Homeowners in Leesburg, Ashburn, and Middleburg are switching to solar, and so are local businesses. NEDES delivers solar installation services Loudoun County, VA, and is trusted by residents and business owners for lower monthly power costs. From HOA neighborhoods to office parks and rural land out west, we design systems built for each property. Every install is backed by real local permitting knowledge.
Electric bills are rising fast in Loudoun County, which is why more homes and businesses are going solar. Dominion’s SCC-approved rate hike adds $11.24 a month in 2026. That’s on top of an $8.95 fuel charge, pushing the average bill to $165. Local data centers are pushing commercial costs up too. Our solar installation services Loudoun County, VA, help both homeowners and businesses cut those costs. SEIA reports residential solar grew 6% year-over-year in Q1 2026. Commercial installs hit 523 megawatts nationally in that same quarter. Net metering and Loudoun’s tax exemption make switching pay off faster.
Loudoun gets about 4.5 to 5 peak sun hours a day. That’s enough to run a well-sized system through most of the year, whether it’s a home roof or a business rooftop. Homes and buildings out past Purcellville often get more sun than shaded lots in Leesburg or Waterford. Your real number depends on the roof, not the zip code.
The 30% credit for homeowners who buy or finance their own system ended on December 31, 2025, with no phase-out. Businesses are different: a company that owns its commercial solar system can still claim a 30% federal credit through 2027 under Section 48E. For homeowners, the only way left to reach that credit is through a Lease or PPA, where the financing company claims it and passes savings back at a lower rate.
Net metering still works at the full retail rate for both homes and businesses. Dominion Energy credits your excess solar power at the same price you’d pay to buy it back. That held up even after the state’s 2026 net metering review. It’s one of the strongest incentives Virginia has left.
Solar equipment is exempt from Virginia sales tax for residential and commercial purchases. That exemption applies right at the point of purchase, before financing even comes into play. It’s separate from the property tax break Loudoun County offers locally. Most residential and commercial systems qualify for both.
Virginia SRECs currently sell for around $20 to $35 per certificate. You earn one SREC for every megawatt-hour your system produces, and you can sell them separately from your utility bill. Cash and loan customers, including businesses that own their systems outright, usually keep ownership of their SRECs. Most lease and PPA deals hand that value to the financing company instead.
Loudoun’s solar property tax exemption is one of the strongest incentives left. It exempts 100% of the added value of your solar equipment from property tax for systems 25 kW or smaller. That break lasts for the life of the equipment. The county expanded it under a Board of Supervisors vote in December 2025.
We install many types, for homeowners and business owners alike, from roof-mounted panels to full battery backup systems. As trusted solar panel installers Loudoun County, VA, we size every system to the property. Our solar installation services cover roof mounts, ground mounts, battery backup, and financed lease or PPA systems for residential and commercial customers.
It's a system sized to one Loudoun household, not a generic package. We design around your roof, your Dominion usage, and your HOA rules in neighborhoods like Ashburn or Broadlands. Homeowners can choose Cash, Loan, PPA, or Lease. Most residential solar systems qualify for net metering and Loudoun's property tax exemption.

It's a system built for a Loudoun business, not a household. We work with offices and small businesses along the Route 28 and Route 7 corridors. Businesses that own their system can still claim a 30% federal credit through 2027 under Section 48E. Commercial solar systems also qualify for net metering and Virginia's sales tax exemption.

It's a Level 2 charger installed at your Loudoun home or business. The federal 30C tax credit expired on June 30, 2026, so it no longer applies. Dominion Energy still pays a $125 rebate for a qualifying smart charger, plus $40 a year to stay enrolled. We size the charger to your panel and your EV, whether residential or commercial.

It's the most common setup we install for both homes and small commercial buildings. Panels sit right on the roof and tie into the Dominion grid. It qualifies for net metering and Loudoun's property tax exemption, and it usually clears HOA review fastest for residential properties.

It's built on the ground, not the roof. We see these most on larger residential lots out west, past Middleburg and Round Hill, and on commercial sites with open land. Ground mounts require an additional zoning permit and a site plat before work begins.

Fast and Furious Solar Installation
It’s a four-step process, start to finish. Every solar installation Loudoun County, VA, follows the same path: assessment, permitting, installation, and inspection. Most homeowners are producing their own power within six to eight weeks, and commercial timelines follow a similar sequence, adjusted for system size.
We look at the roof, the usage, and the budget, whether it’s a home or a business. A technician checks roof pitch and shading, especially from mature trees common in eastern Loudoun. We pull your Dominion usage history and walk through Cash, Loan, PPA, and Lease options. You leave with a real system design, not a guess.
Permits for Loudoun projects go through the county’s LandMARC system. Our team explains every step so you know what to do. A roof-mount permit runs 1% of the construction cost plus a $130 plan review fee. Electrical permits are a flat $165. Ground mounts also need a $165 zoning permit. If you’re in an HOA, check architectural approval separately, since the county permit doesn’t cover it. Commercial projects follow the same LandMARC process, sized to project value.
Our crew mounts panels and wires the system, usually in one to two days for a home and longer for larger commercial roofs. That includes the inverter, conduit, and battery if you added one. Every system we install is insured through our partnership with Align Solar, so you’re covered from day one.
The county inspects, then Dominion turns on net metering. Loudoun schedules inspections through LandMARC, Monday through Friday, 8:30 a.m. to 3 p.m. Once it passes, we submit your interconnection paperwork to Dominion. We also guide homeowners through filing for Loudoun’s property tax exemption the following year. For businesses, our team helps track federal credit paperwork.
