Net metering in Delaware, provider by provider.
Every provider in the state, and every figure below read from the published tariff or interconnection document rather than a comparison site. Some credit you the full retail rate for the power you send back. Most do not, and that difference is the whole reason this page exists.
Meter reading falling from 41926 to 41672 kilowatt hours. A 911 kilowatt hour month against 1,165 kilowatt hours produced leaves 0 kilowatt hours billed and 254 banked for next month, so the energy charge falls from $175.73 to $0.00 at 19.29 cents per kilowatt hour.
Delaware average household use, 911 kWh a month, at the current published residential price of 19.29¢ per kWh. Your utility still bills a fixed monthly customer charge that no system offsets, so this is the energy part of the bill, which is the part that goes away.
Solar buyback rates in Delaware, utility by utility
Delaware credits a month’s excess in kilowatt hours, valued at the per kWh supply and delivery charges, at every utility in the state. A 2025 law (SB 175) ended the forfeiture of unused credits at the end of each 12-month period and gave utilities until 1 December 2026 to change their billing. It also removed the 110% sizing limit from the statute, although both utilities’ tariffs still carry it.

Net metering in Delaware: the questions people ask
- Does Delaware have net metering?
- Delaware credits a month’s excess in kilowatt hours, valued at the per kWh supply and delivery charges, at every utility in the state. A 2025 law (SB 175) ended the forfeiture of unused credits at the end of each 12-month period and gave utilities until 1 December 2026 to change their billing. It also removed the 110% sizing limit from the statute, although both utilities’ tariffs still carry it.
- What is the solar buyback rate in Delaware?
- It is set utility by utility, not by the state. How the 2 providers we list in Delaware credit the power you export: 2 at the full retail rate. Each one’s own page gives its figure and the date we read it.
- Is solar worth it in Delaware in 2026?
- It depends mostly on what your utility pays for the power you export, because the 30% federal credit ended for systems completed after 31 December 2025. Delaware homes use about 911 kWh a month at an average of 19.29 cents per kWh, according to the U.S. Energy Information Administration. Where exports are credited at the full retail rate, each kilowatt hour your panels send back is worth about that much; where they are credited below retail, size the system to what you use while the sun is up. Check your own utility on this page before you get a quote for solar panels.
- Is there a solar tax credit in Delaware in 2026?
- Not a federal one. The 30% federal credit, IRC Section 25D, ended for systems completed after 31 December 2025, and a deposit paid in 2025 does not preserve it. Anyone still quoting it is working from an old script. Any incentive left in Delaware comes from the state or your utility, and what your utility pays for exported power is now most of the financial case.
- Which providers does the Delaware rule cover?
- Delmarva Power, Delaware Electric Cooperative and the municipal systems, each through its own net metering tariff under the statute.
- What happens to credits you do not use in Delaware?
- Excess kWh credits carry to later bills, and under the 2025 law from one 12-month period to the next. None is paid. The utilities’ tariffs still say unused credits revert at the end of each 12-month period; the 2025 law says they carry over, with billing changes due by 1 December 2026.
- How big a solar system can you install in Delaware?
- Residential systems up to 25 kW AC. Both utilities’ tariffs also limit a system to 110% of average annual use over the previous two years, a limit the 2025 law removed from the statute.
- Which electricity providers does this cover in Delaware?
- We have read the published terms of 2 providers in Delaware: Delmarva Power, Delaware Electric Cooperative. Each has its own page with the figures taken from its own tariff or from the state’s own order.
