What drives solar panel installation cost
- System size (kW): Bigger systems cost more up front but offset more of your electric bill — sizing to your usage matters.
- Equipment quality: Premium panels and inverters (and microinverters) cost more but produce more and last longer.
- Roof type & complexity: Steep, multi-plane, tile, or shaded roofs raise the install labor.
- Battery storage: Adding a home battery for backup or time-of-use savings adds several thousand dollars.
- Incentives: The federal tax credit and any state or utility rebates reduce the net cost well below the sticker price.
San Diego cost factors
San Diego's mild coastal climate is easy on equipment, but salt air can accelerate corrosion on rooftop HVAC and metal roofing. The high cost of living and California permitting keep project prices above the national average.
