and typically takes three business days. SDG&E and SCE have similar positions.
Zero-export systems — which throttle output to prevent any backfeed — occupy a genuine gray area. Utilities have not officially ruled that zero-export plug-in systems require interconnection agreements, but they have not explicitly exempted them either.
What California Civil Code §714 Does (and Doesn't) Cover
California Civil Code §714, the core of the California Solar Rights Act, voids any HOA restriction that "effectively prohibits or restricts the installation or use of a solar energy system." An HOA restriction is only permissible if it doesn't increase costs by more than $1,000 (or $2,000 for systems over 10kW) or reduce efficiency by more than 10%.
What this means for balcony solar:
Section 714 was written primarily for rooftop systems on single-family homes. Its applicability to balcony or plug-in solar on condominiums is legally untested. The issue is that condo balconies are typically "limited common elements" — you have exclusive use rights, but the HOA retains some authority over structural and aesthetic modifications.
Courts have not definitively ruled on whether §714 protects a plug-in solar installation on a condo balcony. What is clear:
- For single-family homeowners with an HOA, §714 provides strong protection. An HOA cannot deny a reasonably placed plug-in solar installation that meets the cost and efficiency thresholds.
- For condo owners, the legal footing is shakier. An HOA can argue the balcony is common element and subject to board approval on safety and structural grounds.
- For renters, §714 does not apply. It protects property owners from HOA restrictions, not tenants from landlords.
HOAs must process solar applications within 45 days or the application is deemed automatically approved. This timeline protection applies regardless of the system type.
LA vs. SF: Utility Positions Differ
PG&E (Bay Area, Central Valley): Requires registration for all solar systems that can export. Zero-export plug-in systems are in a gray area — no documented enforcement against residential users, but no formal exemption either. Registration costs $100–$800 and takes roughly three business days.
LADWP (Los Angeles): Has not issued formal guidance specific to plug-in solar. LADWP is a municipal utility and is not subject to CPUC Rule 21, which means it sets its own interconnection rules. As of mid-2026, LADWP has not announced a simplified pathway for plug-in systems.
SDG&E (San Diego): Follows CPUC Rule 21 similarly to PG&E. No specific plug-in solar guidance published.
The lack of uniform utility guidance is exactly what SB 868 is designed to fix by removing interconnection requirements for qualifying devices entirely.
When SB 868 Is Signed: What Changes
If Governor Newsom signs SB 868, California plug-in solar users would:
- Not need a utility interconnection agreement for qualifying devices
- Not need to register with PG&E, SCE, or SDG&E before installing
- Not be subject to CPUC Rule 21 for these systems
- Not be eligible for net metering — the exemption cuts both ways; you get the simplicity, but not the grid credit program
The bill does not specify a hard wattage cap. Instead, it requires devices to meet UL 3700 or equivalent NRTL certification. Since no products have achieved UL 3700 certification yet (as of mid-2026), the practical effect of a signed SB 868 would initially be limited to systems with UL 1741-certified microinverters, pending manufacturer certification to the new standard.
The Honest Caveat: California Is Still Waiting
California has 14 million rental units — more than any other state. The case for plug-in solar access is straightforward. But as of June 2026, the law isn't signed, the dominant utilities require registration, the HOA protections for condo balconies are legally ambiguous, and zero certified UL 3700 products exist.
The practical state of play for a California renter or condo owner right now:
- Single-family homeowner with HOA: §714 likely protects you. Get a UL 1741-listed microinverter system. Register with your utility if it's PG&E or SDG&E territory.
- Condo owner: Your legal footing under §714 is uncertain. Get board approval in writing before installing.
- Renter: §714 does not protect you. Get explicit written permission from your landlord. A zero-export system with a UL 1741 microinverter is the safest argument for minimal grid impact.
