Arlington is a county in Northern Virginia, across the Potomac River from Washington, DC, covering about 26 square miles. The county estimates 244,300 residents in 2026, in 120,240 households and 127,087 housing units. About 36% of homes are owner-occupied, and the median household income is $142,114 (2020–2024 survey). Detached single-family houses make up about 22% of the housing, and attached homes another 6%.
Residential and commercial solar panel installers do the same core job, design, permit and install a solar panel system, but the projects differ. Residential solar panels for your home in Arlington usually mean a detached house or a townhouse with a pitched roof and a smaller system. Commercial solar covers offices, shops and multifamily buildings with large, low-slope roofs, and these projects go through commercial plan review. Tell your solar panel installers which one you need first.

Solar panel installers in Arlington work within a few set numbers and rules:
| Topic | What to expect in Arlington |
|---|---|
| Price per watt | About $2.70 to $2.80, installed |
| Typical home system | About 9.8 to 10.7 kW |
| Utility | Dominion Energy Virginia |
| Local approval | Building permit (about 5 business days) and electrical permit (about 2 business days) from Arlington County Inspection Services |
| Switch-on | County final inspection, then Dominion exchanges the meter and commissions the system |
| Net metering | Home systems up to 25 kW; credits carry over for 12 months |
| Property tax | Qualifying home systems are exempt under Virginia law |
| Panel coverage | Most panels carry 25-year warranties |
Solar panel installation costs in Arlington run about $2.70 to $2.80 per watt, so a typical 9.8 to 10.7 kW home system comes to roughly $27,000 to $29,500 before incentives. The total moves with system size, equipment, racking, roof work and permits. For homes whose installation is completed after December 31, 2025, the federal tax credit no longer lowers it. Ask solar panel installers for a line-by-line quote so you see what drives your number.
Before you sign with solar panel installers in Arlington, make sure they pass four checks:
Solar warranty coverage comes in three layers, and solar panel installers should put each one in writing. Most panels carry 25-year warranties for the product and a performance warranty on their output. The inverter has its own inverter warranty. The workmanship warranty covers the installer’s labor, wiring and racking, and it ranges from 1 year up to 25 years. Ask who handles claims and maintenance before you sign.
Solar panel savings in Arlington come from the electricity your system makes and the credits it earns, and solar panel installers size the system so both add up:
Size the system to your yearly use rather than your full roof, since credits beyond it are worth less, and higher electricity rates make each credit worth more. Ask for a production estimate in kWh with your quote to see your own numbers.
Solar panel installers in Arlington work on pitched shingle homes and on the flat roofs of commercial buildings. Before any system design, a site survey checks:
On townhouses, panels must stay 4 feet from a firewall unless it has a parapet at least 30 inches high. Settle any repairs before installation day, so the array never has to come off.
Among solar panel companies in Arlington, Lumina Solar brings a long track record: 7+ years of experience, over 6,000 installations, more than 1,000 five-star reviews and NABCEP-certified installers. Of the solar installation companies serving Northern Virginia, Lumina Solar takes care of the hassles, paperwork and permits for you, from the first design through interconnection to permission to operate, and it is licensed in Virginia (2705180875). If you want solar panel providers who stay involved after installation day, Lumina Solar adds a monitoring app and ongoing support. Ask Lumina Solar to design a system for your home.
Solar system design is where good solar panel installers start, with a consultation. Lumina Solar uses satellite imaging of your property and a look at your energy use to plan a solar panel system that fits. The design sets the number of panels, the inverter type and the racking layout. Two inverter setups are common: microinverters on each panel, which handle partial shade well, and a string inverter that serves a group of panels. Monocrystalline panels with high panel efficiency fit the most power into a small space. Ask to see the design before the survey.
The site survey brings Lumina Solar’s surveying and engineering team to your property for an in-person check. They measure the roof, look at the attic framing and inspect your electrical system, including the main electrical panel the system will connect to. The survey confirms the system design, the equipment layout, the racking plan and the inverter location, and the team answers your remaining questions on the spot.
Solar permits in Arlington come from the county’s Inspection Services Division: rooftop systems on single-family homes and townhomes need both a building permit, with about 5 business days for initial review, and an electrical permit, with about 2. In parallel, the signed interconnection agreement goes to Dominion Energy, ideally before installation. Virginia law also limits how far a homeowners’ association can restrict panels on your own roof. Lumina Solar takes care of this paperwork for you, which sets most of the timeline.
Solar panel installation day is often the shortest step in the timeline: on most homes, Lumina Solar completes the work within a few hours, depending on system size. The crew of solar panel installers fixes the racking, mounts the panels, wires the inverter and adds the rapid shutdown equipment the code calls for, then leaves the site clean and ready for inspection. Plan for access to the roof and the electrical panel that day.
After the solar panel installers finish, the solar panel system goes through inspection: Arlington County staff carry out the final inspection under the permits. After its interconnection review, Dominion Energy then exchanges the meter, commissions the system and gives permission to operate. Lumina Solar schedules the inspection and follows it through to keep your timeline on track. Once permission to operate arrives, your system starts producing power and earning credits.
Solar incentive paperwork comes next. Lumina Solar reviews the incentives open to your system and guides you through any applications. In Virginia, the system’s solar renewable energy certificates can be registered and sold once it has permission to operate, and qualifying home systems are exempt from state and local property tax. The federal tax credit does not apply to homes whose installation is completed after December 31, 2025, so check the date on your paperwork.
Solar monitoring and maintenance keep the system producing. From the day you have permission to operate, Lumina Solar gives you an app to track your system’s production at any time, and the team stays available for questions and ongoing support. Solar panels need little upkeep: snow slides off tilted panels as it melts, and a regular look at the monitoring data and the racking spots a drop in output early. Plan for an eventual inverter replacement, since inverters tend to wear out before panels do. Lumina Solar does not offer panel cleaning as a service; if your panels ever need cleaning, that is a job for a separate provider.
Solar panel incentives for Arlington homes come from Virginia programs. Home systems up to 25 kW are exempt from state and local property tax, net metering credits your exported power, and SRECs pay you for production. At the federal level, the 30% federal tax credit ended for installations completed after December 31, 2025. Ask solar panel installers to confirm which incentives fit your system before you sign.
Paying for solar panels comes down to who owns the system. Lumina Solar offers three ways to pay, including financing, listed below, and ownership decides who keeps the SRECs, any rise in home value and the maintenance.
The three ways to pay for a solar panel system, from cash to financing:
Weigh the total cost over each option’s term, not only the monthly figure, and ask your solar panel contractors how each one handles credits and maintenance.
Battery storage lets a solar panel system keep power for later. Lumina Solar offers battery solutions alongside solar panel installation, and solar panel installers size the battery to the loads you want to keep running. A battery is worth weighing if you want:
A battery adds to the total cost, so ask for a quote with and without one and see how the numbers change.
Lumina Solar is the best solar panel installation company in Arlington, because it meets the standards a careful buyer looks for:
This is Lumina Solar's own view, based on those factors. We would love to show you how we measure up.
Commercial solar differs from residential solar mainly in size and paperwork. Virginia net metering covers non-residential systems up to 3 megawatts, against 25 kW for a home, so a business roof can carry a far larger system. Commercial buildings also go through commercial plan review with the county, and their low-slope roofs need ballasted or anchored racking. Talk to Lumina Solar about what your building needs.
Paying someone to install solar panels in Arlington costs about $2.70 to $2.80 per watt, or roughly $27,000 to $29,500 for a typical home system before incentives or financing. The price per watt covers the equipment (panels, inverter and racking), labor, permits and inspection, and the federal tax credit no longer lowers it for homes completed after December 31, 2025. Lumina Solar can give you a free quote for your home.
Installing solar panels typically takes a few hours on site for most homes, but the full timeline takes longer, because the county's building and electrical permits, the final inspection and Dominion's meter exchange and commissioning each add time before permission to operate. Lumina Solar schedules each step for you.
The solar panel warranty usually lasts 25 years, since most panels carry 25-year coverage on the product and its output. The inverter and the installer's work are covered separately, and the installer's terms on the work range from 1 year up to 25 years, so read all three. Lumina Solar can walk you through every warranty on your quote.
PV installers are certified by the North American Board of Certified Energy Practitioners, the industry's leading certification for photovoltaic installers. Certification is voluntary, but in Virginia the contractor needs a DPOR license, and Arlington County requires state electrical licensing for the electrical work. Lumina Solar's installers are NABCEP-certified.
The solar system you need for a 2,000 sq ft house depends on how much electricity the home uses, not on its floor area; in Arlington a typical home system runs about 9.8 to 10.7 kW. Solar panel installers size it to offset what you use, from your past electric bills, your roof space and its peak sun hours. Lumina Solar sizes every system to your own household.
The type of roof that is not good for solar panels is one in heavy shade most of the day, one near the end of its life, or one that faces mostly north, because each cuts output or forces the panels off for repairs. Attached homes also need room for the firewall setback. Lumina Solar checks your roof before any design.
Financing solar panels is a good idea when the monthly payment stays close to or below the savings on your electric bill, because you keep ownership and the credits once it is paid off. A lease costs nothing upfront, but the solar provider owns the system. Since the federal tax credit ended for homes completed after December 31, 2025, compare the full cost of each option. Lumina Solar offers financing options that start at $0 down.
Battery storage with solar panels is worth having if you want backup power during outages or more of your own solar energy at night, because a system without a battery shuts off when the grid goes down. It adds to the total cost, so weigh what you want to keep running. Lumina Solar can quote your system with and without a battery.
Solar panels need very little maintenance: they have no moving parts, snow slides off as it melts, and the monitoring app shows when output drops. Over the years, plan for an inverter replacement, since inverters wear out before panels. Lumina Solar does not offer panel cleaning as a service; if your panels ever need cleaning, hire a separate provider for it.
Yes, you can monitor your solar panels after installation with an app that shows the solar energy your system makes, day by day. A sudden drop in output is the first sign that a panel, the inverter or the wiring needs a look. Lumina Solar gives you a monitoring app and ongoing support from the day you have permission to operate.
