Non-Export Solar Systems for Southern California Edison (SCE) and San Diego Gas & Electric (SDG&E) Customers
Solar energy is a great way to save on electricity bills, especially in sunny Southern California. If you’re a customer of Southern California Edison (SCE) or San Diego Gas & Electric (SDG&E), you’ve likely heard of non-export solar systems. These systems allow you to use the solar energy you generate onsite without sending excess energy back to the grid. With recent changes in utility programs, non-export solar systems can be a smart choice for many homeowners and businesses.
What is a Non-Export Solar System?
A non-export solar system is designed to keep all the energy you generate for use at your home or business. If you produce more energy than you need, the surplus is stored in batteries instead of being sent back to the grid. This differs from traditional solar systems that feed extra power back to SCE or SDG&E in exchange for credits through net energy metering (NEM) programs.
Why Consider a Non-Export Solar System with SCE or SDG&E?
- Changes to Net Energy Metering (NEM 3.0)
SCE and SDG&E have updated their net metering policies, meaning customers now receive less money for the energy they send back to the grid. Non-export systems let you avoid relying on lower returns and instead use or store all the energy you produce, maximizing your savings. - Avoid Peak Pricing with Time-of-Use (TOU) Rates
Both SCE and SDG&E use Time-of-Use (TOU) rates, where electricity is more expensive during peak hours. Non-export systems, paired with battery storage, allow you to store energy during the day and use it during expensive peak periods, saving money on your electric bill. - Energy Independence During Power Outages
Southern California faces periodic Public Safety Power Shutoffs (PSPS), especially during wildfire season. With a non-export system and battery storage, you can keep your home powered even during grid outages. This is especially valuable in areas prone to blackouts. - Simplified Grid Connections
In rural or remote areas, connecting a traditional solar system to the grid can be costly or complex. Non-export systems let you generate and use solar energy onsite without needing extensive grid upgrades.
Considerations for Non-Export Systems
While non-export solar systems have many advantages, there are a few things to keep in mind:
- Higher Upfront Costs
Non-export systems, especially those with battery storage, can be more expensive to install initially. However, over time, the savings from reduced utility bills can offset these costs. - System Sizing
It’s important to size your system correctly. A system that’s too large may waste energy, while one that’s too small might not meet your needs. Proper planning and energy management are key. - Battery Maintenance
Batteries require maintenance and will eventually need to be replaced. Consider the long-term upkeep when planning your system.
Maximize Your Benefits
If you’re an SCE or SDG&E customer, there are ways to get the most out of a non-export solar system:
- Use TOU Rates to Your Advantage: Store energy during cheaper, off-peak times and use it during expensive peak hours.
- Take Advantage of Incentives: Federal tax credits and California’s Self-Generation Incentive Program (SGIP) offer rebates for battery storage, helping lower installation costs.
- Prepare for Power Outages: A non-export system with batteries ensures you have backup power during blackouts, giving you energy independence.
For SCE and SDG&E customers, non-export solar systems offer energy savings, independence, and protection from rising electricity rates. With changes to net metering and the need for reliable power during outages, these systems are an excellent option. While they may have higher upfront costs, the long-term benefits make them a wise investment for Southern California homeowners and businesses.
By working with a solar installer and taking advantage of available incentives, you can customize a system that meets your energy needs and provides long-term savings.
