New to plug-in solar?

Plug-in solar lets anyone generate free electricity — no roof, no permit, no contractor. A single panel on your balcony can meaningfully cut your bill, especially as rates keep rising.

Coming Soon — Delaware is considering plug-in solar legislation

Would permit residential plug-in solar systems up to 800W without utility approval or interconnection requirements. Stalled in the Senate Energy & Transit Committee without a vote before the 2026 session's practical cutoff; sponsors have said they plan to reintroduce it.

Solar you can use in Delaware today, while you wait

Plug-in solar that ties into your home's wiring isn't legal here yet — but a portable solar generator (a panel charging a battery you plug devices into directly) never touches your home's wiring, so it's legal everywhere, including Delaware, right now.

What to Expect If This Passes

🔌

Up to 800W, no permit

The bill as drafted would allow systems up to 800W AC connected to a standard household outlet — no permit, no utility approval required.

⚡

No net metering

The bill does not include net metering for plug-in systems. Excess generation would not be credited. Self-consumption maximization is key.

🏠

Renters included

The bill does not restrict installation to homeowners. Renters would still need landlord consent, but no permanent installation is required.

ℹPanels typically last 25–30 years with a 25-year output warranty. Microinverters carry a 10–25 year warranty depending on brand. Battery modules degrade faster — expect 10–15 years before capacity drops below 80%. The 25-year savings figure above assumes the panel and inverter run for the full window; budget ~$200–$400 for an inverter swap around year 15 if needed.

Frequently Asked Questions

Can a Delaware HOA prevent me from installing solar panels?
No. Delaware House Bill 65 (2019) prohibits homeowner associations from restricting the installation of roof-mounted or ground-mounted solar panels on private residences.
Is plug-in or balcony solar specifically addressed under Delaware law?
Not yet enacted. SB 270, introduced in 2026, would create an 800W-cap 'portable solar generation device' category exempt from interconnection agreements and utility pre-approval, but it remains in the Senate Energy & Transit Committee with no vote scheduled as of mid-2026. Delaware's existing HB 65 and net metering rules were written for conventional solar installations and don't address small plug-in devices.
Does Delmarva Power offer net metering for small solar systems?
Yes, net metering is available for residential systems up to 25kW, with excess production credited in kilowatt-hours. A 2025 PSC update revised system size limits and interconnection procedures, and an ongoing cost-benefit study (from SJR 1) may affect future policy.
Would I need Delmarva Power's approval to use a small plug-in solar panel?
Under current rules, any device that interconnects with household wiring would generally fall under Delmarva's standard interconnection requirements, since Delaware has no plug-in-solar-specific exemption yet.
