Utility guide
Solar on Dominion Energy SC
If Dominion Energy South Carolina is on your bill, export credits, interconnection timing, and coastal/HOA design constraints shape the project as much as panel choice.
Export credits after 1:1 net metering
For many new residential systems, Dominion’s Solar Choice framework credits exported energy differently than older 1:1 net metering. Self-consumption (using power when you generate it) and optional storage become more important in the design conversation. We will not quote you using expired net-metering assumptions.
Interconnection & paperwork
We handle utility interconnection paperwork as part of the project, alongside permits and (when needed) HOA architectural review—common across Mount Pleasant, Daniel Island, and many Charleston neighborhoods.
Local design factors
- Coastal wind load and roof condition
- Historic / BAR constraints on the peninsula and older districts
- HOA placement and visibility rules
- Storm-season backup goals (battery vs generator)

Dominion solar FAQ
Questions from Dominion customers
Does Dominion still offer 1:1 net metering for new homes?
Under Dominion’s current framework for new residential systems, classic 1:1 net metering ended for systems interconnecting after December 31, 2025. New systems typically fall under Solar Choice export / time-of-use style crediting. Confirm the tariff that applies when you apply.
What cities does this guide cover?
Dominion serves large parts of the Charleston metro (Charleston, Mount Pleasant, North Charleston, Summerville, Daniel Island, and more), plus other SC markets. Some addresses nearby are co-op or Santee Cooper—we verify from your meter.
Do I need a battery on Dominion?
Not always. Batteries help with outages and can improve self-consumption when export credits are below retail. Whether it is worth it is a home-specific math problem we run during the assessment.
