Solar Incentives
in Delaware.
Delaware targets at least 40% renewable energy by 2035 — and backs it with utility grants, SREC income, net metering, and zero sales tax. Headquartered in Wilmington, Zenergy knows every program in the First State.
Delaware Utility Rebates
Delaware doesn't run a single statewide rebate — each utility administers its own grant program. Your rebate depends on who delivers your power.
| Utility Provider | Rebate Rate | Maximum |
|---|---|---|
| Delmarva Power (Green Energy Grant) | $700 per kW | $6,000 |
| DEMEC Municipal Utilities | $1,000 per kW | $3,500 |
| Delaware Electric Cooperative | $500 per kW | $2,500 |
Incentives That Keep Paying
Rebates lower the upfront cost — these programs keep working for the life of your system.
Income for Every MWh
Delaware SRECs
For every megawatt-hour your system generates, you earn one Solar Renewable Energy Certificate sold through Delaware’s state-run SREC procurement. Recent program pricing has run around $30 per SREC for the first 10 years, then $10 per SREC for years 11–25.
Full Retail-Rate Credits
Net Metering
Delaware utilities credit surplus solar at the full retail rate, and unused credits roll forward. Summer overproduction offsets winter usage, which is how well-sized systems reach a near-zero annual bill.
Keep What You Save
Tax Advantages
Delaware has no state sales tax, so nothing is added to your equipment cost. Most jurisdictions also exempt the home value solar adds from property tax assessment.
What Happened to the 30% Federal Tax Credit?
The federal rules changed at the end of 2025. Here's the honest picture — and how homeowners still capture federal value in 2026.
Ended Dec 31, 2025
The 30% Residential Clean Energy Credit (Section 25D) for homeowner-purchased solar — and the Section 25C credit for heat pumps and insulation — ended for systems placed in service after December 31, 2025. Systems installed in 2025 can still be claimed on your 2025 tax return.
Still Available in 2026
Third-party-owned systems — solar leases and power purchase agreements (PPAs) — remain eligible for the federal Section 48E credit through 2027. The system owner claims the credit and passes the value through as a lower monthly rate. State incentives, SRECs, utility rebates, and net metering are unaffected.
Compare Ownership vs. Lease*Tax law changes and individual eligibility vary. Confirm your situation with a certified public accountant (CPA) before relying on any tax benefit.
Delaware Incentive FAQs
How much is the Delmarva Power Green Energy Grant?
Delmarva Power’s Green Energy Program has offered $700 per kilowatt installed, up to $6,000 per residential project. DEMEC municipal utilities and Delaware Electric Cooperative run their own versions at different rates. Program funding cycles change, so we confirm current availability before your proposal is finalized.
Who files the rebate and SREC paperwork?
Zenergy does. We submit your utility grant application, register your system with the SREC Delaware program, and provide every document your CPA needs. You sign — we handle the rest.
Is the 30% federal solar tax credit still available in Delaware?
The residential credit (Section 25D) ended for systems placed in service after December 31, 2025. Leased and PPA systems remain eligible for the federal Section 48E credit through 2027, with the savings built into your monthly rate. Delaware’s state and utility incentives are unaffected.
Are there restrictions if I’m a Delaware Electric Cooperative member?
Co-op members can absolutely go solar, but the co-op runs its own interconnection and rebate rules. We work in DEC territory regularly and walk you through the specifics during your free consultation.
