If you're a solar customer with one of the big three utilities in California, adapting to the new Net Energy Metering 3.0 (NEM 3.0) policy can seem challenging, but there are several strategic steps you can take to maximize your savings. Here's how to make the most out of your solar investment:
1. Optimize for Self-Consumption
Why It Matters: Under NEM 3.0, the compensation for excess energy returned to the grid is significantly lower than under previous NEM policies. Therefore, using the energy you produce rather than exporting it is key to savings.
Action: Monitor your energy usage and try to align it with your solar production. For instance, run high-energy appliances like washing machines or dishwashers during peak solar production times. If you have battery storage, configure it to store excess daytime production for use during non-solar hours.
2. Leverage Time-of-Use (TOU) Rates
Why It Matters: NEM 3.0 introduces a TOU rate structure where electricity rates vary by time of day.
Strategy: Use energy when rates are lower (off-peak hours) and store or consume your solar power when rates are high (peak hours).
Action: Understand your utility's TOU schedule and adjust your energy consumption habits accordingly. If you have a battery system, program it to charge during low-cost times and discharge during high-cost periods.
3. System Design for Maximum Efficiency
Why It Matters: The orientation of your panels affects when your system produces the most energy.
South-Facing: Best for midday production.
West-Facing: More beneficial if your usage peaks in the late afternoon or evening.
Action: If possible, opt for a system design that matches your electricity usage pattern. If you use more power in the evening, consider west-facing panels or a combination of orientations.
4. Battery Integration
Why It Matters: Even if you didn't initially plan for a battery, under NEM 3.0, they can significantly enhance savings by allowing you to store energy for use when it's most cost-effective.
Action: If you haven't already, consider adding battery storage. Discuss your options with your installer to see how it can benefit your specific setup. Batteries can store excess solar energy for use during peak rate times or when solar production is low.
5. Stay Updated with Utility Policy Changes
Why It Matters: Utility rates and policies can change, affecting your solar system's economics.
Action: Regularly check for updates from your utility provider or subscribe to newsletters from solar companies to stay informed. Being proactive can help you adjust your strategy in response to new opportunities or challenges.
6. Utilize Smart Home Technologies
Why It Matters: Automation can help manage your energy more efficiently.
Action: Invest in smart devices for your home appliances and lighting to optimize usage around solar production and TOU rates. Smart thermostats, lighting controls, and appliance timers can shift energy use to more favorable times.
By understanding and implementing these strategies, you can significantly enhance your savings under NEM 3.0. The key is to consume as much of the energy you produce as possible, smartly use your storage capabilities, and stay adaptable to changes in utility policies. If you need more personalized advice, consulting with your solar installation company can provide tailored recommendations for your system.
