Solar Add-Ons for Existing Solar Systems

If your energy usage has increased, adding solar panels to your existing solar system can help reduce utility bills and improve energy efficiency. AD Solar designs and installs custom solar panel add-ons for homeowners across Southern California. Adding panels to an existing solar system is often more cost-effective than installing a completely new solar system.

Common reasons homeowners upgrade their solar systems include:

Electric Vehicle Charging
ADUs & Garage Conversions
Home Additions
Pool Equipment
Increased Electricity Usage
New Appliances
NEM 3.0 Optimization
Battery Storage Integration
Energy Independence

Battery Storage Installation

AD Solar installs advanced battery backup systems that help homeowners store excess solar energy and reduce dependence on utility companies. We install battery storage systems compatible with both new and existing solar systems, including Tesla Powerwall and other leading battery technologies.

Backup Power During Outages
Lower Electricity Costs
Increased Energy Independence
Better NEM 3.0 Savings
Peak Rate Energy Reduction
Improved Solar Efficiency
Support When You Need It

Solar Orphan Services

If your original solar company is no longer in business, AD Solar can help. We provide professional solar orphan services for homeowners needing support for existing solar systems. Our experienced team can inspect your system, identify performance issues, and recommend the best solution to restore or improve production.

What is a solar orphan system? A solar orphan system is a solar installation that no longer has support because the original solar company closed or stopped servicing customers.

  • Solar system troubleshooting
  • Solar repairs and diagnostics
  • Inverter replacement
