1. Why 100A Electrical Panels Bottleneck Modern Clean Energy
Older Southern California homes built before 1995 often feature 100-amp or 125-amp service panels. When adding solar panels, home battery storage, and a 50-amp Level 2 EV charger, electrical demand exceeds the 120% NEC code safety threshold.
2. Step-by-Step Panel Upgrade Process
- Step 1: Utility Spot Inspection: SCE or SDG&E inspects service drop clearance and transformer capacity.
- Step 2: City Permitting: AD Solar submits engineered load calculations to the local building department.
- Step 3: Installation & Power Cut: Same-day physical replacement with commercial-grade copper busbar panel.
- Step 4: City Inspection & Meter Release: City inspector signs off and the utility reconnects permanent power.
