Got panels going on the roof in Towson, Catonsville, or Pikesville? The part that actually powers your house and passes inspection is the electrical work behind them — and that’s what David Williams Electric does. We handle the side a solar salesperson usually subs out: tying the array into your main panel the right way, setting the AC disconnect BGE wants to see, running the conductors, and wiring the meter so net metering credits you correctly. We don’t do roofing or racking. We do the licensed electrical hookup that makes a Baltimore County solar install safe, code-legal, and approved. Maryland license #11734, 30-plus years on the tools, a price quoted up front, and 100% satisfaction.
Where Baltimore County Solar Jobs Actually Get Held Up
Most solar headaches in this county aren’t on the roof — they’re at the panel. A lot of Baltimore County housing stock is older: 1950s–60s Cape Cods and ramblers around Parkville, Essex, and Catonsville, plus mid-century splits in Towson, many still running a 100-amp or aging 150-amp service. The National Electrical Code’s 120% rule limits how much solar backfeed a given busbar can take, and on those panels the math frequently doesn’t work without a line-side tap, a main-breaker downsize, or a service upgrade. We figure that out before the panels ever ship — not after the installer hits a wall.
The other snag is the disconnect. BGE expects a visible, lockable AC disconnect at the meter so their crews can isolate your system, and county inspectors check for it. We size and place it to BGE’s standard the first time, so your interconnection paperwork doesn’t bounce back.
What the Electrical Scope Covers
Our part of a solar install is the electrical spine of the system. That means the main-panel interconnection done to the NEC 120% rule — back-fed breaker, line-side tap, or a panel upgrade when the busbar can’t carry it. It means the BGE-spec AC disconnect, the conductor and conduit runs from array to inverter to panel, the equipment and grounding, and the net-metering wiring so your BGE bi-directional meter actually credits the power you send back.
If you’re going battery-ready, we wire in a hybrid inverter and a protected (backed-up) subpanel, so the circuits you care about — well pump, fridge, sump, a few lights — stay live when the grid drops. We’ll tell you straight whether your panel and service can take it, in plain numbers, before you commit.
Permits, BGE, and the HOA Reality Here
A compliant Baltimore County solar hookup runs through two gates: the county electrical permit and inspection out of Towson, and BGE’s interconnection and net-metering approval. We pull the electrical permit, build the system to pass the county inspector, and provide the documentation BGE needs to set your net meter and switch you on. When a job stalls, it’s almost always a missing disconnect, an undersized service, or an interconnection form that doesn’t match what’s actually installed — all things that live on our side of the work.
Plenty of Baltimore County neighborhoods — newer developments around Owings Mills and Reisterstown especially — sit under an HOA with rules on conduit routing and visible equipment. We keep runs tidy and disconnects placed sensibly so the install reads clean, while still landing exactly where code and BGE require.
One Licensed Electrician, Start to Inspection
You can hire a national solar outfit and let them sub the wiring to whoever’s free that week, or you can have a licensed Baltimore County electrician own the electrical side from panel assessment through final inspection. We work alongside your roofer or installer, or pick up the hookup after the panels are mounted — whichever fits your job.
Maryland license #11734, more than 30 years of residential work in this county, an up-front price with no surprise add-ons, and a 100% satisfaction guarantee. Call David Williams Electric and we’ll tell you exactly what your panel and your BGE service need.
Frequently Asked Questions
Do you install the solar panels and racking too?
No — we're electricians, not a roofing crew. We handle the licensed electrical side: tying the array into your main panel under the NEC 120% rule, the BGE AC disconnect, conductor runs, net-metering wiring, and battery/hybrid-inverter hookups. We work right alongside your panel installer or pick up the wiring after the panels are mounted.
Will my older Baltimore County home's electrical panel handle solar?
Often it needs a look first. A lot of homes around Parkville, Essex, and Catonsville still run 100-amp or aging service, and the NEC 120% rule caps how much solar a panel's busbar can take. We assess your service and tell you up front whether a back-fed breaker works as-is or you'll need a line-side tap or a panel upgrade — before the project gets going, not mid-install.
What does BGE require for a grid-tied solar system?
BGE wants a visible, lockable AC disconnect at the meter so their crews can isolate your system, plus an interconnection application and a bi-directional (net) meter. We build the electrical side to that standard and supply the documentation BGE needs, so your net-metering approval and switch-on aren't held up by a paperwork mismatch.
Can you make my system battery-ready for outages?
Yes. We wire in a hybrid inverter and a protected subpanel so chosen circuits — fridge, well pump, sump, key lights — stay powered when the grid goes down. We'll confirm your panel and service can support it first and give you a straight answer in plain numbers.
Do you pull the permit and handle the inspection?
Yes. We pull the Baltimore County electrical permit, build the work to pass the county inspector out of Towson, and provide what BGE needs for interconnection and net metering. The electrical permit and inspection are on us — your install moves through both gates cleanly.
