Older panels and detached garages
Many older Denver homes still have 100-amp service, and a 48-amp charger on top of an electric range and dryer can exceed what the panel can safely carry. A load calculation tells us whether you need a panel upgrade, a smaller charger setting, or a load-management device.
Detached garages off an alley mean a longer trench or conduit run. That’s the most common reason a Denver install lands at the top of our price range.
Charge off-peak, or charge from the roof
On Xcel’s time-of-use rate, charging after 9 pm or on weekends avoids the weekday 5–9 pm peak. If you have solar, a midday charge on a work-from-home day uses your own production directly.
For Denver homeowners who want backup without a separate home battery, a bidirectional EV system — from about $19,000 with us — lets a compatible vehicle power the house during an outage.
Permits and rebates
EV chargers go through Denver’s standard electrical permit, not SolarAPP+. Xcel has offered home-wiring rebates for EV chargers tied to enrollment in its managed-charging program, with higher amounts for income-qualified customers. The federal §30C credit ended for chargers placed in service after June 30, 2026. Verify current terms before you buy.
FAQ
Questions we hear
Do I need a permit to install an EV charger in Denver?
Yes — a standard electrical permit from Community Planning and Development. Chargers aren’t eligible for Denver’s SolarAPP+ quick permits.
My Denver bungalow has a 100-amp panel. Can I still get a Level 2 charger?
Often, yes. A load calculation may show room for a lower-amperage charger, or you may need a load-management device or panel upgrade. We check before quoting.
When should I charge my EV on Xcel’s time-of-use rate?
Outside 5–9 pm on non-holiday weekdays. Overnight and weekend charging is the cheapest grid power on the schedule.
Does Xcel offer a rebate for EV charger wiring?
Xcel has offered wiring rebates for customers who enroll in its charging program. Check the current amount and eligibility before your install.
