California Solar in 2025 NEM 2.0 vs NEM 3.0 Billing Changes

California’s solar policies have shaped how homeowners save money with renewable energy for more than a decade. For years, Net Energy Metering (NEM) 2.0 allowed solar customers to offset their electric bills with generous credit rates. But in April 2023, California rolled out NEM 3.0, changing how solar owners are credited for excess power sent back to the grid.

Now, in 2025, homeowners are asking: How does NEM 3.0 compare to NEM 2.0—and is solar still worth it? Let’s break down the key differences, what they mean for Southern California homeowners, and how US Power helps you maximize savings.

What Was NEM 2.0?

Under NEM 2.0, homeowners who went solar received nearly full retail credit for every kilowatt-hour (kWh) of electricity they exported to the grid. This meant:

• High savings potential: Bills could be offset by 70–90%.
• Faster payback period: Many solar systems paid for themselves in 5–7 years.
• No urgent need for batteries: The grid acted as a “bank,” storing solar credits for nighttime use.

In short, NEM 2.0 made going solar extremely attractive, but it created challenges for utilities managing high solar adoption.

What Changed with NEM 3.0?

Launched in April 2023, NEM 3.0 drastically reduced the value of solar export credits. On average, credit rates dropped by 75% compared to NEM 2.0. Here’s what homeowners face today:

• Lower export rates: Credits are now closer to wholesale electricity prices.
• Longer payback period: Average ROI now stretches to 8–12 years.
• Stronger case for batteries: Solar alone saves less under NEM 3.0, but pairing solar with battery storage helps homeowners use their power directly instead of selling it back at lower rates.

NEM 2.0 vs NEM 3.0: Key Comparison

Is Solar Still Worth It Under NEM 3.0?

Yes—but the strategy has shifted. While NEM 3.0 reduces export values, homeowners can still unlock big savings by:

1. Installing solar + battery storage to store daytime energy for evening use.
2. Taking advantage of federal tax credits (30% ITC) available through 2032.
3. Using factory-direct panels from US Power’s Qcells partnership for maximum efficiency and long-term performance.

With electricity rates in California continuing to rise—some utilities increasing prices by 5–8% annually—solar remains a smart long-term investment.
