Main Electrical Panel Upgrades in Castle Rock, Colorado
Getting Castle Rock homes ready for solar, batteries, EV chargers, and heat pumps — panel upgrades by our own licensed electricians.
Panel Upgrade for Castle Rock homes
Many Castle Rock homes still run on 100–150 amp panels sized for a gas-powered era. Add an EV charger, a heat pump, or solar with battery backup, and that panel runs out of space and capacity fast. We upgrade panels to modern 200-amp service — permits, inspection, and utility coordination included.
A panel swap means a brief planned outage, so we schedule the disconnect and reconnect with CORE Electric Cooperative in advance to keep your downtime as short as possible.
