Plug-in Solar in California: SB 868 and What It Means for You

California Is About to Legalize Balcony Solar—And It's a Big Deal

California's SB 868, the "Plug Into the Sun Act," passed committee with a 12-0 vote in early 2026. It's expected to pass the full legislature and get signed into law within weeks of April 2026.

When it does, California will become the second state (after Utah) to explicitly legalize plug-in solar. But SB 868 goes much further than Utah's law. It reclassifies plug-in solar as an appliance, not a permanent installation. It protects renters. It explicitly overrides HOA restrictions. And it sets the precedent for how future national policy might work.

If you're in California and you've been waiting for clarity on whether you can go solar as a renter or in an HOA-controlled property, SB 868 is the green light you've been waiting for.

What SB 868 Actually Says

The bill authorizes plug-in solar systems up to 400 to 1,200 watts (depending on circuit capacity) and classifies them as portable electrical appliances, not permanent structures.

Here's why that distinction matters: permanent structures require HOA approval and might violate your lease. Appliances usually don't. By classifying plug-in solar as an appliance, the law sidesteps HOA restrictions that would apply to, say, installing a permanent rooftop system.

SB 868 also explicitly states that landlords cannot prohibit tenants from installing balcony solar. Renters in California will have a legal right to portable solar that most other Americans don't yet have.

The bill requires that systems be UL 3700-certified when products are available (which should be by late 2026). Until then, systems can be installed if they meet applicable safety standards.

The California Electricity Context: Why SB 868 Matters Economically

California's electricity rates are among the highest in the nation: roughly $0.29 to $0.31 per kWh for most residential customers. This is nearly double the US average of $0.17.

A 1,200-watt plug-in system in California generates about 1,200 to 1,400 kWh per year (California has 5 to 5.5 peak sun hours on average, varying by region). At California rates, that's about $350 to $430 per year in electricity value.

A $1,200 system pays for itself in 3 to 4 years in California. That's a compelling financial case. And with the federal 30 percent investment tax credit, your actual cost drops to $840, and payback shrinks to 2 to 3 years.

This is why SB 868 is expected to drive rapid adoption in California.

NEM 3.0: The Catch in California's Net Metering

California's net metering rules changed in January 2023 with NEM 3.0. And they're less favorable than the old rules.

Under NEM 3.0, the credit you receive for pushing solar power back to the grid is lower than the rate you pay for pulling power from the grid. The difference is about $0.02 to $0.04 per kWh. In other words, you get less credit for solar exports than you pay for imports.

This changes the financial equation slightly. Instead of getting a full $1.70 credit per kWh, you might get $1.40 to $1.50. It still works out, but it's not as generous as the old NEM 2.0 rules.

For plug-in solar specifically, NEM 3.0 means you're still financially viable, but the payback timeline is maybe 3.5 to 4.5 years instead of 2.5 to 3.5.

However, plug-in solar is small enough that it might not trigger NEM 3.0's most aggressive policies if you're just offsetting 10 to 20 percent of your usage. Check with your utility to see how they apply NEM 3.0 to small systems.

California Solar Rights Act and HOA Protections

California's Solar Rights Act has protected rooftop solar owners' rights against HOA restrictions for years. But it was written for permanent structures.

SB 868 extends similar protections to balcony solar by classifying it as an appliance. This is huge for renters and HOA residents. Your HOA can't ban you from having a solar panel on your balcony if it's portable and plugs into an outlet.

That said, your HOA might still enforce balcony appearance rules (clutter, specific colors, etc.). But they can't single out solar for prohibition.

For renters, this means a landlord can't prohibit balcony solar under SB 868. Before SB 868, a landlord could cite lease restrictions on exterior modifications. After the law passes, that restriction wouldn't apply to portable appliances.

Regional Sunshine in California

California's sun varies significantly by region, but most of the state averages 5 to 5.5 peak sun hours per day.

Northern California (San Francisco Bay Area, Sacramento) averages 4.5 to 5 peak sun hours—good but not exceptional due to marine layer fog in summer.

Southern California (Los Angeles, San Diego, inland regions) averages 5.5 to 6 peak sun hours—excellent for solar.

The Central Valley (Fresno, Bakersfield) averages 5.5 peak sun hours.

Coastal areas can have lower averages due to fog, while inland and desert regions (Palm Springs, Death Valley region) can exceed 6 peak sun hours in summer.

To estimate your system's output, multiply your location's peak sun hours by your system's wattage. A 1,000-watt system in a 5 peak sun hour location generates about 5,000 watt-hours (5 kWh) per day on average, or 1,825 kWh per year.

Available Products and Where to Buy in California

As of April 2026, plug-in solar products aren't yet UL 3700-certified, but several manufacturers are in testing.

EcoFlow currently sells plug-in systems in Utah and is expected to expand to California. Craftstrom, which has sold around 4,000 systems in 35 states, is also expected in California. Bright Saver, which operates in the Bay Area and LA, is a regional option.

Once SB 868 passes and UL 3700-certified products arrive (expected mid-to-late 2026), expect a flood of options from both established solar companies and new entrants.

We'll have detailed product reviews on Pluggedin.solar once certified systems are available. For now, watch for UL 3700 certifications arriving.

Apartment Living: The Renter Case Is Strongest in California

California has 6.5 million renters. Many live in dense urban areas (San Francisco, LA, San Diego) where rooftop solar is impossible. SB 868 is transforming solar from off-limits to accessible for this huge population.

A renter in a San Francisco apartment with a south-facing balcony could install a 600-watt system for $600 to $800, generate $150 to $200 per year in electricity value, and take it when they move. Over a 20-year renting career, moving every 3 to 5 years, a renter could install multiple systems and gradually build a solar asset that follows them through life.

This is genuinely revolutionary for renters.

HOA Considerations: What You Can and Can't Do

Under SB 868, your HOA cannot prohibit portable solar on balconies or patios. But they might still enforce rules about:

• Panel color or appearance (if you have a choice of finishes)
• Balcony clutter or organization
• Safety or structural integrity

The key is that the restriction must be about the HOA's legitimate concerns (appearance, safety, structural), not about blocking solar specifically.

If your HOA says "no external structures," a portable panel that doesn't bolt to the building might still be allowed because it's not a permanent structure.

If your HOA says "all balcony items must be white," and your panel comes in black, that's a valid appearance rule that applies to solar and non-solar items equally.

If your HOA says "no solar panels," that's directly prohibited under SB 868, and you can challenge it.

When to Expect Clarity and Availability

As of April 2026:

• SB 868 is expected to pass the legislature within weeks and be signed into law by the governor
• UL 3700-certified products are expected to start arriving in mid-2026
• Full market clarity and multiple product options should exist by late 2026
• Early adopters (now) are buying non-certified products and accepting regulatory risk

We recommend most California residents wait until late 2026 for certified products and full legal clarity. But if you're confident in your situation and have checked with your utility and landlord/HOA, you can proceed now.

The California Advantage

California is becoming the nation's most renter-friendly solar state. SB 868 is doing what federal law hasn't yet done: explicitly guaranteeing renters' rights to renewable energy.

Combined with California's high electricity rates (which make solar economics compelling), 5+ peak sun hours (which makes generation viable), and dense urban housing (which makes rooftop solar impossible), California is the ideal market for plug-in solar.

Within 12 months, we expect California to be a plug-in solar hotspot. Renters will have more options. Prices will likely drop as competition increases. Community norms will shift toward accepting balcony solar as standard equipment, like window air conditioners.
