What the Grid Ready Home Act Means for California’s Solar Future

In 2025, the solar industry introduced the Grid Ready Home Act, a forward-thinking legislative framework designed to modernize how rooftop solar and battery systems are permitted, interconnected, and powered across the U.S.

While California hasn’t yet enacted the Act as law, the state is already taking big steps in that direction—positioning homeowners for faster approvals and a smoother solar installation process. Here’s what this means for Southern California homeowners—and how US Power is already prepared to deliver grid-ready solar systems.

What Is the Grid Ready Home Act?

The Grid Ready Home Act is a model policy developed by the Solar and Storage Industries Institute (SI2) and SEIA in 2025. It aims to:

• Streamline solar and battery permitting
• Standardize grid interconnection timelines
• Encourage smart inverter technology
• Hold utilities accountable for timely processing
• Expand energy affordability and resilience at the household level

In essence, the Act sets a nationwide blueprint for making solar adoption faster, cheaper, and more efficient.

Is California Adopting the Grid Ready Home Act?

As of late 2025, California has not yet formally enacted the Grid Ready Home Act. However, several state policies already align with its goals:

1. SB 379: Residential Solar Permit Reporting

California law now requires most cities and counties to use online automated permit systems (like SolarAPP+) for residential rooftop solar and storage.
Larger cities such as Los Angeles, Anaheim, and Pasadena have already adopted these platforms, reducing approval times from weeks to just a few days.

2. Modernized Interconnection Processes

Utilities like SCE, LADWP, and SDG&E are actively upgrading their Rule 21 interconnection systems to handle more solar capacity, preparing for grid-ready integration standards.

3. Smart Inverter and Grid Code Compliance

The California Energy Commission (CEC) continues to expand smart inverter requirements—one of the Act’s main pillars—ensuring seamless power flow and grid stability as more homes go solar.

In short, California is already implementing many of the same features, even if the full “Grid Ready Home Act” hasn’t officially passed yet.

What Homeowners Can Expect in Major Southern California Cities

Here’s what typical solar permitting and interconnection timelines look like as of 2025:

These cities are already moving toward grid-ready standards, with faster online permitting and digital interconnection workflows—a clear signal that California is preparing for statewide adoption.

What This Means for Southern California Homeowners in 2025

The Grid Ready Home Act may not be law yet, but its impact is already here.
