Solar Add-Ons
Already Have Solar? Let's Make Sure You Have Enough.
Your electricity needs may have changed since your solar system was installed. SunSoCal specializes in helping Southern California homeowners expand existing solar systems with additional panels and Tesla Powerwall battery storage.
Having solar doesn't necessarily mean your electricity bill disappears.
Maybe your original solar company installed a system that was too small. Maybe you purchased an electric vehicle, installed a swimming pool, or started using more electricity. Whatever the reason, your original solar installation doesn't have to be your final one.
At SunSoCal, we help homeowners evaluate their current solar production, understand their electricity consumption, and explore options for generating and storing more of their own energy.
Why homeowners need more solar
Your Life Changes. Your Energy Needs Change With It.
You Purchased an Electric Vehicle
You Installed a Swimming Pool or Spa
Your Family Is Growing
Your Air Conditioning Usage Increased
You Added an ADU or Home Addition
Your Original System Was Too Small
Still getting an electricity bill?
You Already Invested in Solar. Why Are You Still Paying Your Utility Company?
Your bill may remain high because:
- Your system produces less electricity than your household consumes.
- Your electricity usage has increased.
- You consume significant electricity after sunset.
- Your utility uses time-of-use electricity rates.
- Your system is not producing as expected.
- Your utility billing arrangement affects how solar energy is credited.
SunSoCal can review your electricity usage and existing solar production to help determine what may be happening.
More Panels Aren't Always the Only Answer.
Sometimes additional solar production makes sense. Other times, battery storage may be worth considering. And in certain situations, the first step is simply understanding whether your current system is operating correctly. Our goal is to help you evaluate the right solution for your home.
Expansion feasibility
Yes, Many Existing Solar Systems Can Be Expanded.
Existing Equipment
Your current inverter, panels, monitoring equipment, and electrical configuration may affect your expansion options.
Available Roof Space
We evaluate whether your roof has appropriate space for additional panels.
Electrical Capacity
Your home's electrical infrastructure must be evaluated to determine what additional equipment it can support.
Utility Requirements
Your utility provider may have specific requirements for system expansions.
Existing Solar Agreement
If your current system is leased, financed, or under a power purchase agreement, the terms of that agreement may affect available options.
Current Net Metering Arrangement
Homeowners with older solar systems may have legacy utility billing arrangements that should be carefully reviewed before expanding.
Legacy net metering
Have NEM 2.0? Understand Your Options Before Adding Panels.
Many Southern California homeowners installed solar under older net energy metering programs. These arrangements can differ significantly from the billing rules that apply to newly interconnected solar systems.
When considering additional panels, it's important to understand how the proposed expansion could affect your existing utility agreement. Depending on your utility, system size, equipment configuration, and applicable rules, different expansion approaches may be available.
Some homeowners may qualify for limited changes without losing their legacy arrangement. Larger changes can trigger different requirements. A separate solar installation may be an option in some circumstances, but it does not automatically preserve an existing NEM agreement.
