Solar battery installation in Woodbridge, VA
Why this changed in 2026 · as of August 2026
In Woodbridge, Dominion Energy Virginia credits exported solar at credited one-for-one at retail against your own annual usage while retail power costs the applicable residential retail rate, confirmed against your own bill. That means a kilowatt-hour you store and use yourself is worth roughly three to five times one you export. Storage in Woodbridge is now an economic decision as much as an outage-protection one.
Local storage case
Why storage does or does not fit in Woodbridge
Storage in Virginia is a resilience decision rather than an economic one, and we would rather say that plainly than sell a battery on arithmetic that does not hold here. Where exported power is credited at retail, holding production back to use later does not capture a spread, because there is no spread to capture. That is the opposite of the case we make in Georgia, and it is a direct consequence of the 2026 ruling.
What a battery does buy you is outage cover, and Northern Virginia sees enough summer storm and winter ice activity for that to be a real consideration. We size for essentials over a couple of days, refrigeration, lighting, internet, a well pump where there is one, rather than for running central air through a multi-day event, which is a much larger and more expensive system than most people picture.
Written for Woodbridge specifically. Your own roof, bill and meter still decide the answer, which is what the free assessment settles.
The maths changed
Storing a kilowatt-hour now beats exporting one
Until the end of 2025, Dominion Energy Virginia credited exported solar close to one-for-one. Sending surplus power to the grid was almost as good as using it, so a battery in Woodbridge was mostly about riding out storm-season outages.
That ended on December 31, 2025. Under net energy metering under §56-594, exports credit at credited one-for-one at retail against your own annual usage on a time-of-use basis, with a rider of about $1 a month for customers connecting under NEM 2.0 and a November true-up at avoided cost. You still buy power at the applicable residential retail rate, confirmed against your own bill. The gap between those two numbers is the entire case for storage.
A battery closes that gap. Instead of exporting afternoon surplus for a few cents and buying evening power back at full retail, you store the surplus and spend it yourself. For a household that is out during the day and home in the evening, this is the difference between a system that barely moves the bill and one that does what you expected.
We are not going to promise you a figure for that, because it depends on your usage shape and your rate. What we will do at the assessment is model your actual load profile against your actual rate and show you whether storage earns its cost at your address.

We handle everything
From critical-load mapping to switched-on
- 01
Critical-load mapping, not box-selling
We start from what you actually need running in an outage and what your net energy metering under §56-594 rate structure rewards. Backing up essentials well beats undersizing a whole-house dream, and it costs less.
- 02
Permits, Dominion Energy Virginia interconnection and HOA
Prince William County requires a separate electrical permit for storage on top of the solar permits. We pull all of it, file the interconnection, and prepare the architectural-review packet where a board or HOA is involved.
- 03
Installation and critical-loads panel
Our crews install the battery and tie it to a critical-loads subpanel with automatic switchover, so backup engages the moment the grid drops. No manual steps, no extension cords.
- 04
Commissioning and monitoring
We commission the system, walk you through the app so you can see state of charge and what is protected, and stay reachable long after activation.
Every battery install carries our lifetime full-system and roof-penetration warranty, on top of the manufacturer's battery warranty.
Honest numbers
What drives battery cost in Woodbridge
There is no honest fixed price for a battery. These are the real drivers, and a free assessment turns them into a figure for your home.
Usable capacity
How many kilowatt-hours you want available, and whether you stack more than one unit. This is the largest single factor.
Electrical work
Adding a critical-loads subpanel, and any service-panel upgrade your home needs first. Common on older Woodbridge properties.
Retrofit or new build
Pairing storage with a new system is cleaner than retrofitting to an existing inverter that was never specified for it.
Woodbridge specifics
What storage involves here
Woodbridge has its own constraints. Getting these right is most of the job.
- 01
A separate electrical permit
Prince William 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
Four genuine seasons. Summer cooling peaks align with peak production, winter output drops with the sun angle, and snow cover costs a few days a year. Retail net metering smooths that across the year in a way an export-credit state cannot.
- 03
Where the battery goes
Placement matters mostly for heat. Batteries dislike an unconditioned attic or a west-facing wall in a Midlands summer, so garage-interior siting is usually right.
- 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.
Woodbridge battery FAQ
Battery questions from Woodbridge homeowners
Is a home battery worth it in Woodbridge in 2026?
The economics improved when net metering changed. Dominion Energy Virginia credits exported power at credited one-for-one at retail against your own annual usage while you buy power at the applicable residential retail rate, confirmed against your own bill, so a kilowatt-hour you store and use yourself is worth roughly three to five times one you export. That is a stronger case than under the old one-for-one net metering, on top of the outage protection.
How long will a battery run my house during a Woodbridge outage?
It depends on usable capacity and what you back up. Most homeowners back up essentials, refrigerator, lights, Wi-Fi, well pump, medical equipment, a few outlets, which stretches runtime far longer than trying to run central air. During your assessment we map your critical loads so you know realistically what to expect rather than a marketing number.
Can I add a battery to solar I already have in Woodbridge?
Usually yes. Many existing systems can be retrofitted with a battery and a critical-loads panel. We check your current inverter, panel capacity and interconnection status first, and tell you honestly whether it is a clean add-on or needs additional equipment.
Do I need solar to get a battery?
No. A battery can be installed on its own to back up your home from the grid, though pairing it with solar lets you recharge from your own panels instead of only from the utility. We will walk through both options based on your goals.
Does battery storage need a separate permit in Prince William County?
Yes. Battery storage requires an additional electrical permit alongside the permits for the solar system itself in Prince William County, and the installation must satisfy the National Electrical Code as adopted in Virginia. We pull the permits and handle the inspection sequence as part of the project.
Is there a Virginia tax credit for battery storage?
Virginia has no state income tax credit for residential solar, and the federal residential credit expired for systems placed in service on or after 1 January 2026. The expired federal credit no longer applies. Confirm your own position with a tax professional.
