ELECTRICAL PANEL

When to Upgrade Your Electrical Panel

Your electrical panel is the brain of your home's electrical system. If it can't handle the added load of solar, battery, and modern appliances, you'll need an upgrade before installation.

Signs You Need an Upgrade

Your panel is rated at 100 amps or less (most solar + battery systems need 200 amps)

You're adding solar + battery storage + EV charger

Your breaker box is full with no available breaker slots

You have an older Federal Pacific, Zinsco, or fuse-type panel (safety hazard)

You're experiencing frequent breaker trips

You're planning to electrify your home (heat pump, induction cooktop, etc.)
