Solar quotes for denser, shadier rooftops
Arlington and Alexandria are not standard suburban solar markets. Smaller roof planes, mature tree canopy and historic districts all change the design. We match you with installers who work these properties regularly — and you compare their bids side by side.
Why It's Different Here
Dense housing changes the solar math
A quote that works in Loudoun County may not be the right system for an Alexandria rowhouse. Here is what actually drives pricing in Arlington and Alexandria.
Roof area is the constraint
Rowhouses and older homes often have less usable roof plane than a suburban build. Systems tend to be smaller, which can mean fewer panels but a higher price per watt once fixed costs are spread across a smaller array.
Shade analysis is not optional
Mature tree canopy covers much of Arlington and Old Town Alexandria. A real production model accounts for the shade; an estimate that ignores it will overstate what your system actually generates.
Historic review may apply
Parts of Alexandria fall within historic districts with design review. Not every property is affected, but it is worth asking before installation rather than discovering it mid-project.
Two bids, two different designs
Because these rooftops are non-standard, installers genuinely propose different layouts, panel choices and array sizes. That is exactly why comparing matters more here — you are comparing engineering approaches, not just prices.
Utility territory is consistent
Arlington and Alexandria sit within Dominion Energy Virginia territory, so net metering rules apply uniformly across both jurisdictions. That part of the equation is simpler than the roof itself.
Older housing stock, older roofs
Many homes here predate modern roofing standards. If your roof needs replacement within a decade, sequencing that correctly usually matters more to your economics than the panel brand.

Common Questions
Solar in Arlington & Alexandria, answered
Can you install solar on an Arlington or Alexandria rowhouse?
Often yes, but the design is different from a suburban install. Rowhouses typically have narrower roof planes and shared party walls, so installers work with smaller arrays, more careful layout, and sometimes higher-efficiency panels to fit the available square footage. An installer who regularly works Arlington and Alexandria housing stock will recognize these constraints immediately.
How much does solar cost in Arlington or Alexandria?
Because rowhouses and older homes often fit smaller systems, gross prices in Arlington and Alexandria frequently run lower than larger Fairfax County installs — commonly in the high teens to high twenties depending on system size and equipment tier. Per-watt pricing, though, can be higher because fixed costs are spread across fewer panels.
Does tree canopy in Arlington make solar impractical?
It is the single biggest factor to evaluate here. Arlington and Alexandria have mature tree canopy that can shade roofs, especially in older neighborhoods. It does not automatically rule out solar, but it does mean a real shade analysis matters more than in newer suburbs — and it may change which roof plane is the right one.
Do historic districts in Alexandria restrict solar panels?
Alexandria has historic districts with design review requirements, and some properties may face additional review before installation. Requirements vary by district and by how visible the panels would be from the street. Ask any installer you are considering whether they have worked within the relevant district before.
Is net metering available in Arlington and Alexandria?
These areas are served by Dominion Energy Virginia, which must offer residential net metering. That means excess production is credited against your grid draw. Program terms have been adjusted in recent years, so confirm the current structure with your utility before signing.
How long does permitting take in Arlington or Alexandria?
Both jurisdictions review residential solar regularly, but historic district properties and older homes can take longer because of additional review steps. Physical installation is typically one to three days; the permitting and interconnection timeline is usually the longer part.
What should I ask an Arlington solar installer?
Ask how many systems they have installed in Arlington or Alexandria specifically, how they handle shade from mature canopy, whether they have worked within any applicable historic district, and what their workmanship warranty covers. Local experience matters more here than in most markets.
