Mac & Mac Electric upgrades and replaces electrical service panels for homes and businesses throughout Bellingham, Whatcom County, Skagit County, and San Juan County. Whether your existing panel is undersized, aging, or not solar-ready, we handle the complete replacement from permits through final inspection.

We most commonly upgrade homes from 100A to 200A service, and from 200A to 320A or 400A solar-ready configurations. A properly sized, modern service panel is essential for safely adding EV chargers, heat pumps, battery backup systems, or solar.

  • Meter base replacement

  • Solar-ready panel configurations
