Battery & backup · Manassas, VA
Solar battery installation in Manassas, VA
Why this changed in 2026 · as of August 2026
In Manassas, City of Manassas Utilities credits exported solar at set by the city under its own net metering policy while retail power costs set by the city, 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 Manassas is now an economic decision as much as an outage-protection one.
Local storage case
Why storage does or does not fit in Manassas
Whether a battery earns its place in Manassas depends on the city’s netting terms, and we do not have those from a citable source. If the city credits exports close to retail, as Dominion does under the preserved arrangement, then storage here is a resilience decision rather than an economic one. If it credits below retail, the arithmetic shifts toward a battery in the way it does in Georgia.
We will not model storage against an assumed export treatment. What we can say without the number is that Northern Virginia sees enough summer storm and winter ice activity that outage cover is a legitimate reason to want one, sized for essentials over a couple of days rather than for whole-house backup.
Written for Manassas 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, City of Manassas Utilities 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 Manassas was mostly about riding out storm-season outages.
That ended on December 31, 2025. Under municipal net metering policy, adopted 2015, exports credit at set by the city under its own net metering policy on a time-of-use basis, settled against your usage over the year. You still buy power at set by the city, 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 municipal net metering policy, adopted 2015 rate structure rewards. Backing up essentials well beats undersizing a whole-house dream, and it costs less.
- 02
Permits, City of Manassas Utilities interconnection and HOA
City of Manassas (independent city) 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 Manassas
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 Manassas 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.
Manassas specifics
What storage involves here
Manassas has its own constraints. Getting these right is most of the job.
- 01
A separate electrical permit
City of Manassas (independent city) 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, with summer cooling peaks aligned to peak production and reduced winter output. Whether that averages out across the year depends on the city’s netting terms rather than on state law.
- 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.
Manassas battery FAQ
Battery questions from Manassas homeowners
Is a home battery worth it in Manassas in 2026?
The economics improved when net metering changed. City of Manassas Utilities credits exported power at set by the city under its own net metering policy while you buy power at set by the city, 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 Manassas 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 Manassas?
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 City of Manassas (independent city)?
Yes. Battery storage requires an additional electrical permit alongside the permits for the solar system itself in City of Manassas (independent city), 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.
