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.

- Sunshare: Northern CA. Subscription model ($30-60/month).
- Local utility programs: Check PG&E, SCE, SDG&E websites for pilot programs.
