Deep Dive: Do I Have to Tell My Utility About Plug-In Solar? Notice vs. Approval by State

Описание: “No utility approval required” is not a universal permission slip. In this episode, Lisa and Mike separate the processes that are often confused: utility notice, registration, approval, interconnection agreements, fees, and the separate code, fire, local, landlord, lease, or HOA questions that a state utility exemption does not settle. 


The guide compares five enacted frameworks—Maryland, Connecticut, Maine, Colorado, and Virginia—using their different deadlines, output limits, notice sequences, and eligibility conditions. Maryland requires notice before installation. Maine’s higher-output pathway requires notice within 30 days after installation. Colorado permits a provider to require notice but not prior approval for a qualifying device. Connecticut’s qualifying-device provision becomes effective October 1, 2026. Virginia’s notice process begins January 1, 2027 and is not current installation authorization.


The discussion is about qualifying devices and enacted frameworks, not legal advice or an electrical design. Before purchase or installation, match the exact device, output, outlet or circuit plan, serving utility, meter treatment, and property rules to the current requirements for the address.

Key Takeaways


1. Notice and approval are different actions. A state may require notice, remove an approval or agreement step for a qualifying device, or create a framework that is not effective yet. Those outcomes should not be treated as interchangeable.


2. The state sequence matters. Maryland uses advance notice. Maine’s notice applies within 30 days after installation when combined inverter output exceeds 420 watts. Colorado permits provider notice. Connecticut’s provision takes effect October 1, 2026, and Virginia’s begins January 1, 2027.


3. Keep utility rules separate from safety and property rules. A qualifying-device utility exemption does not automatically settle product listing, circuit suitability, code, fire, permit, meter, tariff, landlord, lease, HOA, or local-authority requirements.
