The only requirement to appear on this page is a checked state electrical license, confirmed against the state licensing board as part of our approval process, that's why every listing above shows "License checked." Installers are listed alphabetically by default, not ranked by quality, and no installer pays for placement in that order. LumoWatt does not sell ranking. If paid placement is introduced, it will be clearly labeled and will not change the standard list order. Use the sort dropdown above to re-order the list yourself by years in business or how recently we checked a listing. See our editorial policy and listing standards & verification methodology for the full details.

Virginia's outage risk varies by region: coastal Virginia Beach/Hampton Roads faces direct hurricane and tropical storm landfalls plus Nor'easter-driven flooding and wind outages, the Richmond area sees central-Virginia severe thunderstorm and occasional ice-storm outages, and Northern Virginia's dense DC-metro suburbs face their own mix of derecho-type severe wind events and ice storms layered onto much higher grid demand and redevelopment pressure than the rest of the state.
