Not in Delaware?

Delmarva's standard offer supply rates jumped 19 to 20% on June 1, 2026, and Delaware still runs the Mid-Atlantic's last big upfront solar grant: $0.70 per watt, up to $6,000. Stack the 10-year-locked SREC auction and full retail net metering on top, and the First State quietly has one of the best deals going. EcoGen America shows you the current numbers and the installers who can actually file the paperwork.

About EcoGen America

In Delaware, Your Utility Decides Your Grant.

Delaware’s headline incentive is upfront cash: the Green Energy Program pays Delmarva customers $0.70 per watt, up to $6,000, off the cost of a residential system. But it is utility-specific: Delaware Electric Cooperative and the municipal utilities run their own versions with their own budgets and rules.

On top of the grant, every 1,000 kWh your system produces earns an SREC sold through SREC Delaware’s annual procurement, which locks your price, recently around $30, for the first 10 years. Net metering credits exports at the full retail rate.

And the grid price you are offsetting just moved: Delmarva’s standard offer supply rates rose 19 to 20% on June 1, 2026. Every kilowatt-hour your roof produces now avoids a noticeably bigger bill.

EcoGen America confirms which program your utility runs, checks your quote against real Delaware pricing, and matches you with installers who file the grant and SREC paperwork your return depends on.

Our vetting process

Grant-Fluent Network

Every installer we list can file your Green Energy Program application and your SREC Delaware registration, not just hang panels.

Quote Analysis

Built-in checks for missing grant applications, skipped SREC registrations, hidden dealer fees and quotes still modeling the expired federal credit.

Utility-Correct Numbers

Delmarva, the co-op and the municipals each run different grant and net metering rules. We model the program that actually applies to your address.

Privacy First

Your information goes only to the installers you choose to hear from. Nothing is resold.

June 1 Moved the Goalposts for Delmarva Customers

Delaware approved new standard offer service rates that took effect June 1, 2026, after regional supply auctions came in high. If you buy your power from Delmarva at the standard rate, here is what changed.

Standard Offer Supply Rate
Before June 1
After June 1
Change
Residential, summer
9.36¢/kWh
11.11¢/kWh
+19%
Residential, winter
9.48¢/kWh
11.40¢/kWh
+20%
Residential heating, summer
9.34¢/kWh
11.02¢/kWh
+18%
Residential heating, winter
8.58¢/kWh
10.05¢/kWh
+17%
Supply-portion rates from the State of Delaware’s April 2026 announcement; the average overall bill rises about 9%, roughly $14.64 a month. Delivery charges come on top, which is why the all-in Delaware average sits near 18.8¢/kWh.

Two consequences. Solar payback in Delaware just got faster, because every self-consumed kilowatt-hour now avoids a bigger charge. And savings projections written before June 1 are stale; make any installer re-run yours at the current rates.

Claim, Lock, Verify: The Delaware Sequence

1

Claim

Confirm which utility serves you and what its grant program pays right now. The Green Energy Program runs on budget cycles; your installer files the application before installation, not after.

2

Lock

Register with SREC Delaware's procurement so your SREC price locks for the first 10 years. Skipping or botching this filing quietly costs thousands over the contract.

3

Verify

Before signing, check the quote against Delaware's price band, confirm the savings model uses the post-June-1 rates, and get the cash price next to the financed price.

One Roof, Three Checks: How Delaware Stacks Up

Delaware is one of the few states left where solar pays upfront, monthly and annually at the same time. The three streams are separate programs with separate paperwork, and you are eligible for all of them at once.

Stream
What It Pays
When
The Paperwork
Green Energy Grant
$0.70 per watt, capped at $6,000, for Delmarva customers
Once, upfront
Application filed by your installer before installation
SRECs
One credit per 1,000 kWh; recent auction pricing near $30, locked for the first 10 years, lower flat rate after
Ongoing income
Registration through SREC Delaware’s annual procurement
Net metering
Full retail credit for every exported kilowatt-hour
Monthly, on the bill
Interconnection filed with your utility
Grant terms per DNREC’s Green Energy Program for Delmarva customers; co-op and municipal customers have parallel programs with different amounts. SREC structure per SREC Delaware. Delaware also charges no sales tax on anything, solar included.

The order matters: grant application before installation, SREC registration at commissioning, interconnection before permission to operate. An installer who has done all three in Delaware is worth more than a cheaper one who has not.

Delaware Contract Checks

Pin These Down Before Signing in Delaware

Delaware's stack is generous but paperwork-heavy, and it differs by utility. Every quote should answer these four in writing.

Clause to verify: Does the quote name your utility and its current grant terms, and has the installer confirmed budget is available this cycle?
Clause to verify: Get in writing who files the Green Energy Program application and the SREC Delaware registration, and by when.
Clause to verify: Does the model use the current post-June-1 rates for your utility, and what escalator does it assume? Ask for a re-run at 2%.
Clause to verify: Request the cash price in writing next to the financed total, and compare the gap against the stated interest.
Verify your paperwork

Run these on any Delaware quote. If the contract cannot answer all four, keep shopping.

Who Shouldn’t Rush Into Delaware Solar

The grant creates urgency, and salespeople know it. Here is who should slow down anyway.

  • Co-op and municipal customers who were quoted Delmarva math. Delaware Electric Cooperative and the municipal utilities run their own grant and net metering rules. A projection built on the Delmarva program does not transfer; get your utility’s terms in writing first.
  • Anyone told to sign today because the grant is running out. Grant budgets do cycle, but the math either works at current terms or it does not. If funds are exhausted, the numbers without the grant are the numbers; decide on those, not on urgency.
  • Roofs with under 10 to 15 years left. Removing and reinstalling panels mid-life costs thousands no warranty covers. Delaware’s grant does not pay twice.
  • Low-usage homes. A small bill leaves little to offset, and fixed delivery charges remain. The grant softens the entry price; it cannot manufacture savings that are not there.
  • Owners planning to move within several years. The SREC contract and the payback both reward staying put. Selling early transfers the income stream with the house, not with you.

Worth knowing either way: Delaware charges no sales tax on your system because it charges no sales tax on anything, and the federal 30% credit is gone as of December 31, 2025, for purchased systems, so the state stack is the whole stack now. See the Delaware incentives guide for the current program detail.

Delaware Solar FAQs

How does the Delaware Green Energy Grant actually work?

Delmarva residential customers get $0.70 per watt, capped at $6,000, off a qualifying system. Your installer files the application with the program before installation, and the grant comes off the project cost.

Funding runs on program budget cycles, so have your installer confirm availability in writing before you count on it.

What are Delaware SRECs worth, and for how long?

Each 1,000 kWh your system produces earns one SREC, sold through SREC Delaware’s annual procurement. Recent pricing has run near $30, and your auction price locks for the first 10 years, with a lower flat rate for the years after.

Registration is separate from the grant and from interconnection. Confirm who files it, because a missed registration is a decade of lost income.

I’m not a Delmarva customer. Do I still get the incentives?

You still earn SRECs and you still get net metering, but the grant differs: Delaware Electric Cooperative and the municipal utilities run their own programs with their own amounts, rules and budgets.

Get your utility’s current terms directly from the utility before comparing quotes, and treat any Delmarva-based projection as the wrong math for your house.

Did the June 2026 rate increase change whether solar is worth it here?

It strengthened the case. Delmarva’s standard offer supply rates rose 19 to 20% on June 1, 2026, about $14.64 a month on a typical bill, and every kilowatt-hour your panels produce now offsets that higher rate.

It also dated every projection written before June 1. Make any installer re-run your savings at the current rates before you sign.
