When could Delaware get a plug-in law?
Past bills
- SB 270 (2026). A bill (SB 270) was introduced in 2026 and is still in committee. The session ended on Jun 30, 2026, and bills don't carry over to the next General Assembly. The Senate also passed a resolution (SR 21) asking the Delaware Sustainable Energy Utility to study plug-in solar safety and report by Jan 26, 2027. legis.delaware.gov
The 10 plug-in solar laws signed in other states follow a common pattern: a size cap (1,200 W in 9 of them), a safety certification for the device (10 of 10), and no utility approval needed (9 of 10). See every state's law and bills on the map.
Federal bill, not law
The federal bill: H.R. 10851
H.R. 10851, the Socket Full of Sunshine Act, was introduced in the House by Rep. Rob Menendez (D-NJ-8) on Oct 19, 2026 and referred to the Committee on Energy and Commerce. It has no cosponsors and has not passed the House or the Senate.
If it became law, it would require every state to consider rules for plug-in solar devices of up to 1,200 W, such as dropping interconnection agreements and utility approval, fees, insurance and extra equipment. Considering is not adopting: even if it passes, it would not make plug-in solar legal in Delaware by itself.
It would also offer grants to states that set up rebate programs for low- and moderate-income households. None of this exists unless the bill passes, and even then a rebate in Delaware would depend on the state applying for a grant.
