Table
Panel Upgrade Cost Ranges for EV and Solar Projects
Panel Upgrade Cost Ranges for EV and Solar Projects reference with assumptions and boundary notes.
Reference boundary
Cost planning reference only. It does not determine whether a panel upgrade is required or approved for EV, solar, or storage work.
Reference table
Compare representative panel-upgrade cost drivers for EV charging and solar projects.
| Project trigger | Cost driver | Low (CAD) | High (CAD) | Boundary |
|---|---|---|---|---|
| EV charger load addition | load calculation and available panel/service capacity | 2500 | 6500 | cost driver reference only; does not decide whether an upgrade is required |
| Solar backfeed or interconnection | panel bus rating, breaker space, and utility interconnection path | 2000 | 6000 | cost driver reference only; does not decide whether an upgrade is required |
| Battery backup subpanel | critical-load panel, transfer equipment, and wiring scope | 3000 | 9000 | cost driver reference only; does not decide whether an upgrade is required |
| Service size increase | utility coordination, mast/meter/service equipment, and permit scope | 5000 | 15000 | cost driver reference only; does not decide whether an upgrade is required |
| Panel replacement only | age, spaces, breaker compatibility, and working-clearance corrections | 2000 | 5000 | cost driver reference only; does not decide whether an upgrade is required |
Use notes
- Use this table for preliminary reference and arithmetic checks only.
- Confirm equipment ratings, product markings, installation conditions, utility requirements, and the local authority requirements before design or field use.
