Net Metering in California
Net Metering 3.0 (NEM 3.0)
California's net metering rules changed on April 14, 2023. Customers who installed systems before April 14, 2023 stay on favorable net metering rates. New systems fall under NEM 3.0, which offers lower per-kWh credits.
| Utility | Service Area | NEM Credit Rate (2026) |
|---|---|---|
| PG&E | Northern/Central CA | ~$0.082/kWh (varies by rate schedule) |
| SCE | Southern CA | ~$0.078/kWh (varies by rate schedule) |
| SDG&E | San Diego | ~$0.084/kWh (varies by rate schedule) |
Pro tip: If you own a home and can install before rates become less favorable, lock in grandfathered rates.
Plug-and-Play Solar Laws in California
California allows renters and balcony owners to install solar devices up to 2 kW without landlord permission under Assembly Bill 1447 (effective Jan 1, 2023).
Key Rules:
- Maximum 2 kW nameplate capacity
- Must be on your exclusive-use space (balcony, patio, deck)
- Must have interconnection approval from utility (typically automatic)
- Landlord cannot charge extra rent or deposit for the device
- Renter must remove device and restore space at lease end
Best for renters: Portable 400-800W balcony solar kits from Amazon, EcoFlow, or Renogy.
HOA Rules in California
California's solar access rights law (CC&R) protects homeowners' right to install solar despite HOA restrictions—but HOAs can still regulate aesthetics.
What HOAs Can't Do:
- Prohibit solar installation altogether
- Charge unreasonable approval fees
- Require non-glare roofing when standard options exist
What HOAs Can Require:
- System design that minimizes visual impact (e.g., rear-roof placement)
- Professional installation and permitting
- Reasonable design review (max 45 days)
Strategy: If your HOA denies solar, contact the CA Energy Commission for dispute resolution.
Community Solar Programs in California
If you can't install on your own property (renter, no roof space, shade), community solar lets you buy shares of a shared solar garden.
Programs:
- Sunrun Community Solar: Bay Area, LA, San Diego. Typical savings 5-15% on electricity.
- Sunshare: Northern CA. Subscription model ($30-60/month).
- Local utility programs: Check PG&E, SCE, SDG&E websites for pilot programs.

Frequently Asked Questions
❓ Can I install solar as a renter in California?
Yes! Under Assembly Bill 1447, you can install up to 2 kW without landlord permission on your exclusive-use space (balcony, patio). No landlord can prohibit it or charge extra rent.
❓ What's the difference between NEM 2.0 and NEM 3.0?
NEM 2.0 (grandfathered): ~$0.30/kWh export rate. NEM 3.0 (new systems after Apr 2023): ~$0.08/kWh. Huge difference! If your home qualifies for NEM 2.0, install ASAP.
❓ Will my HOA block my solar installation?
California law protects your right to solar. HOAs can't prohibit it, but can require reasonable design review. Worst case: place panels on rear roof or use black frames to minimize visibility.
❓ How much will my electricity bill decrease?
Depends on system size and usage. Average: 50-100% reduction. A 6kW system in California typically saves $1,200-2,000/year. Check your current bill to estimate.
❓ Is balcony solar worth it for renters?
Yes if you plan to stay 3+ years. A 400W kit costs $800-1,200 and saves $200-400/year. Payback: 2-6 years. Plus you can take it with you when you move.
❓ What's the federal tax credit timeline?
30% ITC through 2032, then 26% (2033), 22% (2034), then expires. Lock in the 30% rate now if planning to install.
❓ How long do solar panels last?
25-30 years typical. Most warranties cover 25 years at 80%+ output. Inverters last 10-15 years and may need replacement mid-life.
❓ Will solar panels damage my roof?
Professional installation doesn't damage roofs. Installers use flashing + weatherproofing. If replacing your roof, do it before solar. If your roof is old, replace first, then install solar.
❓ Can I go fully off-grid with solar in California?
Yes, but it's expensive. You'd need: large battery bank ($10K+), oversized solar array, backup generator. Grid-tied with battery backup is cheaper ($3-5K extra).
❓ How do I find local solar installers in California?
Search "solar installer near [your city]" on Google, or use Energy.gov's installer locator. Get 3+ quotes before deciding.
