Solar Inverter Replacement in Annandale, VA
If your solar panels are up on an Annandale roof but nothing is reaching the house, the inverter is the likely culprit. Solar Inverter Replacement swaps out the failed unit for a matched one so your panels feed power back into your home. Annandale sits in a county rated Very High for winter storms and lightning, and those surges are hard on electronics, so a dead inverter here is common enough to plan for.
About this service
Solar Inverter Replacement in Annandale
We match the new unit to your existing array so it works with the panels, wiring and utility connection you already have. In an area where many homes date back to around 1968, we check the connections and the mounting point too, because older wiring tends to show its age the moment a new component goes in.

Good to know
Solar Inverter Replacement in Annandale, Common Questions
Can a solar inverter really fail from a lightning strike in Annandale?
Yes, power surges from lightning and winter storms are a frequent cause of inverter failure in Fairfax County. A failed unit usually shows up as a dark display or a drop in output, and it's worth having it checked soon.
My house is older. Will a new inverter work with my existing wiring?
Often it will, but older Annandale homes sometimes need a closer look at the connections before a new unit goes in. We inspect the wiring as part of the replacement so the new inverter isn't stressed by problems that were already there.
What happens during a solar inverter replacement visit in Annandale?
A technician checks the failed unit, confirms the fault, and verifies the wiring, disconnects, and panel strings around it. Once the matched replacement is in hand, the old inverter comes off and the new one goes in. The system is started up and tested so you can see power flowing again before we leave.
How long does it take and what does it cost?
Most replacements are completed in a single visit, though timing depends on the unit's availability and your system's layout. We give you the scheduling details and the cost of the replacement by phone once we've confirmed your model. Call us and we'll walk through what to expect for your specific system.
