If you’ve noticed more solar panels popping up on rooftops around Sacramento, Roseville, or Elk Grove, you might be curious about the latest rules impacting home solar in California. Recent changes introduced by the California Public Utilities Commission (CPUC) now affect how homeowners are credited for solar energy sent back to the grid. Understanding how these "net export" systems work under California’s NEM3 (Net Energy Metering 3.0) is crucial for making the most of your solar investment.
What is NEM3 and Why Does It Matter?
The jump from NEM2 to NEM3 has changed the game for solar users across California, including those in SMUD and PG&E territories like Folsom or Citrus Heights. NEM3 replaces the earlier net metering rules, which previously credited solar users at nearly retail electricity rates for any surplus power they generated. Now, with NEM3 in effect (as of April 2023 for most utilities), exported energy is credited at a value much closer to the utility’s actual cost of buying power, not the price you pay as a customer. This new approach is referred to as "net billing."
Key Differences Between NEM2 and NEM3
– **Export Rates:** Under NEM3, credit for exported energy is lower and varies by the hour. NEM2 offered higher and more predictable credits.
– **Time-of-Use (TOU):** NEM3 emphasizes TOU rates, rewarding exports during high-demand periods.
– **Battery Storage Incentives:** Battery storage systems are now more valuable, as they let you export power when rates are highest.
How Net Export Systems Operate Under NEM3
When your solar panels produce more electricity than your home consumes—say, during a sunny Sacramento afternoon—that excess energy flows out to the grid. Under NEM3’s net export rules, you receive a credit based on the real-time value of the energy you export, not a fixed retail rate. The specific export rate fluctuates through the day, reflecting the wholesale price of electricity and the grid’s needs.
Net Export Rate Timing: What’s New?
Utilities such as SMUD and PG&E have established hourly rates that change throughout the day:
– **Daytime (low demand):** Lower export credits, since there’s already lots of solar power on the grid.
– **Evening (peak demand):** Higher export credits, as demand spikes and less solar is available.
For Sacramento electricity rates, this means most exported solar credits are worth much less than the price you pay for electricity, except during a few short evening windows.
Maximizing Home Energy Savings Under NEM3
Optimizing your solar savings in California has become more strategic. With NEM3, you need to be smarter about when and how you use—and export—your home’s solar power.
The Role of Home Battery Storage
Installing solar battery storage allows you to store that midday surplus and release it or export it to the grid during peak-value hours. By combining solar panels with a battery, homeowners in areas like Elk Grove or Folsom can keep more of their solar energy, using it when electricity rates are highest or exporting it when credits are most lucrative.
Smart Usage Patterns and Energy Management
– **Shift Usage:** Run energy-intensive appliances (laundry, EV charging) during mid-day when your solar is producing.
– **Export Timing:** Use batteries or smart energy management to export power during peak periods (for instance, 5–9 PM for PGE customers).
– **Monitor Utilities:** Stay up-to-date with your local utility’s (SMUD, PG&E) TOU periods and current rates, as these directly impact your export compensation.
Comparing Net Billing With Previous Policies
Under NEM2, homeowners could expect faster payback periods from their solar installations thanks to higher export credits. The update to NEM3 may extend those payback times, but solar is still a strong investment—especially if paired with battery storage and mindful energy management.
Example: Sacramento Area Rate Comparison
– **NEM2**: 1 kWh exported = Credit close to $0.20–$0.30/kWh (depending on utility)
– **NEM3**: 1 kWh exported = Credit around $0.05–$0.10/kWh mid-day; up to $0.30+/kWh in evening peaks
Homeowners using net export systems must now adjust how they use solar—not just how much they produce.
Next Steps: Getting the Most from Your Solar Panels Under NEM3
With California’s NEM3 now in effect, getting the best return on your solar panel investment requires careful planning and the right technology. Whether you’re looking to install new solar panels, add battery storage, or optimize your energy usage to suit Sacramento electricity rates and utility net billing policies, working with a knowledgeable, local solar installer is the best way forward.
