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.
