Load Analysis
A calculation of the total electrical demand of a home or building, accounting for all circuits, appliances, and future additions like EV chargers or heat pumps. Required for panel upgrade decisions.
Why It Matters
Before adding solar, batteries, or EV chargers, an electrician performs a load analysis to determine if your electrical panel can handle the additional demand.
