In Delaware, choosing a solar company means choosing someone who knows your utility’s grant program cold. The Green Energy Grant pays $0.70/W up to $6,000 while funds last, the terms shifted for Delmarva customers on June 1, and SRECs lock near $30 for 10 years. The paperwork order decides real money.
Generic lists rank Delaware installers without once mentioning the grant calendar. That misses what actually goes wrong in Delaware: grants assumed without reservations, SREC registrations filed late or not at all, and quotes that never say which utility’s program year they are spending.
Here is how we evaluate Delaware installers, the three companies in our network today, and the questions that pin a Delaware quote to the ground. For the grant-by-grant math, start with our Delaware solar guide.
The Paperwork Test for Delaware Installers
Small state, layered paperwork. We look at four things, all checkable:
- Licensing. Delaware electrical work traces to licensed electricians through the state’s Division of Professional Regulation; ask for the license and match the business name to your contract.
- Grant fluency. Does the company file your Green Energy Grant reservation before construction, and can it say what remains in your utility’s current program year?
- SREC handling. Delaware’s ~$30 10-year SREC lock only pays if registration happens; ask who files and when.
- Published warranty terms. Workmanship coverage in writing, with the labor and equipment split stated plainly.
Two Locals and a Nine-State Operator
Alphabetical and unpaid, with no numbered ranking until our scoring methodology publishes. Every profile below is built from the company’s own materials.
Clean Energy USA
Delaware-based since 2007 with thousands of installations across the state, Clean Energy USA publishes ongoing guidance on Delaware’s SREC program and state grants, and offers battery storage and EV charging alongside rooftop solar. A statewide Delaware specialist whose paperwork rhythm matches the programs above is exactly the profile this market rewards.
CMI Solar & Electric
One of Delaware’s longest-running solar contractors, installing from its Newark headquarters since 1998, CMI runs in-house licensed electricians across solar, storage and electrical upgrades, publishes a 5-year labor and 25-year equipment warranty split, and participates in Delaware’s income-qualified LMI solar program. Twenty-eight years in a small state means your references live nearby.
Trinity Solar
Operating since 1994 out of Wall Township, NJ, Trinity is one of the largest privately held residential installers in the country and publishes its state electrical and home improvement licenses for all nine states it serves, Delaware included, with a 25-year workmanship warranty and an 8-to-10-week published timeline. Scale brings deep permitting experience; ask who actually shows up on your roof.
Grant-Season Questions for Any Delaware Rep
- “Is my Green Energy Grant reserved, and from which program year?” The $0.70/W grant runs while funds last, and Delmarva’s terms moved on June 1. “You’ll probably get it” is not a reservation.
- “Who registers my SRECs, and when?” The ~$30, 10-year lock is real money that only flows after registration. The filing belongs to a named person on a date.
- “Which utility am I under, and does your math match its program?” Delmarva, DEMEC municipals and the co-op run different flavors; the quote should name yours.
- “What is the labor-versus-equipment warranty split?” Delaware quotes vary widely here; get both numbers in writing.
- “Does your quote still show a federal tax credit?” Section 25D expired December 31, 2025. Any homeowner-owned quote showing a 30% federal reduction is wrong, and so is every payback under it.
When the Smart Delaware Move Is Waiting a Cycle
If the current grant year is exhausted and your math only works with the grant, waiting for the next funding cycle beats borrowing against hope. Shaded lots, roofs due for replacement and near-term moves round out the honest wait list. Our Delaware guide covers who shouldn’t rush, and when patience literally pays $6,000.
Delaware Installer Questions, Answered
How do I verify a Delaware solar company’s license?
Delaware electrical licenses run through the state’s Division of Professional Regulation; ask the installer for the license number and confirm the business name matches your contract.
Out-of-state firms should show Delaware credentials specifically, not a neighboring state’s.
Should I choose a local Delaware installer or a multi-state company?
Both models work here: CMI and Clean Energy USA are Delaware institutions with decades of grant and SREC paperwork behind them, while Trinity brings nine-state scale and published licensing.
What decides it: who reserves your grant before construction and files your SRECs on a named date.
What does a fair Delaware solar quote look like in 2026?
Cash pricing typically runs $2.50 to $3.10 per watt. See our breakdown at cost-of-solar-panels/delaware.
The quote should show the Green Energy Grant as a reserved amount, the SREC income stream, and no dead federal credit.
Is the Delaware Green Energy Grant still available?
The program pays $0.70 per watt up to $6,000 while each program year’s funds last, and terms shifted for Delmarva customers in June.
Availability is a live question every month, which is why a reservation, not a promise, is the standard your installer should meet.
Three real companies serve Delaware well: two in-state veterans and a nine-state operator that publishes its licenses. The one that deserves your roof reserves the grant before construction, files the SRECs on a date, and says which program year it is spending.
Before you talk to any of them, know your numbers: check Delaware’s incentives, see what systems cost here, and get an independent read on your grant timing through our Delaware solar report. In a while-funds-last state, the calendar is part of the price.
