Delaware community solar rules and the 2026 billing law (SB 321)

See if I qualify

What did SB 321 change, and when?

SB 321 was signed on Aug 27, 2026 as 85 Del. Laws c. 448. It is now part of the Delaware Code at 26 Del. C. §1022.

Which projects get one bill by default, and which may opt out?

Projects certified on or after Sept 3, 2026 get one Delmarva bill by default. Projects certified on or before Sept 2, 2026 may opt out. No start date for one-bill billing has been announced, so subscribers generally get two bills today: the Delmarva bill with the credit, and a bill from the project. See how the credit shows on your Delmarva bill.

What savings floors apply, by project date?

The PSC list dated May 6, 2026 shows 34 projects certified from June 12, 2024 to March 25, 2026. None of them falls under the new floor. The law does not define what the savings rate is measured against, so read it as a discount on the solar credit, not on your whole bill. See who counts as income-qualified.

What consumer protections apply?

• No project or subscription coordinator may require a residential subscriber to pass a credit check or pay an upfront enrollment fee (§1022(c)(1)).
• Security deposits are banned (Reg 3013 §16.6).
• Total cost to a subscriber, coordinator fees included, may not exceed the total benefit (Reg 3013 §16.5).
• Marketing in any medium, websites and social media included, may not suggest a relationship with Delmarva, a government agency or another project that does not exist, or say you must choose a particular party (Reg 3013 §16.4.2.1, §16.4.2.3).

What are the rules for subscription coordinators?

A subscription coordinator is a person with a contract with a project to provide services such as marketing it under its own brand, enrolling customers, or handling the utility. Under Reg 3013, coordinators need PSC approval before acting:

• No application fee, and a surety bond of at least $50,000.
• A decision 60 days after a complete application, plus up to 60 more days.
• Applications are filed through DelaFile. Existing coordinators had to apply by May 12, 2026.
• PSC staff may publish a list of approved coordinators. As of October 13, 2026, none was posted.

Projects and coordinators answer for deceptive acts by their agents, including lead generation firms. Violations are unlawful under 6 Del. C. §2513.

What hasn't changed?

• Only customers with a Delmarva Power account in Delaware can join.
• Only projects with a PSC Final Certificate to Operate may enroll customers.
• The credit is your share of project output times the per-kWh distribution and supply charges on your rate schedule. Fixed charges are not offset.
• Credits are capped at 110% of expected use, and you may join up to 4 projects.

What is still open?

• No start date for one-bill billing has been announced.
• The enacted bill text says "on or after September 2, 2026", while the codified §1022(c)(2) says September 3. This page uses September 3. It matters only for a project certified on exactly September 2, 2026.
