Local storage case
Why storage does or does not fit in McDonough
Storage does more work in McDonough than anywhere else we operate. Where the export credit is a small fraction of the retail rate, every kilowatt-hour a battery keeps at home instead of exporting captures most of that gap rather than a slice of it. In practice a battery is rarely an upgrade to the case for solar here. It is frequently what makes the case exist at all.
Written for McDonough specifically.
The maths changed
Storing a kilowatt-hour now beats exporting one
Snapping Shoals EMC sets its own export credit through its own board, so we confirm the current figure per account before modelling anything.
You still buy power at a rate set by the cooperative board, confirmed against your own bill. Each kWh stored instead of exported is worth that rate rather than a rate set by the cooperative rider, confirmed per account.
In McDonough, a 9.5 kW system makes up to about 1,299 kWh in May; most of the afternoon surplus is what a battery would hold.
We model your Snapping Shoals EMC usage at the assessment and show whether storage earns its cost.
How it works
How battery installation runs in McDonough
Critical-load mapping, an extra electrical permit through Henry County, installation with a critical-loads subpanel, then Snapping Shoals EMC approval and commissioning.
Cost
What drives battery cost in McDonough
Hot Georgia summers with long afternoon cooling load and occasional storm outages. Capacity and the number of Henry County circuits you back up set the price.
McDonough specifics
What storage involves here
McDonough has its own constraints. Getting these right is most of the job.
- 01
A separate electrical permit
Henry County requires one for storage on top of the solar permits, with its own inspection. We pull it and meet it.
- 02
Your outage profile
Hot Georgia summers with long afternoon cooling load and occasional storm outages.
- 03
Where the battery goes
Placement matters mostly for heat. Garage-interior siting usually beats an unconditioned attic here.
- 04
Service panel capacity
Older services often need attention before storage can be added cleanly. We run the load calculation before quoting, not after.
- 05
Battery or generator?
For very long outages a standby generator can be the better answer, and we will say so if it is. Compare the two.
- 06
Retrofit or new build
Pairing storage with a new system is cleaner than retrofitting to an inverter that was never specified for it. We check yours first.
Permits and approvals
What approval takes in McDonough
4 approvals for a McDonough system. We file every one.
- 01A building permit and a separate electrical permit from the City of McDonough or Henry County, depending on the address
- 02An interconnection agreement with whichever provider serves your meter
- 03An additional electrical permit where battery storage is included
- 04A zoning review as well for any ground-mounted array

McDonough battery FAQ
Battery questions from McDonough homeowners
Is a home battery worth it in McDonough in 2026?
Snapping Shoals EMC sets its own export credit through its own board, so we confirm the current figure per account before modelling anything.

Does battery storage need a separate permit in Henry County?
Yes. Battery storage requires an additional electrical permit alongside the permits for the solar system itself in Henry County, and the installation must satisfy the National Electrical Code as adopted in Georgia. We pull the permits and handle the inspection sequence as part of the project.
