How Net Metering Changes Affect California Homeowners
California’s solar landscape has changed significantly in recent years, and one of the biggest developments impacting homeowners is the shift in how utilities compensate solar customers for excess power sent back to the grid.
If you’re considering solar or exploring energy-saving options, understanding how net metering works—and how recent changes affect your potential savings—is essential before making any long-term decisions.
What Is Net Metering?
Net metering is a billing system that allows homeowners with solar panels to receive credit for excess electricity their system generates and exports back to the utility grid.
Here’s a simplified breakdown of how it works:
Your solar panels generate electricity during daylight hours
Your home uses that electricity first
Excess production is sent to the grid
Your utility issues credits for the exported power
Historically, California’s net metering policies made solar highly attractive because homeowners often received credits close to the retail electricity rate.
What Changed in California?
California has transitioned many new solar customers to an updated compensation structure commonly referred to as NEM 3.0, or the Net Billing Tariff.
Under the new structure:
Exported solar energy is compensated at significantly lower rates than under previous net metering programs
Solar savings rely more heavily on using your power directly rather than exporting it
Battery storage has become more valuable for maximizing savings
These changes were implemented by the California Public Utilities Commission for most customers of the state’s major investor-owned utilities.
Important Note for LADWP Customers
These net metering changes do not apply to homeowners served by Los Angeles Department of Water and Power under the state’s NEM 3.0 structure.
That’s because LADWP operates its own solar and energy export programs independently from the California Public Utilities Commission’s investor-owned utility regulations.
As a result:
LADWP customers follow different solar compensation rules
Export rates and program structures may differ from SCE, PG&E, and SDG&E
Solar economics can vary significantly depending on your utility provider
Because of this, homeowners should always evaluate solar opportunities based on the policies of their specific utility.
Why Did California Change Net Metering?
State regulators cited several reasons for the transition:
Grid Cost Allocation
Officials argued prior net metering programs shifted certain grid maintenance costs onto non-solar customers.
Lower Midday Energy Value
As solar adoption increased, excess daytime solar production became less valuable to the grid during certain hours.
Push Toward Energy Storage
The new structure encourages battery adoption and smarter energy management.
How These Changes Affect Homeowners Considering Solar
Solar Can Still Reduce Bills
While export credits are lower, solar can still provide substantial savings for many homeowners.
Battery Storage Is More Valuable Than Before
Storing excess daytime production for evening use can improve system economics significantly.
Proper System Design Matters More
Oversized systems that export large amounts of power may deliver lower returns than they did under older net metering rules.
Existing Solar Customers May Be Grandfathered In
Homeowners who installed solar under earlier net metering programs may remain on their previous tariff for a grandfathering period, depending on utility and enrollment date.
This means some existing solar customers may continue receiving more favorable export compensation than new applicants.
Program details vary by provider and installation timeline.
Should Homeowners Still Consider Solar?
For many California homeowners, solar can still make financial sense—but the strategy has changed.
Today, the best results often come from:
Designing systems around actual usage needs
Maximizing self-consumption of generated energy
Pairing solar with battery storage when appropriate
Understanding your utility’s specific compensation structure
Planning for long-term utility rate increases
Solar is no longer simply about producing as much excess power as possible—it’s about designing the right solution for your home.
Final Thoughts
Net metering changes have reshaped how solar savings work for many California homeowners, but they have not eliminated the opportunity to reduce long-term energy costs.
The key difference is that homeowners now need to pay closer attention to:
Their utility provider
Their rate structure
Their energy usage habits
System design and sizing
Available battery/storage options
As California’s energy market continues evolving, understanding these factors can help homeowners make more informed decisions about their long-term savings strategy.
