Is solar worth it in Ashburn, VA?

Is solar worth it in Ashburn? For a 9.5 kW system at about $27,550 making about 11,600 kWh a year on Dominion Energy at an average 14.1¢ per kWh, it depends on how much you use at home.

The honest answer · as of August 2026

For some Ashburn homes yes, for others no. Dominion Energy Virginia credits exports at credited one-for-one at retail against your own annual usage, so the deciding number is how much of the 11,600 kWh a 9.5 kW system makes here you use yourself. The median Ashburn home was built in 1999, so many roofs are reaching their second half. We check remaining roof life before we design.

Local verdict

The honest read on Ashburn

Ashburn is close to the best case we can point at anywhere in our territory, and the reasons are policy and roof stock rather than sunshine. Northern Virginia receives meaningfully less sun than the Carolinas, so a kilowatt of panel produces less here. Retail crediting more than compensates, because every kilowatt-hour it does produce is worth full retail rather than a fraction.

What decides an individual house is the roof and the covenant. Most Ashburn roofs are open, modern and well oriented, which removes the usual objection. The community guidelines are the live question, and SB 504 gives you numbers to argue with rather than an aesthetic debate you cannot win.

There is also a motivation here we do not see elsewhere. A household watching its bill climb because of load growth it has no say in is in a genuinely different position from one shopping on payback alone, and it is reasonable to weigh that.

What changed

What changed in 2026, and what it does to payback

The federal homeowner credit ended on December 31, 2025. Virginia has no state credit, so the export terms carry the case.

What decides it

Four things decide whether solar pays in Ashburn

What Dominion Energy credits for exports, how much of your 11,600 kWh you use at home, your roof (the median Ashburn home was built in 1999) and shade, and how long you will stay.

Two lists

Who solar suits in Ashburn, and who it doesn't

Solar usually makes sense for your Ashburn home if

  • Your bill is at or above roughly $135 a month, what a 9.5 kW system here offsets at Dominion Energy Virginia's average rate.
  • The median Ashburn home was built in 1999, so many roofs are reaching their second half. We check remaining roof life before we design.
  • Your best roof planes clear the shade: ashburn is master-planned and largely open, with thousands of near-identical modern roofs.
  • You use power in daylight, when a 9.5 kW system here makes up to about 1,226 kWh a month.
  • You plan to stay long enough to reach payback.

Solar is probably not right for you if

  • Mature hardwood shades your best roof planes for much of the day, which is common in the older parts of the county.
  • Your roof needs replacing within about five years.
  • You are likely to move within five years.
  • You need more than 15 kW AC and cannot get written confirmation that your utility has adopted the new 20 kW standby threshold yet.
  • Your meter turns out to be on NOVEC rather than Dominion and the cooperative’s terms do not support the size you had in mind.
  • You are being sold on a 30% federal credit: that quote is wrong.
